Set navigation bar image in iOS 7

Question

I want to convert my current project from iOS 6 to iOS 7. In iOS 6 my project is working fine, but in iOS 7 navigation bar image is not showing properly.

I used this code snippet for iOS 6,

UIImage *imgNav = [UIImage imageNamed:@"navigation.png"];
self.navigationController.navigationBar.frame = CGRectMake(0, 0, 320, 44);
[self.navigationController.navigationBar setBackgroundImage:imgNav forBarMetrics:
     UIBarMetricsDefault];

How can I set the navigation bar image in iOS 7?

Answer 1

[[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:@"navigation.png"] forBarMetrics:UIBarMetricsDefault];

Its working if you follow the rules mentioned in ios7 guide: • If you want a solid color with no gradient, create a 1 x 1 point image. • If you want a vertical gradient, create an image that has a width of 1 point and a height that matches the height of the UI element’s background. • If you want to provide a repeating textured appearance, you need to create an image with dimensions that match the dimensions of the repeating portion of the texture. • If you want to provide a nonrepeating textured appearance, you need to create a static image with dimensions that match the dimensions of the UI element’s background area.

Answer 2

Just do this..

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // This will set the backGround image for all the Navigation Bars

    [[UINavigationBar appearance] setBackgroundImage:[UIImage imageNamed:@"navigationBar"] forBarMetrics:UIBarMetricsDefault];



    return YES;
}

Answer 3

if ([self.navigationController.navigationBar respondsToSelector:@selector(setBackgroundImage:forBarMetrics:)] )
{

    UIImage *image = [UIImage imageNamed:@"navigation.png"];
    [self.navigationController.navigationBar setBackgroundImage:image forBarMetrics:UIBarMetricsDefault];
}
