StreamingKit是一个适用于iOS和Mac OSX的音频播放流媒体库。提供了一个简洁的面向对象API，简单易用,用于在CoreAudio框架下进行音频的解压和播放处理。StreamingKit是唯一支持不同格式音频文件无缝播放的音频播放流媒体库。github地址:https://github.com/tumtumtum/StreamingKit
简单的介绍一下使用:
定义STKAudioPlayer属性audioPlayer 并在viewDidLoad中初始化,设置代理.
audioPlayer = STKAudioPlayer()
audioPlayer.delegate = self
播放暂停按钮的点击事件:
dynamic func playOrPause(sender:UIButton){
//1.开启播放
//2.暂停播放
//3.继续播放
//4.重新播放
if firstPlay == true { //1、4
let urll = NSURL(string: musicModel.videoUrl)
if let musicPlayUrl = urll{
audioPlayer.playURL(musicPlayUrl)
print("__________这是音频播放的url_______\(musicPlayUrl)__________")
}
//设置定时器显示进度
timer = NSTimer(timeInterval: 0.1, target: self, selector: #selector(track), userInfo: nil, repeats: true)
// timer.fire()
NSRunLoop.currentRunLoop().addTimer(timer, forMode: NSRunLoopCommonModes)
//后台控制面板信息
newMusicInfo()
self.firstPlay = false
}else{
if self.audioPlayer.state.rawValue == 3{
//暂停
audioPlayer.pause()
}else{
//继续
audioPlayer.resume()
}
}
}
定时器方法:(自定义部分可忽略不看,大致就是实时获取音乐当前的播放时间与总时间并赋值给界面)
dynamic func track(){
// print("******总时间********\(self.audioPlayer.duration)++++++")
// print("******播放进度********\(self.audioPlayer.progress)++++++")
let formatter = NSDateFormatter()
formatter.dateFormat = "mm:ss"
let elapsedTimeDate = NSDate(timeIntervalSince1970: audioPlayer.progress)
self.musicPlayerView.currentLabel.text = formatter.stringFromDate(elapsedTimeDate)
let timeRemainingDate = NSDate(timeIntervalSince1970: audioPlayer.duration)
self.musicPlayerView.totalLabel.text = formatter.stringFromDate(timeRemainingDate)
self.musicPlayerView.progressSlider.value = Float(audioPlayer.progress)
self.musicPlayerView.progressSlider.maximumValue = Float(audioPlayer.duration)
if audioPlayer.progress == audioPlayer.duration-0.01{
audioPlayer.stop()
self.musicPlayerView.currentLabel.text = "00:00"
self.musicPlayerView.totalLabel.text = "00:00"
self.musicPlayerView.progressSlider.value = 0
self.firstPlay = true
}
}
底部进度条(自定义UISlider)拖动实现的方法:[逻辑是先暂停,再通过seekToTime方法到指定进度,然后继续]
dynamic func sliderDown(slider:UISlider){
audioPlayer.pause()
}
dynamic func sliderTouchUpInside(slider:UISlider){
print("+++++拖动值+++++\(Double(slider.value))+++")
audioPlayer.seekToTime(Double(slider.value))
audioPlayer.resume()
}
最后罗列一下必须实现的代理STKAudioPlayerDelegate
extension MusicDetailViewController: STKAudioPlayerDelegate {
dynamic func audioPlayer(audioPlayer: STKAudioPlayer, didStartPlayingQueueItemId queueItemId: NSObject) {
}
//typedef NS_OPTIONS(NSInteger, STKAudioPlayerState)
//{
// STKAudioPlayerStateReady,
//STKAudioPlayerStateRunning = 1,
//STKAudioPlayerStatePlaying = (1 << 1) | STKAudioPlayerStateRunning,
//STKAudioPlayerStateBuffering = (1 << 2) | STKAudioPlayerStateRunning,
//STKAudioPlayerStatePaused = (1 << 3) | STKAudioPlayerStateRunning,
//STKAudioPlayerStateStopped = (1 << 4),
//STKAudioPlayerStateError = (1 << 5),
//STKAudioPlayerStateDisposed = (1 << 6)
//};
dynamic func audioPlayer(audioPlayer: STKAudioPlayer, stateChanged state: STKAudioPlayerState, previousState: STKAudioPlayerState) {
switch state.rawValue {
case 3 : musicPlayerView.startPlayerBtn.selected = true
case 5: musicPlayerView.startPlayerBtn.selected = false
case 6: musicPlayerView.startPlayerBtn.selected = false
case 7: musicPlayerView.startPlayerBtn.selected = false
default: musicPlayerView.startPlayerBtn.selected = false
}
}
dynamic func audioPlayer(audioPlayer: STKAudioPlayer, didFinishBufferingSourceWithQueueItemId queueItemId: NSObject) {
}
dynamic func audioPlayer(audioPlayer: STKAudioPlayer, unexpectedError errorCode: STKAudioPlayerErrorCode) {
}
dynamic func audioPlayer(audioPlayer: STKAudioPlayer, didFinishPlayingQueueItemId queueItemId: NSObject, withReason stopReason: STKAudioPlayerStopReason, andProgress progress: Double, andDuration duration: Double) {
}
}
