    下面来介绍一下

    BOOL refreshing

    简单贴出 自己写的refresh的代码DEMO

    #import "RefreshTableViewController.h"

    @interface RefreshTableViewController ()

    @property (nonatomic,strong)NSMutableArray *arrM;

    @end

    @implementation RefreshTableViewController

    - (void)viewDidLoad {

        [super viewDidLoad];

        

        

      

        [self initRefreshView];

      

        self.arrM = [NSMutableArray arrayWithObjects:@"haha", nil];

        // Uncomment the following line to preserve selection between presentations.

        // self.clearsSelectionOnViewWillAppear = NO;

        

        // Uncomment the following line to display an Edit button in the navigation bar for this view controller.

        // self.navigationItem.rightBarButtonItem = self.editButtonItem;

    }

    -(void)initRefreshView

    {

        self.refreshControl = [[UIRefreshControl alloc]initWithFrame:CGRectMake(0, 40, self.view.frame.size.width, 40)];

        self.refreshControl.attributedTitle = [[NSAttributedString alloc]initWithString:@"refresh..." attributes:@{NSFontAttributeName:[UIFont systemFontOfSize:20],NSForegroundColorAttributeName:[UIColor redColor]}];

        

        [self.tableView.tableHeaderView addSubview:self.refreshControl];

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

        

        

    }

    -(void)refresh

    {

        [self performSelector:@selector(addData) withObject:nil afterDelay:0.1];

    }

    -(void)addData

    {

        [self.arrM insertObject:@"hahahahah" atIndex:0];

        [self.tableView reloadData];

        [self.refreshControl endRefreshing];

    }

    - (void)didReceiveMemoryWarning {

        [super didReceiveMemoryWarning];

        // Dispose of any resources that can be recreated.

    }

    #pragma mark - Table view data source

    - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {

        return 1;

    }

    - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {

        return self.arrM.count;

    }

    - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

        

        static NSString *id = @"cell";

        UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:id

                                                                forIndexPath:indexPath];

        

        if (!cell) {

            cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:id];

        }

        cell.textLabel.text =self.arrM[indexPath.row];

       

        

        return cell;

    }
