来源：互联网发布：图片上传淘宝变模糊编辑：程序博客网时间：2024/06/05 20:06

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"和协议<</span>EGORefreshTableHeaderDelegate>

3.定义对象

EGORefreshTableHeaderView *refreshView;

BOOL reloading;

注意reloading是必须的

4 实现delegate

#pragma mark - EGORefreshTableHeaderDelegate Methods

//下拉控件刷新触发事件

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

[self reloadTableViewDataSource];

}

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

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

}

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

return [NSDatedate]; // should return date data source waslast changed

}

#pragma mark - UIScrollViewDelegate Methods

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

[refreshViewegoRefreshScrollViewDidScroll:scrollView];

}

- (void)scrollViewDidEndDragging:(UIScrollView *)scrollViewwillDecelerate:(BOOL)decelerate{

[refreshViewegoRefreshScrollViewDidEndDragging:scrollView];

}

注意要实现UIScrollViewDelegate

5添加load数据的函数和load完数据的函数

#pragma mark Data Source Loading / Reloading Methods

//下拉动作触发事件调用的函数。在这里发送数据请求

- (void)reloadTableViewDataSource{

// should be calling your tableviews data sourcemodel to reload

// put here just for demo

NSLog(@"dragging!!!");

timer= [NSTimerscheduledTimerWithTimeInterval:5target:self selector:@selector(doneLoadingTableViewData)userInfo:nil repeats:NO];

reloading = YES;

}

//请求结束函数。在这里要关闭下拉的视图.并更新表视图

- (void)doneLoadingTableViewData{

// model should call this when its doneloading

NSLog(@"stop loading");

timer = nil;

reloading = NO;

[refreshViewegoRefreshScrollViewDataSourceDidFinishedLoading:self.tableView];

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

[self.tableView reloadData];

}
