iOS EGORefreshTableHeaderView使用方法

廢話不多說，直接上傳代碼說明

1.把EGORefreshTableHeaderView.h和EGORefreshTableHeaderView.m檔案拉入到工程

2.viewcontroller檔案添加引用#import "EGORefreshTableHeaderView.h"和協定<</span>EGORefreshTableHeaderDelegate>

3.定義對象

EGORefreshTableHeaderView *refreshView;

    BOOL reloading;

//注意reloading是必須的

4 實作delegate

#pragma mark - EGORefreshTableHeaderDelegate Methods

//下拉控件重新整理觸發事件

- (void)egoRefreshTableHeaderDidTriggerRefresh:(EGORefreshTableHeaderView*)view{

[self reloadTableViewDataSource];

}

- (BOOL)egoRefreshTableHeaderDataSourceIsLoading:(EGORefreshTableHeaderView*)view{

return reloading; // should return if data source model is reloading

- (NSDate*)egoRefreshTableHeaderDataSourceLastUpdated:(EGORefreshTableHeaderView*)view{

return [NSDate date]; // should return date data source was last changed

#pragma mark - UIScrollViewDelegate Methods

- (void)scrollViewDidScroll:(UIScrollView *)scrollView{

[refreshView egoRefreshScrollViewDidScroll:scrollView];

- (void)scrollViewDidEndDragging:(UIScrollView *)scrollView willDecelerate:(BOOL)decelerate{

[refreshView egoRefreshScrollViewDidEndDragging:scrollView];

注意要實作UIScrollViewDelegate

5 添加load資料的函數和load完資料的函數

#pragma mark Data Source Loading / Reloading Methods

//下拉動作觸發事件調用的函數。在這裡發送資料請求

- (void)reloadTableViewDataSource{

//  should be calling your tableviews data source model to reload

//  put here just for demo

    NSLog(@"dragging!!!");

    timer = [NSTimer scheduledTimerWithTimeInterval:5 target:selfselector:@selector(doneLoadingTableViewData) userInfo:nil repeats:NO];

reloading = YES;

//請求結束函數。在這裡要關閉下拉的視圖.并更新表視圖

- (void)doneLoadingTableViewData{

//  model should call this when its done loading

    NSLog(@"stop loading");

    timer = nil;

reloading = NO;

[refreshView egoRefreshScrollViewDataSourceDidFinishedLoading:self.tableView];

    [listData addObject:[[NSString alloc] initWithFormat:@"%d",[listData count]]];

    [self.tableView reloadData];
