使用如下：注：我是配合snpkit布局使用的，所以不写frame属性
实例一个UIButton,
1 private let sureButton = UIButton() 2 .fontSize(UIFont.systemFontSize()) 3 .title("确定", forState: .Normal) 4 .titleColor(.whiteColor(), forState: .Normal) 5 .titleColor(.smallGreenColor(), forState: .Highlighted) 6 .backgroundColor(.smallGrayColor(), forState: .Normal) 7 .backgroundColor(.whiteColor(), forState: .Highlighted) 8 .borderColor(.smallGrayColor()) 9 .borderWidth(1) 10 .cornerRadius(8) 11 .userInteractionEnabled(false)
实例一个UILable,
private let tipTextLabel = UILabel() .fontSize(14) .text("请填写您本人的银行卡信息") .textColor(.grayColor())
附各个UI控件源码:
