  • iPhone Adding Controls (UIButton, UILabel etc.) on a Playing Video!

    - by Taimur Hamza
    I have been assigned an 'easy' task of adding a button over a playing video. I m terming it easy as i have got the sample code downloaded from Apple's sample code. http://rapidshare.com/files/393248642/MoviePlayer_iPhone.zip Anybody who wants to reply to my query and intends to help should download this project and run it otherwise it wudnt be easy to understand my problem. Thanks! And now the weird problem i am facing is: In the sample project developer has added the view ( UILabel and UIButton ) in the Appdelegate. And i want it other xib files not the App delegate . Fine i added a view 'myButtonABC' instead of 'My Overlay View'. And added this code in my xib file's implementation file. (void)viewDidLoad { TaimurAppDelegate *appDelegate = (TaimurAppDelegate *)[[UIApplication sharedApplication] delegate]; [appDelegate initAndPlayMovie:[self localMovieURL]]; NSArray *windows = [[UIApplication sharedApplication] windows]; if ([windows count] 1) { UIWindow *moviePlayerWindow = [[UIApplication sharedApplication] keyWindow]; [moviePlayerWindow addSubview:self.myABC]; } } Now my question is do i need to declare a UIWindow object in the header file here. As i am not working in the app delegate class. As i said previously i have to add this button over a video in other screen and not on the main screen. The third question is can anyone, which in fact is the most imp of all. In my view , if i am able to do this one my problem would be solved. As i have spend considerable amount of time on this task so far. The question is " How can i connect myABCButton (which is a view added to my xib file ) to the File's Owner. Thanks for your patience. Replies Appreciated ! Taimur

  • Cross-thread operation not valid: accessed from a thread other than the thread it was created on.

    - by user307524
    Hi, I want to remove checked items from checklistbox (winform control) in class file method which i am calling asynchronously using deletegate. but it showing me this error message:- Cross-thread operation not valid: Control 'checkedListBox1' accessed from a thread other than the thread it was created on. i have tried invoke required but again got the same error. Sample code is below: private void button1_Click(object sender, EventArgs e) { // Create an instance of the test class. Class1 ad = new Class1(); // Create the delegate. AsyncMethodCaller1 caller = new AsyncMethodCaller1(ad.TestMethod1); //callback delegate IAsyncResult result = caller.BeginInvoke(checkedListBox1, new AsyncCallback(CallbackMethod)," "); } In class file code for TestMethod1 is : - private delegate void dlgInvoke(CheckedListBox c, Int32 str); private void Invoke(CheckedListBox c, Int32 str) { if (c.InvokeRequired) { c.Invoke(new dlgInvoke(Invoke), c, str); c.Items.RemoveAt(str); } else { c.Text = ""; } } // The method to be executed asynchronously. public string TestMethod1(CheckedListBox chklist) { for (int i = 0; i < 10; i++) { string chkValue = chklist.CheckedItems[i].ToString(); //do some other database operation based on checked items. Int32 index = chklist.FindString(chkValue); Invoke(chklist, index); } return ""; }

  • Can I use a static cache Helper method in a NET MVC controller?

    - by Euston
    I realise there have been a few posts regarding where to add a cache check/update and the separation of concerns between the controller, the model and the caching code. There are two great examples that I have tried to work with but being new to MVC I wonder which one is the cleanest and suits the MVC methodology the best? I know you need to take into account DI and unit testing. Example 1 (Helper method with delegate) ...in controller var myObject = CacheDataHelper.Get(thisID, () => WebServiceServiceWrapper.GetMyObjectBythisID(thisID)); Example 2 (check for cache in model class) in controller var myObject = WebServiceServiceWrapper.GetMyObjectBythisID(thisID)); then in model class.............. if (!CacheDataHelper.Get(cachekey, out myObject)) { //do some repository processing // Add obect to cache CacheDataHelper.Add(myObject, cachekey); } Both use a static cache helper class but the first example uses a method signature with a delegate method passed in that has the name of the repository method being called. If the data is not in cache the method is called and the cache helper class handles the adding or updating to the current cache. In the second example the cache check is part of the repository method with an extra line to call the cache helper add method to update the current cache. Due to my lack of experience and knowledge I am not sure which one is best suited to MVC. I like the idea of calling the cache helper with the delegate method name in order to remove any cache code in the repository but I am not sure if using the static method in the controller is ideal? The second example deals with the above but now there is no separation between the caching check and the repository lookup. Perhaps that is not a problem as you know it requires caching anyway?

  • Implementation of delegates in C#

    - by Ram
    Hi, I am trying to learn on how to use delegates efficiently in C# and I was just wondering if anyone can guide me through... The following is a sample implementation using delegates... All I am doing is just passing a value through a delegate from one class to another... Please tell me if this is the right way to implement... And also your suggestions... Also, please note that I have de-registered the delegate in : void FrmSample_FormClosing(object sender, FormClosingEventArgs e) { sampleObj.AssignValue -= new Sample.AssignValueDelegate(AssignValue); } Is this de-registration necessary? The following is the code that I have written.. public partial class FrmSample : Form { Sample sampleObj; public FrmSample() { InitializeComponent(); this.Load += new EventHandler(FrmSample_Load); this.FormClosing += new FormClosingEventHandler(FrmSample_FormClosing); sampleObj = new Sample(); sampleObj.AssignValue = new Sample.AssignValueDelegate(AssignValue); } void FrmSample_FormClosing(object sender, FormClosingEventArgs e) { sampleObj.AssignValue -= new Sample.AssignValueDelegate(AssignValue); } void FrmSample_Load(object sender, EventArgs e) { sampleObj.LoadValue(); } void AssignValue(string value) { MessageBox.Show(value); } } class Sample { public delegate void AssignValueDelegate(string value); public AssignValueDelegate AssignValue; internal void LoadValue() { if (AssignValue != null) { AssignValue("This is a test message"); } } } Pls provide your feedback on whether this is right... Thanks, Ram

  • Windows 7 Create Folder in "Program Files" failing in C# code even thought I have admin rights!

    - by Shiva
    Hi, I am unable to create a file under "program files" folder on my Windows 7 64-bit machine in VS 2008 WPF C# code. The error I get on the following code myFile = File.Create(logFile); is the following. (this is the innerException stack trace). at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath) at System.IO.FileStream.Init(String path, FileMode mode, FileAccess access, Int32 rights, Boolean useRights, FileShare share, Int32 bufferSize, FileOptions options, SECURITY_ATTRIBUTES secAttrs, String msgPath, Boolean bFromProxy) at System.IO.FileStream..ctor(String path, FileMode mode, FileAccess access, FileShare share, Int32 bufferSize, FileOptions options) at System.IO.File.Create(String path) at MyFirm.MyPricingApp.UI.App.InitializeLogging() in C:\Projects\MyPricingApp\App.xaml.cs:line 150 at MyFirm.MyPricingApp.UI.App.Application_Startup(Object sender, StartupEventArgs e) in C:\Projects\MyPricingApp\App.xaml.cs:line 38 at System.Windows.Application.OnStartup(StartupEventArgs e) at System.Windows.Application.<.ctor>b__0(Object unused) at System.Windows.Threading.ExceptionWrapper.InternalRealCall(Delegate callback, Object args, Boolean isSingleParameter) at System.Windows.Threading.ExceptionWrapper.TryCatchWhen(Object source, Delegate callback, Object args, Boolean isSingleParameter, Delegate catchHandler) this seems like it has something to do with UAC in Windows 7, because why else would I get this since my user is already Admin on the machine ?! Also since the WinIOError has SECURITY_ATTRIBUTES, I am thinking this has something to do with a "new way" security is handled in Windows 7. I tried to browse to the "Program Files" folder, under which the log folder and file were to be created. I can create the folder by hand, but when i try to create the file, I get the similar "Access Denied" exception.

  • Moving UIScrollView in App

    - by jsetting32
    Currently, I am attempting to create the same effect as Yahoo! Weather's App where the vital day information is at the bottom of the page on the top of a UIScrollView, that's contained by a UIView. I am having a hard time thinking about how this is going to happen or how I should implement this. If the user taps on the top of the UIScrollView which is located near the bottom of the laoded UIView, and starts to scroll up (/), the UIScrollView's frame should be moved to the TOP of the current UIView's frame. So the UIScrollView's y-value should change to UIView's (self.view.frame.origin.y) if the user starts scrolling UP on the UIScrollView which is located on the UIView's y-pixel ~280. Here's what the UIViewController should look like in the beginning of loading the ViewController... Then once the user slides his finger from the bottom to the top of the screen... this should happen........ And when the user scrolls to the top of the UIScrollView with all the content within it... the view should go back to the start picture shown... How is this done? I was thinking several UIGestureRecognizer's and Instantiating the UIscrollview at the lower part of the UIView... _weatherView = [[UIScrollView alloc] initWithFrame:CGRectMake(self.view.frame.origin.x, self.view.frame.origin.y + 250, self.view.bounds.size.width, self.view.bounds.size.height - 44)]; _weatherView.contentSize = CGSizeMake(self.view.bounds.size.width, self.view.bounds.size.height * 4); _weatherView.backgroundColor = [UIColor clearColor]; [self.view addSubview:_weatherView]; The adding some UIGestureRecognizer delegate method.... But anyone have any ideas on the UIGestureRecognizer delegate method? And how it should be implemented? I can write the psuedo-code but I am having problems finding the delegate methods :P Thank you!!! ---- Break Time.... :)

  • Visitor Pattern can be replaced with Callback functions?

    - by getit
    Is there any significant benefit to using either technique? In case there are variations, the Visitor Pattern I mean is this: http://en.wikipedia.org/wiki/Visitor_pattern And below is an example of using a delegate to achieve the same effect (at least I think it is the same) Say there is a collection of nested elements: Schools contain Departments which contain Students Instead of using the Visitor pattern to perform something on each collection item, why not use a simple callback (Action delegate in C#) Say something like this class Department { List Students; } class School { List Departments; VisitStudents(Action<Student> actionDelegate) { foreach(var dep in this.Departments) { foreach(var stu in dep.Students) { actionDelegate(stu); } } } } School A = new School(); ...//populate collections A.Visit((student)=> { ...Do Something with student... }); *EDIT Example with delegate accepting multiple params Say I wanted to pass both the student and department, I could modify the Action definition like so: Action class School { List Departments; VisitStudents(Action<Student, Department> actionDelegate, Action<Department> d2) { foreach(var dep in this.Departments) { d2(dep); //This performs a different process. //Using Visitor pattern would avoid having to keep adding new delegates. //This looks like the main benefit so far foreach(var stu in dep.Students) { actionDelegate(stu, dep); } } } }

  • CoreData is saving model without the save: method being called

    - by chris
    I have a list of items with a plus button in the navigation bar that opens up a modal window containing a table of the models attributes, that displays a form when the table items are clicked (pretty standard form style). For some reason if I click the plus button to open the form to create a new model, then immediately click the done button, the person model is saved. The action linked to the done button does nothing but call on a delegate method notifying the personListViewController to close the window. The apple docs do state that the model is not saved after calling the insertNewObjectForEntityName: ... Simply creating a managed object does not cause it to be saved to a persistent store. The managed object context acts as a scratchpad. I am at a lost to why this is happening, but every time I click the done button I have a new blank item in the original tableView. I am using SDK v3.1.3 // PersonListViewController - open modal window - (void)addPerson { // Load the new form PersonNewViewController *newController = [[PersonNewViewController alloc] init]; newController.modalFormDelegate = self; [self presentModalViewController:newController animated:YES]; [newController release]; } // PersonFormViewController - (void)viewDidLoad { [super viewDidLoad]; if ( person == nil ) { MyAppDelegate *appDelegate = [[UIApplication sharedApplication] delegate]; self.person = [NSEntityDescription insertNewObjectForEntityForName:@"Person" inManagedObjectContext:appDelegate.managedObjectContext]; } ... UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone target:self action:@selector(done)]; self.navigationItem.rightBarButtonItem = doneButton; [doneButton release]; } - (IBAction) done { [self.modalFormDelegate didCancel]; } // delegate method in the original listViewController - (void) didCancel { [self dismissModalViewControllerAnimated:YES]; }

  • Starting an STA thread, but with parameters to the final function

    - by DRapp
    I'm a bit weak on how some delegates behave, such as passing a method as the parameter to be invoked. While trying to do some NUnit test scripts, I have something that I need to run many test with. Each of these tests requires a GUI created and thus the need for an STA thread. So, I have something like public class MyTest { // the Delegate "ThreadStart" is part of the System.Threading namespace and is defined as // public delegate void ThreadStart(); protected void Start_STA_Thread(ThreadStart whichMethod) { Thread thread = new Thread(whichMethod); thread.SetApartmentState(ApartmentState.STA); //Set the thread to STA thread.Start(); thread.Join(); } [Test] public void Test101() { // Since the thread issues an INVOKE of a method, I'm having it call the // corresponding "FromSTAThread" method, such as Start_STA_Thread( Test101FromSTAThread ); } protected void Test101FromSTAThread() { MySTA_RequiredClass oTmp = new MySTA_RequiredClass(); Assert.IsTrue( oTmp.DoSomething() ); } } This part all works fine... Now the next step. I now have a different set of tests that ALSO require an STA thread. However, each "thing" I need to do requires two parameters... both strings (for this case). How do I go about declaring proper delegate so I can pass in the method I need to invoke, AND the two string parameters in one shot... I may have 20+ tests to run with in this pattern and may have future of other similar tests with different parameter counts and types of parameters too. Thanks.

  • ThreadExceptionEventHandler and invoking delegates

    - by QmunkE
    If I assign a ThreadExceptionEventHandler to Application.ThreadException, why when I invoke a delegate method using a control on the main application thread are any exceptions thrown by that delegate not triggering the event handler? i.e. static void Main() { ... Application.ThreadException += new System.Threading.ThreadExceptionEventHandler(Application_ThreadException); Application.Run(new Form1()); } static void Application_ThreadException(object sender, System.Threading.ThreadExceptionEventArgs e) { Console.Error.Write("A thread exception occurred!"); } ... private void Form1_Load(object sender, EventArgs e) { Thread syncThread = new Thread(new ThreadStart(this.ThrowException)); syncThread.Start(); } private void ThrowException() { button1.Invoke(new MethodInvoker(delegate { // Not handled by ThreadExceptionEventHandler? throw new Exception(); })); } The context on this is that I have a background thread started from a form which is throwing an unhandled exception which terminates the application. I know this thread is going to be unreliable since it is network connectivity reliant and so subject to being terminated at any point, but I'm just interested as to why this scenario doesn't play out as I expect?

  • ViewController behaving oddly when pushed on the window

    - by ayazalavi
    I am using multiple controller during launch of an application in app delegate. One controller is for registration and the second controller is tabbar. tabbar was loading fine but when I pushed registration controller on window, contents went up by 20 units and I have good white blank screen at bottom. Therefore I recreated frame of my registration view controller in its viewdidload method and slided it 20 units down. The code is self.view.frame = CGRectMake(0, 20, self.view.frame.size.width, self.view.frame.size.height); and code in my app delegate for launch application was - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { if (![self accountExists]) { //code if account does not exists on iphone app database self.registerAccount = [[registerViewController alloc] initWithNibName:@"registerViewController" bundle:nil]; [window addSubview:registerAccount.view]; } else if([self autoLoginForAnyAccount]){ //code for autologin to app } else { self.tabBarController.selectedIndex = 1; self.tabBarController.delegate = self; [window addSubview:tabBarController.view]; } [window makeKeyAndVisible]; return YES; } if anyone knows why there is a white space at bottom when registration controller is pushed then please share it with me.

  • Error with custom Class definition in protocol

    - by Greg
    I'm trying to set up a custom delegate protocol and am getting a strange error that I don't understand. I wonder if someone could point out what I'm doing wrong here (I'm still new to Ob-C and protocol use)... The situation is that I've built my own URLLoader class to manage loading and parsing data from the internet. I'm now trying to set up a protocol for delegates to implement that will respond to the URLLoader's events. So, below is my protocol... #import <UIKit/UIKit.h> #import "URLLoader.h" /** * Protocol for delegates that will respond to a load. */ @protocol URLLoadResponder <NSObject> - (void)loadDidComplete:(URLLoader *)loader; - (void)loadDidFail:(URLLoader *)loader withError:(NSString *)error; @end However, I'm getting the following error for both method signatures: Expected ')' before 'URLLoader' I feel like I must be overlooking something small and silly. Any help folks could offer would be greatly appreciated! Whoops ... it was pointed out that I should include URLLoader.h. Here it is: #import <Foundation/Foundation.h> #import "URLLoadResponder.h" /** * URLLoader inferface. */ @interface URLLoader : NSObject { NSString *name; NSString *loadedData; NSMutableData *responseData; NSObject *delegate; BOOL _isLoaded; } @property (nonatomic, retain) NSString *name; @property (nonatomic, retain) NSString *loadedData; @property (nonatomic, retain) NSObject *delegate; - (void)loadFromURL:(NSString *)url; - (void)addCompleteListener:(id)observer selector:(SEL)sel; - (void)removeCompleteListener:(id)observer; - (void)parseLoadedData:(NSString *)data; - (void)complete; - (void)close; - (BOOL)isLoaded; + (NSURL *)makeUrlWithString:(NSString *)url; + (URLLoader *)initWithName:(NSString *)name; @end

  • Are there any shortcuts/easier(VB) style way for raising events in C#?

    - by Eric
    Example in VB I have a worker class Public Class worker Public Event EventNumber1(ByVal messages As Dictionary(Of Integer, String)) Public Event EventNumber2(ByVal message As String) Public Sub CallEventNumber1() Dim dict As New Dictionary(Of Integer, String) dict.Add(1, "EventNumber1 First message") dict.Add(2, "EventNumber1 Second message") RaiseEvent EventNumber1(dict) End Sub Public Sub CallEventNumber2() RaiseEvent EventNumber2("I am an EventNumber2 Message") End Sub End Class and wire them up in another class with AddHandler _worker.EventNumber1, AddressOf EventNumber1Handler AddHandler _worker.EventNumber2, AddressOf EventNumber2Handler and in C# the worker class class Worker { public delegate void EventNumber1Handler(Dictionary<int, string> messages); public delegate void EventNumber2Handler(string message); public event EventNumber1Handler EventNumber1; public event EventNumber2Handler EventNumber2; public void CallEventNumber1() { Dictionary<int, string> dict = new Dictionary<int, string>(); dict.Add(1, "EventNumber1 First message"); dict.Add(2, "EventNumber1 Second message"); if (EventNumber1 != null) EventNumber1(dict); } public void CallEventNumber2() { if (EventNumber2 != null) EventNumber2("I am an EventNumber2 Message"); } } and wire that up with worker.EventNumber1 += new Worker.EventNumber1Handler(worker_EventNumber1); worker.EventNumber2 += new Worker.EventNumber2Handler(worker_EventNumber2); So I guess my question is do I always need to add the delegate along with the event in c#? Is there any new syntax for c# 3.0/4.0? Regards _Eric

  • How to check if a thread is busy in C#?

    - by Sam
    I have a Windows Forms UI running on a thread, Thread1. I have another thread, Thread2, that gets tons of data via external events that needs to update the Windows UI. (It actually updates multiple UI threads.) I have a third thread, Thread3, that I use as a buffer thread between Thread1 and Thread2 so that Thread2 can continue to update other threads (via the same method). My buffer thread, Thread3, looks like this: public class ThreadBuffer { public ThreadBuffer(frmUI form, CustomArgs e) { form.Invoke((MethodInvoker)delegate { form.UpdateUI(e); }); } } What I would like to do is for my ThreadBuffer to check whether my form is currently busy doing previous updates. If it is, I'd like for it to wait until it frees up and then invoke the UpdateUI(e). I was thinking about either: a) //PseudoCode while(form==busy) { // Do nothing; } form.Invoke((MethodInvoker)delegate { form.UpdateUI(e); }); How would I check the form==busy? Also, I am not sure that this is a good approach. b) Create an event in form1 that will notify the ThreadBuffer that it is ready to process. // psuedocode List<CustomArgs> elist = new List<CustomArgs>(); public ThreadBuffer(frmUI form, CustomArgs e) { from.OnFreedUp += from_OnFreedUp(); elist.Add(e); } private form_OnFreedUp() { if (elist.count == 0) return; form.Invoke((MethodInvoker)delegate { form.UpdateUI(elist[0]); }); elist.Remove(elist[0]); } In this case, how would I write an event that will notify that the form is free? and c) an other ideas?

  • Viewpoint gem and Exchange resource account

    Hi- I'm trying my hand at using the Viewpoint gem (by zenchild @ github) as the base for a meeting scheduling system. It's great at reading calendar information from regular Exchange 2007 accounts, but I got stuck trying to change the SOAP request header to allow me to read resource accounts as a delegate. I came across http://blogs.msdn.com/b/mstehle/archive/2009/06/16/exchange-api-team-blog-exchange-impersonation-vs-delegate-access.aspx and it seems to be what I need, and I have the feeling I'm on the edge of getting it working, but I'm just not quite there yet as a ruby programmer. Any help would be appreciated... Thanks!

  • Broken Multithreading With Core Data

    - by spamguy
    This is a better-focused version of an earlier question that touches upon an entirely different subject from before. I am working on a Cocoa Core Data application with multiple threads. There is a Song and Artist; every Song has an Artist relation. There is a delegate code file not cited here; it more or less looks like the template XCode generates. I am far better working with the former technology than the latter, and any multithreading capability came from a Core Data template. When I'm doing all my ManagedObjectContext work in one method, I am fine. When I put fetch-or-insert-then-return-object work into a separate method, the application halts (but does not crash) at the new method's return statement, seen below. The new method even gets its own MOC to be safe, and it has not helped any. The result is one addition to Song and a halt after generating an Artist. I get no errors or exceptions, and I don't know why. I've debugged out the wazoo. My theory is that any errors occurring are in another thread, and the one I'm watching is waiting on something forever. What did I do wrong with getArtistObject: , and how can I fix it? Thanks. - (void)main { NSInteger songCount = 1; NSManagedObjectContext *moc = [[NSManagedObjectContext alloc] init]; [moc setPersistentStoreCoordinator:[[self delegate] persistentStoreCoordinator]]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(contextDidSave:) name:NSManagedObjectContextDidSaveNotification object:moc]; /* songDict generated here */ for (id key in songDict) { NSManagedObject *song = [NSEntityDescription insertNewObjectForEntityForName:@"Song" inManagedObjectContext:moc]; [song setValue:[songDictItem objectForKey:@"Name"] forKey:@"title"]; [song setValue:[self getArtistObject:(NSString *) [songDictItem objectForKey:@"Artist"]] forKey:@"artist"]; [songDictItem release]; songCount++; } NSError *error; if (![moc save:&error]) [NSApp presentError:error]; [[NSNotificationCenter defaultCenter] removeObserver:self name:NSManagedObjectContextDidSaveNotification object:moc]; [moc release], moc = nil; [[self delegate] importDone]; } - (NSManagedObject*) getArtistObject:(NSString*)theArtist { NSError *error = nil; NSManagedObjectContext *moc = [[NSManagedObjectContext alloc] init]; [moc setPersistentStoreCoordinator:[[self delegate] persistentStoreCoordinator]]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(contextDidSave:) name:NSManagedObjectContextDidSaveNotification object:moc]; NSFetchRequest *fetch = [[[NSFetchRequest alloc] init] autorelease]; NSEntityDescription *entityDescription = [NSEntityDescription entityForName:@"Artist" inManagedObjectContext:moc]; [fetch setEntity:entityDescription]; // object to be returned NSManagedObject *artistObject = [[NSManagedObject alloc] initWithEntity:entityDescription insertIntoManagedObjectContext:moc]; // set predicate (artist name) NSPredicate *pred = [NSPredicate predicateWithFormat:[NSString stringWithFormat:@"name = \"%@\"", theArtist]]; [fetch setPredicate:pred]; NSArray *response = [moc executeFetchRequest:fetch error:&error]; if (error) [NSApp presentError:error]; if ([response count] == 0) // empty resultset --> no artists with this name { [artistObject setValue:theArtist forKey:@"name"]; NSLog(@"%@ not found.

  • TableView doesnt show any Data(CoreData) - App crashe

    - by brush51
    Hey @all, i cant read my data from my database. I have an app with a tabbarcontroller. in the first tab the iphone camera takes a picture from a barcode and send the result to another view (CameraReturnDetailViewController). In CameraReturnDetailViewController is the savebutton, and here is the code from this save button: - (IBAction)saveAndQuitScan:(id) sender { XLog(@"saveAndQuitScan button wurde geklickt!"); ProjectQRCodeAppDelegate *appDelegate = [[UIApplication sharedApplication]delegate]; NSManagedObjectContext *context = [appDelegate managedObjectContext]; NSManagedObject *newData; newData = [NSEntityDescription insertNewObjectForEntityForName:@"BarcodeDaten" inManagedObjectContext:context]; [newData setValue:dataLabel.text forKey:@"Barcode_CD"]; NSError *error; [context save:&error]; //Aktuelle ansicht (self) animiert verlassen [self dismissModalViewControllerAnimated:YES]; // Nachdem die ansicht verlassen wurde, // auf das zweite Tab wechseln(scanverlauf) /** TO DO - Funktioniert noch nicht **/ [self.tabBarController setSelectedIndex:1]; } Now, my aim is to show the taba in the second tab, in a TableView (ScansViewController): - (void)viewDidLoad { [super viewDidLoad]; if (managedObjectContext_ == nil) { managedObjectContext_ = [(ProjectQRCodeAppDelegate *)[[UIApplication sharedApplication]delegate] managedObjectContext]; NSLog(@"After managedObjectContext: %@", managedObjectContext_); } myTableView = [[UITableView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame] style:UITableViewStylePlain]; myTableView.delegate = self; myTableView.dataSource = self; myTableView.autoresizesSubviews = YES; self.navigationItem.title = @"Code Liste"; self.view = myTableView; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return [itemsList count]; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease]; } return cell; } - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 1; } - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { NSString *selectDay = [NSString stringWithFormat:@"%d", indexPath.row]; TableDetailViewController *fvController = [[TableDetailViewController alloc] initWithNibName:@"TableDetailViewController" bundle:[NSBundle mainBundle]]; fvController.selectDay = selectDay; [self.navigationController pushViewController:fvController animated:YES]; [fvController release]; fvController = nil; } - (void) configureCell:(UITableViewCell *)cell atIndexPath:(NSIndexPath *)indexPath { NSManagedObject *managedObject = [self.fetchedResultsController objectAtIndexPath:indexPath]; cell.textLabel.text = [[managedObject valueForKey:@"Barcode_CD"] description]; } - (NSFetchedResultsController *) fetchedResultsController { if (fetchedResultsController_ !=nil) { return fetchedResultsController_; } NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"BarcodeDaten" inManagedObjectContext:self.managedObjectContext]; [fetchRequest setEntity:entity]; [fetchRequest setFetchBatchSize:20]; NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"Barcode_CD" ascending:NO]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:sortDescriptor, nil]; [fetchRequest setSortDescriptors:sortDescriptors]; NSFetchedResultsController *aFetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:fetchRequest managedObjectContext:self.managedObjectContext sectionNameKeyPath:nil cacheName:@"Root"]; aFetchedResultsController.delegate = self; self.fetchedResultsController = aFetchedResultsController; [aFetchedResultsController release]; [fetchRequest release]; [sortDescriptor release]; [sortDescriptors release]; NSError *error = nil; if (![fetchedResultsController_ performFetch:&error]) { XLog(@"Error: %@, %@", error, [error userInfo]); abort(); } return fetchedResultsController_; } At first i get this error when i choosed the second tab(ScansViewController): " Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '+entityForName: could not locate an NSManagedObjectModel for entity name 'BarcodeDaten'' " The Name is correct but i dont understand my mistake. No data is showed in the Tableview, why? Have I missed something..? Or something wrong? Thanks for help, brush51

  • (iOS) UI Automation AlertPrompt button/textField accessiblity

    - by lipd
    I'm having a bit of trouble with UI Automation (the built in to iOS tool) when it comes to alertView. First off, I'm not sure where I can set the accessibilityLabel and such for the buttons that are on the alertView. Secondly, although I am not getting an error, I can't get my textField to actually set the value of the textField to something. I'll put up my code for the alertView and the javaScript I am using for UI Automation. UIATarget.onAlert = function onAlert(alert) { // Log alerts and bail, unless it's the one we want var title = alert.name(); UIALogger.logMessage("Alert with title '" + title + "' encountered!"); alert.logElementTree(); if (title == "AlertPrompt") { UIALogger.logMessage(alert.textFields().length + ''); target.delay(1); alert.textFields()["AlertText"].setValue("AutoTest"); target.delay(1); return true; // Override default handler } else return false; } var target = UIATarget.localTarget(); var application = target.frontMostApp(); var mainWindow = application.mainWindow(); mainWindow.logElementTree(); //target.delay(1); //mainWindow.logElementTree(); //target.delay(1); var tableView = mainWindow.tableViews()[0]; var button = tableView.buttons(); //UIALogger.logMessage("Num buttons: " + button.length); //UIALogger.logMessage("num Table views: " + mainWindow.tableViews().length); //UIALogger.logMessage("Number of cells: " + tableView.cells().length); /*for (var currentCellIndex = 0; currentCellIndex < tableView.cells().length; currentCellIndex++) { var currentCell = tableView.cells()[currentCellIndex]; UIALogger.logStart("Testing table option: " + currentCell.name()); tableView.scrollToElementWithName(currentCell.name()); target.delay(1); currentCell.tap();// Go down a level target.delay(1); UIATarget.localTarget().captureScreenWithName(currentCell.name()); //mainWindow.navigationBar().leftButton().tap(); // Go back target.delay(1); UIALogger.logPass("Testing table option " + currentCell.name()); }*/ UIALogger.logStart("Testing add item"); target.delay(1); mainWindow.navigationBar().buttons()["addButton"].tap(); target.delay(1); if(tableView.cells().length == 5) UIALogger.logPass("Successfully added item to table"); else UIALogger.logFail("FAIL: didn't add item to table"); Here's what I'm using for the alertView #import "AlertPrompt.h" @implementation AlertPrompt @synthesize textField; @synthesize enteredText; - (id)initWithTitle:(NSString *)title message:(NSString *)message delegate:(id)delegate cancelButtonTitle:(NSString *)cancelButtonTitle okButtonTitle:(NSString *)okayButtonTitle withOrientation:(UIInterfaceOrientation) orientation { if ((self == [super initWithTitle:title message:message delegate:delegate cancelButtonTitle:cancelButtonTitle otherButtonTitles:okayButtonTitle, nil])) { self.isAccessibilityElement = YES; self.accessibilityLabel = @"AlertPrompt"; UITextField *theTextField; if(orientation == UIInterfaceOrientationPortrait) theTextField = [[UITextField alloc] initWithFrame:CGRectMake(12.0, 45.0, 260.0, 25.0)]; else theTextField = [[UITextField alloc] initWithFrame:CGRectMake(12.0, 30.0, 260.0, 25.0)]; [theTextField setBackgroundColor:[UIColor whiteColor]]; [self addSubview:theTextField]; self.textField = theTextField; self.textField.isAccessibilityElement = YES; self.textField.accessibilityLabel = @"AlertText"; [theTextField release]; CGAffineTransform translate = CGAffineTransformMakeTranslation(0.0, 0.0); [self setTransform:translate]; } return self; } - (void)show { [textField becomeFirstResponder]; [super show]; } - (NSString *)enteredText { return [self.textField text]; } - (void)dealloc { //[textField release]; [super dealloc]; } @end Thanks for any help!
