Unfortunately you can't, of course you can always roll your own. These are your options:

UIScrollViewIndicatorStyleDefault:

The default style of scroll indicator, which is black with a white border. This style is good against any content background.

UIScrollViewIndicatorStyleBlack:

A style of indicator which is black and smaller than the default style. This style is good against a white content background.

UIScrollViewIndicatorStyleWhite:

A style of indicator is white and smaller than the default style. This style is good against a black content background.

How to change the scroll indicator inset for a UIScrollView, How can we change color of UIScrollview's scroll indicator to something like blue, green etc. I know we can change it to white, black. But other then these colors. Scrollbar will automatically use CupertinoScrollbar under the hood on iOS now. So no you can't change the color of the scrollbar on iOS without modifying the source code. This seems like something we shouldn't officially support unless iOS supports it, so I'm going to close this issue.


Here's more safe Swift 3 method:

    let verticalIndicator = scrollView.subviews.last as? UIImageView
    verticalIndicator?.backgroundColor = UIColor.green
}

How to change the scroll indicator inset for a UIScrollView Changing this value adds a tiny bit of UI polish and it's easy to do: Safari, App Store, watchOS, tvOS, Mac and macOS are trademarks of Apple Inc., registered in the U.S. and other countries. scrollbar-color accepts the following values: auto is the default value and will render the standard scrollbar colors for the user agent. dark will tell the user agent to use darker scrollbars to match the current color scheme. light will tell the user agent to use lighter scrollbars to match the current color scheme. <color> specifies two colors to be used for the scrollbar. The first color is for the “thumb” or the moveable part of the scrollbar which appears on top.


Both UIScrollView indicator are sub view of UIScrollView. So, we can access subview of UIScrollView and change the property of subview.

1 .Add UIScrollViewDelegate

@interface ViewController : UIViewController<UIScrollViewDelegate>
@end

2. Add scrollViewDidScroll in implementation section

-(void)scrollViewDidScroll:(UIScrollView *)scrollView1
{
    //get refrence of vertical indicator
    UIImageView *verticalIndicator = ((UIImageView *)[scrollView.subviews objectAtIndex:(scrollView.subviews.count-1)]);
    //set color to vertical indicator
    [verticalIndicator setBackgroundColor:[UIColor redColor]];


    //get refrence of horizontal indicator
    UIImageView *horizontalIndicator = ((UIImageView *)[scrollView.subviews objectAtIndex:(scrollView.subviews.count-2)]);
    //set color to horizontal indicator
    [horizontalIndicator setBackgroundColor:[UIColor blueColor]];
}

Note:- Because these indicator update every time when you scroll (means reset to default). SO, we put this code in scrollViewDidScroll delegate method.
