add UIViewController in subview

Question

I don\'t know if this is the right key to search \"add UIViewController in subview\". As what you can see in my image ,there are two ViewController, the main and the second

Answer 1

I've try to use this code:

SecondViewController *secondViewController = [[SecondViewController alloc] initWithNibName:nil bundle:nil];

 secondViewController.view.frame = CGRectMake(0, 0, self.mySubView.bounds.size.width, self.mySubView.bounds.size.height);

 [self addChildViewController:secondViewController];
 [self.viewDialogSolution addSubview:secondViewController.view];

but I see only myview not the layout of secondViewController.

Ho to resolve the probleam?

Thanks a lot
