崩溃:iOS 中的 AVAudioSession 通知线程

Crashed: AVAudioSession Notify Thread in iOS

我在 AudioToolBox 中遇到 EXC_BAD_ACCESS 崩溃。如何正确处理中断?

请查看 crashlytics 屏幕截图以了解更多信息。

当我接到 phone 电话/faceTime 时,我的音频流播放器崩溃了。它实际上是非 ARC 的旧 class。只需为流 class 添加一个 InterruptionNotification Observer,如果流 class 正在播放,我们需要在中断开始时暂停播放器实例。

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(handleInterruptionChangeToState:) name:@"ASAudioSessionInterruptionOccuredNotification" object:nil];

- (void)handleInterruptionChangeToState:(NSNotification *)notification {
AudioQueuePropertyID inInterruptionState = (AudioQueuePropertyID) [notification.object unsignedIntValue];
if (inInterruptionState == kAudioSessionBeginInterruption){
    if ([self isPlaying]) {
        [self pause];

        pausedByInterruption = YES; //a global Bool variable
    }
}
else if (inInterruptionState == kAudioSessionEndInterruption){
    AudioSessionSetActive( true );
    if ([self isPaused] && pausedByInterruption) {
        [self pause]; // this is actually resume
        pausedByInterruption = NO;
    }
}

}

希望对您有所帮助。
