dead simple pull to refresh
PullToRefreshView 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 QuartzCore framework to your project if you haven't done so yet - #import "PullToRefreshView.h" - 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]; - 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. To use with a web view: pullToRefreshView = [[PullToRefreshView alloc] initWithWebView:<your web view here>]; [pullToRefreshView setDelegate:self]; [pullToRefreshView.scrollview addSubview:pullToRefreshView]; To dismiss the view after a certain period, even if finishedLoading isn't called: pullToRefreshView.timeout = 5; // 5 seconds To customize the appearance, edit the statusLabel, lastUpdatedLabel, activityView, and arrowImage properties: pullToRefreshView.statusLabel.textColor = [UIColor whiteColor]; pullToRefreshView.statusLabel.shadowColor = [UIColor lightGrayColor]; pullToRefreshView.lastUpdatedLabel.textColor = [UIColor whiteColor]; pullToRefreshView.lastUpdatedLabel.shadowColor = [UIColor lightGrayColor]; pullToRefreshView.activityView.color = [UIColor lightGrayColor]; pullToRefreshView.arrowImage.contents = (id) [UIImage imageNamed:@"my_arrow"].CGImage; To customize the content, edit the pullToRefreshText, releaseToRefreshText, loadingText, and dateFormatter properties: pullToRefreshView.pullToRefreshText = @"Pull up to load more stories..."; pullToRefreshView.releaseToRefreshText = @"Release to refresh stories..."; pullToRefreshView.loadingText = @"Refreshing stories..."; NSDateFormatter *formatter = [[[NSDateFormatter alloc] init] autorelease]; formatter.dateStyle = NSDateFormatterShortStyle; formatter.timeStyle = NSDateFormatterNoStyle; pullToRefreshView.dateFormatter = formatter;
