Join Bill Weinman for an in-depth discussion in this video Pull to refresh, part of iOS App Development: Building Data-Driven Apps with SQLite.
- We now have a complete working application…but there's still a few simple features…that would be nice to add.…For example, it'd be nice to be able to refresh a feed.…iOS has a nice poll to refresh feature…that was added in iOS 6.…It's simple to implement.…Here I have opened a working copy of BWRSS-Refresh-01…from chapter nine of the Exercise Files.…And we're going to our ItemsViewController here…and we're going to start by adding…a method for the refresh control.…And so I'm gonna add it here…just before the Support functions.…
You notice these comments that say MARK in them.…That's what gives these list here, its subheadings.…And so I'm gonna add just another one.…It's a nice thing to do.…MARK, it has to be all caps.…And this is a Swift feature.…In Objective-C, it actually looks like this,…pragma mark.…Here we are in ItemsViewController.…I'm gonna say MARK:…UIRefreshControl…and then we'll create a function…and it will be called doRefresh.…
And it requires a parameter here,…sender: UIRefreshControl.…And I like a little space there sometimes.…
