Status bar and navigation bar issue in IOS7

Question

I am migrating my application to iOS 7. For handing the status bar issue I have added this code

if([[[UIDevice currentDevice] systemVersion] floatValue] >         


        

Answer 1

just set the following code in viewWillAppear.

 if ([[[UIDevice currentDevice] systemVersion] floatValue]<= 7) {
    self.edgesForExtendedLayout = UIRectEdgeNone;
 }
