視頻播放

• 1> AVPlayer
  能播放本地、遠(yuǎn)程的音頻、視頻文件
  基于Layer顯示，得自己去編寫控制面板

• 2> MPMoviePlayerController
  能播放本地、遠(yuǎn)程的音頻、視頻文件
  自帶播放控制面板（暫停、播放、播放進(jìn)度、是否要全屏）

• 3> MPMoviePlayerViewController
  能播放本地、遠(yuǎn)程的音頻、視頻文件
  內(nèi)部是封裝了MPMoviePlayerController
  播放界面默認(rèn)就是全屏的
  如果播放功能比較簡(jiǎn)單，僅僅是簡(jiǎn)單地播放遠(yuǎn)程、本地的視頻文件，建議用這個(gè)

區(qū)別

1.AVPlayer(遠(yuǎn)程?音樂(lè)/播放視頻)—>添加layer

2.MPMoviePlayerController—>給.view設(shè)置frame,將這個(gè)view 添加到某?一個(gè)View

3.MPMoviePlayerViewController(modal出來(lái),?自動(dòng)播放,?一定全 屏播放)

1:AVPlayer

• 可以播放遠(yuǎn)程視頻(需要通過(guò)添加layer來(lái)顯示視頻)
