Question

Seems like a shockingly trivial difference. Passing a non-nil value for otherButtonTitles to UIAlerView blows up.

Working:

UIAlertView *alert = [[UIAlertView alloc]
                      initWithTitle:@"Login with your credentials"
                      message:nil
                      delegate:nil
                      cancelButtonTitle:@"Cancel"
                      otherButtonTitles:nil];

Not working:

UIAlertView *alert = [[UIAlertView alloc]
                      initWithTitle:@"Login with your credentials"
                      message:nil
                      delegate:nil
                      cancelButtonTitle:@"Cancel"
                      otherButtonTitles:@"OK"];

What gives?

Answer 1

UIAlertView *alert = [[UIAlertView alloc]
                      initWithTitle:@"Login with your credentials"
                      message:nil
                      delegate:nil
                      cancelButtonTitle:@"Cancel"
                      otherButtonTitles:@"OK1",@"OK2",nil];

Last argument is a multiple argument, should be terminated by nil.
