I just downloaded the crash reports for one of my iPhone apps from iTunes Connect. The most common crash has a trace like the following: Exception Type: EXC_BAD_ACCESS (SIGSEGV) Exception Codes: KERN_INVALID_ADDRESS at 0xa1b1c1db Crashed Thread: 0 Thread 0 Crashed: 0 libobjc.A.dylib 0x3030e6f4 objc_msgSend + 16 1 UIKit 0x30ebebee -[UIWebView webView:resource:didFinishLoadingFromDataSource:] 2 UIKit 0x30ebe5ca -[UIWebViewWebViewDelegate webView:resource:didFinishLoadingFromDataSource:] 3 CoreFoundation 0x32b73b5c __invoking___ + 60 4 CoreFoundation 0x32bc67be -[NSInvocation invoke] 5 WebCore 0x320baa86 HandleDelegateSource 6 CoreFoundation 0x32bb8a96 CFRunLoopRunSpecific 7 CoreFoundation 0x32bb8356 CFRunLoopRunInMode 8 GraphicsServices 0x30544cd4 GSEventRunModal 9 GraphicsServices 0x30544d80 GSEventRun 10 UIKit 0x30d2c768 -[UIApplication _run] 11 UIKit 0x30d2b46c UIApplicationMain I'm about 80% sure this is an issue internal to UIWebView and outside the scope of what I can address. Does anyone have any suggestions on how to narrow down this issue to help identify whether it's an issue with the OS and UIWebView, or an issue that I can fix and address in my code? Thanks in advance. UPDATE: The UIWebView in question is in a view that gets released when the user hits the back button of the corresponding navigation controller. The accepted solution seems to provide a good explanation for why this error is occurring. Before suggested solution: - (void)dealloc { [webView release]; [super dealloc]; } After suggested solution: - (void)dealloc { webView.delegate = nil; [webView stopLoading];
