I have a retain property and set to it like this: UINavigationController *thing = [[UINavigationController alloc] initWithRootViewController:one]; // thing's retain count is one nav...

One thing i am not clear about is that, does the memory management of a setter method - (void) setEngine: (Engine *) newEngine { [newEngine retain] [engine releas...
Hi everyone, I have a question regarding to self.view in a UIViewController. First, in my app, everything is created programmatically.

Are (retain) properties retaining t...

In the dealloc function I am releasing all such objects but then realized sometimes i end up releasing objects when they have not been allocated yet.

Hi all, I have an issue with releasing a view too many times. Although simple in theory because im moving uiview to uiview, which is a subclass of uiview and being animated and so on its not something that I can easily fix. It only crashes 10% and only under certain conditions and only 30% of the time even under these conditions. So i...
