如何在iOS Lock Screen控制面板中启用音频滑块？ [英] How to enable audio scrubber in iOS Lock Screen control panel?

问题描述

我有以下字典用于MPNowPlayingInfoCenter

I have the following dictionary for MPNowPlayingInfoCenter

@{MPMediaItemPropertyAlbumTitle: @"First Title",
                                MPMediaItemPropertyArtwork: [[MPMediaItemArtwork alloc] initWithImage:[UIImage imageNamed:@"Album-Cover.jpg"]],
                                MPMediaItemPropertyPlaybackDuration:[NSNumber numberWithDouble:self.storyAudioPlayer.duration],
                                MPNowPlayingInfoPropertyElapsedPlaybackTime:[NSNumber numberWithDouble:self.storyAudioPlayer.currentTime],
                                MPNowPlayingInfoPropertyPlaybackRate:@1.0
                                }

其他工作正常，但我无法使用滑块寻找歌曲。如图所示。我错过了什么参数？

Everything else is working fine but I can't seek songs using the slider. As shown in the image. What parameter am I missing?

推荐答案

你做不到。您可以向Apple提交错误报告，以便他们有一天能够实现它。

You can't. You could file a bug report to Apple so that they implement it someday.

编辑：现在可以从iOS 9开始了

It's now possible to do it since iOS 9
