如何在 iOS 锁屏上添加搜索按钮？

Question

如何设置 MPRemoteCommandCenter/MPNowPlayingInfoCenter 来添加搜索按钮？我想要实现的结果在屏幕截图上。 我已经添加了这段代码：

[[MPRemoteCommandCenter sharedCommandCenter].seekForwardCommand addTargetWithHandler:^MPRemoteCommandHandlerStatus(MPRemoteCommandEvent * _Nonnull event) {
    [weakSelf rewindForward];

    return MPRemoteCommandHandlerStatusSuccess;
}];
[MPRemoteCommandCenter sharedCommandCenter].seekForwardCommand.enabled = YES;

[[MPRemoteCommandCenter sharedCommandCenter].seekBackwardCommand addTargetWithHandler:^MPRemoteCommandHandlerStatus(MPRemoteCommandEvent * _Nonnull event) {
    [weakSelf rewindBackward];

    return MPRemoteCommandHandlerStatusSuccess;
}];
[MPRemoteCommandCenter sharedCommandCenter].seekBackwardCommand.enabled = YES;
