刷新没用用插件,加载使用的MJ老师的插件。

- (void)viewDidLoad

{

    [super viewDidLoad];

    //获取数据

    [self firstLoadRefresData];

    //下拉刷新

    self.refreshControl = [[UIRefreshControl alloc]init];

    self.refreshControl.tintColor=[UIColor blueColor];

    [self.refreshControl addTarget:self action:@selector(controlEventValueChanged:) forControlEvents:UIControlEventValueChanged];

    // 集成上拉加载控件

    [self setupRefresh];

 

}

/**

 *  集成刷新控件

 */

 

- (void)setupRefresh

{

    [self.tableView addFooterWithTarget:self action:@selector(footerRereshing)];

    self.tableView.footerPullToRefreshText = @"上拉可以加载更多数据了";

    self.tableView.footerReleaseToRefreshText = @"松开马上加载更多数据了";

    self.tableView.footerRefreshingText = @"MJ哥正在帮你加载中,不客气";

}

- (void)footerRereshing

{

    // 1.添加假数据

    if ([self.docs hasNextPage]) {

        [self setData:[[self.docs page]intValue]+1];

    }

    // 2.2秒后刷新表格UI

    dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(2.0 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{

        // 刷新表格

        [self.tableView reloadData];

        // (最好在刷新表格后调用)调用endRefreshing可以结束刷新状态

        [self.tableView footerEndRefreshing];

    });

}

 

 

-(void)controlEventValueChanged:(id)sender{

    if (self.refreshControl.refreshing) {

        self.refreshControl.attributedTitle=[[NSAttributedString alloc]initWithString:@"刷新中"];

        [self performSelector:@selector(refreshData) withObject:nil afterDelay:0.5];

    }

}

-(void)refreshData{

    //请求数据

    [self firstLoadRefresData];

    //刷新表格

    [self.tableView reloadData];

    //完成刷新

    [self.refreshControl endRefreshing];

    self.refreshControl.attributedTitle=[[NSAttributedString alloc]initWithString:@"下拉刷新"];

}

使用AFNetworking库,取得数据。

-(void)setData:(int) p {

    NSString *string = [NSString stringWithFormat:@"%@p=%d&ps=10", BaseURLString,p];

    NSURL *url = [NSURL URLWithString:string];

    NSURLRequest *request = [NSURLRequest requestWithURL:url];

    AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request];

    operation.responseSerializer = [AFJSONResponseSerializer serializer];

    [operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) {

        self.docs=(NSMutableDictionary *)responseObject;

        NSMutableArray *doclist=[[NSMutableArray alloc]initWithCapacity:10];

        [doclist addObjectsFromArray:self.infos];

        [doclist addObjectsFromArray:[self.docs info]];

        self.infos=doclist;

        [self.tableView reloadData];

    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {

        UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Error Retrieving Weather"

                                                            message:[error localizedDescription]

                                                           delegate:nil

                                                  cancelButtonTitle:@"Ok"

                                                  otherButtonTitles:nil];

        [alertView show];

    }];

    [operation start];

}
