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

Try Adding the below code in AppDelegate

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

This is the Swift Version:

UINavigationBar.appearance().setBackgroundImage(UIImage.init(named: "navigation.png"), forBarMetrics: UIBarMetrics.Default)

Swift 3 version :

UINavigationBar.appearance().setBackgroundImage(UIImage.init(named: "logo-dark.png"), for: UIBarMetrics.default)

Answer 2

For iOS 7:

[self.navigationController.navigationBar setBackgroundImage:[UIImage imageNamed:@"navbar.png"] forBarMetrics:UIBarMetricsDefault];
