IOS tableview下拉刷新上拉加载分页

http://code4app.com/ios/快速集成下拉上拉刷新/52326ce26803fabc46000000

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];

}
