Add a vertical UIScrollView into another vertical UIScrollView on iOS. It makes users feel like it's a single UIScrollView. This tool resolve the gesture conflict between thw two UIScrollViews.

How it works: Hook the scrollViewDidScroll method of a UIScrollView by SwiftHook, calculate and reset the offset of the UIScrollView.

It supports Swift and Objective-C

Just one line code to do it!

outerScrollView.embeddedScrollView = embeddedScrollView

The API is in an extension.

extension UIScrollView {

    @objc public var embeddedScrollView: UIScrollView?
}

EmbeddedScrollView can be integrated by cocoapods.

pod 'EmbeddedScrollView'
