对象Xcode6.3‘[AnyObject]’中的对象的Swift？没有名为“Generator”的成员

Question

Xcode6.3 'AnyObject?‘没有名为“Generator”的成员

来自此行的错误"for object2 in objects2{“

            let findImage:PFQuery = PFQuery(className: "_User")
            findImage.whereKey("objectId", containedIn: self.userlist as [AnyObject])
            findImage.findObjectsInBackgroundWithBlock{
                (objects2:[AnyObject]?, error2:NSError?)->Void in
                //var recordProfileImg:NSMutableArray = NSMutableArray()
                if !(error2 != nil){
                    for object2 in objects2{
                        println(objects2.count)
                        let sweet:PFObject = object2 as PFObject
                        if sweet.objectForKey("profileImage") != nil{
                            var recordProfileImg:NSMutableArray = [sweet.objectId,sweet.objectForKey("profileImage") as PFFile]
                            self.userImageList.addObject(recordProfileImg)

                            // println(userImageList)
                        }
                    }
                }
            }

Answer 1

由于objects2是可选的，因此必须将其解包。如果你确定它不会是空的，试试这个：

for object2 in objects2! {

Answer 2

使用！在您的数组之后：

for info in array! {

        }
