Ios 无法同时满足自定义标题节的约束

对于表视图，我的自定义标题部分有一个.nib：

自定义标题部分可以工作，但每当我插入新部分时，控制台上就会显示一条警告：

2017-10-02 14:56:32.791529+0800 Project[1017:14993] [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.

Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKit/UIView.h> may also be helpful.

可能下面列表中至少有一个约束是您不想要的。
试试这个：
（1） 看看每一个约束，试着找出你不期望的；
（2） 找到添加了不需要的约束的代码，然后修复它。

将尝试通过打破约束进行恢复
在UIViewAlertForUnsatifiableConstraints处创建一个符号断点，以便在调试器中捕获该断点。
中列出的UIView上UIConstraintBasedLayoutDebugging类别中的方法也可能会有所帮助。

我试图找到不需要的约束并删除它们，但我定义的布局在其他设备上不再适用。忽略此警告是否安全？我不知道如何调试这个。。。请帮忙

您应该将

BtnAdd.training

优先级降低到1000以下。看起来autolayout添加了一个临时约束

”

这会压扁所有内容，因此删除绝对优先级将使您的内容调整时不会发生冲突

另外，为什么

TxtName.width

=

LblPrice.width

？您不能调整内容包含优先级吗？

尝试将“添加项目宽度约束”按钮的

优先级设置为999，然后查看是否仍显示警告。@Amit我刚刚将其设置为999。不幸的是，警告仍然显示…请尝试将“添加项目宽度约束”按钮的
优先级设置为999，然后查看是否仍然显示警告。@Amit我刚刚将其设置为999。不幸的是，警告仍然显示…谢谢！它起作用了。。。我想做一个文本字段，当你编辑时，自动调整宽度，但是中间也留一些空间，以便在点击时结束编辑，但是我不确定如何正确地设置它。这实际上是聪明的。我想你想让标签填充剩余的宽度。此外，人们通常不知道如何使用拥抱优先级和抗压性，但您的解决方案听起来不错。谢谢！它起作用了。。。我想做一个文本字段，当你编辑时，自动调整宽度，但是中间也留一些空间，以便在点击时结束编辑，但是我不确定如何正确地设置它。这实际上是聪明的。我想你想让标签填充剩余的宽度。此外，人们通常不知道如何使用拥抱优先权和压缩阻力，但您的解决方案听起来不错。
