Add a ContainerView inside a UIViewController created from .xib

Question

I have a .xib file and i want to add it a container view (to place inside a ViewController). Unfortunately a container view is only disposable by storyboard. But when i create a .xib file and i search for the container view controller, i don´t found it. Can someone give me a tips how to achieve my task?

If you're using a xib instead of a storyboard, you can just add a plain UIView to the xib to act as a container. Then in code, add your childViewController's view as a subview of the container. Here, I've followed the appropriate child view controller methods and added layout constraints to ensure its frame updates with the container's frame:

- (void)viewDidLoad {     [super viewDidLoad];      UIViewController *childViewController = ...; // create your child view controller      [self addChildViewController:childViewController];     [self.containerView addSubview:childViewController.view];     [childViewController didMoveToParentViewController:self];      NSArray *horzConstraints = [NSLayoutConstraint constraintsWithVisualFormat:@"H:|[childView]|"                                                                    options:0                                                                    metrics:nil                                                                      views:@{@"childView" : childViewController.view}];      NSArray *vertConstraints = [NSLayoutConstraint constraintsWithVisualFormat:@"V:|[childView]|"                                                                    options:0                                                                    metrics:nil                                                                      views:@{@"childView" : childViewController.view}];      [self.view addConstraints:horzConstraints];     [self.view addConstraints:vertConstraints];      childViewController.view.translatesAutoresizingMaskIntoConstraints = NO; }
