iOS-自动布局'；无法同时满足约束'；

我正在尝试修复运行应用程序时不断出现的这些错误

我有一个使用原型单元的UITableView，尽管Xcode脚本中没有列出约束问题的错误，但我还是不断地得到这些错误。 不知道如何阅读这些错误，所以希望有人能帮助我

应拉伸整个单元格宽度/高度的背景UIImageView:

应拉伸整个单元格宽度/高度的背景UIImageView：

您希望图像视图拉伸整个单元格，但有一条规则将纵横比锁定为1:2.5。您需要删除此规则

UIImageView（5），假设宽度/高度匹配，以单元格中的第三个UIImageView为中心，彼此之间的距离相等（当旋转到横向时，这些项目保持居中，第一个/最后一个单元格的左/右距离刚好增加）：

这个问题要复杂得多，但我会冒险猜测，这是同一个纵横比问题。这次是

Bobblehead_TV。BobbleheadImageView:0x100715ff0.width==0.5*Bobblehead_TV。BobbleheadImageView:0x100715ff0.height

将纵横比锁定在1:0.5。

我的朋友

原因可能是 1:您没有足够的约束来满足布局。或 2:您添加了超过所需的约束

因此，布局不明确。它是混乱的，所以警告

我的意见是重新检查你所有的限制。并提供最小的约束，但要具体。

谢谢

您是否正在调整UITableViewCellContentView或BobbleHadimageView的大小或设置其框架？我还建议删除故事板中的所有约束，并逐个重新添加。除了根据iPhone或iPad设置“EstimatedHeightForRowatineXpath”和“HeightForRowatineXpath”中的高度外，不要以编程方式调整任何内容的大小。这些高度与原型高度不同，只是因为情节提要在默认情况下使控制器为600x600。我希望避免删除所有约束条件，并尽可能重新添加，因为有很多约束条件，而且在运行应用程序时，我花了很长时间才让它真正完美地工作。这与设置高度有关。您能否删除单元格顶部和底部的约束，并查看它是否至少消除了错误？
