ios下拉刷新上拉加载EGORefresh简单实现

前提下载 EGORefreshTableHeaderView.h  EGORefreshTableHeaderView.m
EGORefreshTableFootView.h     EGORefreshTableFootView.m  以及8张图片
并拖入工程



在.pch文件里导入

#import "EGORefreshTableHeaderView.h"

#import "EGORefreshTableFootView.h"
在.h文件里

UIScrollViewDelegate,EGORefreshTableHeaderDelegate,EGORefreshTableFootDelegate>

{

    EGORefreshTableHeaderView *_refreshHeaderView;

EGORefreshTableFootView* _footerView;

//  Reloading var should really be your tableviews datasource

//  Putting it here for demo purposes

BOOL _reloading;

    BOOL _headerRefresh;

}

@property (nonatomic ,assign) NSInteger pageNumber;

@property(retain,nonatomic)UITableView *tableView;

@property (nonatomic ,retain) NSMutableArray * newdataArray;//新闻数据数组


在.m文件里

viewdidload里

当前页

_pageNumber = 1;
 

创建刷新视图

_refreshHeaderView = [[EGORefreshTableHeaderView alloc] init];

_refreshHeaderView.frame = CGRectMake(0.0f, 0.0f - self.tableView.bounds.size.height, self.tableView.bounds.size.width, self.tableView.bounds.size.height);

_refreshHeaderView.delegate = self;

[self.tableView addSubview:_refreshHeaderView];

_footerView = [[EGORefreshTableFootView alloc] init];

_footerView.frame = CGRectMake(0,0, self.tableView.bounds.size.width, 0);

_footerView.delegate = self;

self.tableView.tableFooterView = _footerView;

[_refreshHeaderView refreshLastUpdatedDate];

然后在外面导入 

#pragma mark - 下拉刷新

- (void)finishRefresh{

    //LOG_METHOD;

    if (NO == _headerRefresh) {

        //上拉加载

        [self.tableView reloadData];

        [_footerView egoRefreshScrollViewDataSourceDidFinishedLoading:self.tableView];

    }

    else{

        //下拉刷新 默认刷新

        [self.tableView reloadData];

        [_refreshHeaderView egoRefreshScrollViewDataSourceDidFinishedLoading:self.tableView];

    }

    _reloading = NO;

}

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

    //LOG_METHOD;

    _reloading = YES;

    _pageNumber = 1;

    [self loadnewdata];

    [NSTimer scheduledTimerWithTimeInterval:0 target:self selector:@selector(finishRefresh) userInfo:nil repeats:NO];

}

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

    //   NSLog(@"isLoading");

    //LOG_METHOD;

    return _reloading;

}

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

    //LOG_METHOD;

    return [NSDate date];

}

#pragma mark - Footer Refresh delegate methods

- (void)egoRefreshTableFootDidTriggerRefresh:(EGORefreshTableFootView*)view{

    //LOG_METHOD;

    _reloading = YES;

    _pageNumber = _pageNumber+1;

    int second = [self.newdataArray count];

    int index = second/ 10;

    second = second - index*10;

    if (second <= 0) {

        [self loadnewdata];

    }

    [NSTimer scheduledTimerWithTimeInterval:0 target:self selector:@selector(finishRefresh) userInfo:nil repeats:NO];

}

- (BOOL)egoRefreshTableFootDataSourceIsLoading:(EGORefreshTableFootView*)view{

    //LOG_METHOD;

    return _reloading;

}

- (NSDate*)egoRefreshTableFootDataSourceLastUpdated:(EGORefreshTableFootView*)view{

    //LOG_METHOD;

    return  [NSData data];

}

#pragma mark - scroll delegate methods

//scrollView delegate

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

    //LOG_METHOD;

    CGPoint offset1 = scrollView.contentOffset;

    CGRect bounds1 = scrollView.bounds;

    UIEdgeInsets inset1 = scrollView.contentInset;

    float y1 = offset1.y + bounds1.size.height - inset1.bottom;

    if (y1 > self.tableView.frame.size.height) { //判断是下拉刷新 还是上拉加载

        _headerRefresh = NO;    //上拉加载

        [_footerView egoRefreshScrollViewDidScroll:scrollView];

    }

    else if (y1 < self.tableView.frame.size.height) {

        _headerRefresh = YES;   //下拉刷新

        [_refreshHeaderView egoRefreshScrollViewDidScroll:scrollView];

    }

    else if (y1 == self.tableView.frame.size.height) {

        //        DLog(@"%@", flagShuaxin ? @"上拉刷新" : @"下拉刷新");

    }

}

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

    //LOG_METHOD;

    if (YES == _headerRefresh ) { //下拉刷新

        [_refreshHeaderView egoRefreshScrollViewDidEndDragging:scrollView];

    }

    else{ //上拉加载更多

        [_footerView egoRefreshScrollViewDidEndDragging:scrollView];

    }

}

请求数据

-(void)loadnewdata{

    NSString *str=[hostname stringByAppendingString:HttpForNewsdataShow];

    NSString *astr=[NSString stringWithFormat:@"?ChannelID=%@&PageNums=10&CurrentPage=%d",self.lanmuID,_pageNumber];

    NSString *allstrurl=[str stringByAppendingString:astr];

    NSLog(@"allstrurl   %@",allstrurl);

    ASIFormDataRequest *requestlogin = [ASIFormDataRequest requestWithURL:[NSURL URLWithString:allstrurl]];

    requestlogin.tag = 300;

    requestlogin.delegate = self;

    [requestlogin startAsynchronous];

}

请求成功后

 if (request.tag == 300)

   {

       NSString* jsonStr = [request responseString];

       NSMutableDictionary * dic1;

       dic1 = [jsonStr JSONValue];

       NSMutableArray * array = [dic1 objectForKey:@"result"];

       if (_pageNumber == 1) {

           [self.newdataArray removeAllObjects];

           self.newdataArray = [NSMutableArray arrayWithArray:array] ;

           self.tableView.tableFooterView.hidden = NO;

       }

       else

       {

           [self.newdataArray addObjectsFromArray:array];

       }

       if ([array count]< 10) {

           self.tableView.tableFooterView.hidden = YES;

       }

       [self.tableView  reloadData];

   }

运行大功告成！！！！
