iOS: AVCaptureDevicePosition, how to get from SCRecorder (error: Bad receiver type)

Question

我有一些代码，在objective-c，如下：

@interface SCRecorderPViewController () {
    SCRecorder *_recorder;
    UIImage *_photo;
    SCRecordSession *_recordSession;
    UIImageView *_ghostImageView;
    CGFloat screenWidth;
    CGFloat screenHeight;

}

而我想获取activedevice/camera（不管是前面的，还是后面的），这样：

AVCaptureDevicePosition position = [[_recorder device] position];

但是我得到一个错误：Bad receiver type 'AVCaptureDevicePosition' (aka 'enum AVCaptureDevicePosition')

我在做什么"wrong"？

谢谢！

Answer 1

这应该有效：

AVCaptureDevicePosition position = [_recorder device];

请注意在源文件中。

/**
 Change the current used device
 */

@property (assign, nonatomic) AVCaptureDevicePosition device;
