iOS：在故事板中将子类从UIView更改为UIScrollView [英] iOS: Changing subclass from UIView to UIScrollView in a storyboard

问题描述

我创建了一个基于故事板的项目。在其中一个视图控制器的视图中，需要放置一些额外的元素，这会导致视图高度增加，从而视图现在必须是可滚动的。是否可以在故​​事板中简单地将UIView的类类型更改为UIScrollView？它真的会将顶级UIView转换为UIScrollView吗？只是在没有太多变化的情况下寻找快速简便的方法。

I have created a storyboard based project. In one of the view controller's view requires some extra elements to be placed which results in increasing the view height such that the view must now be scrollable. Is it possible to simply change the class type of UIView to UIScrollView in storyboard? Will it really convert the top level UIView to UIScrollView ? Just looking for a quick and easy way of doing this without much changes.

谢谢

推荐答案

您必须将 UIView 类型更改为 UIScrollView （身份检查员）并在控制器中 viewDidLoad 方法通过将视图转换为 UIScrollView contentSize c>：

You have to change the UIView type to UIScrollView (identity inspector) and in the controller viewDidLoad method assign the view a contentSize by casting the view to a UIScrollView :

[(UIScrollView *)self.view setContentSize:CGSizeMake(320, 700)];
