Application crash on waking app from idle

0

My app is crashing when I wake it up from idle after long time. This is not always reproducible but it happens every third or fourth time. In my viewWillAppear I am calling some methods on self object.

The crash log says:

Try autorelease on UIAlertView or other UI elements that you displayed. May be you have forgotten to retain some of them.

-[UIAlertView(Private) _popoutAnimationDidStop:finished:] issue appears when you are calling your alertview after you have released it. If you aren't using Automatic reference counting in your code, release your alertview only in your dealloc method like this:

-(void)dealloc {
    self.alertView.delegate = nil; //setting delegate to nil
    self.alertView = nil; //if you have defined alert as property
    //other release statements of your controller
    [super dealloc];
}
