这节我们主要讲UITapGestureRecognizer和MPMoviePlayerController

知识点

UITapGestureRecognizer

关联storyboard上的UITapGestureRecognizer

@IBOutlet var tap:UITapGestureRecognizer=nil  //注意要设置为nil

增加手势识别

addGestureRecognizer(tap)

移除手势识别

removeGestureRecognizer(tap)

关联Action

@IBAction func onTap(recognizer: UITapGestureRecognizer)

通过recognizer.view可以判断点击了哪个组件

@IBAction func onTap(recognizer: UITapGestureRecognizer){

        if recognizer.view==btnPlay {

            btnPlay.hidden=true

            audioPlayer.play()

            btnPlay.removeGestureRecognizer(tap)

            iv.addGestureRecognizer(tap)

        }else if recognizer.view==iv {

            btnPlay.hidden=false

            audioPlayer.pause()

            btnPlay.addGestureRecognizer(tap)

            iv.removeGestureRecognizer(tap)

        }

}

MPMoviePlayerController
