同时使用vibrate和AVCaptureSession [英] Using vibrate and AVCaptureSession at the same time

问题描述

我在尝试在录制视频时振动手机，但我发现 AudioServicesPlaySystemSound（kSystemSoundID_Vibrate）; 不能很好地播放 AVCaptureSession 。

I'm trying to vibrate the phone while recording video, but I'm finding that AudioServicesPlaySystemSound(kSystemSoundID_Vibrate); doesn't play nicely with AVCaptureSession. Is there any other way to vibrate the phone or am I stuck with losing the vibrate function while recording video?

推荐答案

您可能需要使用这种方法设置音频与其他混音，我发现这很有用：

You probably need to set the audio to mix with other, I found this useful:

- (void)setupAudio {
    [[AVAudioSession sharedInstance] setCategory: AVAudioSessionCategoryPlayback error: nil];
    UInt32 doSetProperty = 1;
    AudioSessionSetProperty (kAudioSessionProperty_OverrideCategoryMixWithOthers, sizeof(doSetProperty), &doSetProperty);
    [[AVAudioSession sharedInstance] setActive: YES error: nil];
}

从这里
