Customize NavigationBar in iOS 5

In iOs4 i created a custom navigation bar using this snippet 

#import "UINavigationBar+CustomImage.h"


@implementation UINavigationBar (CustomImage)

- (void)drawRect:(CGRect)rect {
    // Drawing code
    UIImage *image = [[UIImage imageNamed:@"header.png"] retain];
    [image drawInRect:CGRectMake(0, 0,self.frame.size.width , self.frame.size.height)];
    [image release];
    }
@end

and it is well for ios4 in my app. Now I want to run this in iOs5 and the problem is that the custom navigation bar doesn't appear the way I want.

Can any one help me to create a custom navigation bar for iOs5.

Check the iOS version and set the navigation bar image

if([[[UIDevice currentDevice] systemVersion]floatValue] <5.0){ } else{
[[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:@"Sample.png"] forBarMetrics:UIBarMetricsDefault]; }

Just put the following code in the application delegate and it will work fine, Even in ios5
I put it in 

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions


// Create image for navigation background - portrait

UIImage *NavigationPortraitBackground = [[UIImage imageNamed:@"NavigationPortraitBackground"] 
                                             resizableImageWithCapInsets:UIEdgeInsetsMake(0, 0, 0, 0)];

// Create image for navigation background - landscape

UIImage *NavigationLandscapeBackground = [[UIImage imageNamed:@"NavigationLandscapeBackground"] 
                                          resizableImageWithCapInsets:UIEdgeInsetsMake(0, 0, 0, 0)];


// Set the background image all UINavigationBars

[[UINavigationBar appearance] setBackgroundImage:NavigationPortraitBackground 
                                   forBarMetrics:UIBarMetricsDefault];
[[UINavigationBar appearance] setBackgroundImage:NavigationLandscapeBackground 
                                   forBarMetrics:UIBarMetricsLandscapePhone];

You need to use the appearance proxy. But, make sure to check if respondsToSelector for iOS4. Leave your current method in place for iOS4 and it will work on both.

// not supported on iOS4
UINavigationBar *navBar = [purchaseNavController navigationBar];
if ([navBar respondsToSelector:@selector(setBackgroundImage:forBarMetrics:)])
{
    // set globablly for all UINavBars
    [[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:@"brnlthr_nav.jpg"] forBarMetrics:UIBarMetricsDefault];

    // could optionally set for just this navBar
    //[navBar setBackgroundImage:...
}
