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.

Answer 1

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:...
}
