Question

Im trying to use the NSLog, to print console messages. The problem is sometimes i receive a “EXC_BAD_ACCESS” error when calling it

-(void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration
{
NSLog(@"Working test %d", toInterfaceOrientation);
NSLog(@"EXC_BAD_ACCESS %@", toInterfaceOrientation);
}

Here i simply want to see what the arguments passed into the function contain. The first NSLog works fine. The second causes an “EXC_BAD_ACCESS” and i dont understand why?.

Answer 1

%@ only works with objects. And toInterfaceOrientation is not an object.

As you can see in the documentation for UIInterfaceOrientation it’s just an enum.
