我有一个故事板文件，其中添加了一个 UITableView 和一个 UIView。UIView 是我尝试制作一个自定义标题，它将是半透明的，因此 tableview 将通过它可见（我不确定这是否可能，因为我是新手，这是我的第一个 iPhone 应用程序）。
在处理了与我的 ViewController 类的所有连接后，当我运行代码时，我给了我这个错误：
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)
(
"<NSAutoresizingMaskLayoutConstraint:0x8988060 h=--& v=--& V:[UIView:0x7574100(460)]>",
"<NSLayoutConstraint:0x7574780 V:|-(0)-[UIView:0x75742b0] (Names: '|':UIView:0x7574100 )>",
"<NSLayoutConstraint:0x7574700 V:[UIView:0x75742b0]-(494)-| (Names: '|':UIView:0x7574100)>"
)
Will attempt to recover by breaking constraint
<NSLayoutConstraint:0x7574700 V:[UIView:0x75742b0]-(494)-| (Names: '|':UIView:0x7574100 )>
Break on objc_exception_throw to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKit/UIView.h> may also be helpful.
关于为什么会发生这种情况的任何想法都会有所帮助。谢谢。
