[ios]Manually Requesting Permission to Record Audio

permission.md

AVAudioSession.sharedInstance().requestRecordPermission { granted in
    if granted {
        // User granted access. Present recording interface.
    } else {
        // Present message to user indicating that recording
        // can't be performed until they change their preference
        // under Settings -> Privacy -> Microphone
    }
}

• iOS10からは、Info.plist file でNSMicrophoneUsageDescription keyでの説明文が必要
