using image or tint color on uinavigationbar in iphone?

Question

how do i show a background image on a navigation bar or give tint color to the navigation bar in a native iphone application??

Answer 1

This's how I did on iOS4:

#import  // For .layer 

self.navigationController.navigationBar.layer.contents = (id)[UIImage imageNamed:@"navigationBarBackgroundImage"].CGImage;
self.navigationController.navigationBar.tintColor = [UIColor orangeColor];

No need to switch subviews between z-orders (-exchangeSubviewAtIndex:withSubviewAtIndex:), both background image and tintColor set in one line of code, and works with @2x image too.
