问题描述
我已经弄清楚了如何在 ios4 上在后台播放音频,但是我注意到一些应用程序也会用自己的应用程序图标替换 iPod 基座图标.(例如 Last.fm 和 Spotify).
I've figured out how I can get audio playing in the background on ios4, however I've noticed that some apps also replace the iPod dock icon with their own app icon. (Last.fm & Spotify for example).
他们还可以使用停靠媒体控件来暂停和恢复他们的流媒体.
They are also able to use the dock media controls to pause and resume their streams.
有人知道怎么做吗?
谢谢
推荐答案
响应远程控制事件很容易.这也让您可以使用耳机控制您的应用.
It's easy you have to respond to the Remote Control Events. This also lets you control your app with the headset.
让我们说 viewDidLoad 调用:
In lets say viewDidLoad call:
[[UIApplication sharedApplication] beginReceivingRemoteControlEvents];
[self becomeFirstResponder];
你必须同时回应两者
- (BOOL)canBecomeFirstResponder {
return YES;
}
和
- (void)remoteControlReceivedWithEvent:(UIEvent *)event {
switch (event.subtype) {
case UIEventSubtypeRemoteControlTogglePlayPause:
if (audio.rate == 0.0) {
[audio play];
} else {
[audio pause];
}
break;
case UIEventSubtypeRemoteControlPlay:
[audio play];
break;
case UIEventSubtypeRemoteControlPause:
[audio pause];
break;
default:
break;
}
}
