UINavigationBar's drawRect is not called in iOS 5.0

Question

I\'ve overrided(placed in category, or swizzled) UINavigationBar\'s drawRect to show custom background. In iOS 5 it\'s not working. What should I do?

Answer 1

@implementation UINavigationBar (MyCustomNavBar)

- (void)setBackgroudImage:(UIImage*)image
{
    CGSize imageSize = [image size];
    self.frame = CGRectMake(self.frame.origin.x, self.frame.origin.y, self.frame.size.width, imageSize.height);
    UIImageView *backgroundImage = [[UIImageView alloc] initWithImage:image];
    backgroundImage.frame = self.bounds;
    [self addSubview:backgroundImage];
    [backgroundImage release];
}
@end

The above swizzling will allow you to set any custom background image for the UINavigationBar(iOS5 & iOS4).
