口吃和音轨开始播放多次

Question

在使用 Spotify 播放器时，我们偶尔会遇到持续大约 10 秒的口吃。虽然有几个方面对我来说似乎不正常，但最一致的迹象是，我们不止一次地点击了didStartPlayingTrack 委托方法，即使我们只告诉玩家玩一次。有没有人知道什么会导致这种情况发生？

重要提示：这是spotify-ios-sdk version 0.21

日志样本：

audioStreaming(_:didReceive:withName:)[L:412]: didReceiveEvent: Optional("SPPlaybackNotifyTrackDelivered") // Last track ended
audioStreaming(_:didReceive:withName:)[L:412]: didReceiveEvent: Optional("SPPlaybackNotifyAudioDeliveryDone")
audioStreaming(_:didReceive:withName:)[L:412]: didReceiveEvent: Optional("SPPlaybackNotifyPause")
audioStreaming(_:didReceive:withName:)[L:412]: didReceiveEvent: Optional("SPPlaybackNotifyMetadataChanged")
movePlayerPosition(_:completion:)[L:180]: seek successful to 0.842
audioStreaming(_:didReceive:withName:)[L:412]: didReceiveEvent: Optional("SPPlaybackNotifyMetadataChanged")
13:13:50 audioStreaming(_:didStartPlayingTrack:)[L:377]: didStartPlayingTrack: Optional("So Far Away (Live) - Live")
audioStreaming(_:didReceive:withName:)[L:412]: didReceiveEvent: Optional("SPPlaybackNotifyTrackChanged")
audioStreaming(_:didReceive:withName:)[L:412]: didReceiveEvent: Optional("SPPlaybackEventAudioFlush")
audioStreaming(_:didReceive:withName:)[L:412]: didReceiveEvent: Optional("SPPlaybackNotifyPlay")
audioStreaming(_:didReceive:withName:)[L:412]: didReceiveEvent: Optional("SPPlaybackNotifyMetadataChanged")
audioStreaming(_:didReceive:withName:)[L:412]: didReceiveEvent: Optional("SPPlaybackNotifyMetadataChanged")
audioStreaming(_:didReceive:withName:)[L:412]: didReceiveEvent: Optional("SPPlaybackNotifyContextChanged")
13:14:01 audioStreaming(_:didStartPlayingTrack:)[L:377]: didStartPlayingTrack: Optional("So Far Away (Live) - Live")
audioStreaming(_:didReceive:withName:)[L:412]: didReceiveEvent: Optional("SPPlaybackNotifyTrackChanged")
audioStreaming(_:didSeekToPosition:)[L:474]: did seek to position: 0.001
audioStreaming(_:didReceive:withName:)[L:412]: didReceiveEvent: Optional("SPPlaybackEventAudioFlush")

有没有办法防止这种口吃的发生？

更新

我已切换到版本 25，但仍然遇到此问题。我发现的口吃日志中一个明显的特征是，在大多数歌曲的开头，除非特别要求，否则我没有得到didSeekToPosition 代表；但是，当遇到口吃时，我会在口吃开始时看到以下内容：

audioStreaming(_:didStartPlayingTrack:)[L:377]: didStartPlayingTrack
audioStreaming(_:didSeekToPosition:)[L:474]: did seek to position: 0.001

需要明确的是，只有一种方法调用playSpotifyUri；但是，这个 didStartPlaying 代表会被多次命中。

iOS SDK 现在是 Beta 25 版本，您是否考虑过升级？我建议这样做，看看它是否能解决您的问题。

我需要查看您的具体实现才能进行调试。
