iOS 可自定义AlertView

YYAlertController

语言：Swift 5.0
原理介绍：利用UIViewController的转场动画，通过自定义转场达到和系统弹出警告框一样的效果
视图分为三类：

1. 标题和小标题
2. 按钮
3. 添加TextField

视图布局：给View写一个扩展，功能是封装系统的布局类
视图布局自适应
初始化：各种初始化方法，基本满足各个场景需要
自定义视图：支持自定义视图，且自定义视图的布局可以用自动布局的方式，不会影响最终的显示效果。自定义布局中也可以.alert 和 actionSheet两种类型
场景

1. 所有类型都支持在UIWindow上显示
2. UIViewController应用
3. 自定义视图可以自己出发消失时间，降低耦合度hidden

样例代码

1.Default alert

        let alertView = YYAlertView.init(title: "提示", message: "确定要删除吗？")
        //alertView.layer.cornerRadius = 8
        //alertView.layer.masksToBounds = true
//        alertView.buttonDefaultBgColor = UIColor.red
        alertView.addAction(YYAlertAction.init("取消", style: .cancle, handler: { (action) in
            print("取消啦")
        }))
        //循环引用
        alertView.addAction(YYAlertAction.init("确定", style: .defalut, handler: { (action) in
            print("确定")
        }))
        alertView.show(in: self, preferredStyle: .alert)
        //alertView.show(in: self)
        
        //        let alertVC = YYAlertController.init(alertView, preferredStyle: .alert)
//        YYAlertController.initWithAlertView(alertView) //另一种初始方法
//        self.present(alertVC, animated: true, completion: nil)

2.ActionSheet

        let alertView = YYAlertView.init(title: "提示", message: "info")
        alertView.layer.cornerRadius = 8
        alertView.layer.masksToBounds = true
    //        alertView.buttonDefaultBgColor = UIColor.red
        alertView.addAction(YYAlertAction.init("取消", style: .cancle, handler: { (action) in
                print("取消啦")
        }))
        alertView.addAction(YYAlertAction.init("summit", style: .defalut, handler: { (action) in
                print("取消啦")
        }))
        alertView.addAction(YYAlertAction.init("确定", style: .defalut, handler: { (action) in
                print("确定")
        }))
        alertView.show(in: self, preferredStyle: .actionSheet)

3. ShowInWindow

//文本自适应
        let alertView = YYAlertView.alertViewWithTitle("YYAlertView", message: "A message should be a short, but it can support long message, this is ver heard HHhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh. (NSTextAlignmentCenter)")
        alertView.addAction(YYAlertAction.init("取消", style: .cancle, handler: { (action) in
            
        }))
        alertView.addAction(YYAlertAction.init("确定", style: .defalut, handler: { (action) in
            
        }))
        alertView.showInWindow()

4. TextField Alert

      let alertView = YYAlertView.init(title: "提示", message: "输入相关信息")
        alertView.layer.cornerRadius = 8
        alertView.layer.masksToBounds = true
        //        alertView.buttonDefaultBgColor = UIColor.red
        alertView.addTextFieldWithConfigurationHandler { (textField) in
            print(textField.text)
            textField.placeholder = "请输入手机号"
        }
        alertView.addTextFieldWithConfigurationHandler { (textField) in
            print(textField.text)
            textField.placeholder = "请输入密码"
        }
        alertView.addAction(YYAlertAction.init("取消", style: .cancle, handler: { (action) in
                print("取消啦")
        }))
        alertView.addAction(YYAlertAction.init("确定", style: .defalut, handler: { (action) in
                print("确定")
        }))
        alertView.show(in: self, preferredStyle: .alert)

5. CustomView

//支持自定义视图，包括利用xib创建的视图
        let customView = YCustomView.init(frame: CGRect.init(x: 0, y: 0, width: UIScreen.main.bounds.width * 0.7, height: 300))
        titleView.backgroundColor = UIColor.white
        let alertVC = YYAlertController.init(titleView, preferredStyle: .alert)
        alertVC.bcgTapDismissEnable = true
        self.present(alertVC, animated: true, completion: nil)
