How to show one tableview data in two segments in swift - swift

Question

I am using XLPagerTabStrip for segment
i want to show one tableview data in two segment with sorted, for that i am using below code
SegmentViewController code: if i add child_2.isSorted = false then error
Value of type 'UIViewController' has no member 'isSorted'
import UIKit
import XLPagerTabStrip
class SegmentViewController: ButtonBarPagerTabStripViewController {
#IBOutlet weak var testSeg: ButtonBarView!
override func viewDidLoad() {
super.viewDidLoad()
// change selected bar color
// Sets the background colour of the pager strip and the pager strip item
settings.style.buttonBarBackgroundColor = .white
settings.style.buttonBarItemBackgroundColor = .yellow
// Sets the pager strip item font and font color
settings.style.buttonBarItemFont = UIFont(name: "Helvetica", size: 15.0)!
settings.style.buttonBarItemTitleColor = .gray
changeCurrentIndexProgressive = { [weak self] (oldCell: ButtonBarViewCell?, newCell: ButtonBarViewCell?, progressPercentage: CGFloat, changeCurrentIndex: Bool, animated: Bool) -> Void in
guard changeCurrentIndex == true else { return }
oldCell?.label.textColor = .gray
newCell?.label.textColor = .blue
}
// Do any additional setup after loading the view.
}
override func viewDidLayoutSubviews() {
super.viewDidLayoutSubviews()
self.buttonBarView.frame = testSeg.frame
}
override func viewControllers(for pagerTabStripController: PagerTabStripViewController) -> [UIViewController] {
let child_1 = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "SegTableViewController")
let child_2 = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "SegTableViewController")
child_2.isSorted = false
return [child_1, child_2]
}
}
SegTableViewController code: here in both segments showing only sortedArray i need in first segment sortedArray and second segment namesArray.. how to do that.. could anyone please suggest me
import UIKit
import XLPagerTabStrip
class SegTableViewController: UIViewController, UITableViewDelegate, UITableViewDataSource, IndicatorInfoProvider {
var sortedArray = [String]()
var isSorted = true
func indicatorInfo(for pagerTabStripController: PagerTabStripViewController) -> IndicatorInfo {
if isSorted{
return IndicatorInfo(title: "Sorted")
}else{
return IndicatorInfo(title: "Normal")
}
}
#IBOutlet weak var tableView: UITableView!
var namesArray = ["afsdf","ddsfsdf", "hjhgjh", "trytryr", "nvbmvnb", "yuertyri", "bmvmncb", "jgfhk", "ytuioi", "sdfgsfdsh", "mkhjgijik", "gfuyru"]
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
sortedArray = namesArray.sorted { $0.localizedCaseInsensitiveCompare($1) == ComparisonResult.orderedDescending }
self.tableView.register(UITableViewCell.self, forCellReuseIdentifier: "cell")
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if isSorted {
return sortedArray.count
}
else{
return namesArray.count
}
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell") as! UITableViewCell
if isSorted{
cell.textLabel?.text = sortedArray[indexPath.row]
}
else{
cell.textLabel?.text = namesArray[indexPath.row]
}
return cell
}
}

You need to cast your view controller like this
override func viewControllers(for pagerTabStripController: PagerTabStripViewController) -> [UIViewController] {
let child_1 = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "SegTableViewController")
let child_2 = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "SegTableViewController")
(child_2 as? SegTableViewController).isSorted = false
return [child_1, child_2]
}
Also, no need for an array for displaying data. Use only one array namesArray like this
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
if isSorted {
namesArray = namesArray.sorted { $0.localizedCaseInsensitiveCompare($1) == ComparisonResult.orderedDescending }
}
self.tableView.register(UITableViewCell.self, forCellReuseIdentifier: "cell")
}
