setStautsBarStyle: is deprecated in iOS 9?

Hello,

In this video where we are setting the status bar on the iPhone to white. He uses a [application setStatusBarStyle:UIStatusBarStyleLightContent]; in the AppDelegate.m file. The warning I get that is not addressed in the video is 'setStatusBarStyle:' is deprecated: first deprecated in iOS 9 - Use -[UIViewController preferredStatusBarStyle]. Can someone explain what this exactly means and how I fix it. I have searched google and found [[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent]; but that will give me the same answer.

So basically, deprecated means that they have changed the way this is done in iOS 9. The suggestion given, using [UIViewController preferredStatusBarStyle], is the way it is done now. Unfortunately, the way that was presented can be a little misleading. In order to change the status bar style, you actually need to override the preferredStatusBarStyle method. You can do that by putting this code into your ViewController.m file:

- (UIStatusBarStyle)preferredStatusBarStyle {
    return UIStatusBarStyleLightContent;
}

Hope this helps!

Couldn't find info on this method in the docs. Thanks! I tried to implement it using self in viewController.m, like so: 

[self preferredStatusBarStyle: UIStatusBarStyleLightContent];

Needless to say, that didn't work...

You should be putting the snippet of code that I wrote above into your ViewController.m file.

I got that part. I know what overloading is. Just didn't know how it worked in Obj-C. Thanks anyway.

Oh you got me wrong. I was saying that I had tried doing it the other way, and couldn't figure out how to get it to work until I found your answer. It really helped.

In addition to including the ViewController#preferredStatusBarStyle method — as described by Keli'i Martin above — you also need to make sure that the View controller-based status bar appearance property of your project is set to NO. This property is what allows the ViewController to change the color of the StatusBar instead of the AppDelegate doing it.

Hi Keli, so...the didFinishLaunchingWithOptions end up like this?

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Override point for customization after application launch.
    return YES;
}
