2,358 PointsControl TableView with Segment Control (reloadData-Issue)
Hey HappyTreeFriends, I created a Tableview which loads an array of tuples from another .swift file. That is working fine! Now I want the tableview to choose the .swift based on a "segment control". So if the Segment-Control is switched to "A" I want it to show the Array of "PSShortCutsBook.Swift", for B it would be the Array of "PSShortCutsBook2.swift".
The Action ist written properly, I guess (print-statements are working). But the change of the segment-control doesn't effect the Tableview. I added a reloaded the Data but still nothing happens. It won't refresh! Can anyone Tell me what I am doing wrong?
Thanks!
Here is the Code:
import UIKit
class ViewController: UIViewController, UITableViewDataSource {
var PSSCBook = PSShortCutsBook()
@IBOutlet weak var SCOutlet: UISegmentedControl!
@IBOutlet weak var SCtableviewOutlet: UITableView!
@IBAction func SCAction(sender: AnyObject) {
if SCOutlet.selectedSegmentIndex == 1 {
var PSSCBook = PSShortCutsBook()
println("There are \(PSSCBook.shortCutsPS.count) items in this Array")
self.SCtableviewOutlet.reloadData();
} else {
var PSSCBook = PSShortCutsBook2()
println("There are \(PSSCBook.shortCutsPS.count) items in this Array")
self.SCtableviewOutlet.reloadData();
}
}
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
return 2
}
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if section == 0 {
return PSSCBook.shortCutsPS.count
} else {
return PSSCBook.shortCutsPS2.count
}
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
var cell = tableView.dequeueReusableCellWithIdentifier("PSCell", forIndexPath: indexPath) as! UITableViewCell
if indexPath.section == 0 {
let (shortCutTitle,shortCutKey) = PSSCBook.shortCutsPS[indexPath.row]
cell.textLabel?.text = shortCutTitle
cell.detailTextLabel?.text = shortCutKey
} else {
let (shortCutTitle,shortCutKey) = PSSCBook.shortCutsPS2[indexPath.row]
cell.textLabel?.text = shortCutTitle
cell.detailTextLabel?.text = shortCutKey
}
return cell
}
func tableView(tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
if section == 0 {
return "Tools"
} else {
return "Help"
}
