iPhone: Calling dealloc on parentViewController causes an exception
- by arielcamus
Hi,
I'm dealing with viewDidUnload and dealloc methods and I've founded a problem when calling [super dealloc]; in parent view controller.
I have a lot of view controllers with custom code which I have putted outside on a parent view controller. So, when defining my view controllers I set a reference to the super class:
@interface LoginViewController : AbstractViewController
Then, at the dealloc method I call the AbstractViewController dealloc method:
//(Login View Controller code)
- (void)dealloc {
[user release];
[passwd release];
[super dealloc];
}
[super dealloc] execute the following code:
//(Abstract View Controller code)
- (void)dealloc {
[dbUtils release];
[loadingView release];
[super dealloc];
}
If I simulate a memory warning on iPhone Simulator, the following exception is thrown:
2010-03-03 11:27:45.805 MyApp[71563:40b] Received simulated memory warning.
2010-03-03 11:27:45.808 MyApp[71563:40b] *** -[LoginViewController isViewLoaded]: message sent to deallocated instance 0x13b51b0
kill
quit
However, if I comment the [super dealloc] line in AbstractViewController the exception is not thrown and my app still running.
Thank you for your help once again!
