Question

I am styling my UINavigationController with a custom image, however, this looks quite bad in a Popover, is there a way to do this only for navigation controllers, which are not in a popover?

I currently do this in my AppDelegate.m:

- (void)applyCustomStyling{
    [[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:@"TitleBar.png"] forBarMetrics:UIBarMetricsDefault];
    [[UIToolbar appearance] setBackgroundImage:[UIImage imageNamed:@"TitleBar.png"] forToolbarPosition:UIToolbarPositionAny barMetrics:UIBarMetricsDefault];
}

So if you don’t believe that it looks bad:

This is how it should be (UIPopover-default):

You can use appearanceWhenContainedIn1 to have more granular control of appearance based on your controller hierarchy:

[[UINavigationBar appearanceWhenContainedIn:[UIPopoverController class], nil]
                         setBackgroundImage:nil 
                              forBarMetrics:UIBarMetricsDefault];
