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/或我无法让它们发挥作用。我尝试了所有info.plist更改等。

我正在使用UIImagePickerController。拍摄照片后，预览图像（使用“重新拍摄”和“使用照片选项”）会向下跳跃约20个像素。它似乎占据了mediaTypes工具栏区域。

有关如何防止图像移位的任何建议？这是相关的代码（非常基本的）

- (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

在尝试了许多无法正常工作的配置后，我采用了一种简单的方法，将相机视图强制缩小了预览图像使用变换移动的相同像素数，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];
}

UIImagePickerController预览图像向下移动
