如何将堆栈视图与4个元素和堆栈视图相结合，并在XIB中使用5个元素？

发布于 2025-02-12 18:12:02 字数 453 浏览 0 评论 0原文

我正在通过XIB创建自定义的NUMPAD键盘。

NUMPAD有4行：3行，带5个按钮，最后1行带有4个按钮。

我不明白，如何对齐黄色按钮“ =”的宽度等于Uper Row的2个黄色按钮“+”和“ X”的宽度。加上3个灰色按钮宽度与上3个灰色按钮相同？

我不想添加像每个黄色按钮宽度这样的硬编码值等于60，然后“ =”按钮宽度等于120。

这就是现在的样子：

我尝试使用Google进行Google以获取解决方案，但发现只有4个元素的情况，不是5。

这是github上的测试项目：单击

原文

I am creating a custom Numpad keyboard through xib.

The numpad has 4 rows: 3 rows with 5 buttons and 1 last row with 4 buttons.

I can't understand, how to align a width of a yellow button "=" to be equal of doubled width of upper row's 2 yellow buttons "+" and "x". Plus 3 grey buttons width to be the same as upper 3 grey buttons have?

I don't want to add hardcoded values like each yellow button width equals 60 then "=" button width equals 120.

This is how it looks now:

I tried to google for solution, but found the cases only with 4 elements in a row, not 5.

Here is the test project on Github: CLICK

您似乎有很多不必要的嵌入在额外的视图和堆栈视图中...

看看：

这是该XIB的来源（取出空格，因此适合此答案）：

You have what appears to be a lot of unneeded embedding in extra views and stack views...

Take a look at this:
