AppName [2338：563134]无法同时满足约束。 可能至少以下列表中的一个约束是您不想要的约束。 试试这个： （1）看看每个约束，并试图找出你不期望的; （2）找到添加了不需要的约束或约束的代码并修复它。
"<NSLayoutConstraint:0x16663190 V:[UIView:0x16663310(48)]>",
"<NSLayoutConstraint:0x16662f80 V:|-(0)-[UIView:0x16663310] (Names: '|':UIView:0x16663400 )>",
"<NSLayoutConstraint:0x16662ef0 V:[UIView:0x166637e0]-(0)-| (Names: '|':UIView:0x16663400 )>",
"<NSLayoutConstraint:0x16662ec0 V:[UIView:0x16663310]-(1)-[UIView:0x166637e0]>",
"<NSLayoutConstraint:0x16639fb0 'UIView-Encapsulated-Layout-Height' V:[UIView:0x16663400(10)]>"
将尝试通过违反约束来恢复
在UIViewAlertForUnsatisfiableConstraints处创建一个符号断点，以便在调试器中捕获它。 UIView中列出的UIVonstraintBasedLayoutDebugging类别中的方法也可能有所帮助。
