  • 自动布局报错(两条连线冲突):Unable to simultaneously satisfy constraints

     这个报错有些长:

    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:0x600000096580 H:[UIButton:0x7fc8eb408a50'Button']-(2)-|   (active, names: '|':UIView:0x7fc8eb40d330 )>",
        "<NSLayoutConstraint:0x600000096670 H:[UIButton:0x7fc8eb408a50'Button']-(3)-|   (active, names: '|':UIView:0x7fc8eb40d330 )>"
    )

    Will attempt to recover by breaking constraint
    <NSLayoutConstraint:0x600000096670 H:[UIButton:0x7fc8eb408a50'Button']-(3)-|   (active, names: '|':UIView:0x7fc8eb40d330 )>

    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.

    我的报错原因: 就是同意的边距连了两条线(2 conflicting constrains);

                       

                       点击 黄色的警告(⚠️),找到冲突的线,检查,很容易找到问题。

            之前好像是直接显示红色报错的,now是 黄色警告?
