ios - 卡顿和轨道开始多次播放

Question

在使用 Spotify 播放器时，我们偶尔会遇到持续大约 10 秒的卡顿。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(delegate)方法，即使我们只告诉玩家玩一次。有谁知道什么会导致这种情况发生？

重要提示:这是 spotify-ios-sdk 版本 0.21

日志示例:

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")

有什么办法可以防止这种口吃的发生吗？

更新

我已经切换到版本 25，但我仍然遇到这个问题。我在口吃日志中发现的一个显着特征是，在大多数歌曲开始时，除非特别要求，否则我不会得到 didSeekToPosition 委托(delegate)；但是，当遇到口吃时，口吃开始时我会看到以下内容:

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

明确一点，只有一种方法调用playSpotifyUri；然而，这个 didStartPlaying 委托(delegate)被多次命中。

Answer 1

iOS SDK 现在是 Beta 25 版本，你考虑过升级吗？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以便进行调试。
