ios - 使用handleWatchKitExtensionRequest 将数组传递给 watch 应用程序

Question

我终于设法从父应用程序获取一些数据传递到我的 Apple Watch 应用程序，但是我现在希望传递一个数组。目前我让它使用 2 个单独的字符串，但是我不知道如何让它使用 2 个数组。

这是我在 watch 应用程序中的当前代码:

func reloadTable() {
    WKInterfaceController.openParentApplication(["pfquery_request": "pfquery_request"]) { userInfo, error in
        println("User Info: \(userInfo)")
        println("Error: \(error)")

        var data = (userInfo as NSDictionary)

        if let success = data["success"] as? NSNumber {
            if success.boolValue == true {
                var name = data.objectForKey("Name") as! String
                var waitTime = data.objectForKey("WaitTime") as! String
                println(name)
            }
        }
    }
}

在父应用程序中:

func application(application: UIApplication, handleWatchKitExtensionRequest userInfo: [NSObject : AnyObject]?, reply: (([NSObject : AnyObject]!) -> Void)!) {
    if let pfqueryRequest: AnyObject = (userInfo as? [String: AnyObject])?["pfquery_request"] {
        var name = ""
        var waitTime = ""

        var query = PFQuery(className: "Park")
        var objects = query.findObjects()

        if let objects = objects as? [PFObject] {
            for object in objects {
                name = (object.objectForKey("Name") as? String)!
                waitTime = (object.objectForKey("WaitTime") as? String)!
            }

            reply(["success": true, "name": name, "waitTime": waitTime])
        }
    }
}

任何人都可以指出我正确的方向或提供一些示例代码吗？我希望传递所有对象名称和 waitTimes 的数组。

谢谢!

虽然未经测试，但应该可以工作!

if let pfqueryRequest: AnyObject = (userInfo as? [String: AnyObject])?["pfquery_request"] {
        var name : [String] = []
        var waitTime : [String] = []

        var query = PFQuery(className: "Park")
        var objects = query.findObjects()

        if let objects = objects as? [PFObject] {
            for object in objects {
                name += (object.objectForKey("Name") as? String)!
                waitTime += (object.objectForKey("WaitTime") as? String)!
            }

            reply(["success": true, "name": name, "waitTime": waitTime])
        }
    }
