It is:

• a pull-to-refresh implementation
• very easy to implement
• doesn't suck

To implement it:

• add the four files (PullToRefreshView.{h,m}, arrow.png and [email protected]) to your project
• add the Quartz framework to your project if you haven't done so yet
• #import "PullToRefreshView.h"
• add QuartzCore to your project
• add an ivar: PullToRefreshView *pull; // or whatever you want to name it
• in loadView or viewDidLoad, add this (and be sure to release in dealloc/viewDidUnload, etc): pull = [[PullToRefreshView alloc] initWithScrollView:]; [pull setDelegate:self]; [ addSubview:pull];
• in dealloc and viewDidUnload, add calls to: [pull containingViewDidUnload]; to unwind the view hierarchy.
• implement two delegate methods: // called when the user pulls-to-refresh
  • (void)pullToRefreshViewShouldRefresh:(PullToRefreshView *)view; // called when the date shown needs to be updated, optional
  • (NSDate *)pullToRefreshViewLastUpdated:(PullToRefreshView *)view;
• call -finishedLoading on the PullToRefreshView when you finished loading (or got an error, etc)
• that's it! no need to forward on UIScrollView delegate methods or anything silly like that.
