Statusbar - How to hide/show status bar in i Os

The status bar can be gradient gray (with black text), black opaque (with white text), or black translucent. By default the status bar is gray. If your app features standard iPhone UI elements, then stick with the default status bar. However if your app has custom views with dark backgrounds, then a black status bar will look better.
Black and white status bars push the underlying views down, giving you 320 x 460 pixels of screen space to work with in your app. A translucent status bar overlays the underlying view, giving you the full 320 x 480 pixels of screen space.
You can set the status bar style either programmatically or in your Info.plist file. If you change it in Info.plist, then the style is changed when the app launches (while the app is loading). If you change it programmatically, then the style changes after the app finishes loading.


//To hide
    [[UIApplication sharedApplication] setStatusBarHidden:YES withAnimation:UIStatusBarAnimationFade];


//To Show
    [[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:UIStatusBarAnimationFade];
