利用链式编程方法简化基础控件的写法，需要的属性可以向后拼接
- 导入 pods
pod 'ChainControl'
- 手动导入，直接拖拽
ChainControl文件夹到您的项目中
- 原生示例
let btn = UIButton(frame: CGRect(x: 10, y: 200, width: 50, height: 50))
btn.setTitle("button", for: .normal)
btn.setTitleColor(.white, for: .normal)
btn.titleLabel?.font = .systemFont(ofSize: 16)
btn.backgroundColor = .blue
btn.layer.shadowColor = UIColor.gray.cgColor
btn.layer.shadowOpacity = 1
btn.layer.shadowOffset = CGSize(width: 1, height: 1)
btn.layer.shadowRadius = 2
self.view.addSubview(btn)
- ChainControl 示例
let btnExample = UIButton(frame: CGRect(x: 10, y: 100, width: 50, height: 50)).ctrl_title("button").ctrl_titleColor(.white).ctrl_font(.systemFont(ofSize: 16)).ctrl_backgroundColor(.blue).ctrl_shadow(color: .gray)
self.view.addSubview(btnExample)
