我正在使用以下代碼來檢測可用輸出,並且它沒有拿起連接的藍牙設備。我知道我的藍牙設備已正確連接,因爲我正在播放音樂。AVAudioSession未檢測到連接的藍牙設備
let session = AVAudioSession.sharedInstance()
for description in session.currentRoute.outputs {
if description.portType == AVAudioSessionPortHeadphones {
NSLog("headphone plugged in")
let alertActin = UIAlertAction(title: "Headphones", style: UIAlertActionStyle.default, handler:nil)
alertActin.setValue(UIColor.blue, forKey: "titleTextColor")
alert.addAction(alertActin)
} else if description.portType == AVAudioSessionPortBluetoothA2DP {
NSLog("Bluetooth plugged in")
let alertActin = UIAlertAction(title: description.portName, style: UIAlertActionStyle.default, handler:nil)
alertActin.setValue(UIColor.blue, forKey: "titleTextColor")
alert.addAction(alertActin)
} else if description.portType == AVAudioSessionPortBluetoothLE {
NSLog("Bluetooth plugged in")
let alertActin = UIAlertAction(title: description.portName, style: UIAlertActionStyle.default, handler:nil)
alertActin.setValue(UIColor.blue, forKey: "titleTextColor")
alert.addAction(alertActin)
}
else {
NSLog("")
}
}
我將此添加到我的代碼,但我的藍牙音箱仍然沒有出現DO { \t \t \t嘗試session.setCategory(AVAudioSessionCategoryPlayAndRecord,具有:.allowBluetooth]) \t \t \t嘗試session.setActive(真) \t \t} {趕上 \t \t \t fatalError( 「錯誤設置音頻會話」) \t \t} – user1079052
