How do I solve this problem?
The delegate property is deprecated in AVAudioSession and it is replaced with a Notification AVAudioSessionInterruptionNotification. So rather using delegate property register for this notification. Image depicting the same from header of AVAudioSession.h -

Below are the crash logs from an iPad. I'm getting this crash randomly while I'm pushing and popping out a UIViewController from Navigation controller. Any help/pointer is appreciated.

Was able to figure out long back but forgot to update here. KVO observer not removed! Silly me :-|. BTW thanks for the support. SO rocks.
Most probably you forgot to clear some delegates before releasing an object.
I have a random-looking crash related to UIKit and I can't seem to figure out what is wrong.
Does anyone see a familiar pattern here or do you think this might be a random OS-related crash? Is there a way to find out which Buttons or UI-elements were involved here?

Im developing my app and yesterday while I was playing with it crashed. I wasnt debugging, so I thought I'd take a look at the crash log today.
But my surprise is that I can't see anything that can give me some info, here it is:

Hope you can help me with this, thanks.
Without the app still in memory I'm not sure there's much you can do. From experience I guess you messaged an object that has been dealloc'd. (Maybe the datasource object for your MKMapView?) I'd try running your app with zombies enabled to track it down.
[recorder deleteRecording]; works well 30 times, but around 31 it crashes.

I found that this happens when deleteRecording is trying to delete a non existent file. So check if file exists before you call it:
if ([[NSFileManager defaultManager] fileExistsAtPath:self.recorder.url.path]) {
if (![self.recorder deleteRecording])
NSLog(#"Failed to delete %#", self.recorder.url);
}
It must be a bug in AVAudioRecorder.
I'm experience an occasional crash of my iPhone application where I'm getting the following exception
NSGenericException', reason: '*** Collection <CALayerArray: 0x26f6b0> was mutated while being enumerated.

This crash is being triggered after the following code is executed.
StopRouteViewController *stopVC = [[StopRouteViewController alloc] init];
[UIView transitionWithView:self.navigationController.view
duration:0.5
options:UIViewAnimationOptionTransitionFlipFromLeft
animations:^{
[self.navigationController pushViewController:stopVC animated:NO];
}
completion:NULL];
[stopVC release];
Does this look blatantly wrong to anyone? My current thought is that is is either tied to stopVC being released before it is pushed or with transitioning with navigationController.view while at the same time pushing a new viewController to the navigationController.
Since this only occurs occasionally, I'd like to have a little more confidence before I commit a potential fix.
Yes, this is incorrect usage of the API. -[UINavigationController pushViewController:animated:] handles animation on its own. Even if you pass NO as the second argument, it is still manipulating the view hierarchy, which is what's causing your crash.
Basically, there is no reason to put a call to -[UINavigationController pushViewController:animated:] in an animation block, as you have done. If you want to animate the push of your controller, pass YES as the second argument.
