iOS:AVCaptureDevicePosition，如何从 SCRecorder 获取(错误:Bad receiver type)

Question

我有一些代码，在 objective-c 中，如下所示:

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

}

而且我想获取事件设备/相机(无论是前面的还是后面的)，如下所示:

AVCaptureDevicePosition position = [[_recorder device] position];

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

我做错了什么？

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;
