下面来介绍一下

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;

}
