Answer 1

Try out this amazing piece of code. Will work for sure

AVAudioSession *audioSession = [AVAudioSession sharedInstance];
NSError *err = nil;
[audioSession setCategory:AVAudioSessionCategoryPlayAndRecord withOptions:AVAudioSessionCategoryOptionAllowBluetooth  error:NULL];
[audioSession setActive:YES error:NULL];

NSString *preferredPortType = AVAudioSessionPortBluetoothHFP;
for (AVAudioSessionPortDescription *desc in audioSession.availableInputs)
{
    if ([desc.portType isEqualToString: preferredPortType])
    {
        [audioSession setPreferredInput:desc error:nil];
    }
}
