如何获取iOS设备摄像头名称？

Question

IOS捕获设备和回放设备是否有名称或路径？通常我们可以在windows中获取连接摄像头的路径和名称，我想在Mac中也可以这样做。有谁知道如何在IOS上获取采集和播放设备的名称和路径？

  // 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;
        }
    }
}

Answer 2

你得到了设备名下面的方法

NSString *name =[[UIDevice currentDevice] name]);

Answer 3

遗憾的是，“设备”在iOS 10.0中已被弃用。请改用AVCaptureDeviceDiscoverySession。
