I am Working on Tab like android in iOS
Swift3
. I have installed XLPagerTabStrip
successful but facing problem:
terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'Storyboard () doesn't contain a view controller with identifier 'child1'
Here is my Code:
import UIKit
import XLPagerTabStrip
class ParentViewController: ButtonBarPagerTabStripViewController {
let customPurpleColor = UIColor(red:0.13 , green : 0.03 , blue : 0.25 , alpha : 1.0)
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
settings.style.buttonBarBackgroundColor = .white
settings.style.buttonBarItemBackgroundColor = .white
settings.style.selectedBarBackgroundColor = customPurpleColor
settings.style.buttonBarItemFont = .boldSystemFont(ofSize: 14)
settings.style.selectedBarHeight = 1.0
settings.style.buttonBarMinimumLineSpacing = 0
settings.style.buttonBarItemTitleColor = .black
settings.style.buttonBarItemsShouldFillAvailiableWidth = true
settings.style.buttonBarLeftContentInset = 0
settings.style.buttonBarRightContentInset = 0
changeCurrentIndexProgressive = { [weak self] (oldCell : ButtonBarViewCell? , newCell : ButtonBarViewCell?
, progressPercentage: CGFloat, changeCurrentIndex : Bool , animated : Bool) -> Void in
guard changeCurrentIndex == true else {return}
oldCell?.label.textColor = .black
newCell?.label.textColor = self?.customPurpleColor
}
}
override func viewControllers(for pagerTabStripController: PagerTabStripViewController) -> [UIViewController] {
let child_1 = UIStoryboard(name : "Main" , bundle : nil).instantiateViewController(withIdentifier: "child1")
let child_2 = UIStoryboard(name : "Main" , bundle : nil).instantiateViewController(withIdentifier: "child2")
return [child_1 , child_2]
}
}
ChildViewController1.swift:
import UIKit
import XLPagerTabStrip
class ChildViewController1: UIViewController , IndicatorInfoProvider{
func indicatorInfo(for pagerTabStripController: PagerTabStripViewController) -> IndicatorInfo {
return IndicatorInfo(title : "child1")
}
}
ChildViewController2.swift:
import UIKit
import XLPagerTabStrip
class ChildViewController2: UIViewController , IndicatorInfoProvider{
func indicatorInfo(for pagerTabStripController: PagerTabStripViewController) -> IndicatorInfo {
return IndicatorInfo(title : "child1")
}
}
I have used the UIScrollView
and collectionView
to buttonBarView in Main.storyboard
. Because I am new to iOS Development that's why I'm not getting why this error occurs?
