ios - UIImagePickerController - 横向拍摄的照片在顶部创建黑条

Question

我正在使用 UIImagePickerViewController (UIImagePickerControllerSourceTypeCamera) 在我的应用中拍照。但是，当以风景拍摄照片时，预览/裁剪 View 中的图像顶部会出现一个大黑条(底部也有一个细长的黑条)。像这样 -

这是我的代码-

UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.allowsEditing = YES;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;

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

相比之下，当从照片库中挑选风景照片时，它位于预览的中心，顶部和底部甚至有黑色条。

这是从哪里来的？我该如何摆脱它？

#pragma mark UIImagePickerControllerDelegate

- (void)imagePickerController:(UIImagePickerController *)picker  didFinishPickingMediaWithInfo:(NSDictionary *)info {

UIImage *img = nil;

CGRect cropRect = [[info valueForKey:UIImagePickerControllerCropRect] CGRectValue];

if (cropRect.origin.y < 0) {

    img = [info objectForKey:UIImagePickerControllerOriginalImage];

} else {

    img = [info objectForKey:UIImagePickerControllerEditedImage];

}

}
