UIImagePicker's UINavigationBar is abiding to drawRect. How can I stop this?

[iSDK]

Hi,

I am using the following code to set the backgrounds of all UINavigationBars in my application. However, when I load the UIImagePicker, its' UINavigationBar will have the same backgroundView as all of the other UINavigationBars in my application.

How could I prevent this from happening?

Max

@implementation UINavigationBar (UINavigationBarCategory)

- (void) drawRect:(CGRect)rect {
    [[UIImage imageNamed:@"NavBarSocial.png"] drawInRect:rect];
}
@end

If I understand correctly, you want all UINav controllers except the imagepicker's to have you custom nav bar?

- (void) drawRect:(CGRect)rect {
  if( [self isKindOfClass: [UIImagePickerController class]])
  {
     [super drawRect: rect];
   }
   else [[UIImage imageNamed:@"NavBarSocial.png"] drawInRect:rect];
}

The category is just implemented in one of my .m files it is not part of a custom UINavigationBar. Therefore the code wouldn't work as a 'self''s class is of UINavigationBar class rather than UIImagePickerClass. But yes, that is what I would like.

what about this:

-(void)drawRect:(CGRect)rect
{
    UIView* _super = [self superview];
    while(_super !=nil )
    {
        UIResponder* next = [_super nextResponder];
        if( [next isKindOfClass:[UIImagePickerController class]])
        {
              //if this UINavigationBar lives inside of a UIImagePickerController, 
             //then we'll use the default drawRect instead of our own
            [super drawRect:rect];   
             return;
        }
        _super = [_super superview];
    }
   
    [[UIImage imageNamed:@"NavBarSocial.png"] drawInRect:rect];
}

Works perfectly, thanks a lot!
