我在将项目添加到滚动视图时遇到了一些麻烦。现在，我已经将所有项目以编程方式添加到滚动视图中，但遇到了有关自动布局的一些问题。我不完全了解如何在不执行所有编程的情况下将项目添加到滚动视图中，或者至少通过添加某种形式的自动布局，以便在不同设备上看起来不那么糟糕。请让我知道你是否可以帮忙。我的代码如下。Swift - 如何在ScrollView中使用项目的自动布局？
谢谢！
P.S. Textfields被添加到一个单独的函数中。
P.S.S.有些图片是文字，但它们被用作图片，因为您无法在iOS中对它们进行格式化，以获得我期望的所需外观。

好吧，但不会混乱跨页面的间距？另外，如何在Main.storyboard中为每个页面执行此操作？ – surfmaster96
跨页面的含义是什么？你是否在不同的viewControllers中使用相同的scrollView？ – Malik
