  • How to add View Controller with Tab Bar interfaced View Controller

    - by TechFusion
    I have created Window based Tab Bar controller app, One Tab Bar of viewController has been interfaced with WebVIew ..I am looking to create another view once touch event happened in that WebView.. //TabBarViewController.m - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { TabMainView *mainView = [[TabMainView alloc] init]; mainView.hidesBottomBarWhenPushed = YES; [self.navigationController pushViewController: mainView animated:YES]; [mainView release]; } I have created MainView, which is UIViewController Subclass. //TabMainView.m - (void)loadView { CGRect frame = CGRectMake(0.0, 0.0, 480, 320); WebView = [[[UIWebView alloc] initWithFrame:frame] autorelease]; WebView.backgroundColor = [UIColor whiteColor]; WebView.scalesPageToFit = YES; WebView.autoresizingMask = (UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleTopMargin); WebView.autoresizesSubviews = YES; WebView.exclusiveTouch = YES; //self.WebView.UserInteractionEnabled = NO; WebView.clearsContextBeforeDrawing = YES; self.view = WebView; [WebView release]; } - (void)viewWillAppear:(BOOL)animated { [self.WebView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://www.apple.com"]]]; } Here when touch event happened then it is not passing control to TabMainView.m 's Viewload function although I am pushing it's view? TabBarView is also UIViewController subclass not a UINavigationController.

  • [CFArray release]: message sent to deallocated instance

    - by arielcamus
    Hi, I'm using the following method in my code: - (NSMutableArray *) newOrderedArray:(NSMutableArray *)array ByKey:(NSString *)key ascending:(BOOL)ascending { NSSortDescriptor *idDescriptor = [[NSSortDescriptor alloc] initWithKey:key ascending:ascending]; NSArray *sortDescriptors = [NSArray arrayWithObject:idDescriptor]; NSArray *orderArray = [array sortedArrayUsingDescriptors:sortDescriptors]; [idDescriptor release]; NSMutableArray *result = [NSMutableArray arrayWithArray:orderArray]; return result; } Is this a well-coded convenience method? As I think, it returns an autoreleased NSMutableArray. This method is called by another one: - (id) otherMethod { NSMutableArray *otherResult = [[[NSMutableArray alloc] initWithCapacity:[otherArray count]] autorelease]; // I add some stuff to otherResult and then... NSMutableArray *result = [dbUtils newOrderedArray:otherResult ByKey:@"objectId" ascending:NO]; return result; } This method (otherMethod) is called in some view controller where I want to store returned array and release it when deallocating the view controller. However, when [result retain] is called in this view controller (because I need it to be available and I can't allow it to be deallocated) I receive the following error: [CFArray release]: message sent to deallocated instance I've tried to log [result retainCount] just before calling retain and it print "1". I don't understand why an error is thrown when calling retain. Thank you, A

  • No method found compiler warning

    - by Magic Bullet Dave
    I have create a class from a string, check it is valid and then check if it responds to a particular method. If it does then I call the method. It all works fine, except I get an annoying compiler warning: "warning: no '-setCurrentID:' method found". Am I doing something wrong here? Is there anyway to tell the compiler all is ok and stop it reporting a warning? The here is the code: // Create an instance of the class id viewController = [[NSClassFromString(class) alloc] init]; // Check the class supports the methods to set the row and section if ([viewController respondsToSelector:@selector(setCurrentID:)]) { [viewController setCurrentID:itemID]; } // Push the view controller onto the tab bar stack [self.navigationController pushViewController:viewController animated:YES]; [viewController release]; Cheers Dave

  • Memory problem with basic UITableView when scrolling

    - by Sheehan Alam
    I have a very simple UITableView that has 3 sections, and 3 rows per section. #pragma mark - #pragma mark UITableView delegate methods - (NSInteger)tableView:(UITableView *)tblView numberOfRowsInSection:(NSInteger)section { return 3; } - (UITableViewCell *)tableView:(UITableView *)tblView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tblView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; } // Configure the cell... return cell; } - (NSInteger)numberOfSectionsInTableView:(UITableView *)tblView { if (tblView == self.tableView) { return 3; } else { return 1; } } Everything shows up fine, but as soon as I scroll my application crashes and my debugger tells me: * -[ProfileViewController tableView:cellForRowAtIndexPath:]: message sent to deallocated instance 0x5ae61b0 I'm not exactly sure what I am doing wrong.

  • Navigation Items in UITableViewController are not appearing?

    - by Sheehan Alam
    I am displaying a UITableViewController inside of a UITabBarController that is being presented modally: -(IBAction)arButtonClicked:(id)sender{ //this is a uitableviewcontroller ARViewController* arViewController = [[[ARViewController alloc] initWithNibName:@"ARViewController" bundle:nil]autorelease]; LeaderBoardTableViewController* lbViewController = [[[LeaderBoardTableViewController alloc] initWithNibName:@"LeaderBoardTableViewController" bundle:nil]autorelease]; lbViewController.title = @"Leaderboard"; arTabBarController = [[UITabBarController alloc] initWithNibName:nil bundle:nil]; arTabBarController.viewControllers = [NSArray arrayWithObjects:arViewController, lbViewController, nil]; arTabBarController.selectedViewController = arViewController; [self presentModalViewController:arTabBarController animated:YES]; } In my viewDidLoad for arViewController method I am setting the navigation items: - (void)viewDidLoad { [super viewDidLoad]; // Uncomment the following line to preserve selection between presentations. self.clearsSelectionOnViewWillAppear = NO; self.title = @"AR"; leaderBoardButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemOrganize target:self action:@selector(leaderBoardButtonClicked:)]; self.navigationItem.rightBarButtonItem = leaderBoardButton; } My navigation bar doesn't appear when it is inside of the UITabBarController, but when I push the view itself I am able to see it. What am I missing?

  • Can't resignFirstResponder with UITextView

    - by Calvin L
    I have a UITextView. I implemented a navigationBar UIBarButtonItem to respond to a touch and resign the firstResponder for my UITextView. But, when the selector method is called, the keyboard doesn't get dismissed. I checked the UITextView's responder status with isFirstResponder and it returns YES. I also checked it with canResignFirstResponder and the return value is NO. I must be missing something here...why is it returning NO? I get that I can override canResignFirstResponder by subclassing UITextView, but I'd like to avoid that if possible. Here's a code snippet: - (void) commentCancelButtonTouched:(id)sender { NSLog(@"Cancel button touched"); [self.navigationBar popNavigationItemAnimated: NO]; if ([self.textInput.textView canResignFirstResponder] == NO) { NSLog(@"I don't want to resign!"); } [self.textInput.textView resignFirstResponder]; }

  • UITableView, having problems changing accessory when selected

    - by zpasternack
    I'm using a UITableView to allow selection of one (of many) items. Similar to the UI when selecting a ringtone, I want the selected item to be checked, and the others not. I would like to have the cell selected when touched, then animated back to the normal color (again, like the ringtone selection UI). A UIViewController subclass is my table's delegate and datasource (not UITableViewController, because I also have a toolbar in there). I'm setting the accessoryType of the cells in cellForRowAtIndexPath:, and updating my model when cells are selected in didSelectRowAtIndexPath:. The only way I can think of to set the selected cell to checkmark (and clear the previous one) is to call [tableView reloadData] in didSelectRowAtIndexPath:. However, when I do this, the animating of the cell deselection is weird (a white box appears where the cell's label should be). If I don't call reloadData, of course, the accessoryType won't change, so the checkmarks won't appear. I suppose I could turn the animation off, but that seems lame. I also toyed with getting and altering the cells in didSelectRowAtIndexPath:, but that's a big pain. Any ideas? Abbreviated code follows... - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { UITableViewCell* aCell = [tableView dequeueReusableCellWithIdentifier:kImageCell]; if( aCell == nil ) { aCell = [[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:kImageCell]; } aCell.text = [imageNames objectAtIndex:[indexPath row]]; if( [indexPath row] == selectedImage ) { aCell.accessoryType = UITableViewCellAccessoryCheckmark; } else { aCell.accessoryType = UITableViewCellAccessoryNone; } return aCell; } - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { [tableView deselectRowAtIndexPath:indexPath animated:YES]; selectedImage = [indexPath row] [tableView reloadData]; }

  • Managing several hundred occurrences of NSLocalizedString

    - by Gordon Hughes
    My application has several hundred points of localisation, some of which can be reused many times. To prevent from hunting and pecking through code to find occurrences of a particular NSLocalizedString, I create a macro for each in a header file using the #define preprocessor directive. For example: #define kLocFirstString NSLocalizedString(@"Default Text", @"Comment") #define kLocSecondString NSLocalizedString(@"More Text", @"Another comment") ... When I want to refer to a particular string, I do so by its macro name. This method has been working nicely for me, but I'm concerned that such blatant abuse of #define is frowned upon. From the standpoint of "correctness", should I just inline each NSLocalizedString with the code, or is there another method (extern NSString *aString; perhaps?) that I can use to collect the declarations in one place?

  • UINavigationController + shouldAutoRotate + no subclassing

    - by ACBurk
    I have a navigation driven app. I need that app to rotate. The UINavigationController is the root controller/view in the window. I know (and have experienced why) it is a no-no to subclass UINavigationController. I know all i have to do is insert: - (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return YES; } into the UINavigationController and it will rotate fine. So my question is: how do I enable rotation on the root view controller (UINavigationController) WITHOUT subclassing it?

  • Core Data - How to check if a managed object's properties have been deallocated?

    - by georryan
    I've created a program that uses core data and it works beautifully. I've since attempted to move all my core data methods calls and fetch routines into a class that is self contained. My main program then instantiates that class and makes some basic method calls into that class, and the class then does all the core data stuff behind the scenes. What I'm running into, is that sometimes I'll find that when I grab a managed object from the context, I'll have a valid object, but its properties have been deallocated, and I'll cause a crash. I've played with the zombies and looked for memory leaks, and what I have gathered is it seems that the run loop is probably responsible for deallocating the memory, but I'm not sure. Is there a way to determine if that memory has been deallocated and force the core data to get it back if I need to access it? My managedObjectContext never gets deallocated, and the fetchedResultsController never does, either. I thought maybe I needed to use the [managedObjectContext refreshObject:mergeData:] method, or the [managedObjectContext setRetainsRegisteredObjects:] method. Although, I'm under the impression that last one may not be the best bet since it will be more memory intensive (from what I understand). These errors only popped up when I moved the core data calls into another class file, and they are random when they show up. Any insight would be appreciated. -Ryan

  • Nested factory methods in Objective-C

    - by StephenT
    What's the best way to handle memory management with nested factory methods, such as in the following example? @implementation MyClass + (MyClass *) SpecialCase1 { return [MyClass myClassWithArg:1]; } + (MyClass *) SpecialCase2 { return [MyClass myClassWithArg:2]; } + (MyClass *) myClassWithArg:(int)arg { MyClass *instance = [[[MyClass alloc] initWithArg:arg] autorelease]; return instance; } - (id) initWithArg:(int)arg { self = [super init]; if (nil != self) { self.arg = arg; } return self; } @end The problem here (I think) is that the autorelease pool is flushed before the SpecialCaseN methods return to their callers. Hence, the ultimate caller of SpecialCaseN can't rely on the result having been retained. (I get "[MyClass copyWithZone:]: unrecognized selector sent to instance 0x100110250" on trying to assign the result of [MyClass SpecialCase1] to a property on another object.) The reason for wanting the SpecialCaseN factory methods is that in my actual project, there are multiple parameters required to initialize the instance and I have a pre-defined list of "model" instances that I'd like to be able to create easily. I'm sure there's a better approach than this.

  • Issue while adding 'Cc' Field in 'TTMessageController' (Three 20)

    - by Deepika
    Hi All I am using the TTMessageController class for compose mail.There is only 'To' recepients Field in this class. I added the Cc Field in it. I have used this code: - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { if (self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]) { _fields = [[NSArray alloc] initWithObjects: [[[TTMessageRecipientField alloc] initWithTitle: TTLocalizedString(@"To:", @"") required: YES] autorelease], [[[TTMessageRecipientField alloc] initWithTitle: TTLocalizedString(@"Cc:", @"") required: YES] autorelease], [[[TTMessageSubjectField alloc] initWithTitle: TTLocalizedString(@"Subject:", @"") required: NO] autorelease], nil]; self.title = TTLocalizedString(@"New Message", @""); self.navigationItem.leftBarButtonItem = [[[UIBarButtonItem alloc] initWithTitle: TTLocalizedString(@"Cancel", @"") style: UIBarButtonItemStyleBordered target: self action: @selector(cancel)] autorelease]; self.navigationItem.rightBarButtonItem = [[[UIBarButtonItem alloc] initWithTitle: TTLocalizedString(@"Send", @"") style: UIBarButtonItemStyleDone target: self action: @selector(send)] autorelease]; self.navigationItem.rightBarButtonItem.enabled = NO; } return self; } When I type anything in 'To' or 'Cc' field , two lists are appearing as search result:- One for 'To' field and second for 'Cc' Field. I want to show only one list according to 'To' or 'Cc' Field. Please suggest me any idea how can I resolve it or some other better way to implement my requirements? Thanks Deepika

  • Save downloaded content when in app purchase is complete

    - by jakob
    Hello experts! I have created an app which allows users to buy non-consumable content. The retrieving-ids-payment-process works like a charm. What i can't really figure out is how my content should be saved into the phone. The existing structure is that I have all my current content in Resources/packages/. For every package there is an matching entry in a package.plist. When the purchase is complete it is time to download the content from the server. What i retrieve from the server is a zip file with the new package that I have bought. My observer will call a method named provideContent: -(void) provideContent: (NSString*) productIdentifier { In here I will call my server and download the package } What i need from you guys is some sort of step by step walkthrough or tutorial of how, when the zip is retrieved(is zip allowed?), unpack this zip and add it to my current package structure. Thank you in advance

  • UIAlertView crashing on undocumented method

    - by morticae
    Our app has been crashing with a frequency of roughly 1 in 1,500 launches due to a bug that is proving elusive. The relevant portion of the stack trace is included. It's being fired as a callback so I have no reference for where it's occurring in my own code. It looks like what's going on is there is a UIViewAnimationState object that is calling UIAlertView's private method (_popoutAnimationDidStop:finished:). Only problem is, it appears the UIAlertView has been dealloced by this point. I don't do anything weird with alert views. I throw them up, and I wait for user input. They are all shown before being released. Anyone encountered this? At this point, I'm leaning toward it being an Apple bug.

  • View controllers inside tab bar controller not auto-rotating

    - by Padawan
    In an iPad app, I have five regular view controllers (not navigation controllers or anything like that) inside a tab bar controller. The tab bar controller is just a plain UITabBarController declared in the app delegate. All the view controllers return YES in the shouldAutorotateToInterfaceOrientation method. On both the simulator and device, on rotation, the tab bar rotates properly but the currently selected view controller (call it A) does not. If I switch to another view controller B and then back to A (without rotating the device again), A appears correctly rotated. This happens with any of the five view controllers Why doesn't the currently selected view controller rotate and how do I fix it? Thanks.

  • Why doesen't it work to write this NSMutableArray to a plist?

    - by Emil
    edited. Hey, I am trying to write an NSMutableArray to a plist. The compiler does not show any errors, but it does not write to the plist anyway. I have tried this on a real device too, not just the Simulator. Basically, what this code does, is that when you click the accessoryView of a UITableViewCell, it gets the indexPath pressed, edits an NSMutableArray and tries to write that NSMutableArray to a plist. It then reloads the arrays mentioned (from multiple plists) and reloads the data in a UITableView from the arrays. Code: NSIndexPath *indexPath = [table indexPathForRowAtPoint:[[[event touchesForView:sender] anyObject] locationInView:table]]; [arrayFav removeObjectAtIndex:[arrayFav indexOfObject:[NSNumber numberWithInt:[[arraySub objectAtIndex:indexPath.row] intValue]]]]; NSString *rootPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0]; NSString *plistPath = [rootPath stringByAppendingPathComponent:@"arrayFav.plist"]; NSLog(@"%@ - %@", rootPath, plistPath); [arrayFav writeToFile:plistPath atomically:YES]; // Reloads data into the arrays [self loadDataFromPlists]; // Reloads data in tableView from arrays [tableFarts reloadData];

  • Pushing to a UITable inside a UIView from a UITableview

    I can firgure out how to push a UIView from a Tableview and have the "child" details appear. Here is the view I'm trying to load: Here is the code that checks for children and either pushes a itemDetail.xib or an additional UITable, I want to use the above .xib but load the correct contents "tableDataSource" into the UItable: - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { //Get the dictionary of the selected data source. NSDictionary *dictionary = [self.tableDataSource objectAtIndex:indexPath.row]; //Get the children of the present item.

I see lots of stuff on this but can't find the correct push instructions.

  • Transform/redraw view after pinch zoom on x-axis

    - by Jonathan
    My setup. UIScrollView (scrollView) - UIView (contentView) - UIView (subView) I have managed to do so I can zoom contentView only on the x-axis. The problem is that subView is containing a graph. When contentView is zoomed and transformed the graph gets unsharp and distorded since the scaling only effect the x-axis. What I need help with is to somehow redraw the contentView after I'm done with the zooming without distorting the graph. Is it possible to transform the contentView so that the graph stays sharp even if you only zoom in the x-axis or redraw the content in the zoomed/stretched view somehow? I have tried the solution in this thread link but haven't succeeded to get it running.

  • Reading email address from contacts fails with weird memory issue

    - by CapsicumDreams
    Hi all, I'm stumped. I'm trying to get a list of all the email address a person has. I'm using the ABPeoplePickerNavigationController to select the person, which all seems fine. I'm setting my ABRecordRef personDealingWith; from the person argument to - (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier { and everything seems fine up till this point. The first time the following code executes, all is well. When subsequently run, I can get issues. First, the code: // following line seems to make the difference (issue 1) // NSLog(@"%d", ABMultiValueGetCount(ABRecordCopyValue(personDealingWith, kABPersonEmailProperty))); // construct array of emails ABMultiValueRef multi = ABRecordCopyValue(personDealingWith, kABPersonEmailProperty); CFIndex emailCount = ABMultiValueGetCount(multi); if (emailCount 0) { // collect all emails in array for (CFIndex i = 0; i < emailCount; i++) { CFStringRef emailRef = ABMultiValueCopyValueAtIndex(multi, i); [emailArray addObject:(NSString *)emailRef]; CFRelease(emailRef); } } // following line also matters (issue 2) CFRelease(multi); If compiled as written, the are no errors or static analysis problems. This crashes with a *** -[Not A Type retain]: message sent to deallocated instance 0x4e9dc60 error. But wait, there's more! I can fix it in either of two ways. Firstly, I can uncomment the NSLog at the top of the function. I get a leak from the NSLog's ABRecordCopyValue every time through, but the code seems to run fine. Also, I can comment out the CFRelease(multi); at the end, which does exactly the same thing. Static compilation errors, but running code. So without a leak, this function crashes. To prevent a crash, I need to haemorrhage memory. Neither is a great solution. Can anyone point out what's going on?
