我在 XCode 界面构建器中建立一个 UI 。 在设定了所需的视图等级后, 我意识到, 靠近该等级顶端的视图之一应该是 UIScrollView , 而不是 UIView 。
是否有办法可以轻易地改变这种观点, 从UIView到UIScrollView, 而不必用他们自己的子视图等级重置所有儿童组成部分?
是的, 请单击您想要更改的 < code> UIView 。 在选中它后, 打开身份检查器窗格 。
从身份检查员那里,你应该看到最上面命名为“类”的字段,以灰色字表示的当前值应该是“UIView”。
输入 UIScroll View 并点击 Enter 。
这将更新您的 Nib 文件以及我之前的 UIOView 到 UIScrollView 。 此外, 如果您已经将视图连接到 IB Outlet , 请确定您更新了 IBoutlet 类定义, 如果它不是 id 。
据我所知,最简单的方式是右键单击相应的.xib 文件,然后选择 Opern As -- & gt; source Code 。然后您可以找到您想要更改的视图。它看起来是这样的 。
<view contentMode="scaleToFill" translatesAutoresizingMaskIntoConstraints="NO" id="0gr-sH-vvn">
.
.
.
</view>
换成
<scrollView clipsSubviews="YES" multipleTouchEnabled="YES" contentMode="scaleToFill" translatesAutoresizingMaskIntoConstraints="NO" id="0gr-sH-vvn">
.
.
.
</scrollView>
基本上,您需要将 view 更改为 scrollView ,当您在界面构建者情绪 < em> 下通过属性检查员部分修改这些属性时,其他属性将自动生成(右键单击.xib 文件,并选择 Opern As -- & gt;界面构建器 XIB Document )
