将图片插入Word文档时如何检索图像文件名(How to retrieve image filename when inserting pictures to Word document)

 我终于弄清楚问题对我来说是什么。 我正在使用viewController的 - （void）willLayoutSubviews方法来确保我有正确的边界，但我忘了看我的SKScene是否已经呈现。 这导致每次将视图放在旧视图之上时，会出现一个新的welcomeScene。 
 
-(void)willLayoutSubviews
{
    if(!self.didPresentScene)
    {
        // Present scene here
        ....
        self.didPresentScene = YES;
    }
}

I finally figured out what the problem was for me. I was using the -(void)willLayoutSubviews method of the viewController to ensure I had the correct bounds, but I had forgotten to see if my SKScene was already presented. That resulted in a new welcomeScene being presented each time the view was laid out on top of the old one.
 
-(void)willLayoutSubviews
{
    if(!self.didPresentScene)
    {
        // Present scene here
        ....
        self.didPresentScene = YES;
    }
}
