AVPlayerViewController with custom overlay - objective-c

Question

Migrating to AVkit from MPMoviePlayer has brought me to a blocking issue.
I need to display a custom tableView over the AVPlayerViewController.
I can this tableview trough
[self.avVideoPlayer.contentOverlayView addsubiew:self.mycustomTableView]
and it is visible but it doesn't receive any tap/swipe events.
Any ideas why this happens or how can I add the table view in a place where it would receive the touch events even in the fullscreen mode?

Answer 1

[self.view addSubview:btn];
This will add the button in the minimised player.
Now for the fullscreen scenario you need to add an observer for the videoBounds, here is my code:
[self.avVideoPlayer addObserver:self forKeyPath:#"videoBounds" options:NSKeyValueObservingOptionNew | NSKeyValueObservingOptionOld context:NULL];
Now here comes the not so pretty part:
- (void)observeValueForKeyPath: (NSString*) path
ofObject: (id)object
change: (NSDictionary*)change
context: (void*)context {
NSLog(#"SOME OBSERVER DID THIS: %# , %#",object,change);
if ([self playerIsFullscreen]) {
for(UIWindow* tempWindow in [[UIApplication sharedApplication]windows]){
for(UIView* tempView in [tempWindow subviews]){
if ([[tempView description] rangeOfString:#"UIInputSetContainerView"].location != NSNotFound){
UIButton *testB = [[UIButton alloc] initWithFrame: CGRectMake(20, 20, 400, 400)];
testB.backgroundColor = [UIColor redColor];
[testB addTarget:self action:#selector(buttonTouch) forControlEvents:UIControlEventTouchDown];
[tempView addSubview:testB];
break;
}
}
}
}
}
I know this is a not a nice way to do it, but it is the only way I managed to add some custom UI that also receives touch events on the player.
Cheers!
