iOS EGORefreshTableHeaderView使用方法
废话不多说，直接上传代码说明
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 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 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;
}
//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 done loading
NSLog(@"stop loading");
timer = nil;
reloading = NO;
[refreshView egoRefreshScrollViewDataSourceDidFinishedLoading:self.tableView];
[listData addObject:[[NSString alloc] initWithFormat:@"%d",[listData count]]];
[self.tableView reloadData];
}
