ios – 如何通过swift中的通知传递多个值

如何通过通知发送一个数字和一个字符串…

let mynumber=1;
let mytext="mytext";
NSNotificationCenter.defaultCenter().postNotificationName("refresh",object: ?????????????);

并接收接收器中的值？

func refreshList(notification: NSNotification){
        let receivednumber=??????????
        let receivedString=?????????
    }

解决方法

您可以将它们包装在NSArray或NSDictionary或自定义对象中.

例如：

let mynumber=1;
let mytext="mytext";

let myDict = [ "number": mynumber,"text":mytext]

NSNotificationCenter.defaultCenter().postNotificationName("refresh",object:myDict);

func refreshList(notification: NSNotification){
    let dict = notification.object as! NSDictionary
    let receivednumber = dict["number"]
    let receivedString = dict["mytext"]
}
