How to add an UIViewController s view as subview

Question

Note to googlers  this Q-A is now six years out of date   As Micky below and others mention  this is now done on an everyday basis with Containers in iOS     I have a ViewController which controls many subviews  When I click one of the buttons I initialize another viewcontroller and show it s view as the subview of this view  However the subview exceeds the bounds of the frame for subview and infact fills the entire screen   What could be wrong  I presume the problem is that UIViewController s view has a frame  0 0 320 460  and hence fills the entire screen  though it receive s touch events only when touched within the subview frame bounds   How can I resize the frame to fit as subview   In short  I need help adding a viewcontroller s view as a subview to another viewcontroller s view   Thanks

You may use PopupController for the same one the SDK which shows UIViewController as subview You may check PopupController

Here is sample code for the same

popup = PopupController
        .create(self.navigationController!)
        .customize(
            [
                .layout(.center),
                .animation(.fadeIn),
                .backgroundStyle(.blackFilter(alpha: 0.8)),
                .dismissWhenTaps(true),
                .scrollable(true)
            ]
        )
        .didShowHandler { popup in
        }
        .didCloseHandler { popup in
    }
    let container = MTMPlayerAndCardSelectionVC.instance()
    container.closeHandler = {() in
        self.popup.dismiss()
    }

    popup.show(container)

As of iOS 5  Apple now allows you to make custom containers for the purpose of adding a UIViewController to another UIViewController particularly via methods such as addChildViewController so it is indeed possible to nest UIViewControllers  EDIT  Including in-place summary so as to avoid link breakage  I quote      iOS provides many standard containers to help you organize your apps  However  sometimes you need to create a custom workflow that doesn   t match that provided by any of the system containers  Perhaps in your vision  your app needs a specific organization of child view controllers with specialized navigation gestures or animation transitions between them  To do that  you implement a custom container - Tell me more         and      When you design a container  you create explicit parent-child relationships between your container  the parent  and other view controllers  its children - Tell me more   Sample  courtesy of Apple docs  Adding another view controller   s view to the container   s view hierarchy  -  void  displayContentController   UIViewController   content       self addChildViewController content                       content view frame    self frameForContentController        self view addSubview self currentClientView       content didMoveToParentViewController self

You must set the bounds properties to fit that frame  frame its superview properties  and bounds limit the frame in the view itself coordinate system

I feel like all of these answers are slightly incomplete  so here s the proper way to add a viewController s view as a subview of another viewController s view        self addChildViewController viewControllerToAdd        self view addSubview viewControllerToAdd view        viewControllerToAdd didMoveToParentViewController self     If you d like  you can copy this into your code as a snippet   SO doesn t seem to understand code replacement formatting  but they will show up clean in Xcode        self addChildViewController  lt  viewControllerToAdd  gt         self view addSubview  lt  viewControllerToAdd  gt  view         lt  viewControllerToAdd  gt  didMoveToParentViewController self     willMove is called automatically w  addChild  Thanks  iOSSergey     When your custom container calls the addChildViewController  method  it automatically calls the willMoveToParentViewController  method of the view controller to be added as a child before adding it

This answer is correct for old versions of iOS  but is now obsolete  You should use Micky Duncan s answer  which covers custom containers   Don t do this  The intent of the UIViewController is to drive the entire screen  It just isn t appropriate for this  and it doesn t really add anything you need   All you need is an object that owns your custom view  Just use a subclass of UIView itself  so it can be added to your window hierarchy and the memory management is fully automatic   Point the subview NIB s owner a custom subclass of UIView  Add a contentView outlet to this custom subclass  and point it at the view within the nib  In the custom subclass do something like this   -  id initWithFrame   CGRect inFrame        if    self    super initWithFrame  inFrame                 NSBundle mainBundle  loadNibNamed    NibNameHere                                        owner  self                                     options  nil           contentView size   inFrame size             do extra loading here          self addSubview  contentView             return self     -  void dealloc        self contentView   nil         additional release here      super dealloc        I m assuming here you re using initWithFrame  to construct the subview
