Swift开发：UIAlertController 弹框

来源：互联网发布：虚拟数据库编辑：程序博客网时间：2024/04/30 11:34

封装了一个函数，用于弹框

/**

弹框

- parameter title: 标题

- parameter msg: 消息

- parameter btns: 弹框项

func show(title:String,msg:String,btns:[String]?) {

let alert =UIAlertController(title: title, message: msg, preferredStyle: .Alert);

for(var i=0;i<btns?.count;i++) {

let btn =UIAlertAction(title: btns![i], style: .Default) { (UIAlertAction) ->Void in

print(UIAlertAction.title);// 打印选中内容

}

alert.addAction(btn);

}

let btn =UIAlertAction(title: "取消", style:.Destructive) { (UIAlertAction) -> Voidin

var choose = -1;

}

alert.addAction(btn);

self.presentViewController(alert, animated:true,completion: nil);

}

使用方法：

let serialBar:[String] = ["类型","串口号","波特率","数据位","停止位","校验位","","类型","串口号","波特率","数据位","停止位","校验位"];

let serialBarData:[Int:[String]] = [0:["Rs232"],

1:["1","2","3","4"],

2:["9600","19200","38400","115200"],

3:["8","9"],

4:["1","1.5","2"],

5:["奇校验","偶校验","无校验"],

6:[""],

7:["Rs485"],

8:["1","2"],

9:["9600","19200","38400","115200"],

10:["8","9"],

11:["2","1.5","1"],

12:["奇校验","偶校验","无校验"],

];

上面是字典

show(serialBar[row], msg:"请选择数据", btns:serialBarData[row])

效果图： [如果只有2项，就横着排]
