In iOS 7 status bar appearance depends on <code>UIViewController</code> as default. To hide status bar globally, in <code>info.plist</code> use <code>NO</code> value for <code>UIViewControllerBasedStatusBarAppearance</code> key and use <code>UIApplication</code>'s <code>setStatusBarHidden</code> method with <code>YES</code> <code>BOOL</code> value.

I had the same problem, but its an easy fix! Just set 

<pre><code>status bar is initially hidden = YES
</code></pre>

then add an row by clicking on the plus right after the text <code>status bar is initially hidden</code>, then set the text to

<pre><code>view controller-based status bar appearance
</code></pre>

by clicking the arrows, and set it to <code>NO</code>

Hope this helps!

To hide status bar for each individual view controller programmatically, use any of the following two procedures:

<h2>Procedure 1:</h2>

[[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationNone];

<h2>Procedure 2:</h2>

-(BOOL)prefersStatusBarHidden {

<pre><code> return YES;
</code></pre>

}

To hide status bar for the entire application, we should follow the given below procedure:

You should add this value to plist: "View controller-based status bar appearance" and set it to "NO".
