致命错误：从解析中检索数据时，数组索引超出范围

Question

我收到错误：＆＃34;致命错误：数组索引超出范围＆＃34;从我的单元格中的解析中检索数据。而我奇怪的是我在不同的类中使用相同的代码，但我可以检索数据（但不准确）

它在这里给我错误（在cellForRowAtIndexPath方法中） self.profileFile [indexPath.row] .getDataInBackgroundWithBlock（{（imageData，error） - ＆gt; Void in

我有5个对象，所以如果删除这行，我可以打印5个对象。

我不知道为什么它会在这里给我错误。

var user = PFUser.currentUser()

var friends = [String]()
 var profileFile = [PFFile]()



override func viewDidLoad() {
    super.viewDidLoad()

    //friends
    var query = PFQuery(className:"Requests")
    //query.orderByDescending("requestBy")
    query.whereKeyExists("requestTo")
    query.whereKey("requestBy", equalTo: PFUser.currentUser()!.username!)

    query.findObjectsInBackgroundWithBlock {
        (objects: [AnyObject]?, error: NSError?) -> Void in

        if error == nil {
            // The find succeeded.
            println("Friends recieved \(objects!.count) scores.")
            // Do something with the found objects
            if let objects = objects as? [PFObject] {
                for object in objects {
                    println(object)
                    self.friends.append(object["requestTo"] as! String)
                    println(self.friends)
                }

            } else {
                // Log details of the failure
                println("Error: \(error!) \(error!.userInfo!)")
            }

        }
        self.tableView.reloadData()
    }
}
override func viewDidAppear(animated: Bool) {

}

override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
    // #warning Potentially incomplete method implementation.
    // Return the number of sections.
    return 1
}

override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    // #warning Incomplete method implementation.
    // Return the number of rows in the section.
    return friends.count
}


override func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
    return 65
}


override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let myCell1 = tableView.dequeueReusableCellWithIdentifier("friendCell") as! friendsTableViewCell

    myCell1.friendLabel.text = friends[indexPath.row]

    var query = PFQuery(className: "image")
    query.whereKeyExists("imageFile")
    query.whereKey("userName", equalTo : myCell1.friendLabel.text!)

    query.findObjectsInBackgroundWithBlock { (objects, error) -> Void in
        if error == nil {
            for object in objects!{
                self.profileFile.append(object["imageFile"] as! PFFile)

                self.profileFile[indexPath.row].getDataInBackgroundWithBlock({ (imageData, error) -> Void in
                    if error == nil {
                        let image = UIImage(data: imageData!)

                        myCell1.profielPic.image = image
                    }
                })
            }
        }
        self.tableView.reloadData()
    }
    //println(indexPath.row)

    return myCell1
