【问题描述】:
我正在使用 AVPlayer 在我的应用中播放视频,现在我想让视频在后台模式下播放。
这是我在- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 中输入的内容:
[[AVAudioSession sharedInstance] setDelegate: self];
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback error:nil];
我还添加到 plist: 所需的背景模式 -> 应用播放音频
我也添加了这个:
-(void)viewDidAppear:(BOOL)animated{
[super viewDidAppear:animated];
[[UIApplication sharedApplication] beginReceivingRemoteControlEvents];
[self becomeFirstResponder];
}
- (BOOL)canBecomeFirstResponder {
return YES;
}
- (void)remoteControlReceivedWithEvent:(UIEvent *)event {
switch (event.subtype) {
case UIEventSubtypeRemoteControlTogglePlayPause:
NSLog(@"4");
break;
case UIEventSubtypeRemoteControlPlay:
break;
case UIEventSubtypeRemoteControlPause:
NSLog(@"3");
break;
case UIEventSubtypeRemoteControlNextTrack:
NSLog(@"2");
break;
case UIEventSubtypeRemoteControlPreviousTrack:
NSLog(@"1");
break;
default:
break;
}
}
当我将应用程序移到后台并按下按钮时,nslog 会打印到控制台
我需要添加其他内容吗?
