无法调用findObjectsInBackgroundWithBlock快速错误 [英] Cannot invoke findObjectsInBackgroundWithBlock swift error

问题描述

因此，在将所有用户都解析到我的应用程序时，我遇到了此错误:

So I ran into this error when getting all the users from parse to my application:

无法通过参数列表调用'findObjectsInBackgroundWithBlock' 类型为((([[AnyObject] !, NSError！)-> Void)'

Cannot invoke 'findObjectsInBackgroundWithBlock' with an argument list of type '(([AnyObject]!, NSError!) -> Void)'

尝试运行此代码:

    var userQuery = PFUser.query()
    userQuery.findObjectsInBackgroundWithBlock({(objects: [AnyObject]!, error: NSError!) -> Void in


        self.users.removeAll(keepCapacity: true)

        for object in objects {
            var user:PFUser = object as PFUser

            self.users.append(user.username)
        }

        self.tableView.reloadData()


    })

我正在使用xcode 6.3，有什么解决方案吗?我尝试添加?"代替 "！"在[AnyObject]之后，但似乎无济于事.

I am using xcode 6.3, is there any solutions? I've tried adding "?" instead of "!" after [AnyObject] but nothing seems to help.

推荐答案

我实际上是通过执行这样的编码来使其工作的

I actually got it working with doing the coding like this

var data: Void? = query?.findObjectsInBackgroundWithBlock({(objects:[AnyObject]?, error:NSError?) -> Void in
        self.users.removeAll(keepCapacity: true)

            for object: AnyObject in objects! {
            var user:PFUser = object as! PFUser
            self.users.append(user.username!)
        }
        self.tableView.reloadData()
    })
