iOS 6/7 Deltas: Only working for subviews?

Question

I designed my iPhone app for iOS 5 and 6. Now I want it to support iOS 7 but the two older versions as well. Like many developers I have been struggling with the status bar overlapping my views and I understand that there is no way to preserve the old status bar style in iOS 7.

Yet many posts on Stackoverflow suggest to use the iOS 6/7 Deltas which can be set in Xcode with the new SDK:

I have tried that but I have found that nothing happens when I apply these values to the root view of a view controller. These Deltas only have an effect on all the subviews contained within the root view.

Why do the Deltas not work for the root view? Is there a way to make it work? (I do not want to add Deltas to all my UI elements in all my view controllers.)

Answer 1

I have found this work around which works fine for me.

 -(void)viewWillLayoutSubviews
{
    if (floor(NSFoundationVersionNumber) <= NSFoundationVersionNumber_iOS_6_1) 
   {
    // Load resources for iOS 6.1 or earlier
    if(IS_IPhone5)
    {
        self.view.frame = CGRectMake(0.0, -64.0, 320.0, 568.0);
    }
    else
    {
      self.view.frame = CGRectMake(0.0, -64.0, 320.0, 480.0);  
     }
   }

 }

From you question What I think is you seems tired of setting delta values for individual subviews. But its very easy I think. Just select all the subviews:

and you can add same delta values for all your subviews from size inspector at one shot...as simple as that!!
