  • Cocos 2D v1.0.1 : Crash at changing CCMenuItemImage normal image

    - by Max
    I retrieve a crash log file, which, after XCode analysis on my archive show the problematic line of code : Date/Time: 2012-12-08 23:48:08.930 +0100 OS Version: iPhone OS 5.1.1 (9B206) Report Version: 104 Exception Type: EXC_CRASH (SIGABRT) Exception Codes: 0x00000000, 0x00000000 Crashed Thread: 0 Last Exception Backtrace: 0 CoreFoundation 0x31a4088f __exceptionPreprocess + 163 1 libobjc.A.dylib 0x3188b259 objc_exception_throw + 33 2 CoreFoundation 0x31a40789 +[NSException raise:format:] + 1 3 Foundation 0x374c73a3 -[NSAssertionHandler handleFailureInMethod:object:file:lineNumber:description:] + 91 4 Killer 0x0017ed35 -[CCSprite initWithFile:] (CCSprite.m:201) 5 Killer 0x0017e419 +[CCSprite spriteWithFile:] (CCSprite.m:93) 6 Killer 0x00123101 -[Player makeZombie] (Player.m:1363) 7 Killer 0x00105a51 -[PlayScene endOfKilling:] (PlayScene.m:1438) Which clearly indicates the second of the two following lines is crashing: NSLog(@"images %@ %@",self.zombieImage,self.zombieImageDown); [self.characterSprite setNormalImage:[CCSprite spriteWithFile:self.zombieImage]]; I know that the crash seem to happend when the user is touching the corresponding CCMeanuItemImage, is there a problem if the user is touching it, while we change the normal et selected images of it ? Is this the right manner to change its image (i do it several times during the game) ? Thanks for your ideas

  • Does tableViewController behave incorrectly when hosted by a popoverController?

    - by dugla
    I have made countless test examples of a tableViewController hosted by a popoverController and I have come to the following conclusion: It does not appear possible to pre-select a tableView cell. It is possible to do pre-selection when a tableViewController is hosted by a splitviewController. I am using the exact same tableViewController code. Here is the relevant tableViewController view lifecycle method that is misbehaving: static BOOL firstTime = YES; - (void)viewDidAppear:(BOOL)animated { NSLog(@"Root ViewController - view Did Appear"); [super viewDidAppear:animated]; if (firstTime == YES) { firstTime = NO; NSIndexPath *preselectedCell = [NSIndexPath indexPathForRow:5 inSection:0]; [self.tableView selectRowAtIndexPath:preselectedCell animated:NO scrollPosition:UITableViewScrollPositionTop]; detailViewController.detailItem = [NSString stringWithFormat:@"Row %d", preselectedCell.row]; } // if (firstTime == YES) } The above code correctly preselects a tableView cell the first time the tableView is unfurled in the splitViewController case (device in portrait mode). Can someone please, please, explain what I am doing wrong. I am completely stumped. Thanks, Doug

  • What alternatives do I have for source control and does GIT does that?

    - by RubberDuck
    I work as a freelancer programmer for some clients and also create apps for myself. When I work for myself, obviously I work alone. I generally don't work in a linear way. My big problems today are: I have a lot of apps that use the same classes I have developed; In the past, I put all these common classes on a directory outside all projects and included them on my apps using absolute paths, but this method sucks because by accident (if you forget) you may change a path or the disk and all projects are broken. Then I decided to copy those classes to my projects every time. Because the majority of these classes do not change frequently, I am relatively ok, but when they change, I am in hell; When I change one of these classes I have to propagate the changes to all other apps using copies of them. I have also tried to create frameworks but thanks to Apple, I cannot create frameworks for iOS and have to create libraries and bundles and create a nightmare of paths from one to the other and to the project to make that sh!t works. So, I am done with frameworks/libraries on Xcode until Xcode is a decent IDE. So, I see I need something better to manage my source code. What I need is this (I never used GIT on Xcode. I have read Apple docs but I still have these points): does git locally on Xcode allows me to deal with assets or just code? Can I have the equivalent of a "framework" (code + assets) managed by git locally? Can an entire xcodeproj be managed as a unity? I mean, Suppose I have a xcodeproj created and want GIT to manage it. How do I enable git on a project that was created without it and start designating files for management. (I have enabled git on Xcode's preferences, but all source control menu is grayed out). Is git the best option? Do I have another? Remember that my main condition is that the files should stay on the local computer. Please save me (I am a bit dramatic today). Thanks.

  • iOS Development: Does the GameKit SDK allow you to retrieve achievements by players other than the local player?

    - by BeachRunnerJoe
    Hello. I'm building a game that uses Game Center to connect players and manage leaderboards and achievements. I see that you can retrieve leaderboard details for any player, but can you do the same with achievements? When the user finishes a match with an opponent, I'd like to give the user the option to view the opponents profile, including leaderboard scores and completed achievements. I haven't found anything in the docs that shows me how to retrieve achievement details for players other than the local player, am I missing it or is this currently not supported? Thanks so much for your help!

  • ivar is inside two blocks

    - by Desperate Developer
    I have an ivar like this declared on interface: BOOL controllerOK; I have to use this ivar inside a block that resides itself in a block. Something like myBlockl = ^(){ [self presentViewController:controller animated:YES completion:^(){ if (controllerOK) [self doStuff]; }]; }; If I try to do that, I see an error capturing self strongly in this block is likely to lead to a retain cycle for the if (controllerOK) line. This does not appear to be one of those blocks problems that you create another variable using __unsafe_unretained before the block starts. First because this instruction cannot be used with a BOOL and second because the ivar controllerOK has to be tested on runtime inside the block. Another problem is that the block itself is declared on the interface, so it will be used outside the context where it is being created. How do I solve that?

  • PDF search on the iPhone

    - by pt2ph8
    After two days trying to read annotations from a PDF using Quartz, I've managed to do it and posted my code. Now I'd like to do the same for another frequently asked question: searching PDF documents with Quartz. Same situation as before, this question has been asked many times with almost no practical answers. So I need some pointers first, as I still haven't implemented this myself. What I tried: I tried using CGPDFScannerScan handling the TJ and Tj operators - returns the right text on some PDF, whereas on other documents it returns mostly random letters. Maybe it's related to text encoding? Someone pointed out that text blocks (marked by BT/ET operators) should be handled instead, but I still haven't managed to do so. Anyone managed to extract text from any PDF? After that, searching should be easy by storing all the text in a NSMutableString and using rangeOfString (if there's a better way please let me know). But then how to highlight the result? I know there are a few operators to find the glyph sizes, so I could calculate the resulting rect based on those values, but I've been reading the spec for hours... it's a bloated mess and I'm going insane. Anyone with a practical explanation? Thanks.

  • UIView capturing all events

    - by Josh P.
    I have a UIView that uses several UIGestureRecognizers and this view again has at least one child view that contains a MPMoviePlayerController. When a touch event occurs over the movie player, the main view seems to 'eat' all the events, leaving the media player idle. How can I make sure that the events are delivered correctly to the player?

  • iphone/ipad with 2 side by side tables

    - by jesse001
    I want to create a view with 2 tables side by side, where selecting the row on 1 table effects the content of the other and vice versa (not parent child). My problem is how to send the request. I started with a utility app using core data, and added 2 table view controllers. I added these to the main view nib and moved the tables to the view. One table controls a list from Core Data, then on selecting a row I want it to move to the other table which is based on a mutable array. On didselectrow I want to tell the other table to update, however I can only find samples that are parent/child so involves initializing. Does anyone know of a way to do this for an active view? Thanks heaps for your help.

  • iphone view controller class - how to

    - by Brodie4598
    Hello - I need to create my own UIView class and it is not something I have had to do. I created the class, then laid out the small view in IB (it's just a few labels that i will later need to add data to ). but now im stuck on how to actually put an instance of it in my main view. Can someone point me in the direction of a good tutorial? The closest thing I have done to this is creating a custom tableViewCell. DataTagViewController *dataTag = [[DataTagViewController alloc]init]; [theMap addSubView: dataTag];

  • Correct way to switch between UIView with ARC. My way leads to memory leaks :( (iOS)

    - by Andrei Golubev
    i use xcode 4.4 with ARC on.. I have dynamically created UIViews in the ViewController.m: UIView*myviews[10]; Then in the - (void)viewDidLoad function i fill each of it with pictures i need myviews[viewIndex] = [[UIView alloc]initWithFrame:myrec]; UIImage *testImg; UIImageView * testImgView; testImg = [UIImage imageNamed:[NSString stringWithFormat:@"imgarray%d.png", viewIndex]; testImgView.image = testImg; viewindex++; So all seems to be fine, when i want to jump from one view to another i do with two buttons next: [self.view addSubview:views[viewIndex]]; CATransition *animation = [CATransition animation]; [animation setDelegate:self]; [animation setDuration:1.0f]; [animation setType:@"rippleEffect"]; [animation setSubtype:kCATransitionFromTop]; //[animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]]; [self.view.layer addAnimation:animation forKey:@"transitionViewAnimation"]; Nothing seems to be bad, but the memory consumption grows with huge speed when i switch between views.. and then i get low memory warning or sometimes application will just crash. I have tried to use UIViewController array and was switching between the controllers: nothing changes, the memory low warning is what i end up with.. Maybe i need to clean the memory somehow? But how? ARC does not allow to use release and so on.. last what i have tried (sorry, maybe not very professional) before to add new subview is this NSArray *viewsToRemove = [self.view subviews]; for (UIView *views in viewsToRemove) { [views removeFromSuperview]; } But this does not help either.. Please don't judge too strong, i am still new to iOS and Objective-c..

  • Having an issue while trying to implement In-App Purchase

    - by Raymond
    This is my first time to implement In-App purchase and I am using the tutorial located here: Ray Wenderlich Now I am sure this is something simple, but I am having issues figuring out, so I figured I would ask all of the gurus out here. The compiler is saying that _products is Use of undeclared identifier - (void)productPurchased:(NSNotification *)notification { NSString * productIdentifier = notification.object; [_products enumerateObjectsUsingBlock:^(SKProduct * product, NSUInteger idx, BOOL *stop) { if ([product.productIdentifier isEqualToString:productIdentifier]) { *stop = YES; } }]; }

  • Replace an Array with an Array

    - by Dane Man
    I have and NSMutableArray and I want to replace it with another, but if I try to do it like this... firstArray = secondArray; ...then it seems to erase the entire firstArray and I get this error message.. Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[NSCFArray objectAtIndex:]: index (0) beyond bounds (0)' ...and the bounds should be (6) not (0). Is there a correct way to replace the array? PS: I already checked the secondArray and it functions fine.

  • Adding a view with a view controller as a subview of another view controller. Doesn't work.

    - by Tom
    I'm trying to essentially re-implement the UISplitViewController (because it has its limits), but when I create a UIViewController viewController, and then do an "[viewController.view addSubview contentViewController.view]" on it, to add a view that already has a view controller, that content view doesn't seem to get initialised by its view controller. I guess its view controller is getting detached or deallocated, is this the case?

  • iPhone rotation on demand

    - by yosh
    Is there a way to manually check current position of device AND ask device to automatically rotate it without waiting for user to actually rotate the device? Currently I control the rotation with several IFs in -shouldAutorotateToInterfaceOrientation but in few situations I have to stop the view from rotating and enable it again and I don't want user to rotate the device twice to have the desired orientation.
