推荐答案

你可以将它们包装成一个 NSArray 或 NSDictionary 或自定义对象。

You could wrap them in an NSArray or a NSDictionary or a custom Object.

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"]
}
