PullToRefreshView
It is:
- a pull-to-refresh implementation
- very easy to implement
- doesn't suck
To implement it:
- add the three files (PullToRefreshView.{h,m} and arrow.png) to your project
- #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.
Fork by iStopped :) In order to use this class with a UIWebView
- add the three files (PullToRefreshView.{h,m} and arrow.png) to your project
- #import "PullToRefreshView.h"
- in loadView or viewDidLoad add this:
UIWebView *webView = [[[UIWebView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)] autorelease];
webView.delegate = self;
webView.tag = 999;
NSURLRequest *request;
//fill request
[webView loadRequest:request];
[webView setScalesPageToFit:YES];
UIScrollView* currentScrollView;
for (UIView* subView in webView.subviews) {
if ([subView isKindOfClass:[UIScrollView class]]) {
currentScrollView = (UIScrollView *)subView;
currentScrollView.delegate = self;
}
}
PullToRefreshView *pull = [[[PullToRefreshView alloc] initWithScrollView:currentScrollView] autorelease];
[pull setDelegate:self];
pull.tag = 998;
[currentScrollView addSubview:pull];
[self.view addSubview:webView];
- Add the delegate -(void)pullToRefreshViewShouldRefresh:(PullToRefreshView *)view;:
-(void)pullToRefreshViewShouldRefresh:(PullToRefreshView *)view {
[(UIWebView *)[self.view viewWithTag:999] reload];
}
- Add the delegate -(void)webViewDidFinishLoad:(UIWebView *)webView;:
-(void)webViewDidFinishLoad:(UIWebView *)webView
{
[(PullToRefreshView *)[self.view viewWithTag:998] finishedLoading];
}
- Have Fun ;)
