ios - MPMovieViewController 下一个/上一个按钮事件

Question

我是 Swift 新手我正在使用 MPMovieviewcontroller当我单击下一个或上一个按钮时，没有事件发生这是代码

import UIKit
import MediaPlayer
class ViewController: UIViewController {
var i : Int = 0

var movieplayer : MPMoviePlayerController!

var arr = ["Akbar","Serial","ak"]
override func viewDidLoad() {
    super.viewDidLoad()

    UIApplication.sharedApplication().beginReceivingRemoteControlEvents()
    self.becomeFirstResponder()
    startplaying()

}

override func canBecomeFirstResponder() -> Bool {
    return true
}
override func remoteControlReceivedWithEvent(event: UIEvent) {
    if event.subtype == UIEventSubtype.RemoteControlNextTrack
    {
        i++
        startplaying()
      println(event.subtype)
    }
}
func startplaying()
{
 if i <= 2
 {
 let path = NSBundle.mainBundle().pathForResource(arr[i], ofType: "mov")
let url = NSURL.fileURLWithPath(path!)

movieplayer = MPMoviePlayerController(contentURL: url)
}

movieplayer.view.frame = CGRect(x: 0, y: 0, width: self.view.frame.size.width, height: self.view.frame.size.height)
movieplayer.view.sizeToFit()

movieplayer.scalingMode = MPMovieScalingMode.AspectFill
movieplayer.fullscreen = true

movieplayer.controlStyle = MPMovieControlStyle.Fullscreen

movieplayer.movieSourceType = MPMovieSourceType.File
movieplayer.prepareToPlay()

self.view.addSubview(movieplayer.view)
}

当我调试这段代码时，remoteControlReceivedWithEvent 函数没有执行

我从here获得donm帮助

Answer 1

试试这个

func startplaying() {
    if i <= 2 {
        let path = NSBundle.mainBundle().pathForResource(arr[i], ofType: "mov")
        let url = NSURL.fileURLWithPath(path!)
    movieplayer.contentURL = NSURL.fileURLWithPath(url)
}
