应用打断事件处理

app播放声音被打断处理

- (void)audioPlayerBeginInterruption:(AVAudioPlayer *)player此方法在iOS8已经废弃

/* AVAudioPlayer INTERRUPTION NOTIFICATIONS ARE DEPRECATED - Use AVAudioSession instead. */ 

改用 AVAudioSession 通知AVAudioSessionInterruptionNotification 

文档信息 

/* Registered listeners will be notified when the system has interrupted the audio session and when

the interruption has ended.  Check the notification's userInfo dictionary for the interruption type -- either begin or end.

In the case of an end interruption notification, check the userInfo dictionary for AVAudioSessionInterruptionOptions that

indicate whether audio playback should resume.

*/

播放声音的时候注册通知

// 注册打断通知[[NSNotificationCenterdefaultCenter] addObserver:selfselector:@selector(AVAudioSessionInterruptionNotification:) name:AVAudioSessionInterruptionNotificationobject:session];

实现方法

// 接收通知方法

- (void)AVAudioSessionInterruptionNotification: (NSNotification*)notificaiton {

NSLog(@"%@", notificaiton.userInfo); 

 }

打电话 测试 打印出 AVAudioSessionInterruptionTypeKey = 1 

/* keys for AVAudioSessionInterruptionNotification *//* value is an NSNumber representing an AVAudioSessionInterruptionType */typedefNS_ENUM(NSUInteger,AVAudioSessionInterruptionType){AVAudioSessionInterruptionTypeBegan=1,/* the system has interrupted your audio session */AVAudioSessionInterruptionTypeEnded=0,/* the interruption has ended */}NS_AVAILABLE_IOS(6_0);

可以通过通知信息中的type 来做不同的操作

// 接收通知方法

- (void)AVAudioSessionInterruptionNotification: (NSNotification*)notificaiton {

NSLog(@"%@", notificaiton.userInfo);

AVAudioSessionInterruptionTypetype = [notificaiton.userInfo[AVAudioSessionInterruptionTypeKey] intValue];

if(type ==AVAudioSessionInterruptionTypeBegan) { 

 [self.player pause]; }else{ [self.player play];

 }

}
