我尝试控制用户可以在歌曲播放中提前几秒。我管理的只是用户可以看到播放头而不与它互动。
我在AVAudioSessionCategoryPlayback模式下使用AVAudioSession。 AVPlayer和AVPlayerItem
_playerItem = [AVPlayerItem playerItemWithURL:url];
_player = [AVPlayer playerWithPlayerItem:self.playerItem];
[编辑]这样,我控制了远程事件:
- (void)remoteControlReceivedWithEvent:(UIEvent *)event {
//if it is a remote control event handle it correctly
if (event.type == UIEventTypeRemoteControl)
{
if (event.subtype == UIEventSubtypeRemoteControlPlay) {
NSLog(@"Responds nice to the event UIEventSubtypeRemoteControlPlay");
} else if (event.subtype == UIEventSubtypeRemoteControlPause) {
NSLog(@"Responds nice to the event UIEventSubtypeRemoteControlPause");
} else if (event.subtype == UIEventSubtypeRemoteControlTogglePlayPause) {
NSLog(@"Responds nice to the event UIEventSubtypeRemoteControlTogglePlayPause");
} else if (event.subtype == UIEventSubtypeRemoteControlBeginSeekingBackward) {
NSLog(@"NEVER Responds!!!");
} else if (event.subtype == UIEventSubtypeRemoteControlBeginSeekingForward) {
NSLog(@"NEVER Responds!!!");
} else if (event.subtype == UIEventSubtypeRemoteControlNextTrack){
NSLog(@"Responds nice to the event UIEventSubtypeRemoteControlNextTrack");
} else if (event.subtype == UIEventSubtypeRemoteControlPreviousTrack){
NSLog(@"Responds nice to the event UIEventSubtypeRemoteControlPreviousTrack");
} else if (event.subtype == UIEventSubtypeRemoteControlStop){
NSLog(@"Responds nice to the event UIEventSubtypeRemoteControlStop");
}
}
}
如何激活在backgroud音频中运行的遥控器(见屏幕截图)中的栏(iPhone被阻止)。甚至不知道是否可能。
¿有可能吗?在'音乐原生App iOS'工作正常!

AVPlayer
类有seekToTime:
方法,可以执行您想要的操作。
在进度条回调中,将进度条位置所代表的百分比乘以媒体总时间,并将该值传递给seekToTime:
