float systemVersion= [[[UIDevice currentDevice] systemVersion] floatValue];

if(systemVersion >= 7.0f)
{
  self.edgesForExtendedLayout=UIRectEdgeNone;   
}

Use this code in your viewDidLoad() method.

Apple suggest you detect the system version via `if (floor(NSFoundationVersionNumber) > NSFoundationVersionNumber_iOS_6_1) {` for iOS 7. As stated in there [iOS 7 UI Transition Guide](https://developer.apple.com/library/ios/documentation/UserExperience/Conceptual/TransitionGuide/SupportingEarlieriOS.html#//apple_ref/doc/uid/TP40013174-CH14-SW1). So don't use `[[UIDevice currentDevice] systemVersion]` – rckoenes Oct 08 '13 at 09:13

this code work only in this case if you are using navigation controller and navigation bar is visble. – Kalpesh Oct 08 '13 at 09:20

For hiding navigation Bar : USe the following code :

if (floor(NSFoundationVersionNumber) > NSFoundationVersionNumber_iOS_6_1) {

self.edgesForExtendedLayout=UIRectEdgeNone; }

And in For hiding StatusBar set the following property to YES in plist :-

Status bar is initially hidden

As the Table View display white cells because in iOS7.0 the cell background color is white by default so just set it clear colour :
Here is the Code :-
- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath { [cell setBackgroundColor:[UIColor clearColor]]; }
