Current index inside child class.

[vanjaruzic]

How to get current index inside child class, which, in my case, inherits UITableViewController?
Other answers for similar questions didn't helped me...

Thanks for help in advance, cheers.

Use

public var changeCurrentIndexProgressive: ((_ oldCell: ButtonBarViewCell?, _ newCell: ButtonBarViewCell?, _ progressPercentage: CGFloat, _ changeCurrentIndex: Bool, _ animated: Bool) -> Void)?

inside your PagerVC viewDidLoad. Inside closure you can get child's current index every time.

Example:

override func viewDidLoad() {
        super.viewDidLoad()
        
        changeCurrentIndexProgressive = { (oldCell: ButtonBarViewCell?, newCell: ButtonBarViewCell?, progressPercentage: CGFloat, changeCurrentIndex: Bool, animated: Bool) -> Void in
            guard changeCurrentIndex == true else { return }

            print(self.currentIndex)

        }
    }

            print(self.currentIndex)

        }
    }

print(self.currentIndex) it is returning some random indexes, not working
