Question

Observe this perfectly simple UIViewController subclass method:

-(IBAction)launchSearch
{
    OffersSearchController *search = [[OffersSearchController alloc]
                                      initWithNibName:@"OffersSearchView" bundle:nil];
    EverWondrAppDelegate *del = [UIApplication sharedApplication].delegate;
    [del.navigationController pushViewController:search animated:YES];
    [search release];
}

On the line where I get *del, I am getting a compiler warning that reads, Type 'id <UIApplicationDelegate>' does not conform to the 'CLLocationManagerDelegate' protocol. In fact, my app delegate DOES conform to that protocol, AND what I’m doing here has nothing at all to do with that. So what’s up with that message?

Secondary question: sometimes I can get to my navigationController via self.navigationController, and sometimes I can’t, and have to go to my app delegate’s property to get it like I’m doing here. Any hint about why that is would be very useful.

Answer 1

Try this:

EverWondrAppDelegate *del = (EverWondrAppDelegate *)[UIApplication sharedApplication].delegate;

With regards to your second question: no idea why this would be happening.
