Swift_UIButton

1.初始化

        /**
         UIButtonType.system:前面不带图标,默认文字颜色为蓝色,有触摸时的高亮效果
         UIButtonType.custom:定制按钮,前面不带图标,默认文字颜色为白色,无触摸时的高亮效果
         UIButtonType.contactAdd:前面带“+”图标按钮,默认文字颜色为蓝色,有触摸时的高亮效果
         UIButtonType.detailDisclosure:前面带“!”图标按钮,默认文字颜色为蓝色,有触摸时的高亮效果
         UIButtonType.infoDark:为感叹号“!”圆形按钮
         UIButtonType.infoLight:为感叹号“!”圆形按钮
         (注意:自ios7起,infoDark、infoLight、detailDisclosure效果都是一样的)
         */
        let buttonOne = UIButton.init(type: UIButtonType.custom)

2. 设置

        /**
         normal
         highlighted
         disabled
         selected
         */
        buttonOne.setTitle("这个是一个button", for: UIControlState.normal)
        buttonOne.setImage(UIImage.init(named: "1.jpg"), for: UIControlState.normal)
        
        // 设置背景颜色
        buttonOne.setBackgroundImage(UIImage.init(named: "2"), for: UIControlState.normal)
        
        // 点击事件
        buttonOne.addTarget(self, action: #selector(buttonOneClicked), for: UIControlEvents.touchUpInside)

3.代码

import UIKit

let kScreenWidth = UIScreen.main.bounds.size.width


class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        
        self.addButtonOne()
    }
    
    
    func addButtonOne() {
        
        self.view.addSubview(buttonOne)
    }
    
    func buttonOneClicked()  {
        print("点击了")
    }
    
    // 懒加载一个UIButton
    lazy var buttonOne: UIButton = {

        /**
         UIButtonType.system:前面不带图标,默认文字颜色为蓝色,有触摸时的高亮效果
         UIButtonType.custom:定制按钮,前面不带图标,默认文字颜色为白色,无触摸时的高亮效果
         UIButtonType.contactAdd:前面带“+”图标按钮,默认文字颜色为蓝色,有触摸时的高亮效果
         UIButtonType.detailDisclosure:前面带“!”图标按钮,默认文字颜色为蓝色,有触摸时的高亮效果
         UIButtonType.infoDark:为感叹号“!”圆形按钮
         UIButtonType.infoLight:为感叹号“!”圆形按钮
         (注意:自ios7起,infoDark、infoLight、detailDisclosure效果都是一样的)
         */
        let buttonOne = UIButton.init(type: UIButtonType.custom)
        
        
        buttonOne.frame = CGRect.init(x: 10, y: 100, width: kScreenWidth - 20, height: 40)
        buttonOne.backgroundColor = UIColor.red
        
        
        /**
         normal
         highlighted
         disabled
         selected
         */
        buttonOne.setTitle("这个是一个button", for: UIControlState.normal)
        buttonOne.setImage(UIImage.init(named: "1.jpg"), for: UIControlState.normal)
        
        // 设置背景颜色
        buttonOne.setBackgroundImage(UIImage.init(named: "2"), for: UIControlState.normal)
        
        // 点击事件
        buttonOne.addTarget(self, action: #selector(buttonOneClicked), for: UIControlEvents.touchUpInside)
        
        return buttonOne
    }()
}
