我使用snapKit通过AutoLayout创建了一个表格视图动态单元格高度。构建应用程序（Result image）时，一切看起来都很好，但是我收到一些奇怪的调试消息，而且我不知道代码中的问题是什么。

我尝试了setContentCompressionResistancePriority（.defaultHigh，for：.vertical），make.bottom.equalTo（self.contentView）.offset（-10）.priority（999），但是同样的问题。现在我没有主意。 这就是我设置myView的方式：

我在单元格中设置了myView：

初始化：

contentView.addSubview(myview)

override func updateConstraints() {
        if !upCon {
            myview.setContentCompressionResistancePriority(.defaultHigh,for: .vertical)
            myview.snp.makeConstraints { (make) in
                make.top.equalTo(self.contentView).offset(10)
                make.left.equalTo(self.contentView).offset(10)
                make.width.height.equalTo(50)
                make.bottom.equalTo(self.contentView).offset(-10).priority(999)
            }
            upCon = true
        }
        super.updateConstraints()
    }

我这样设置行高：

myView.tableView.estimatedRowHeight = 100
myView.tableView.rowHeight = UITableView.automaticDimension

因此，我不想在调试日志中看到此信息（如果需要更多代码来重现此问题，我可以共享更多代码）：

[LayoutConstraints] 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.

Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKitCore/UIView.h> may also be helpful.
