[IOS]播放音乐的过程中，处理来电接入，挂断来电的事件

1， 在    MyAppDelegate 的

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions 中调用

AudioSessionInitialize(NULL, NULL, interruptionListener, (__bridge void*)self);

2， 定义函数  

void interruptionListener( void *inClientData,

                          UInt32 inInterruptionState)

void interruptionListener( void *inClientData,   UInt32 inInterruptionState)

{

MyAppDelegate *pTHIS = (__bridgeMyAppDelegate*)inClientData;

if (inInterruptionState ==kAudioSessionBeginInterruption)

{

        [pTHIS.self.viewController.playerPauseQueue];

        NSLog(@"被打断，暂停播放");

    }

elseif (inInterruptionState == kAudioSessionEndInterruption)

{

// we were playing back when we were interrupted, so reset and resume now        

        [pTHIS.self.viewController.playerStartQueue:TRUE];

        

        NSLog(@"被打断结束，重新开始播放");

}

}
