iOS中EGORefreshTableHeaderView怎么用

小編給大家分享一下iOS中EGORefreshTableHeaderView怎么用，相信大部分人都還不怎么了解，因此分享這篇文章給大家參考一下，希望大家閱讀完這篇文章后大有收獲，下面讓我們一起去了解一下吧！

1.把EGORefreshTableHeaderView.h和EGORefreshTableHeaderView.m文件拉入到工程

2.viewcontroller文件添加引用#import "EGORefreshTableHeaderView.h"和協(xié)議<</span>EGORefreshTableHeaderDelegate>

3.定義對(duì)象

EGORefreshTableHeaderView *refreshView;

    BOOL reloading;

//注意reloading是必須的

4 實(shí)現(xiàn)delegate

#pragma mark - EGORefreshTableHeaderDelegate Methods

//下拉控件刷新觸發(fā)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(shí)現(xiàn)UIScrollViewDelegate

5 添加load數(shù)據(jù)的函數(shù)和load完數(shù)據(jù)的函數(shù)

#pragma mark Data Source Loading / Reloading Methods

//下拉動(dòng)作觸發(fā)事件調(diào)用的函數(shù)。在這里發(fā)送數(shù)據(jù)請(qǐng)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(qǐng)求結(jié)束函數(shù)。在這里要關(guān)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];

}
