我正在尝试使用实时取景的前置摄像头.我可以使用下列相机：
var backCamera = AVCaptureDevice.defaultDeviceWithMediaType(AVMediaTypeVideo)
但我似乎找不到如何获得前置摄像头.如何更改上述代码以使用前置摄像头？
解决方法
这是我的一个项目的工作示例,以获得前置摄像头.这是客观的,但被证明是工作和容易转换成迅速.
NSArray *videoDevices = [AVCaptureDevice devicesWithMediaType:AVMediaTypeVideo];
AVCaptureDevice *captureDevice = nil;
for (AVCaptureDevice *device in videoDevices){
if (device.position == AVCaptureDevicePositionFront){
captureDevice = device;
break;
}
}
在Swift(未测试)中：
let videoDevices = AVCaptureDevice.devicesWithMediaType(AVMediaTypeVideo)
var captureDevice:AVCaptureDevice
for device in videoDevices{
let device = device as AVCaptureDevice
if device.position == AVCaptureDevicePosition.Front {
captureDevice = device
break
}
}
