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]];


}

我已经实现了代表

UINavigationControllerDelegate,UIImagePickerControllerDelegate

拍摄图像后，我可以看到“移动和缩放”框，但是当我移动它时，该框会返回到初始位置-就像它反弹回来一样。

这是为什么？

最佳答案

看起来这是由于您正在请求UIImagePickerControllerOriginalImage引起的，根据文档，此文件将返回“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，在重新阅读了几次问题之后，如果问题本身出现在选择器中，则可能无济于事。
