无法找出NSLayoutConstraint冲突

Question

我使用autolayout设置了一个自定义UITableViewCell。但是，在运行代码时，会出现以下自动收费错误：

"<NSLayoutConstraint:0x7fd6e3565900 UIImageView:0x7fd6e3566360.width == 0.833333*UIImageView:0x7fd6e3566360.height>",
"<NSLayoutConstraint:0x7fd6e3566290 V:|-(0)-[UIImageView:0x7fd6e3566360]   (Names: '|':UIView:0x7fd6e3579050 )>",

"<NSLayoutConstraint:0x7fd6e3563ec0 H:|-(0)-[UIImageView:0x7fd6e3566360]   (Names: '|':UIView:0x7fd6e3579050 )>",
"<NSLayoutConstraint:0x7fd6e3564140 V:[UIImageView:0x7fd6e3566360]-(8)-[UILabel:0x7fd6e3565560'Hello']>",

"<NSLayoutConstraint:0x7fd6e3564320 V:[UILabel:0x7fd6e3565560'Hello']-(8)-[UIButton:0x7fd6e356b2a0]>",
"<NSLayoutConstraint:0x7fd6e35676d0 H:|-(5)-[UIView:0x7fd6e3579050]   (Names: '|':UIView:0x7fd6e1de1370 )>",

"<NSLayoutConstraint:0x7fd6e3567770 H:[UIView:0x7fd6e3579050]-(5)-|   (Names: '|':UIView:0x7fd6e1de1370 )>",
"<NSLayoutConstraint:0x7fd6e35677c0 V:[UIView:0x7fd6e3579050]-(5)-|   (Names: '|':UIView:0x7fd6e1de1370 )>",

"<NSLayoutConstraint:0x7fd6e35679d0 H:[UIView:0x7fd6e1de1370]-(0)-|   (Names: '|':UITableViewCellContentView:0x7fd6e3568fe0 )>",
"<NSLayoutConstraint:0x7fd6e3567a20 V:[UIView:0x7fd6e1de1370]-(0)-|   (Names: '|':UITableViewCellContentView:0x7fd6e3568fe0 )>",
"<NSLayoutConstraint:0x7fd6e3567a70 H:|-(0)-[UIView:0x7fd6e1de1370]   (Names: '|':UITableViewCellContentView:0x7fd6e3568fe0 )>",
"<NSLayoutConstraint:0x7fd6e370c0b0 'UIView-Encapsulated-Layout-Height' V:[UITableViewCellContentView:0x7fd6e3568fe0(363.5)]>",
"<NSLayoutConstraint:0x7fd6e370c060 'UIView-Encapsulated-Layout-Width' H:[UITableViewCellContentView:0x7fd6e3568fe0(375)]>"
)

Will attempt to recover by breaking constraint 
<NSLayoutConstraint:0x7fd6e3565900 UIImageView:0x7fd6e3566360.width == 0.833333*UIImageView:0x7fd6e3566360.height>

正如您所看到的，它试图打破我为UIImageView设置的5:6比率(尽管它在屏幕上所做的事情没有明显的区别)。我需要确保这个5:6的比例保持不变，然而，我有点困惑于它与什么冲突。任何帮助都将不胜感激。

结果，我不得不将直接连接到UIImageView的垂直约束设置为稍微低于UIImageView方面约束的优先级。
