Add support to manually trigger infinite scroll

pronebird commented 7 years ago

Changes:

Added new method to start infinite scroll programmatically using beginInfiniteScroll(forceScroll). When forceScroll = true scroll view scrolls down to reveal indicator view.
After loading initial data scroll view returns user back to top.
beginInfiniteScroll won't scroll down during user interaction with scroll view, but will silently fire handler block.
Added infinite scroll interactions on empty scroll views.
Improved scroll to bottom which should work fine for self-sizing cells in UITableViews.

Known issues:

iOS simulator 10.2 from Version 8.2 beta (8C23) has some issues with content offset, but everything works fine on earlier simulators or device with latest iOS 10.

Awesome! I'm going to be implementing this in a new feature in one of our apps. I'll let you know how it fares.

@mikengyn any news? I am going to test it with 10.2 just in case.

mikengyn commented 7 years ago

@pronebird I did a quick test run on 10.2 on an app and seems to work without experiencing any issues! What are the issues with contentOffsets that you were having?

pronebird commented 7 years ago

@mikengyn cool thanks for testing! Content offset animations were kind of snappy, but that was happening on beta of Xcode. I don't see that happening anymore on the latest Xcode 8.2
