在Swift Playground中使用AVPlayer播放视频？

我在使用AVPlayer在快速游乐场内播放视频时遇到问题.

这是我的代码.

import UIKit
import AVFoundation

var f=CGRectMake(0, 0, 500, 500)
var url=NSURL(string: "http://s3.amazonaws.com/vids4project/sample.mp4")
var playerItem = AVPlayerItem(URL: url)

var v = UIView(frame:f)
var player=AVPlayer(playerItem: playerItem)
var playerLayer=AVPlayerLayer(player: player)

playerLayer.frame=f
v.layer.addSublayer(playerLayer)
player.play()

有什么建议？代码完全没有任何作用.我的期望是'v'变量应该显示视频.当我将avplayerlayer连接到故事板的视图时,它似乎在操场外工作.

如果将它放入操场,以下情况应该有效.确保换出路径:(Xcode7 GM)

import UIKit
import AVFoundation
import XCPlayground


var f = CGRectMake(0, 0, 500, 500)

let path = NSBundle.mainBundle().pathForResource("movie", ofType: "m4v")!
let url = NSURL(fileURLWithPath: path)

var playerItem = AVPlayerItem(URL: url)

var v = UIView(frame: f)
v.backgroundColor = UIColor.blackColor()
var player = AVPlayer(playerItem: playerItem)
var playerLayer = AVPlayerLayer(player: player)

playerLayer.frame = f
v.layer.addSublayer(playerLayer)
player.play()

XCPShowView("View", view: v)

尝试在最后添加这个以保持游乐场运行

import XCPlayground
XCPSetExecutionShouldContinueIndefinitely(continueIndefinitely: true)
