Question

我试图从解析中获取数据并将其呈现在表格视图中。我无法编译代码，因为这是一个错误。

这是我的代码：

import UIKit
import Parse

class EventsTableViewController: UITableViewController {

    // Array to store event timeline objects from parse
    var eventtimelineData:NSMutableArray = NSMutableArray()


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


    override func viewDidLoad() {
        super.viewDidLoad()
    }


    @IBAction func loadData(){

        // first remove the contents from the array
        eventtimelineData.removeAllObjects()

        var findTimelineData:PFQuery = PFQuery(className: "Events")

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

            // if query doesn't return any error
            if !error{
                for object:PFObject! in objects{
                    self.timelineData.addObject(object)
                }

                let array:NSArray = self.timelineData.reverseObjectEnumerator().allObjects
                self.timelineData = array as NSMutableArray

                self.tableView.reloadData()


            }

        }
    }

这是我得到的错误：

（[AnyObject] !, NSError！） - ＆gt;虚空＆＃39;不能转换为＆＃39; PFArrayResultBlock？

你可以帮我解决这个问题吗？感谢。

想出来。 Parse更新了他们的查询语法。这有效。

@IBAction func loadData(){

        // first remove the contents from the array
        eventtimelineData.removeAllObjects()


        let query = PFQuery(className:"Events")
        query.whereKey("CreatedBy", equalTo:PFUser.currentUser()!)

        query.findObjectsInBackgroundWithBlock {
            (objects, error) -> Void in

            if error == nil {
                // The find succeeded.
                print("Successfully retrieved \(objects!.count) scores.")

                // Do something with the found objects
                if let objects = objects as? [PFObject] {
                    for object in objects {

                        self.eventtimelineData.addObject(object)
                        print(object.objectId)
                        print(object.description)
                    }

                    let array:NSArray = self.eventtimelineData.reverseObjectEnumerator().allObjects
                    self.eventtimelineData = array.mutableCopy() as! NSMutableArray
                    self.tableView.reloadData()

                }


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

    }

从解析到Table View Controller获取数据
