iOS状态栏-View Controller到Navigation Controller

Question

I have done a little research and understand that a quick fix for iOS 7+ suffering from the overlying status bar issue (introduced in iOS 7 with the new status bar layout) on a view controller is to put it in a Navigation Controller.

However, when I go to Xcode the option is greyed out. What am I doing wrong? (I am an Xcode beginner, so bear with me).

Is using a Navigation Controller the correct way to do it?

As you can see here, the Navigation Controller is behind the status bar, not extended below it:

Answer 1

Its looking like that your controller is already in a Navigation controller stack, thats why it is not showing the option to embed in Navigation controller. Check your storyboard.

Answer 2

You Create Xib its set the Top Bar or Navigation Bar, select the XIB then see the right side select Attributes Inspector then set the status bar, Top Bar etc, then see my screenshot below,

create UIBarbutton programmatically code is below,

viewDidLoad Method:

UIBarButtonItem *leftBarButtonItem = [[UIBarButtonItem alloc] initWithImage:[UIImage imageNamed:@"imageName"] style:UIBarButtonItemStylePlain target:self action:@selector(backAction)];
[self.navigationItem setLeftBarButtonItem:leftBarButtonItem animated:NO];

its working for me, hope its helpful
