iOS8中的UIimagepicker相机切换控制问题

Question

我正在研究UIImagepicker。我发现很奇怪，无法在iOS8上看到摄像头开关控制，但是当我点击顶部时，摄像头会切换。我的这个iOS8错误或错误吗？

但是当我在iOS7中检查时，iOS6能够看到相机切换控件。

UIImagePickerController *picker=[[UIImagePickerController alloc] init];
         picker.delegate=self;
         picker.sourceType = UIImagePickerControllerSourceTypeCamera; 
         picker.showsCameraControls=YES;
         [self presentViewController:picker animated:YES completion:nil];

Answer 1

尝试以下方法。希望它会有用。

UIImagePickerController *imgPicker = [[UIImagePickerController alloc] init];
imgPicker.delegate = self;
imgPicker.sourceType = UIImagePickerControllerSourceTypeCamera;
[self presentViewController:imgPicker animated:YES completion:NULL];
