Method to be used inside a VC subclass or VC abstract class to avoid the status bar overlapping feature in iOS7. Actually tested only for single VC not added in hierachy. To use it you should embed all your view subviews into another view called tankView. It should be called before the view controller views has the opportunity to layout its view.

//This should be added before the layout of the view
- (void) adaptToTopLayoutGuide {
    //Check if we can get the top layoutguide
    if (![self respondsToSelector:@selector(topLayoutGuide)]) {
        return;
    }
    //tankView is a contaner view
    NSArray * array = [self.tankView referencingConstraintsInSuperviews]; //<--For this method get the Autolayout Demistified Book Sample made by Erica Sadun
    [self.view removeConstraints:array];
    NSArray * constraintsVertical = [NSLayoutConstraint constraintsWithVisualFormat:@"V:|[topLayoutGuide]-0-[tankView]|" options:0 metrics:nil views:@{@"tankView": self.tankView, @"topLayoutGuide":self.topLayoutGuide}];
    [self.view addConstraints:constraintsVertical];
    NSArray * constraintsHorizontal = [NSLayoutConstraint constraintsWithVisualFormat:@"H:|[tankView]|" options:0 metrics:nil views:@{@"tankView": self.tankView}];
    [self.view addConstraints:constraintsHorizontal];
