如何知道autolayout ios中约束错误的含义？

我在应用程序中为我的视图添加了约束。我收到下面的错误消息。我无法理解约束到底出了什么问题。所以我如何理解其确切含义

    "<NSLayoutConstraint:0x7fd0135d4c30 UIImageView:0x7fd0135d7470.width == 0.634361*UIImageView:0x7fd0135d7470.height>",

我通过向每个约束添加一个唯一的id来创建解决方案。我从属性检查器添加了id。日志打印后，我添加了确切的约束id，这是导致问题的原因

下面的链接帮助了我很多

查看此链接。很好，但我无法理解什么是约束出错的问题。您要求布局是为了一些不可能的事情。它说要忽略什么才能使之成为可能？您需要查看所有相关的约束，并使其始终成为可能…向我们显示错误消息。你发布的内容只是你所有的限制。取消比例以满足多个常量是一个问题
