I'm looking at this code:
NSMutableArray *controllers = [[NSMutableArray alloc] init];
for (unsigned i = 0; i < kNumberOfPages; i++) {
[controllers addObject:[NSNull null]];
}
self.viewControllers = controllers;
[controllers release];
Later on...
- (void)dealloc {
[viewControllers release];
...
}
I see that self.viewControllers and controllers now point to the same allocated memory (of type NSMutableArray *), but when I call [controllers release] isn't self.viewControllers released as well, or is setting self.viewControllers = controllers automatically retains that memory?
