You can use Container View. Add a container view to your parent view and add other view controllers in your container view.

 self.addChildViewController(vc)
vc.view.frame = CGRectMake(0, 0, self.container.frame.size.width, self.container.frame.size.height);
self.container.addSubview(vc.view)
vc.didMoveToParentViewController(self)
