Question

I am trying to present a modal view controller. I have read the documentation, but something is strange. Here’s my code:

NSLog(@"rc: %d", [modalViewController retainCount]);
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:modalViewController];
[self presentModalViewController:navigationController animated:YES];
[navigationController release];
NSLog(@"rc: %d", [modalViewController retainCount]);

And on the console, appears:

rc: 2
rc: 24

And I think 24 is very strange… What do you thin? Why is this happening?

Answer 1

You shouldn’t worry about the value of retain count too much. When using system calls like this, any number of retain/release cycles can occur.

If your view controller is being presented modally correctly, then what’s the problem?
