Question

I am trying to remove a warning from this line:

UIViewController * appController = [[[UIApplication sharedApplication] delegate]     viewController];

The warning I get for this line of code is the following:
“instance method ‘viewController’ not found (return type defaults to ‘id’)

Can someone help explain how I might remove this waning?

Thanks a lot,

You need to cast your application delegate:

UIViewController * appController = [(MyAppDelegate *)[[UIApplication sharedApplication] delegate] viewController];
