Swift 控件横向放置,被拉伸或者压缩的问题

一个基础问题,比如，UITextField和label横向并排放置，label可能会被拉伸或者压缩

        //错误示例
        let rightLabel = UILabel()
        self.view.addSubview(rightLabel)
        rightLabel.snp.makeConstraints { make in
            make.top.right.bottom.equalToSuperview()
        }
        
        let leftTextField = UITextField()
        self.view.addSubview(leftTextField)
        leftTextField.snp.makeConstraints { make in
            make.top.left.bottom.equalToSuperview()
            make.right.equalTo(rightLabel.snp.left)
        }

这样的代码。会让rightLabel被leftTextField拉长
可以设置优先级

//不希望被拉伸
rightLabel.setContentCompressionResistancePriority(.defaultHigh, for: .horizontal)
//不希望被压缩
rightLabel.setContentHuggingPriority(.defaultHigh, for: .horizontal)

或者

//希望被拉伸
leftTextField.setContentCompressionResistancePriority(.defaultLow, for: .horizontal)
//希望被压缩
leftTextField.setContentHuggingPriority(.defaultLow, for: .horizontal)
