I can't release pullView in viewDidUnload. App will CRASH if it receive memory warning.

There is a problem with pulltorefresh when you try to zoom-in the scrollview or other object
example: yfrog.com/klxvvp

I tried to add this to my tableview.
I can see the arrow on top of the tableview, but the arrow isn't rotating or anything. I think it isn't recognizing my tableview as a scrollview. How can i fix that?

The latest version (5405a50) doesn't work with UIWebView.
state never be set and pullToRefreshViewShouldRefresh never be triggered.
Adding 'state = kPullToRefreshViewStateNormal;' in initWithScrollView makes this work with UIWebView.

I implemented everything into my rss reader, but after bulling the tableview down, the loading window doesn't disappear anymore.

import "RssFunViewController.h"

import "BlogRssParser.h"

import "BlogRss.h"

import "GYSAAppDelegate.h"

@implementation RssFunViewController

@synthesize rssParser = _rssParser;
@synthesize tableView = _tableView;
@synthesize appDelegate = _appDelegate;
@synthesize toolbar = _toolbar;

-(void)toolbarInit{
UIBarButtonItem *refreshButton = [[UIBarButtonItem alloc]
initWithBarButtonSystemItem:UIBarButtonSystemItemRefresh
target:self action:@selector(reloadRss)];
refreshButton.enabled = NO;
NSArray *items = [NSArray arrayWithObjects: refreshButton, nil];
[self.toolbar setItems:items animated:NO];
[refreshButton release];
}

// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.

• (void)viewDidLoad {
  [super viewDidLoad];
  [self toolbarInit];
  _rssParser = [[BlogRssParser alloc]init];
  self.rssParser.delegate = self;
  [[self rssParser]startProcess];
  pull = [[PullToRefreshView alloc] initWithScrollView:_tableView];
  [pull setDelegate:self];
  [_tableView addSubview:pull];
  }

// called when the user pulls-to-refresh

• (void)pullToRefreshViewShouldRefresh:(PullToRefreshView *)view {
  [[self tableView]reloadData];
  }
• (void)finishedLoading {
  //reload the table view
  [[self tableView]reloadData];
  }

-(void)toggleToolBarButtons:(BOOL)newState{
NSArray *toolbarItems = self.toolbar.items;
for (UIBarButtonItem *item in toolbarItems){
item.enabled = newState;
}
}

• (void)processCompleted{
  //reload the table view
  [self toggleToolBarButtons:YES];
  [[self tableView]reloadData];
  }

//Delegate method for blog parser will get fired when the process is completed

-(void)processHasErrors{
//Might be due to Internet
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Achtung!" message:@"Leider ist es im Moment nicht möglich eine Verbindung zum Internet herzustellen."
delegate:nil cancelButtonTitle:@"OK" otherButtonTitles: nil];
[alert show];
[alert release];
[self toggleToolBarButtons:YES];
}

Hi,
Would be interesting to put it in a UIWebView.

When I use this with UIWebView, statusLabel is not showing.
Adding following code in initWithScrollView fix this issue.
statusLabel.frame = CGRectMake(0.0f, frame.size.height - 50.0f, self.frame.size.width, 20.0f);
