# Whats different on this fork: - Easy integration, the table view can be added and configured using interface builder. - Easy configuration, the arrow image, background color and text color can simply be changed by properties of the PullTableView class. - *Pull to reload more data* functionality at the bottom of the table. - Possibility to trigger the *refreshing* and *loading more* animations by code. # The fast setup: - Add QuartzCore.framework to your project - Drag drop EGOTableViewPullRefresh directory to your project. - Look at the PullTableView.h file for available properties. - Add a PullTableView to your code and implement the PullTableViewDelegate methods. - Enjoy! # The detailed setup (Walk through for creating the demo project): - Create a new Xcode project - Choose *View Based Application* - Product name: EGOTableViewPullRefreshDemo - Create it in desired folder - Add *QuartzCore.framework* to the project **Adding the PullTableView to the project:** - Drag drop EGOTableViewPullRefresh directory to the Supporting Files group in the project, make sure items are copied into destination groups folder. **Adding the PullTable to the view `EGOTableViewPullRefreshDemoViewController.xib`:** - Drag drop a UITableView to the view. - Open the *Identity inspector* and change the Class from 'UITableView' to PullTableView - Connect the dataSource and pullDelegate outlets of the PullTableView to File's owner **Configuring view controller Header `EGOTableViewPullRefreshDemoViewController.h`:** - Add `#import "PullTableView.h"` - Make it conform to PullTableViewDelegate and UITableViewDataSource - Create an outlet property named pullTableView and connect it to the table in interface builder. **Configuring view controller Footer `EGOTableViewPullRefreshDemoViewController.m`** - Add the following code to the m file. #pragma mark - Refresh and load more methods - (void) refreshTable { /* Code to actually refresh goes here. */ self.pullTableView.pullLastRefreshDate = [NSDate date]; self.pullTableView.pullTableIsRefreshing = NO; } - (void) loadMoreDataToTable { /* Code to actually load more data goes here. */ self.pullTableView.pullTableIsLoadingMore = NO; } #pragma mark - UITableViewDataSource - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 5; } - (NSInteger) tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return 10; } - (UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *cellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier]; if(!cell) { cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier]; } cell.textLabel.text = [NSString stringWithFormat:@"Row %i", indexPath.row]; return cell; } - (NSString *) tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section { return [NSString stringWithFormat:@"Section %i begins here!", section]; } - (NSString *) tableView:(UITableView *)tableView titleForFooterInSection:(NSInteger)section { return [NSString stringWithFormat:@"Section %i ends here!", section]; } #pragma mark - PullTableViewDelegate - (void)pullTableViewDidTriggerRefresh:(PullTableView *)pullTableView { [self performSelector:@selector(refreshTable) withObject:nil afterDelay:3.0f]; } - (void)pullTableViewDidTriggerLoadMore:(PullTableView *)pullTableView { [self performSelector:@selector(loadMoreDataToTable) withObject:nil afterDelay:3.0f]; } - For UI configuration add the following code inside viewDidLoad self.pullTableView.pullArrowImage = [UIImage imageNamed:@"blackArrow"]; self.pullTableView.pullBackgroundColor = [UIColor yellowColor]; self.pullTableView.pullTextColor = [UIColor blackColor]; - For manually triggering animation use the pullTableIsRefreshing and pullTableIsLoadingMore properties. For example add the following code to viewWillAppear: if(!self.pullTableView.pullTableIsRefreshing) { self.pullTableView.pullTableIsRefreshing = YES; [self performSelector:@selector(refreshTable) withObject:nil afterDelay:3]; }
