I’ve got an OpenGL MacOS game, my MacOS is 10.13.4 with all recent updates.
When the game switches windowed -> fullscreen, everything is fine.
When is switches fullscreen->windowed it renders the full screen white, while in focus, but it renders fine when it not in focus.
And the game runs initially fine both in fullscreen and windowed modes.
The code is quite old, this is not the first game uses this code, and I don’t remember I saw this issue on previous MacOS versions.
Here is my code:
- (void)toggleFullscreen:(const bool)value
{
if (value)
{
if (mFullScreenWindow)
return;
mFullScreenWindow = [[GameFullscreenWindow alloc] init];
NSRect viewRect = [mFullScreenWindow frame];
[mGameView stopDisplayLink:YES];
[mGameView setFrameSize: viewRect.size];
[mFullScreenWindow setContentView:mGameView];
[mFullScreenWindow makeKeyAndOrderFront:self];
RendererGLOSX::SaveDisplaySize(Vec2(viewRect.size.width, viewRect.size.height));
}
else
{
if (mFullScreenWindow == nil)
return;
NSRect viewRect = [mWindow contentRectForFrameRect:[mWindow frame]];
[mGameView stopDisplayLink:YES];
[mGameView setFrame:viewRect];
[mWindow setContentView:mGameView];
[mWindow makeKeyAndOrderFront:self];
[mFullScreenWindow release];
mFullScreenWindow = nil;
RendererGLOSX::SaveDisplaySize(Vec2(viewRect.size.width, viewRect.size.height));
}
[mGameView stopDisplayLink:NO];
}
That was mFullScreenWindow rendered.
The issue was fixed by adding [mFullScreenWindow orderOut: self] before [mFullScreenWindow release].
I started a blank tvOS project and created the following code:
- (void)viewDidLoad
{
[super viewDidLoad];
AVPlayer *avPlayer = [AVPlayer playerWithURL:[NSURL URLWithString:#"http://www.myurl.com/myvideo.mp4"]];
AVPlayerLayer *avPlayerLayer = [AVPlayerLayer playerLayerWithPlayer:avPlayer];
avPlayerLayer.frame = CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height);
[self.view.layer addSublayer:avPlayerLayer];
[avPlayer play];
}
Nothing happens in the simulator though once the app loads. No video, nothing, just a blank translucent screen in my Apple TV simulator.
What's the proper way to play a sample video on app launch for an Apple TV app from an HTTP source?
I just pasted your code in my tvOS sample project, replaced the URL and ran it.
Nothing happened. Well, except for the fact that there's a log entry telling me that App Transport Security has blocked my URL request.
So I headed to the Info.plist, disabled ATS and upon next launch the video showed up just fine.
So if you're also using a non-HTTPS URL you're very likely running into this issue which is easily fixed by either using an HTTPS URL, disabling ATS completely or allowing specific non-HTTPs URLs in your Info.plist.
P.S.: I used this video for testing.
You could also use TVML and TVMLJS
https://developer.apple.com/library/prerelease/tvos/documentation/TVMLJS/Reference/TVJSFrameworkReference/
Adhere to the 'TVApplicationControllerDelegate' protocol and add some properties.
AppDelegate.h
#interface AppDelegate : UIResponder <UIApplicationDelegate, TVApplicationControllerDelegate>
...
#property (strong, nonatomic) TVApplicationController *appController;
#property (strong, nonatomic) TVApplicationControllerContext *appControllerContext;
Then add the following to 'didFinishLaunchingWithOptions'
AppDelegate.m
#define url #"http://localhost:8000/main.js"
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.appControllerContext = [[TVApplicationControllerContext alloc] init];
NSURL *javascriptURL = [NSURL URLWithString:url];
self.appControllerContext.javaScriptApplicationURL= javascriptURL;
for (id key in launchOptions) {
id val=[launchOptions objectForKey:key];
NSLog(#"key=%# value=%#", key, val);
if([val isKindOfClass:[NSString class]]) [self.appControllerContext.launchOptions objectForKey:val];
self.appController = [[TVApplicationController alloc] initWithContext:self.appControllerContext window:self.window delegate:self];
}
return YES;
}
create a folder and add the following files
main.js
index.tvml
main.js
function launchPlayer() {
var player = new Player();
var playlist = new Playlist();
var mediaItem = new MediaItem("video", "http://trailers.apple.com/movies/focus_features/9/9-clip_480p.mov");
player.playlist = playlist;
player.playlist.push(mediaItem);
player.present();
//player.play()
}
//in application.js
App.onLaunch = function(options) {
launchPlayer();
}
careful with this url in the mediaItem
Set up a template of your choice.
index.tvml
<document>
<alertTemplate>
<title>…</title>
<description>…</description>
<button>
<text>…</text>
</button>
<text>…</text>
</alertTemplate>
</document>
open terminal and navigate to this folder then run
python -m SimpleHTTPServer 8000
make sure the port here is the port in your ObjC url. The Apple examples use 9001.

One issue I ran into was trying to play a local video file. It wouldn't work and there were constraint issues etc.
It looks like you can't use python to play the videos so either try apache or link to a video on the web.
This SO answer pointed me there.
The best way to play video in your app on AppleTV is going to be AVKit's AVPlayerViewController. If you use AVKit, you get a lot of stuff for free.
https://developer.apple.com/library/ios/documentation/AVFoundation/Reference/AVPlayerViewController_Class/index.html
You simply add that player to the viewController's player property:
// instantiate here or in storyboard
AVPlayerViewController *viewController = [[AVPlayerViewController alloc] initWithNibName:nil bundle:nil];
viewController.player = player;
[self addChildViewController:viewController];
[self.view addSubview:viewController.view];
[viewController didMoveToParentViewController:self];
// setup constraints, etc.
// play the video
[player play];
Also as mentioned below, make sure the video you're trying to play is coming either from an HTTPS connection or that you've disabled App Transport Security by setting the proper flags in the plist.
I didn't like the answers which messed about with subviews etc.
For full-screen playback, I use the following (Non-ARC) code:
// Play the stream
NSString *wifiStreamAddress = #"http://yourmoviefile.m3u8";
AVPlayer *player = [[AVPlayer alloc] initWithURL: [NSURL URLWithString: wifiStreamAddress] ];
AVPlayerViewController *playerViewController = [[AVPlayerViewController alloc] init];
playerViewController.player = player;
// Keep pointers to player and controller using retained properties:
self.player = player;
self.playerViewController = playerViewController;
[player release];
[playerViewController release];
[self presentViewController: playerViewController animated: true completion: ^{
[self.player play];
}];
This works really neat, animating presentation and fading back to previous view when you tap the MENU button. Also, it works great with the remote control using all the standard functions.
Its working for me.
May be helpful for you
-(void)playAction
{
AVPlayerViewController *viewController = [[AVPlayerViewController alloc] initWithNibName:nil bundle:nil];
viewController.player = player;
[self addChildViewController:viewController];
[self.view addSubview:viewController.view];
[viewController didMoveToParentViewController:self];
// play the video
[player play];
}
Swift version
Make a PlayViewController which inherit the AVPlayerViewController.
In the viewcontroller which has play button, add such function
#IBAction func onClickPlay(sender: AnyObject) {
let playerVC = PlayerViewController()
playerVC.playVideo(urlString)
[self.presentViewController(playerVC, animated: true, completion: nil)]
}
In the PlayerViewController
func playVimeoVideo(link : String) {
player = AVPlayer(URL: NSURL(string: link)!)
player?.play()
}
Notice
The question and some answers may be a little misleading so that you might think that only the url with ".mp4" at the end can be played by the Apple TV. I believed so at the first time I saw the post. It is not true. In fact, with AVPlayerViewController you can play Vimeo streaming video! The link to the stream video is not like https://vimeo.com/92655878. It is possible to get it from Vimeo site by extracting it from a json file, which can be downloaded from this link
let link = "https://vimeo.com/api/oembed.json?url=https%3A//vimeo.com/" + videoId
To be able to get correct url for the video, you need to use the Vimeo Pro user access to get the stream link for a specific video.
I added UIScreen bounds code in AppDelegate.m for iPhone 6 and now device orientation for iPhone 6 won't work for Portrait/ Upside Down. Upside Down is what's not working in simulator and devices.
Code in AppDelegate.m
CGSize iosScreenSize = [[UIScreen mainScreen] bounds].size;
if (iosScreenSize.height == 667) {
UIStoryboard *iPhone6 = [UIStoryboard storyboardWithName:#"iPhone6" bundle:nil];
UIViewController *initialViewController =[iPhone6 instantiateInitialViewController];
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen]bounds]];
self.window.rootViewController = initialViewController;
[self.window makeKeyAndVisible];
}
When I included the above code the simulator and device for iPhone 6 doesn't detect Upside Down orientation. I also used nativeBounds and screenBounds, didn't work either for Upside Down orientation.
My code for device orientation...
-(NSUInteger)supportedInterfaceOrientations {
return (UIInterfaceOrientationMaskPortrait | UIInterfaceOrientationMaskPortraitUpsideDown);
}
I have no idea what to do to get AppDelegate code to let UpSide Down orientation be detected for iPhone 6.
OK, finally figured this one out.
Then realized someone posted the answer here: Setting device orientation in Swift iOS
Go down to DaRk-_-D0G's answer.
I had to subclass my tab bar controller just to override that method. Very obnoxious .
In iOS 8 in my app when I changed the orientation of device at that time UIAlertview also get changed to respective Orientation.I want to restrict it.I want alertview fixed to be in Portrait mode.
In iOS8,system provide a new class UIAlertController replay UIAlertView and UIActionSheet，This is a FYAlertView that support iOS8 and iOS8 before use UIALertView and UIActionSheet https://github.com/wangyangcc/FYAlertManage
You can use this code it may help you .
- (void)didPresentAlertView:(UIAlertView *)alertView
{
[UIView beginAnimations:#"" context:nil];
[UIView setAnimationDuration:0.1];
alertView.transform = CGAffineTransformRotate(alertView.transform, degreesToRadian(90));
[UIView commitAnimations];
}
I'd like to know how to make the mute and unmute the audio on my iPad application by tapping a button. I already have a working code in my viewDidLoad method that plays a music when the app is launched. All I need to do is to create a button that will stop the music from playing and also resume it when tapped again.
Here's my code in my viewDidLoad:
- (void)viewDidLoad
{
NSString *path = [[NSBundle mainBundle] pathForResource:#"Bored" ofType:#"mp3"];
AVAudioPlayer* theAudio = [[AVAudioPlayer alloc]initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL];
theAudio.delegate = self;
[theAudio play];
[super viewDidLoad];
}
Just look at the AVAudioPlayer API - it's all there: play, pause, volume, etc.
