When I click UISegmentedControl, make it change to UITableViewCell - swift

Question

How to call method
internal func segconChanged(segcon: UISegmentedControl, var text:String){
switch segcon.selectedSegmentIndex {
case 0:
print("whoo")
return text = "clicked Trainings"
case 1:
print("yeahh")
return text = "clicked Daily"
default:
break
}
}
from
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
?
I am beginner of swift.
I am using UISegmentedControl, and UITableView.
When I click UISegmentedControl, make it change to UITableViewCell.
Please look at inside of func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
I added segconChanged(UISegmentedControl(), text: "") to call method,
but I think this is wrong and actually doesnt work.
Please give me advice.
This is all code.
import UIKit
class TrainingLogViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
#IBOutlet weak var myTableView: UITableView!
#IBOutlet weak var segment: UISegmentedControl!
let tabLog: NSArray = ["Trainings", "Daily"]
override func viewDidLoad() {
super.viewDidLoad()
myTableView.delegate = self
myTableView.dataSource = self
segment.addTarget(self, action: "segconChanged:", forControlEvents: UIControlEvents.ValueChanged)
}
var text: String = ""
internal func segconChanged(segcon: UISegmentedControl, var text:String){
switch segcon.selectedSegmentIndex {
case 0:
print("whoo")
return text = "clicked Trainings"
case 1:
print("yeahh")
return text = "clicked Daily"
default:
break
}
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
// #warning Incomplete implementation, return the number of sections
return 10
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 10
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell{
let text: String = ""
*segconChanged(UISegmentedControl(), text: "")
let cell = UITableViewCell(style: .Subtitle, reuseIdentifier: "LogTraining")
cell.textLabel?.text = text
cell.detailTextLabel?.text = "subtitle"
return cell
}
}

You dont need to call segconChanged() function manually as it will automatically be called when segment is changed. So just reload your tableview when segment is changed, check its index and populate data acccordingly i.e. in cellForRowAtIndexPath method.
Try this code :
import UIKit
class TrainingLogViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
#IBOutlet weak var myTableView: UITableView!
#IBOutlet weak var segment: UISegmentedControl!
let tabLog: NSArray = ["Trainings", "Daily"]
override func viewDidLoad() {
super.viewDidLoad()
myTableView.delegate = self
myTableView.dataSource = self
segment.addTarget(self, action: "segconChanged:", forControlEvents: UIControlEvents.ValueChanged)
}
func segconChanged(segcon: UISegmentedControl){
self.myTableView.reloadData()
switch segcon.selectedSegmentIndex {
case 0:
print("clicked Trainings")
case 1:
print("clicked Daily")
default:
break
}
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
// #warning Incomplete implementation, return the number of sections
return 1
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 10
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell{
let cell = tableView.dequeueReusableCellWithIdentifier("LogTraining", forIndexPath: indexPath)
cell.textLabel?.text = (self.segment.selectedSegmentIndex == 0) ? tabLog[0] : tabLog[1]
cell.detailTextLabel?.text = "subtitle"
return cell
}
}
