iOS Warning: Semantic Issue (Multiple methods named 'setDelegate:' found)

Question

I'm new to iOS 5 and having an issue with delegates and segues.

I have a main view controller that segues to a SettingsViewController. I make the main VC the delegate of the Settings VC with this code:

- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
    if ([[segue identifier] isEqualToString:@"SETTINGS"]) {
        [[segue destinationViewController] setDelegate:self];
    }
}

The SettingViewController then segues to multiple option screens. I was trying to make the SettingsViewController the delegate for those option screens, but I get the warning that the setDelegate: method was found in two places (the MainViewController, and the SettingsViewController).

How best to resolve this issue? Thanks!

P.S. I've discovered I only get this warning when I enable Strict Selector Matching warnings in the compiler settings (on the advice of a tutorial book). Leave it off? Fix the problem? I'm not really sure...

Answer 1

It should be sufficient to cast the view controller to the known type:

[(SettingsViewController *)[segue destinationViewController] setDelegate:self];
