nextTrackCommand和seekForwardCommand都同时被调用

Question

似乎当我在播放某些东西（模拟器或设备）时在控制中心上按“下一个”时，nextTrackCommand和seekForwardCommand都被调用。

这两个功能都已启用，但是只要轻按“下一步”按钮就不会调用这两个功能。

更多代码：

[MPRemoteCommandCenter sharedCommandCenter].playCommand.enabled = YES;
[[MPRemoteCommandCenter sharedCommandCenter].playCommand addTargetWithHandler:^MPRemoteCommandHandlerStatus(MPRemoteCommandEvent * _Nonnull event) {
    return MPRemoteCommandHandlerStatusSuccess;
}];

[[MPRemoteCommandCenter sharedCommandCenter].nextTrackCommand addTargetWithHandler:^MPRemoteCommandHandlerStatus(MPRemoteCommandEvent * _Nonnull event) {
    NSLog(@"nextTrackCommand");
    return MPRemoteCommandHandlerStatusSuccess;
}];
[MPRemoteCommandCenter sharedCommandCenter].nextTrackCommand.enabled = YES;

[[MPRemoteCommandCenter sharedCommandCenter].seekForwardCommand addTargetWithHandler:^MPRemoteCommandHandlerStatus(MPRemoteCommandEvent * _Nonnull event) {
    NSLog(@"seekForwardCommand");
    return MPRemoteCommandHandlerStatusSuccess;
}];
[MPRemoteCommandCenter sharedCommandCenter].seekForwardCommand.enabled = YES;

我已将波纹管链接到一个演示此问题的示例项目。
