How to set UIViewController “extend edges” properties

Question

I see the following selections in Storyboard for extending the edges of a UIViewController\'s view under navBars/tabBars:

Answer 1

In Objective-C:

- (void) viewDidLoad {
   [super viewDidLoad];
   [self initVars];
}

- (void) initVars {
   self.edgesForExtendedLayout = UIRectEdgeTop | UIRectEdgeLeft | UIRectEdgeRight | UIRectEdgeBottom;
   self.extendedLayoutIncludesOpaqueBars = YES;
}

The properties that you want is:

self.edgesForExtendedLayout = UIRectEdgeTop | UIRectEdgeBottom;
