我正在努力让 xcode 约束正常工作，我在下面有 6 个图像和文本，在较大的 iphone 尺寸下看起来很糟糕。在 iphone SE/8 中看起来不错，但在 iphone 11 中左右图像更贴合两侧。
以下是它们在 iphone SE 和 11 中的屏幕截图： iphone SE and 11 screen shot
以下是图像的限制条件： image constraints
这里是文本限制： text constraints
非常感谢任何反馈，我不确定我在这里做错了什么
【问题讨论】：
标签： xcode autolayout
UIStackView 使这个布局相当容易实现...
对于约束，我们将从“外部”堆栈视图开始
这是它在 Storyboard 中的外观（大图，点击查看更清晰）：
这是该故事板的源代码，您可以检查它（我添加了名为“b1”/“b2”/等的图像）：
