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

But my status bar is not displayed(Please see the picture). I use this code in 2 project but other project is ok. I dont know what i am doing wrong Please help me.

This result I dont want

This status bar is correct.

Answer 1

In Info.plist set 'View controller-based status bar appearance' as NO

In AppDelegate add

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{
  [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];
}  

This solution works for iOS 7
