在Interface Builder中更新UIView类 [英] Update UIView class in Interface Builder

问题描述

我正在XCode界面构建器中构建UI。在布置了所需的视图层次结构之后，我意识到靠近层次结构顶部的一个视图应该是 UIScrollView 而不是 UIView 。

I'm building a UI in XCode interface builder. After having layed out the required view hierarchy, I realised that one of the views closer to the top of the hierarchy should be a UIScrollView and not a UIView.

有没有办法轻松地将该视图的类型从UIView更改为UIScrollView，而无需使用自己的方式重新布局所有子组件子视图层次结构？

Is there any way to easily change that view's type from UIView to UIScrollView without having to re-layout all the child components with their own sub-view hierarchies?

推荐答案

是的，点击 UIView 那个你想改变。选择它之后，打开Identity Inspector窗格。

Yes, click on the UIView that you want to change. After selecting it, open the Identity Inspector pane.

从Identity Inspector中，您应该看到顶部的一个名为'Class'的字段和当前值，以灰色显示，应该说'UIView'。

From the Identity Inspector, you should see a field at the top named 'Class', and the current value, in grey, should say 'UIView'.

输入'UIScrollView'然后按Enter键。

Enter 'UIScrollView' and hit Enter.

这将更新你的笔尖文件和我以前的 UIView 到 UIScrollView 。此外，如果您已将视图连接到 IBOutlet ，请确保更新 IBOutlet 类定义，如果它不是 id 。

This will update your Nib file and my your former UIView to a UIScrollView. Also, if you have already wired the view to an IBOutlet, make sure you update the IBOutlet class definition, if it is not an id.
