在Parse闭包之外更新变量

Question

我有一个变量，我希望在闭包内更新并在其外部访问。但是，我正努力将数据从关闭中解脱出来。我之前已经做好了，但忘记了我是怎么做到的。

这是我的代码：

let query = PFUser.query()
    query?.whereKey("phoneNumber", containedIn: myContactsPhoneNumbers as [AnyObject])
    query?.findObjectsInBackgroundWithBlock({ (objects, error) -> Void in

        for existingUser in objects! {
            self.contactsOnApp.append(existingUser)
        }
    })

Answer 1

//write one function to use upadated values , call the function from closure.

let query = PFUser.query()
query?.whereKey("phoneNumber", containedIn: myContactsPhoneNumbers as [AnyObject])
query?.findObjectsInBackgroundWithBlock({ (objects, error) -> Void in

    for existingUser in objects! {
        self.contactsOnApp.append(existingUser)
    }
    self.functionToUseUpadatedData(self.contactsOnApp)
})

func functionToUseUpadatedData(data: AnyObject) {
   NSLog("implementation write here")
}
