Question

I created two ViewControllers (Xcode 4 => Storyboard). After that I created two UIViewSubclasses, called PlayOutControlViewController.h and TVOutViewController.h.

I want to display a video on an external Display, so I tried the following:

(MediaPlayer.framework added, Changed the class of my UIViewSubclasses to PlayOut… and TVOut… – Controller.h)

PlayoutViewController.m

[TVOutViewController.view addSubview: MediaPlayer.view];
//Got Error: Property view not found on object of type TVOutViewController

[TVOutViewController addSubview: MediaPlayer.view]; //Got an Error
//Got Error: No known class method for selector addSubview

Sorry, I know what the Errors mean, but not how to fix them.

Thanks in advance!

P.S. I’m in the PlayoutViewController.m, where:

[self.view addSubview: (anyUIView)];
//works

//and

[PlayoutViewController.view addSubview: (anyUIView)];
//won't work.

… Thank you!

Thanks so far.

My TVOutViewController is a subclass of UIViewController, as described here:

@interface TVOutViewController : UIViewController {    }

I added a UIView to the TVOutViewController in InterfaceBuilder. Do I have to do something else to be able to do like:

[self.view addSubview: AnyUIView];

Second question:

If I declare a method in TVOutViewController.m, like:

+(void)addSubviewMethod:(id)sender { [self.view addSubview: AnyUIView]; }

Why am I not able to call it in the PlayoutControlViewController.m via

[TVOutViewController addSubviewMethod];

I added

#import "TVOutViewController.h";

to the PlayOutViewController.m file.

Thank you all in advance!

OK SOLVED:

You were on the right track:

I forgot to initialize the object. Now it works like a charm!

TVOutViewController *MoviePlayerView = [[TVOutViewController alloc] init];
[MoviePlayerView.view addSubview:moviePlayer.view];
