问题描述
我有一个表格视图，它具有动态调整大小的单元格 - 因为它们包含一个文本视图。一切都显示正确，但我收到了一些顽固的约束错误。
我尝试以我能想到的各种方式修改和删除，但它们要么持续存在，要么破坏功能（即，删除错误会破坏功能）
这些是我用于底部单元格的约束。
以下错误：
[LayoutConstraints] Unable to simultaneously satisfy constraints.
Probably at least one of the constraints in the following list is one you don't want.
Try this:
(1) look at each constraint and try to figure out which you don't expect;
(2) find the code that added the unwanted constraint or constraints and fix it.
(
"<NSLayoutConstraint:0x282221590 UITableViewCellContentView:0x106079640.bottom == UITextView:0x1058cc000.bottomMargin + 8 (active)>","<NSLayoutConstraint:0x282221630 V:|-(2)-[UITextView:0x1058cc000] (active,names: '|':UITableViewCellContentView:0x106079640 )>","<NSLayoutConstraint:0x282222170 'UIView-bottomMargin-guide-constraint' V:[UILayoutGuide:0x283818a80'UIViewLayoutMarginsGuide']-(8)-| (active,names: '|':UITextView:0x1058cc000 )>","<NSLayoutConstraint:0x282221e50 'UIView-Encapsulated-Layout-Height' UITableViewCellContentView:0x106079640.height == 0 (active)>"
)
Will attempt to recover by breaking constraint
<NSLayoutConstraint:0x282222170 'UIView-bottomMargin-guide-constraint' V:[UILayoutGuide:0x283818a80'UIViewLayoutMarginsGuide']-(8)-| (active,names: '|':UITextView:0x1058cc000 )>
Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKitCore/UIView.h> may also be helpful.
我也试过 wtfautolayout.com，结果也有点令人困惑。
感谢任何帮助或想法
谢谢
解决方法
我推荐使用堆栈视图，你会节省一些约束，当然设计也会更好看一点，你的错误提到它是bottom = task text view.bottommargin + 8的约束。
>同样，在设计屏幕上，您的约束可能会显示为红色，它会告诉您与您的设计相矛盾或不满意的前两个。
,我设法通过更改约束之一的优先级来修复错误
