Inside UITableView cell how to display the specified array data - ios

Question

I am new to Swift and I am trying to create Tableview in which I have only 3 Rows (Morning, Afternoon, and Night). If I click on the Morning row my cell must expand. It must display keynumber number of user whose time 8 - 12. Same for Afternoon and Night.
I have specified array data of User[] in which keynumber, time and other data are there.
I tried to do with if condition in cellForRowAtIndexPath but it displays only one user key for the Morning row. It doesn't display another users key in that particular time limit.

Answer 1

Try This
class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
#IBOutlet var tableView: UITableView!
var items: [String] = ["We", "Heart", "Swift"]
override func viewDidLoad() {
super.viewDidLoad()
self.tableView.registerClass(UITableViewCell.self, forCellReuseIdentifier: "cell")
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return self.items.count;
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
var cell:UITableViewCell = self.tableView.dequeueReusableCellWithIdentifier("cell") as UITableViewCell
cell.textLabel?.text = self.items[indexPath.row]
return cell
}
func tableView(tableView: UITableView!, didSelectRowAtIndexPath indexPath: NSIndexPath!) {
print("You selected cell #\(indexPath.row)!")
}
}
Hope this helps.

Have a try, works like a charm here
struct User {
var keynumber: Int
var time: NSData
}
class TableViewController: UITableViewController {
var userArr : Array<User> = [] //raw user data
var sortedUser : [String : Array<User>] = ["Morning": [], "Afternoon": [], "Night": []]
var sectionStatusArr : [String: Bool] = ["Morning": false, "Afternoon": false, "Night": false] // section status array used to control expanding
override func viewDidLoad() {
super.viewDidLoad()
//classify user into corresponding group(time zone)
for _ in 0...19 {
let randomKey = Int( arc4random()%23)
let user = User(keynumber: randomKey, time: NSData())
userArr.append(user)
}
//sort user: 8-12 -> morning, 13-18 -> afternoon, 19-8 -> night
for user in userArr{
switch user.keynumber {
case 8,9,10,11,12:
sortedUser["Morning"]?.append(user)
case 13,14,15,16,17,18:
sortedUser["Afternoon"]?.append(user)
default:
sortedUser["Night"]?.append(user)
}
}
}

var rowcount = 0
var shouldExpandSection = false
