ios – imagePickerController移动和缩放不起作用

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]];


}

我已经执行了代表们

UINavigationControllerDelegate,UIImagePickerControllerDelegate

图像被拍摄,我可以看到移动和缩放框,但是当我移动它时,框返回到初始位置 – 喜欢它反弹.

这是为什么？

解决方法

看起来这是因为您要求UIImagePickerControllerOriginalImage,根据文档返回“由用户选择的原始的未裁剪图像”.

尝试将其更改为UIImagePickerControllerEditedImage.

编辑：实际上,在重新阅读问题几次后,如果问题出现在选择器本身,这可能不会有帮助.
