ios - imagePickerController 移动和缩放不起作用

Question

这是我的代码:

-(void) takePhoto
{
    UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];
    imagePickerController.sourceType = UIImagePickerControllerSourceTypeCamera;
    //imagePickerController.editing = YES;
    imagePickerController.allowsEditing=YES;
    imagePickerController.delegate = self;

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

#pragma mark - Image picker delegate methods
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
    [picker dismissViewControllerAnimated:NO completion:nil];

    [self.Picture setImage:[info objectForKey:UIImagePickerControllerOriginalImage]];


}

我已经实现了委托(delegate)

UINavigationControllerDelegate,UIImagePickerControllerDelegate

图像已拍摄，我可以看到移动和缩放框，但当我移动它时，框会返回到初始位置 - 就像它反弹回来一样。

这是为什么？

看起来这是因为您正在请求 UIImagePickerControllerOriginalImage，根据文档，这会返回“用户选择的原始、未裁剪图像”。

尝试将其更改为 UIImagePickerControllerEditedImage。

编辑:实际上，在重新阅读问题几次之后，如果问题出现在选择器本身中，这可能无济于事。
