用于检测全屏或视频大小改变你可以使用KVO作为AVPlayerViewController,代码可以是这样的:
For the detecting the Full screen or video size change you can use KVO for the AVPlayerViewController, code can be like this:
[comPlayerControl .addObserver(self, forKeyPath:"videoBounds" , options: NSKeyValueObservingOptions.New, context: nil)]
override func observeValueForKeyPath(keyPath: String?, ofObject object: AnyObject?, change: [String : AnyObject]?, context: UnsafeMutablePointer<Void>) {
print("KeyPath \(keyPath)")
if keyPath == "videoBounds" {
print("New Video Bounds \(change)")
}
}
在更改
字典你可以检查视频帧/边界变化的变化
In the change
dictionary you can check the change in the video frame/bounds change
对于你提到的轮换你可能不得不使用 viewWillTransitionToSize
或 UIDeviceOrientationDidChangeNotification
通知或您可以使用 UIDevice.currentDevice()检查当前方向。orientation
因为我没有找到任何可以检查正在进行的视频中的更改的方法
For the rotation as you mentioned you may have to use viewWillTransitionToSize
or UIDeviceOrientationDidChangeNotification
notification or you can check the current orientation using UIDevice.currentDevice().orientation
as i didn't find any method which can check the change in the ongoing video

要重复播放视频,您可以在代码中将时间设置为零:
For the repeat of the video you can set the time to zero like this in your code:
func playerDidFinishPlaying(notification: NSNotification) {
if let item = notification.object as? AVPlayerItem {
item.seekToTime(kCMTimeZero)
//you may directly play the video or can do further processing
}
}
在项目结尾处播放队列中的项目,您可以尝试使用 commmentQueuePlayer.advanceToNextItem()
to play item in the queue at the end of the item you may try with commmentQueuePlayer.advanceToNextItem()
您可以尝试在 contentOverlayView
let topView = UIView(frame: CGRectMake(0,0, comPlayerControl.view.bounds.width,44))
topView.backgroundColor = UIColor ( red: 0.5, green: 0.5, blue: 0.5, alpha: 0.379 )
let btnNext = UIButton(frame:CGRectMake(0,0,80,44))
btnNext.setTitle("Next", forState:.Normal)
btnNext.addTarget(self, action:"playNext", forControlEvents:.TouchUpInside)
btnNext.userInteractionEnabled = true
btnNext.enabled = true
topView.addSubview(btnNext)
comPlayerControl.contentOverlayView?.addSubview(topView)
更新
对于 observeValueForKeyPath
,您可以尝试这样的事情
For the observeValueForKeyPath
you may try something like this
var avWidth:CGFloat = 0
var avHeight:CGFloat = 0
override func observeValueForKeyPath(keyPath: String?, ofObject object: AnyObject?, change: [String : AnyObject]?, context: UnsafeMutablePointer<Void>) {
if keyPath == "videoBounds" {
let rect = change!["new"]! as! NSValue
if let newrect = rect.CGRectValue() as CGRect? {
if newrect.width > 0 || newrect.height > 0 {
if avWidth > 0 || avHeight > 0 {
if newrect.width > avWidth || newrect.height > avHeight {
print("Full Screen")
} else if newrect.width < avWidth || newrect.height < avHeight {
print("Normal screen")
} else {
}
}
avWidth = newrect.width
avHeight = newrect.height
}
}
}
}
