Adding MKMapView Causes Status Bar Issue in iOS 7

Question

I'm solving the status bar issue in iOS 7 using

if(st.version == 7)
{
    CGRect screen = [[UIScreen mainScreen] bounds];
    CGRect frame = self.navigationController.view.frame;
    frame.origin.y = 20;
    frame.size.height = screen.size.height - 20;
    self.navigationController.view.frame = frame;
}

Since I'm using navigation controller and pushing from one to another using [self.navigationController pushViewController:newone animated:YES];. It works fine in all view controllers. But, if the viewcontroller has mkmapview in xib, status bar issue of ios 7 occurs.

If I delete the mapview form xib and push to that view controller means, it will be like,

If I add the mapview even by code below,

mapView = [[MKMapView alloc] initWithFrame:CGRectMake(0, 100, 320, 100)];
[self.view addSubview:self.mapView];

It looks like,

How to solve this?

If you add mapView in viewWillAppear replace it in viewDidAppear.
Maybe you have this issue because you're doing manipulations with view's frames before your view is completely set up
