ios - 如何获取iOS设备的相机名称？

Question

IOS捕获设备和播放设备是否具有任何名称或路径？通常我们可以在Windows中获取连接的摄像机的路径及其名称，我想在Mac中也可以做到这一点。有人知道如何在IOS上获取捕获和回放设备的名称和路径吗？

  // RETURNS HOW MANY AUDIO CAPTURE DEVICES ARE THERE... 
  for eg: [[AVCaptureDevice devicesWithMediaType:AVMediaTypeAudio] count];

Answer 1

NSArray *devices = [AVCaptureDevice devices];
AVCaptureDevice *frontCamera;
AVCaptureDevice *backCamera;

for (AVCaptureDevice *device in devices) {

    NSLog(@"Device name: %@", [device localizedName]);

    if ([device hasMediaType:AVMediaTypeVideo]) {

        if ([device position] == AVCaptureDevicePositionBack) {
            NSLog(@"Device position : back");
            backCamera = device;
        }
        else {
            NSLog(@"Device position : front");
            frontCamera = device;
        }
    }
}
