  • UITextField with the lookup

    - by leon
    Hello, I would like to achive the same functinoanlity in the UUTextField control as Google search web site (which uses Ajax for this): as user start typing, list of suggestion searches is shown. Then more letteres you type, suggestion list changes. So imaging I have array of words: Apple Abc Aman As user types A, all thress suggesions are shown, if user type one more letter p, then Apple is suggested. How would I do something like this? Mail type of applicatins do it, when receipent name is typed in the To: edit control I guess I can use UITableView with the search, is it correct approach?

  • 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

  • As-You-Type-Searching with Core Data / NSFetchedResultsController

    - by Snej
    I implemented an as-you-type-searching (text search on single attribute) by fetching with performFetch: after each given character by the user. The performFetch: is running in a background thread to avoid keyboard freezes. But while typing many useless fetches are started. A NSOperationQueue might be an option, but I wonder if there are other approaches for this quite usual search behavior. What's best practice to notice when fetching is done and the table view is updated with the previous fetch to start a new fetch?

  • Drawing in iPad

    - by Manjunath
    Hi all, I am trying to draw custom shapes in iPad application. I am using UIBezierPath for drawing which is available for 3.2 onwards. My question is whether it is good to use this class or should I go to the core graphics? Is there any difference between uibezierpath and core graphics drawing related to performance?

  • Flash not interacting with Javascripts in browser inside my app

    - by Shivaprasad
    Hi , I have an application which embeds a xulrunner based browser. I have to load some flash content in it which talks to some javascripts to update the browser title. The flash content works fine when launched from Firefox but not inside my app. I tried a sample html file which has some javascripts and they work fine. It even works when I have the flash content on a server. It is only when I try to run js through flash present on my local machine that I see this problem. I guess it must have something to do with some security settings in xulrunner. Could somebody help me figure out what the problem might be? Thanks jbsp72

  • 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?

  • 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.

  • 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];

  • 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

  • Switch between multiple views while respecting orientation

    - by zoul
    Hello! I have an MVC application with a single model and several views (something like skins). I want the user to be able to switch the views and I can’t get it working with interface orientation. The most simple approach looks like this: - (void) switchToADifferentView: (UIView*) newView { // self is a descendant of UIViewController self.view = newView; } This does not work because the incoming view does not get rotated according to current orientation (until the next orientation change, test case). Is there a way to force the orientation on a view? It looks like the system is trying really hard to keep the interface controls for itself. (Or is it as simple as setting the right transform by hand?) I figured I’d better not switch the views directly and switch controllers instead. This makes sense, as it makes the initial code simpler. But how do I switch controllers that have no “navigation relation” between them? I guess I could use presentModalViewController:, but that seems like a hack. Same goes for navigation controller. If I exchange the controllers by hand, I get the wrong orientation again: - (void) switchToAController: (id) incoming { [currentController.view removeFromSuperview]; [window addSubview:incoming.view]; // does not respect current orientation } Now how the heck do I simply exchange the current controller for another one? Again, the controllers are something like “skins” operating above a shared model, so it really makes no sense to pretend that skin A is a “modal” dialog above skin B or that they’re a part of a navigation stack.

  • [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

  • Calculating File size before download

    - by sagar
    Ok ! Coming to the point directly. What I want to do is explained as follows. I have an url of MP3 file. ( for example Sound File ) Now, When user starts application. Download should start & for that I have implemented following methods. -(void)viewDidLoad { [super viewDidLoad]; NSURL *url=[NSURL URLWithString:@"http://xyz.pqr.com/abc.mp3"]; NSURLRequest *req=[NSURLRequest requestWithURL:url cachePolicy:NSURLCacheStorageNotAllowed timeoutInterval:120]; NSURLConnection *con=[[NSURLConnection alloc] initWithRequest:req delegate:self startImmediately:YES]; if(con){ myWebData=[[NSMutableData data] retain]; } else { // [MainHandler performSelector:@selector(targetSelector:) withObject:nil]; } } -(void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response{ NSLog(@"%@",@"connection established"); [myWebData setLength: 0]; } -(void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data { NSLog(@"%@",@"connection receiving data"); [myWebData appendData:data]; } -(void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error { NSLog(@"%@",@"connection failed"); [connection release]; // [AlertViewHandler showAlertWithErrorMessage:@"Sorry, there is no network connection. Please check your network and try again."]; // [self parserDidEndDocument:nil]; } -(void)connectionDidFinishLoading:(NSURLConnection *)connection { [connection release]; } Now, Above methods work perfectly for downloading. But missing points are as follows. I can not get the exact size which is going to be downloaded. ( means I want to know what is the size of file - which is going to be download )

  • Integrate openid4java to GWT Project

    Hi, I created an GWT project in eclipse. Now I tried to implement openId with using the openid4java library.

  • NSNumber >= 13 won't retain. Everything else will.

    - by jkap
    The code I'm currently working on requires adding an NSNumber object to an array. All of the NSNumbers with value 0-12 are added fine, but 13 onward causes a EXC_BAD_ACCESS. I turned on NSZombieEnabled and am now getting *** -[CFNumber retain]: message sent to deallocated instance 0x3c78420.

  • Will pool the connection help threading in sqlite (and how)?

    - by mamcx
    I currently use a singleton to acces my database (see related question) but now when try to add some background processing everything fall apart. I read the sqlite docs and found that sqlite could work thread-safe, but each thread must have their own db connection. I try using egodatabase that promise a sqlite wrapper with thread safety but is very buggy, so I return to my old FMDB library I start to see how use it in multi-thread way. Because I have all code with the idea of singleton, change everything will be expensive (and a lot of open/close connections could become slow), so I wonder if, as the sqlite docs hint, build a pooling for each connection will help. If is the case, how make it? How know wich connection get from the pool (because 2 threads can't share the connection)? I wonder if somebody already use sqlite in multu-threading with NSOperation or similar stuff, my searching only return "yeah, its possible" but let the details to my imagination...

  • 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]; }

  • UITableView Section Headers Drawing Above Front Subview

    - by hadronzoo
    I have a UITableView whose data have sections. I display an overlay view on top of tableView that dims it when searching: - (UIView *)blackOverlay { if (!blackOverlay) { blackOverlay = [[UIView alloc] initWithFrame:[self overlayFrame]]; blackOverlay.alpha = 0.75; blackOverlay.backgroundColor = UIColor.blackColor; [tableView insertSubview:blackOverlay aboveSubview:self.parentViewController.view]; } return blackOverlay; } This works perfectly as long as tableView does not contain sections. When tableView does contain sections and the tableView updates (such as when the view reappears after popping a view off of the navigation controller stack), the section headers are rendered above blackOverlay. This leaves tableView dimmed except for the section headers. I've tried calling [tableView bringSubviewToFront:self.blackOverlay] from within viewWillAppear:, but I get the same behavior. My current work-around is returning nil for tableView section headers while the overlay is present, but this leaves whitespace gaps in the overlaid tableView where the section headers were previously. How can I insure that tableView section headers are never drawn above blackOverlay? Or, is it possible to create a view in front of tableView from within a UITableViewController subclass that is not a subview of tableView?

  • Is there a way to disable calls to Runtime.checkRestricted on the GAE Java development server under Eclipse?

    - by Thomas Becker
    I'm one of those guys who step through their code a lot during development. Beginning with version 1.6.4 of the GAE Java development server, the server has been instrumented with calls to a function named Runtime.checkRestricted. This causes two inconveniences when I step through my code: 1) Whenever I step into a function, the debugger goes into the function Runtime.checkRestricted (for which there is no source code) at least once, often multiple times. 2) Whenever I step over a function call which has a large call tree underneath it, then it takes a very long time for the debugger to come back. (That's always a problem in the Eclipse Java debugger, but now it's really bad.) For me, all this causes a serious drain on productivity. Is there any way to disable this instrumentation, or to prevent the debugger from stepping into it? I am using Eclipse with the GAE plugin.
