首先，您要将图像 1 添加到 imageview 2 - 您确定吗?想这样做吗?

First of all, you're adding the image 1 to imageview 2 - are you sure you want to do this?

其次，您需要将 imagview 添加到视图层次结构中，例如将其添加到 ViewControllers 视图中，如下所示:[[self view] addSubview:imageview1](如果此代码为位于视图控制器类中).

Secondly, you need to add the imagview to the view hierarchy, for example by adding it to a ViewControllers view, like this: [[self view] addSubview:imageview1] (If this code is situated within the View Controller class).
