iOS的7蓝牙输出工作不适合AVAudioSessionCategoryPlayAndRecord [英] iOS 7 Bluetooth Output not working for AVAudioSessionCategoryPlayAndRecord

问题描述

在我的应用程序，如果iPhone连接到蓝牙耳机，播放声音与蓝牙。否则使用默认的扬声器。

In my app, if iPhone is connected to Bluetooth headset, play sound with Bluetooth. Else use default speaker.

下面是我的code

[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback withOptions:AVAudioSessionCategoryOptionAllowBluetooth error:nil];
[[AVAudioSession sharedInstance] setMode:AVAudioSessionModeVoiceChat error:nil];
[[AVAudioSession sharedInstance] overrideOutputAudioPort:AVAudioSessionPortOverrideNone error:nil];
[[AVAudioSession sharedInstance] setActive:YES error:nil];

然而，当我试图用类setCategory：AVAudioSessionCategoryPlayAndRecord。路线蓝牙设备停止工作..我不知道为什么。因为通过右键，蓝牙选项应该只用于录音或PlayAndRecord类工作...

However, when I tried to use category setCategory:AVAudioSessionCategoryPlayAndRecord. Route to bluetooth device stopped working.. I don't know why. Because by right, the bluetooth option should only work for Record or PlayAndRecord category...

/ *只有AVAudioSessionCategoryRecord有效AVAudioSessionCategoryPlayAndRecord * /

/* only valid with AVAudioSessionCategoryRecord and AVAudioSessionCategoryPlayAndRecord */

增加：？我能有蓝牙只能输出（输入仍在使用默认的麦克风从电话）

Addition: Can I have bluetooth for output ONLY (input still use default Mic from phone)?

更新

我通过调用setMode第一，其次是setCategory改变的顺序。它适用于运行的应用程序（通话中）的第一次。当我试图再次做同样的动作，currentRoute还是给了我输出=蓝牙但实际产量恢复到默认的电话前置扬声器。

I changed the order by calling setMode first, followed by setCategory. It works for the first time running the application (a call). When I tried to do the same action again, currentRoute still gave me output = Bluetooth but the actual output returns to default phone front speaker.

推荐答案

这已经有一段时间，因为我张贴这个问题，我有点忘了究竟是什么问题...如果我记得正确的是因另一LIB下不停改写输出路线。不知何故，我固定它，并使其工作，我想要的方式。

It has been a while since I post this question and I kind forgot what exactly the problem is... If I remembered correctly it's due to another lib that kept rewriting the output route. somehow I fixed it and made it work the way I want.

我贡献了code到Jawbone的 AudioSessionManager 库。希望有所帮助。
