TOScrollBar is a UI component that can be inserted into UIScrollView instances, allowing the user to traverse the entire scroll view in one swiping gesture.
It has been designed to appear and behave like a standard system control, and has been optimized to ensure it has minimal impact on scroll performance.
- Allows for fine-grained scrolling of a
UIScrollView's entire content height. - Interoperates directly with
UIScrollViewthrough the Objective-C runtime and KVO. - Animates the same way as the standard scroll indicators (including rubber banding).
- Exposes 44 points of horizontal touch space, so it is very easy to activate.
- Tapping at different positions allows for instant traversal along the scroll view.
- Plays a scrolling animation during slow swiping, making it easier to follow along.
- Comes with initial style settings for dark themes.
- Includes Taptic Engine impact effects in a similar style to
UISlider, available on iPhone 7.
TOScrollBar has been designed to be added directly to a UIScrollView, not as a view above.
// Create a scroll bar object
TOScrollBar *scrollBar = [[TOScrollBar alloc] init];
// Add the scroll bar to our table view
[self.tableView to_addScrollBar:scrollBar];
//Adjust the table separators so they won't underlap the scroll bar
self.tableView.separatorInset = [self.tableView.to_scrollBar adjustedTableViewSeparatorInsetForInset:self.tableView.separatorInset];
Once added to a scroll view, a scroll bar can be accessed via the to_scrollBar property. Convienience methods are
also applied to make it easier to configure the margins
TOScrollBar will work with iOS 7 and above. While written in Objective-C, it should easily import into Swift as well.
Copy the contents of the TOScrollBar folder to your app project.

I'm building a comic reader app that allows users to group collections of comics into single view controllers.
Unfortunately, some users have reported that certain comic series have a very large number of issues. It doesn't make sense to break these issues out of their collections, but at the same time, traversing the comic has become a gruelling process.
This scroll bar is the first component in a series of upgrades I'm planning in an attempt to make navigation large comic collections more manageable.
TOScrollBar was created by Tim Oliver as a component of iComics.
