    text
    copied!<p>In iOS4 I'm registering the following notification:</p> <pre><code>[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(appWillTerminate:) name:UIApplicationWillTerminateNotification object:[UIApplication sharedApplication]]; -(void)appWillTerminate:(UIApplication *) app { NSLog(@"terminate"); } </code></pre> <p>I know that this is not called in all the situations like in the prev iOS versions, however, simply by registering this I get a <code>EXC_BAD_ACCESSS</code> when the app exits. Still, I can't remove it because my app supports iOS3.0+. How can I handle this? </p> <p>UPDATE: Here is the crash log:</p> <pre><code>Exception Type: EXC_BAD_ACCESS (SIGBUS) Exception Codes: KERN_PROTECTION_FAILURE at 0x00000011 Crashed Thread: 0 Thread 0 Crashed: 0 libobjc.A.dylib 0x0000441c objc_msgSend + 20 1 Foundation 0x00015432 _nsnote_callback + 150 2 CoreFoundation 0x000271da __CFXNotificationPost_old + 390 3 CoreFoundation 0x00026e7a _CFXNotificationPostNotification + 122 4 Foundation 0x00004720 -[NSNotificationCenter postNotificationName:object:userInfo:] + 64 5 Foundation 0x0000de3a -[NSNotificationCenter postNotificationName:object:] + 14 6 UIKit 0x000bef10 -[UIApplication _terminateWithStatus:] + 164 7 UIKit 0x000be1b0 -[UIApplication _handleApplicationSuspend:eventInfo:] + 1980 8 UIKit 0x0007e4a0 -[UIApplication handleEvent:withNewEvent:] + 3620 9 UIKit 0x0007d470 -[UIApplication sendEvent:] + 60 10 UIKit 0x0007ccf8 _UIApplicationHandleEvent + 6804 11 GraphicsServices 0x00005dd8 PurpleEventCallback + 1024 12 CoreFoundation 0x00035e40 __CFRUNLOOP_IS_CALLING_OUT_TO_A_SOURCE1_PERFORM_FUNCTION__ + 22 13 CoreFoundation 0x00035dfe __CFRunLoopDoSource1 + 158 14 CoreFoundation 0x0002809e __CFRunLoopRun + 574 15 CoreFoundation 0x00027d74 CFRunLoopRunSpecific + 220 16 CoreFoundation 0x00027c82 CFRunLoopRunInMode + 54 17 GraphicsServices 0x00004e84 GSEventRunModal + 188 18 UIKit 0x00004f8c -[UIApplication _run] + 564 19 UIKit 0x000024cc UIApplicationMain + 964 </code></pre>
