In my app I have a UIViewController subclass (VC for short) that I only use in one place in the entire app. In that place, I have been creating and pushing it like this:
MyViewController* VC = [MyViewController new];
[self.navigationController pushViewController:VC animated:YES];
[VC release];
but I was thinking that since this is the only place I am using a view controller of this type, I could do something like this so the settings used won't be reset each time the view controller is pushed onto the stack:
static MapsToSendPicker* VC = nil;
if(!VC) {
VC = [MapsToSendPicker new];
}
[self.navigationController pushViewController:VC animated:YES];
[VC release];
The problem with that code is that in VC's dealloc method, I release all of my instance variables and set them to nil, and finally I call [super dealloc]. This deallocates the static view controller, but the test if(!VC) isn't evaluated to true after (this would defeat the purpose of the whole idea if it were; then I'd have to recreate the view controller each time anyway).
My solution is overriding the dealloc method in MyViewController and not calling [super dealloc] at the end. This works, but the compiler raises a warning. How can I get rid of that warning while maintaining the functionality I gain with this design? Thanks!
Edit:
After a quick Google search, I have found this solution:
- (void)dealloc {
if(NO) {
[super dealloc];
}
}
but I would like something a little bit... cleaner. Any thoughts?
