我有一个UIViewcontroller
带有照片框的子视图,我需要在这个框内插入相机,我在网上搜索过,我发现AVCaptureVideoPreviewLayer
AVCaptureVideoPreviewLayer *newCaptureVideoPreviewLayer = [[AVCaptureVideoPreviewLayer alloc] initWithSession:session];
[self.view.layer addSublayer:newCaptureVideoPreviewLayer];
和UIImagePickerController
self.picker = [[UIImagePickerController alloc] init];
[self.view addSubview:self.picker.view];
可以帮忙,但我无法将相机放在盒子里,我怎么能做到这一点?
