ios - UIImagePickerController 预览图片下移

Question

我知道几年前有关于这个主题的问题，但我认为他们的解决方案已经过时和/或我无法让他们工作。我尝试了所有 info.plist 更改等。

我正在使用 UIImagePickerController。拍照后，预览图像(带有重拍和使用照片选项)向下跳动约 20 像素。它似乎占据了 mediaTypes 工具栏区域。

关于如何防止图像移动的任何建议？这是相关代码(非常基本)

- (IBAction)takePhoto:(UIButton *)sender {
    UIImagePickerController *picker = [[UIImagePickerController alloc] init];
    picker.delegate = self;
    picker.sourceType = UIImagePickerControllerSourceTypeCamera;
    [picker prefersStatusBarHidden];
    [self presentViewController:picker animated:YES completion:NULL];
}

- (BOOL)prefersStatusBarHidden {
    return YES;
}

Answer 1

在尝试了很多不起作用的配置之后，我采用了一种简单的方法，并使用变换将相机 View 强制向下移动了与预览图像移动相同的像素数，即

picker.cameraViewTransform = CGAffineTransformTranslate(picker.cameraViewTransform, 0.0, 30.0);

整个方法:

- (IBAction)takePhoto:(UIButton *)sender {

    UIImagePickerController *picker = [[UIImagePickerController alloc] init];
    picker.delegate = self;
    picker.sourceType = UIImagePickerControllerSourceTypeCamera;
    picker.cameraDevice = UIImagePickerControllerCameraDeviceFront;

    picker.cameraViewTransform = CGAffineTransformTranslate(picker.cameraViewTransform, 0.0, 30.0);

    [self presentViewController:picker animated:YES completion:NULL];
}
