UITableView customization in iOS9 with Xcode

In the previous post we saw how to create a post with image and store in Parse. In this tutorial we will see how we can list all the items.

Let’s drag in a UITableViewController in the main storyboard -> go to editor embed in Navigation Controller. At this point let increase the height of the UITableViewcell set the height to 170 in the size inspector.

The next thing would be to drag the UIImageview and the label along with the button. You can download the apple pay resources here Apple pay resources. Add the necessary image to Assets in Xcode by dragging the required images into xcode. Next we will go into how we can setup the autolayouts for all the labels and the button

Here are the constraints for the UIImageView and the labels. I have intentionally left adding a few constraints. Play around to figure out the constraints and if you are confused let me know. Also note that for all the Labels if you set the content hugging and content compression property to default then xcode will tell you that it’s unable to resolve auto layout constraints.  Content Hugging and Content compression property help the auto layout system by giving priority to some elements as compared to others to  statisfy the constraints.  In our case if you see warning in the xcode try to decrease the content hugging property to the description and the price labels.

Similarly now for the UIButton . Go to the attribute inspect and change the image to the apple pay image.

Now that we have designed the UI. Lets see how we can start display the items in the UITableView.

To get started create a UITableViewCell custom class and call it TableViewCell. Go to the Main.storyboard and set the class of the UITableViewCell to the new created TableViewCell. Create IBOutlets from all the Labels and the UIImageView. Also create an IBAction from the Apple pay button to the TableViewCell and call it buy

import UIKit

class TableViewCell: UITableViewCell {

    @IBOutlet weak var itemImageView: UIImageView!
    @IBOutlet weak var title: UILabel!
    @IBOutlet weak var info: UILabel!
    @IBOutlet weak var priceLabel: UILabel!
    override func awakeFromNib() {
        // Initialization code

    override func setSelected(selected: Bool, animated: Bool) {
        super.setSelected(selected, animated: animated)

        // Configure the view for the selected state

    @IBAction func buy(sender: AnyObject) {

To map the parse object into a Domain Object we will create a new struct called Item.

//  Item.swift

import Foundation
import Parse

struct Item {
    var title: String!
    var info: String!
    var price : Double!
    var imageData : NSData!
    var thumbnailData : NSData!
    init(title: String, info: String, price : Double, imageData : NSData, thumbnailData: NSData) {
        self.title = title = info
        self.price = price
        self.imageData = imageData
        self.thumbnailData = thumbnailData
    init(obj : PFObject){
        self.title = obj.valueForKey("title") as! String = obj.valueForKey("info") as! String
        self.price = obj.valueForKey("price") as! Double
        let tfile = obj.objectForKey("itemImage") as! PFFile
        self.imageData = tfile.getData()
        let thumbfile = obj.objectForKey("thumbnailImage") as! PFFile
        self.thumbnailData = thumbfile.getData()


Create a new class which subclasses UITableViewController and call it ListViewController. Here is the code for the ListViewController

//  ListViewController.swift
//  SellAnything
//  Created by Shrikar Archak on 7/14/15.

import UIKit
import Parse

class ListViewController: UITableViewController{

    var query = PFQuery(className: "Item")
    var items :[Item]? = []
    override func viewDidLoad() {
        query.findObjectsInBackgroundWithBlock { (data: [AnyObject]?, error) -> Void in
            let objects = data as! [PFObject]
            for tmp in objects {
                self.items?.append(Item(obj: tmp))
            dispatch_async(dispatch_get_main_queue(), { () -> Void in



    override func didReceiveMemoryWarning() {


    // MARK: - Table view data source

    override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
        return 1

    override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        if let titems = items {
            print("REturning \(titems.count)")
            return titems.count
        return 0

    override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath) as! TableViewCell
        let item = self.items![indexPath.row]
        cell.itemImageView.image = UIImage(data: item.imageData)
        cell.title.text = item.title =
        cell.priceLabel.text = "$\(item.price)"
        print("Got some data")
        return cell
