Customize NavigationBar in iOS 5

Question

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.

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:...
}

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];

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]; }
