Playing video in Landscape and portrait - ios

Question

I have my app in portrait mode.
When video player enters full screen mode, I want to play that video in both landscape and portrait orientation.
moviePlayer = [[MPMoviePlayerController alloc]initWithContentURL:url];
[moviePlayer.view setAutoresizingMask:(UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleWidth)];
[moviePlayer setScalingMode:MPMovieScalingModeFill];
moviePlayer.view.frame = CGRectMake(0, 0, self.videoPlayerView.frame.size.width, self.videoPlayerView.frame.size.height);
[self.videoPlayerView addSubview:moviePlayer.view];
and I am playing it on one button.

Enable your Landscape Device Orientation in Deployment Info. Then, add these methods in your ViewController:
- (BOOL) shouldAutorotate {
return NO;
}
- (NSUInteger) supportedInterfaceOrientations {
return UIInterfaceOrientationMaskPortrait;
}
- (UIInterfaceOrientation) preferredInterfaceOrientationForPresentation {
return UIInterfaceOrientationPortrait;
}

Try to add a canvas view as superview to your player and apply transformation to the canvas view.
- (void)initialize{
self.canvas = [[UIView alloc] initWithFrame: self.view.bounds];
[self.view addSubview:self.canvas];
// init moviePlayer
moviePlayer = [[MPMoviePlayerController alloc]initWithContentURL:url];
...
[self.canvas addSubview: moviePlayer.view];
// Add observers
...
[[NSNotificationCenter defaultCenter] addObserver: self
selector: #selector(deviceOrientationDidChange)
name: UIDeviceOrientationDidChangeNotification
object: nil];
[[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
}
- (void)deviceOrientationDidChange{
// Apply rotation only in full screen mode
if (self.isFullScreen) {
UIDeviceOrientation currentOrientation = [UIDevice currentDevice].orientation;
[UIView animateWithDuration: 0.3
animations: ^{
CGAffineTransform transform = CGAffineTransformMakeRotation(0);
switch (orientation) {
case UIDeviceOrientationLandscapeLeft:
transform = CGAffineTransformMakeRotation(M_PI_2);
break;
case UIDeviceOrientationLandscapeRight:
transform = CGAffineTransformMakeRotation(M_PI + M_PI_2);
break;
default:
break;
};
self.canvas.transform = transform;
self.canvas.frame = self.canvas.superview.bounds;
}];
}
}
