http://blog.csdn.net/iorchid/article/details/

@interface UINavigationBar (MyCustomNavBar)
@end

@implementation UINavigationBar (MyCustomNavBar)
- (void) drawRect:(CGRect)rect
{
    UIImage *barImage = [UIImage imageNamed:@"title.png"];
    [barImage drawInRect:rect];
}
@end

方法二：

[cpp] view plaincopy

- (void)viewWillAppear:(BOOL)animated
{

    UIImageView *imageView = [[UIImageView alloc] initWithFrame: CGRectMake(0.0f, 0.0f, 320.0f, 44.0f)];
    imageView.image = [UIImage imageNamed: @"title.png"];
    [self.navigationController.navigationBar addSubview: imageView];
}
