swift--歌曲播放示例

使用MPMoviePlayerController我们可以是进行音乐播放，如下图：

接口的话，我是自己在本地上搭建了个服务器，自己请求自己

就是用这个神器，获得一个音频文件的地址！

具体代码如下：

import UIKit
import MediaPlayer

class SixteenthViewController: UIViewController,httpTools {
    
    //获取网络数据类
    var hHttp = HttpController()
    //接受频道列表的数组
    var channelData:[AnyObject] = Array()
    
    //隐藏tabbar
    override func viewWillAppear(_ animated: Bool) {
        navigationController?.tabBarController?.tabBar.isHidden = true
    }
    
    override func viewWillDisappear(_ animated: Bool) {
        navigationController?.tabBarController?.tabBar.isHidden = true
    }
    let imageV = UIImageView()
    let myView = UIView()
    
    //声明一个媒体播放控件
    var audioPlayer = MPMoviePlayerController()
    //声明一个计时器
    var timer:Timer?
    var label:UILabel?
    var progressV:UIProgressView?
    override func viewDidLoad() {
        super.viewDidLoad()
        self.view.backgroundColor = UIColor.white
        // Do any additional setup after loading the view.
　　　　
　　　　　　self.creatPlayer()

        }
    func creatPlayer() {
        progressV = UIProgressView(frame:CGRect(x:20,y:350,width:kScreenWidth-40,height:20))
        self.view.addSubview(progressV!)
        
        label = UILabel(frame:CGRect(x:40,y:385,width:kScreenWidth-80,height:45))
        label?.textColor = UIColor.black
        self.view.addSubview(label!)
        
        self.setOnAudio(url: "http://192.168.0.137:809/Yes,%20I%20Love%20You_Aaron%20Neville_...To%20Make%20Me%20Who%20I%20Am.mp3")
    }
    
    //播放歌曲
    func setOnAudio(url:String){
        //暂停当前歌曲的播放
        self.audioPlayer.stop()
        //获取歌曲文件
        self.audioPlayer.contentURL = URL(string:url)
        //播放歌曲
        self.audioPlayer.play()
        //先停掉计时器
        timer?.invalidate()
        //将计时器归零
        label?.text = "00:00"
        //开启计时器
        timer = Timer.scheduledTimer(timeInterval: 0.4, target: self, selector: #selector(onUpdate), userInfo: nil, repeats: true)
    }
    
    func onUpdate() {
        //返回播放器当前的播放时间
        let c = audioPlayer.currentPlaybackTime
        if c > 0.0 {
            //歌曲的总时间
            let t = audioPlayer.duration
            print("播放的总时间是:\(t)")
            //歌曲播放的百分比
            let p:CGFloat = CGFloat(c/t)
            //通过百分比设置进度条
            progressV?.setProgress(Float(p), animated: true)
            //一个小算法，来实现00：00这种格式的播放时间
            let all:Int=Int(c)
            let m:Int=all % 60
            let f:Int=Int(all/60)
            print("时间：\(f)--\(m)")
            var time:String=""
            if f<10{
                time="0\(f):"
            }else {
                time="\(f)"
            }
            if m<10{
                time+="0\(m)"
            }else {
                time+="\(m)"
            }
            
            //更新播放时间
            label?.text = time
        }
        
    }
    
    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }
    

    /*
    // MARK: - Navigation

    // In a storyboard-based application, you will often want to do a little preparation before navigation
    override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
        // Get the new view controller using segue.destinationViewController.
        // Pass the selected object to the new view controller.
    }
    */

}

仅做记录！
