application get crashed while i开发者_高级运维nvoking [self.view popViewController animated:YES], any reason why this happens ?????

If you have push any viewcontroller then only u can pop the controller.

There may be a some problem in viewWillAppear method of the pop controller.

before pop the controller that controller must be release all of the resources that used.so that in ur dealloc method do some research.or else u will be release the any resources twice.check out this.
