Change width and colour of scroll bar in UITableView, iphone

Question

I could only find if one wants to display scroll bar or not using

tableView.showsVerticalScrollIndicator = YES/NO;

but how can I customize

Answer 1

I did'n find any other way but this:

UITableView *v;
[v setIndicatorStyle:<#(UIScrollViewIndicatorStyle)#>];

There is only 3 available styles. If only you will find the way to implement your own UIScrollViewIndicatorStyle, but I can't even imagine HOW to do this: they are implemented deep in UIKit framework (declared in UIScrollView.h), and you can only set a flag, witch will used by UIScrollView to know, what style to use. So, I can't see any other way: you will need somehow to implement new style and flag there. Is it possible at all?

Answer 2

You can hide the original scroll bar and scroll using your custom scroll bar.

– (void)setContentOffset:(CGPoint)contentOffset animated:(BOOL)animated 

can be used to scroll content, just add your custom bar to the table.

Answer 3

For Swift 3

collectionView.indicatorStyle = UIScrollViewIndicatorStyle.white

Answer 4

change indicator color with 3 default color style.

TextField.indicatorStyle=UIScrollViewIndicatorStyleWhite;

Answer 5

You can change the scroll indicator color using:

tableView.indicatorStyle=UIScrollViewIndicatorStyleWhite;

Hope this helps.

Answer 6

Swift-3,4

If you are not able to override method "scrollViewDidScroll" (may be you are using this for some other functionality, or paging), Try this !!

func setScrollIndicatorColor(color: UIColor) {
        for view in self.tableView.subviews {
            if view.isKind(of: UIImageView.self),
                let imageView = view as? UIImageView,
                let _ = imageView.image  {
                imageView.image = nil
                view.backgroundColor = color
            }
        }

        self.tableView.flashScrollIndicators()
    }

in viewDidAppear() you can call this method.
