PullToRefreshView
Note: I would avoid using this right now, at least until I find time to resolve a number of issues with it.
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:<your scroll view here>];
[pull setDelegate:self];
[<your scroll view here> 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.
