exc-bad-access

This question already has an answer here: Assigning an existing CGColor to a CGColor property works in iOS Simulator, not iOS device. Why? 3 answers I have a custom UIButton class that adds a gradient and a gloss effect to the UIButton the code works perfectly in iOS 4 and on iOS5 simulator but when i run it on iOS 5 devices it gives me the exception EXC_BAD_ACCESS , the exception is triggered by the line : CGContextStrokePath(context); any help is really appreciated , here's my code - (void)drawRect:(CGRect)rect { CGContextRef context = UIGraphicsGetCurrentContext(); CGFloat actualBrightness

I'm coding a library (Obj-C for iPhone) that I want to package and sell, so I obviously need to work out any design kinks before listing it for sale. I am also utilizing this library to help me develop another app. My library is heavily built on task delegation. The primary function I have is to launch a (potentially) long-running process, and when it's done, I call a Delegate Protocol method in the class's delegate. An additional complicating factor here is that I will often schedule this task to fire off every 30 seconds or so. Usually, I do this with [self performSelector:@selector

I created a block, inside a delegate method and I am using it to call a static method in another class. I am getting an EXC_BAD_ACCESS error even when I have NSZombies enabled. There are a few posts on here about similar problems - I think this one is the closest: ARC: Getting EXC_BAD_ACCESS from inside block used in delegate method But, I haven't found anything so far that has helped. Here is the code: @interface MyClass() @property (nonatomic, copy) CaseBlock c; @end .... //NSURLConnection delegate method - (void)connectionDidFinishLoading:(NSURLConnection *)connection { NSDictionary *d =

I just uploaded an app to the appstore, it was developed for ios7. They rejected the app because of a crash I can't reproduce... They sent me this crash report: Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Subtype: KERN_INVALID_ADDRESS at 0x0000000000000008 Triggered by Thread: 0 Thread 0 name: Dispatch queue: com.apple.main-thread Thread 0 Crashed: 0 libobjc.A.dylib 0x000000018e0501c8 objc_msgSend + 8 1 UIKit 0x000000018493e940 __97-[UITabBarController transitionFromViewController:toViewController:transition:shouldSetSelected:]_block_invoke718 + 52 2 UIKit 0x00000001846b6504 -

Upon trying to implement Security.Framework SecKeyRawVerify iOS function from Apple's example, programm halts with bad pointer error (EXC_BAD_ACCESS code=2). Any help or suggestions would be appreciated. Here is my code: - (BOOL)verifySignature:(NSData *)plainText signature:(NSData *)sig { size_t signedHashBytesSize = 0; OSStatus sanityCheck = noErr; SecKeyRef publicKeyA = NULL; NSMutableDictionary * queryPublicKeyA = [[NSMutableDictionary alloc] init]; NSData * publicTag = [NSData dataWithBytes:publicKeyAIdentifier length:strlen((const char *)publicKeyAIdentifier)]; // // Set the public key

I am facing a really strange problem with Core Data. Let's describe it: Definitions Let's say I have two models, ModelA and ModelB . In the data model ModelA has a reference to ModelB as a one-to-many association, and consequently ModelB has a one-to-one association with ModelA . Update When the application launches (especially at first launch), or when the user asks, I have to create or update all the ModelB instances for each ModelA instance. ModelA instances are predetermined. For each ModelA instance I have about 200 instances of ModelB . I use a code like this: ModelB *model =

I have an unreproducible crash on iOS 7 only. I'm making heavy use of MKOverlayRenderer to draw shapes on the map. This crash does not happen on iOS 6. Any ideas of what this might be related to will be useful.

I got this crash report from a remote user, but I cannot find any useful tip to resolve this issue, may be it's a retain problem but I cannot understand why because of I'm using ARC. Very small number of users are issuing this problem. I've tried all things both on simulator and on device (iPhone 4s) without any crash occurs... If I was able to crash on my device it will be very simple to find out what the problem is. Somebody knows how to fix this issue?
