iOS 可自定義AlertView

YYAlertController

語言：Swift 5.0
原理介紹：利用UIViewController的轉場動畫，通過自定義轉場達到和系統彈出警告框一樣的效果
視圖分爲三類：

1. 標題和小標題
2. 按鈕
3. 添加TextField

視圖佈局：給View寫一個擴展，功能是封裝系統的佈局類
視圖佈局自適應
初始化：各種初始化方法，基本滿足各個場景需要
自定義視圖：支持自定義視圖，且自定義視圖的佈局可以用自動佈局的方式，不會影響最終的顯示效果。自定義佈局中也可以.alert 和 actionSheet兩種類型
場景

1. 所有類型都支持在UIWindow上顯示
2. UIViewController應用
3. 自定義視圖可以自己出發消失時間，降低耦合度hidden

樣例代碼

1.Default alert

        let alertView = YYAlertView.init(title: "提示", message: "確定要刪除嗎？")
        //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")
        }))
        //循環引用
        alertView.addAction(YYAlertAction.init("確定", style: .defalut, handler: { (action) in
            print("確定")
        }))
        alertView.show(in: self, preferredStyle: .alert)
        //alertView.show(in: self)
        
        //        let alertVC = YYAlertController.init(alertView, preferredStyle: .alert)
//        YYAlertController.initWithAlertView(alertView) //另一種初始方法
//        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("確定", style: .defalut, handler: { (action) in
                print("確定")
        }))
        alertView.show(in: self, preferredStyle: .actionSheet)

3. ShowInWindow

//文本自適應
        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("確定", style: .defalut, handler: { (action) in
            
        }))
        alertView.showInWindow()

4. TextField Alert

      let alertView = YYAlertView.init(title: "提示", message: "輸入相關信息")
        alertView.layer.cornerRadius = 8
        alertView.layer.masksToBounds = true
        //        alertView.buttonDefaultBgColor = UIColor.red
        alertView.addTextFieldWithConfigurationHandler { (textField) in
            print(textField.text)
            textField.placeholder = "請輸入手機號"
        }
        alertView.addTextFieldWithConfigurationHandler { (textField) in
            print(textField.text)
            textField.placeholder = "請輸入密碼"
        }
        alertView.addAction(YYAlertAction.init("取消", style: .cancle, handler: { (action) in
                print("取消啦")
        }))
        alertView.addAction(YYAlertAction.init("確定", style: .defalut, handler: { (action) in
                print("確定")
        }))
        alertView.show(in: self, preferredStyle: .alert)

5. CustomView

//支持自定義視圖，包括利用xib創建的視圖
        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)

效果圖如下
