UIButton的基础设置：
func creatButton(title:String,highLightTitle:String){
let button = UIButton(type:.custom);
button.frame = CGRect(x:40,y:50,width:150,height:60);
button.backgroundColor = UIColor.green;
button.setTitle(title, for: UIControlState.normal);
button.setTitle(highLightTitle, for: .highlighted);
button.setImage(UIImage(named:"Lock"), for: .normal);
button.setTitleColor(UIColor.orange, for: .normal);
button.setTitleColor(UIColor.blue, for: .highlighted);
button.titleLabel?.font = UIFont.systemFont(ofSize: 20);
button.layer.borderColor = UIColor.yellow.cgColor;
button.layer.borderWidth = 2.0;
button.layer.masksToBounds = true;
button.layer.cornerRadius = 5.0;
button.tag = 10;
button.contentHorizontalAlignment = UIControlContentHorizontalAlignment.right;
button.addTarget(self, action: #selector(buttonclick(sender:)), for: .touchUpInside);
self.view.addSubview(button);
}
func buttonclick(sender:UIButton?){
print("tag=",sender?.tag ?? 0);
print("正常:",sender?.title(for: .normal) ?? "正常");
print("高亮:",sender?.title(for: .highlighted) ?? "高亮");
print(sender?.titleColor(for: .normal) ?? "blue");
}
在viewdidLoad方法里调用
creatButton(title: "我是normal",highLightTitle: "我是highlight");
效果图如下：

打印结果：
tag= 10
正常: 我是normal
高亮: 我是highlight
