detect AVPlayerViewController Done button click? - ios

Question

I'm writing Plugin for AVPlayer in ios. I need to know when user click on Done button in AVPlayerViewController ( I want to know when user close video) and I don't access to AVPlayerViewController object. I checked event and found only rate property in AVPlayer set to 0 but in pause situation also the rate set to 0 . how I figure out these two situations ?
thanks all.

I met the problem when I was developing the player in windowed mode. It is currently impossible without tricks. Therefore, I used KVO to observe contentOverlayView which is actually a full-size view of AVPlayerViewController. Code is a bit complicated. In the example below, playerView property is a view from xib/storyboard on the view controller (see attached).
#import <AVKit/AVKit.h>
#import <AVFoundation/AVFoundation.h>
static NSString * const kBoundsProperty = #"bounds";
static void * kBoundsContext = &kBoundsContext;
#interface ViewController ()
#property (nonatomic, strong) AVPlayerViewController *playerViewController;
// View for windowed mode.
#property (weak, nonatomic) IBOutlet UIView *playerView;
#end
#implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
self.playerViewController = [[AVPlayerViewController alloc] init];
}
- (void)viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];
// Because in -viewDidLoad frame is unknown.
[self loadPlayerView];
}
- (void)loadPlayerView {
NSURL *videoURL = [NSURL URLWithString:#"https://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4"];
AVPlayer *player = [[AVPlayer alloc] initWithURL:videoURL];
self.playerViewController.player = player;
[player play];
[self addChildViewController:self.playerViewController];
[self.playerView addSubview:self.playerViewController.view];
// MARK: I would recommend to use constraints instead of frame.
self.playerViewController.view.frame = self.playerView.bounds;
[self.playerViewController.contentOverlayView addObserver:self forKeyPath:kBoundsProperty options:NSKeyValueObservingOptionNew | NSKeyValueObservingOptionOld context:kBoundsContext];
}
- (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary<NSString *,id> *)change context:(void *)context {
if (context == kBoundsContext) {
CGRect oldBounds = [change[NSKeyValueChangeOldKey] CGRectValue];
CGRect newBounds = [change[NSKeyValueChangeNewKey] CGRectValue];
BOOL wasFullscreen = CGRectEqualToRect(oldBounds, [UIScreen mainScreen].bounds);
BOOL isFullscreen = CGRectEqualToRect(newBounds, [UIScreen mainScreen].bounds);
if (isFullscreen && !wasFullscreen) {
if (CGRectEqualToRect(oldBounds, CGRectMake(0.0, 0.0, newBounds.size.height, newBounds.size.width))) {
NSLog(#"Rotated fullscreen");
} else {
NSLog(#"Entered fullscreen");
dispatch_async(dispatch_get_main_queue(), ^{
[[NSNotificationCenter defaultCenter] postNotificationName:#"DidEnterInFullscreen" object:nil];
});
}
} else if (!isFullscreen && wasFullscreen) {
NSLog(#"Exited fullscreen");
dispatch_async(dispatch_get_main_queue(), ^{
[[NSNotificationCenter defaultCenter] postNotificationName:#"DidExitFromFullscreen" object:nil];
});
}
}
}
#end
