Retrieving user's Info from firebase based on project name and Details-Swift Project

Question

Here's the dashboard structure with some of the users for an iOS application using swift and firebase:

{
"users" : {
"0a0462bb-86a1-4140-bda2-90a62236ab1e" : {
  "Picker" : "Jeddah",
  "details" : "I'm here",
  "email" : "y@gmail.com",
  "name" : "y",
},
"0b71693a-4f16-4759-acd6-706da1a466a0" : {
  "Picker" : "Jubail",
  "details" : "iOS second",
  "email" : "Siham0@gmail.com",
  "name" : "Siham",
},
"0b71693a-4f16-4759-acd6-706da1a466a0" : {
  "Picker" : "Jeddah",
  "details" : "",
  "email" : "roro0@gmail.com",
  "name" : "roro",
}
 }
} 

As in the picture bellow:

The table view in the simulator contains the name and the details for all of the users whose picker is Jeddah.

What I want now is to retrieve the name, email and details in labels in another view controller whenever the user clicks at any cell!

For example, If I clicked on the first cell, the second view controller will have the following:

Name: y

Details:I'm here

Email: y@gmail.com

What should I do to make that work? And What's the structure of retrieving function should I use?

Answer 1

I did make a array of all listing value by easy format and display list of item like following:

var namesArray : NSMutableArray = []

And it's viewDidLaod Method look like following:

 override func viewDidLoad() {
        super.viewDidLoad()



        ref.queryOrderedByChild("Picker").queryEqualToValue("Makkah")
                    .observeSingleEventOfType(.Value, withBlock: { snapshot in


                        if let dict = snapshot.value as? NSMutableDictionary{
                            print("print \(dict)")


                            for (key,value) in dict {
                                 let mainDict = NSMutableDictionary()
                                mainDict.setObject(key, forKey: "userid")


                                 if let dictnew = value as? NSMutableDictionary{

                                    if let metname = dictnew["name"] as? String
                                    {
                                        mainDict.setObject(metname, forKey: "name")

                                    }
                                    if let metname = dictnew["Picker"] as? String
                                    {
                                        mainDict.setObject(metname, forKey: "Picker")

                                    }
                                    if let metname = dictnew["details"] as? String
                                    {
                                        mainDict.setObject(metname, forKey: "details")

                                    }
                                    if let metname = dictnew["email"] as? String
                                    {
                                        mainDict.setObject(metname, forKey: "email")

                                    }
                                    if let metname = dictnew["provider"] as? String
                                    {
                                        mainDict.setObject(metname, forKey: "provider")

                                    }

                                }
                                self.namesArray.addObject(mainDict)
                        }

                            print("arrayt is \(self.namesArray)")


                    }

                        self.CookingTableView.reloadData()
                        })


    }

And its array Show in TableView's cellForRowAtIndexPath must be have following code:

 func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

        let cell = self.CookingTableView.dequeueReusableCellWithIdentifier("CookingCell", forIndexPath: indexPath) as! CookingTableViewCell

        if let name = namesArray[indexPath.row] as? NSMutableDictionary{

             cell.BusinessNameLabel?.text = name["name"] as? String
            cell.DescriptionLabel?.text = name["details"] as? String
        }

        cell.accessoryType = UITableViewCellAccessoryType.DisclosureIndicator

        return cell

    }

Now the listing thing is complete. Let display its details on didSelectRowAtIndexPath Method:

 func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {


                 tableView.deselectRowAtIndexPath(indexPath, animated: true)
                 dispatch_async(dispatch_get_main_queue()) { [unowned self] in

                    let DetailsViewController = self.storyboard!.instantiateViewControllerWithIdentifier("ProjectDetailsViewController") as! ProjectDetailsViewController

                    if let name = self.namesArray[indexPath.row] as? NSMutableDictionary{

                        DetailsViewController.self.strUserid = name["userid"] as? String
                    }


                    self.navigationController?.pushViewController(DetailsViewController, animated: true)

        }
    }

Here above didSelect method i Pass the userID that unique user id need to get it's details in PushedViewController. You can also send selected items's wall dictionary to nextviewController but i do with called firebase query method in nextViewController so the nextViewController code look like:

var strUserid : NSString!

And it's ViewDidLoad:

 override func viewDidLoad() {
        super.viewDidLoad()

        print("idis \(self.strUserid)")


      ref.childByAppendingPath(self.strUserid as String).observeEventType(.Value, withBlock: { snapshot in


         if let dict = snapshot.value as? NSMutableDictionary{

            print("dict is \(dict)")

            if let name = dict["name"] as? String
            {
               self.Name.text = name

            }

            if let details = dict["details"] as? String
            {
                self.Details.text = details

            }

            if let email = dict["email"] as? String
            {
                self.Email.text = email

            }

        }



            })
    }

That's It Hope your issue going to be solve. I did this type of approach with above way.
