我正在尝试从Parse获取一系列PFObjects [PFObject]
并查看下面的问题。我错过了什么?
错误是呼叫
中缺少参数#1的参数func loadData() {
rooms = [PFObject]()
users = [PFUser] ()
self.tableView.reloadData()
let pred = NSPredicate(format: "user1 = %@ OR user2 = %@", PFUser.currentUser()!, PFUser.currentUser()!)
let roomQuery = PFQuery(className: "Rooms", predicate: pred)
//gives us all the information - includeKey all columns for the user class itself
roomQuery.includeKey("user1")
roomQuery.includeKey("user2")
roomQuery.findObjectsInBackgroundWithTarget{ (results: [AnyObject]!, error: NSError!) -> Void in
if error == nil {
self.rooms = results as [PFObject]
for room in self.rooms {
let user1 = room.objectForKey("user1") as PFUser
let user2 = room.objectForKey("user2") as PFUser
if user1.objectId != PFUser.currentUser() {
self.users.append(user1)
}
if user2.objectId != PFUser.currentUser() {
self.users.append(user2)
}
}
self.tableView.reloadData()
}
}
}
错误:
答案 0 :(得分:3)
您似乎想要使用块来处理响应,但您决定使用findObjectsInBackgroundWithTarget
。你应该使用findObjectsInBackgroundWithBlock:。所以你应该有这样的东西:
roomQuery.findObjectsInBackgroundWithBlock {(objects: [AnyObject]?, error: NSError?) -> Void in
