Automatic Reference Counting Issue in Xcode 4.2

Automatic Reference Counting Issue
Receiver type 'JasperMobileAppDelegate' for instance message does not
declare a method with selector 'setResourceClientForControllers:'
- (IBAction)configureServersDone:(id)sender {
[self setResourceClientForControllers:self.resourceClient];
[tabBarController setSelectedIndex:0];
}
How to fix this?
Thank You
