/*
|
|
* Returns a delegate splitter that can be used to create as many `UIScrollView` delegates as needed.
|
|
* Use that instead of accessing `delegate` property directly.
|
|
*
|
|
* This class overrides the `delegate` property and wires that to the delegate splitter.
|
|
*
|
|
* We never know which another part of the app might introspect the view hierarchy and mess with `UIScrollView`'s
|
|
* delegate, so we expose a fake delegate connected to the original one via the splitter to make the component as
|
|
* resilient to other code as possible: even if something else nil the delegate, other delegates that were subscribed
|
|
* via the splitter will continue working.
