Can't add UITableView to UIView swift - ios

Question

I have a UIViewController with a header subview and a UITableView.
My tableView with its custom cells works perfectly when I implement it on a UITableView class, but once I try to imbed it in my UIViewController, I get the tableview frame that I see based on the different background color but it doesn't get populated with my custom cell.
My print statement in tableview (...cellForRowAtIndexPath ..) doesn't print anything, it's as if the function is not called.
I'm not sure what I'm doing wrong, any help is much appreciated!
import UIKit
class ProfileViewController: UIViewController , UITableViewDelegate, UITableViewDataSource {
var tableView: UITableView!
var header: UIView!
var userName: UILabel!
var userImage: UIImageView!
var dataDict : NSDictionary!
var cellArray: NSArray!
var friends = [Friends]()
init(dataDict: NSDictionary , nibName: String?, bundle: NSBundle?){
super.init(nibName: nibName, bundle: bundle)
self.dataDict = dataDict
}
required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
override func viewDidLoad() {
super.viewDidLoad()
cellArray = dataDict?.objectForKey("data") as! NSArray
tableView.delegate = self
tableView.dataSource = self
header = UIView(frame: CGRectZero)
header.backgroundColor = UIColor( red:77/255.0, green:255/255.0, blue:195/255.0, alpha:1.0)
userName = UILabel(frame: CGRectZero)
userName.textAlignment = .Left
userName.text = "Nachwa El khamlichi"
userName.textColor = UIColor.blackColor()
userName.frame = CGRectMake(10, 100, self.view.frame.width/2, 40)
userImage = UIImageView(frame: CGRectZero)
userImage.frame = CGRectMake(10, 30, 80, 80)
tableView.contentInset = UIEdgeInsets(top: 300, left: 0, bottom: 0, right: 0)
tableView.backgroundColor = UIColor.orangeColor()
tableView.separatorStyle = UITableViewCellSeparatorStyle.SingleLine
self.view.addSubview(header)
self.view.addSubview(userName)
self.view.addSubview(userImage)
self.view.addSubview(tableView)
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 1
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return cellArray.count
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
print(cellArray.count)
let cell = tableView.dequeueReusableCellWithIdentifier( NSStringFromClass(Cell), forIndexPath: indexPath) as! Cell
let friendName = cellArray[indexPath.row]["name"] as? String
let avatarId = cellArray[indexPath.row]["id"] as? String
friends.append(Friends(name: friendName!, avatarId: avatarId!))
cell.friend?.name = friendName
cell.friend = friends[indexPath.row]
return cell
}
func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
return 40
}
}

Answer 1

I think you forget to add
tableView = UITableView(frame: UIScreen.mainScreen().bounds, style: UITableViewStyle.Plain)
tableView.delegate = self
tableView.dataSource = self
tableView.registerClass(UITableViewCell.self, forCellReuseIdentifier: "cell")
self.view.addSubview(self.tableView)
at the same time you forget to add frame
header = UIView(frame: CGRectZero)
header.frame = CGRectMake(10, 100, self.view.frame.width/2, 40)
header.backgroundColor = UIColor( red:77/255.0, green:255/255.0, blue:195/255.0, alpha:1.0)
OPtion-2
if every thing is fine check once
your cellArray contains data available or not`,
option-3
after this line add this
self.view.addSubview(self.tableView)
tableView.reloadData()
