大佬教程收集整理的这篇文章主要介绍了ios – Autolayout约束警告“将尝试通过打破约束来恢复”，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。

概述

我正在尝试实施新闻提要(不知何故像没有评论或喜欢的Instagram).它工作,但 xcode继续显示此错误.我尝试改变所有约束,然而,我无法开始工作. tableview的高度为475,图像的高度为400,带有标签的白色区域为75. 我确实用过 self.tableView.estimatedRowHeight = 475; self.tableView.rowHeight = UITableV

我确实用过

self.tableView.estimatedRowHeight = 475;
self.tableView.rowHeight = UITableViewAutomaticDimension;

有帮助吗？

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. (Note: If you're seeing NSAutoresizingMaskLayoutConsTraints that you don't understand,refer to the documentation for the UIView property translatesAutoresizingMaskIntoConsTraints)

Will attempt to recover by breaking consTraint 
<NSLayoutConsTraint:0x174097b60 V:[UIImageView:0x1743e9000(30)]>

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.
