Ok, it’s really really simple for example we have a application like that and we want to set that image to background from navigation bar ok let's show a little the code in the end of file appDelegate.m file, after @end put bellow code
@implementation UINavigationBar (CustomImage)
- (void)drawRect:(CGRect)rect
	UIImage *image = [UIImage imageNamed: @"navbar-iphone.png"];
	[image drawInRect:CGRectMake(0, 0, self.frame.size.width, self.frame.size.height)];
and now... let's see the result For this hint is all up to the next Thanks
