我有一个录音应用程序。我遇到了一个问题，当我打开我的应用程序并且手机与蓝牙设备配对时，一旦我开始录制，蓝牙设备就会认为我正在打电话。它发出呼出声，并在屏幕上显示＆＃34; ON CALL＆＃34; （总是谈论BT设备），但当然没有实际的电话。
这就是我目前正在初始化会话的方式：
[[AVAudioSession sharedInstance] overrideOutputAudioPort:AVAudioSessionPortOverrideNone
error:nil];
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayAndRecord
withOptions:AVAudioSessionCategoryOptionMixWithOthers |
AVAudioSessionCategoryOptionAllowBluetooth
error: nil];
我在2个不同的蓝牙设备上尝试过，同样的结果也是如此。两人都试图建立电话。
在查看BlueTooth日志之后，我发现了一些关于它正在做什么的线索：

什么是设置虚拟通话???我在代码中唯一能做的就是
[self.audioRecorder record];
self.audioRecorder当然是AVAudioRecorder的一个实例。
我该如何防止这种情况？
答案 0 :(得分：0)
每当您想要开始录制并且不允许蓝牙时，请更改AVAudioRecorder选项：
- (void)audioRecorderDidFinishRecording:(AVAudioRecorder *)recorder successfully:(BOOL)flag完成录制后，在AVAudioSession实例的委托调用中：
AVAudioSessionCategoryOptionAllowBluetooth
设置回AVAudioSession选项以允许蓝牙{{1}}这样{{1}}不会认为录制输入应作为来自所连接BT设备的语音呼叫处理。
