1.拖动TableView时收起键盘

self.tableView.keyboardDismissMode = UIScrollViewKeyboardDismissModeOnDrag;

2.TableView不显示多余的部分表格

self.tableView.tableFooterView = [UIView new];

3.增加下拉刷新操作

 - (void)viewDidLoad {

    UIRefreshControl *rc = [[UIRefreshControl alloc]init];

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

    [rcaddTarget:self action:@selector(refreshTableView)forControlEvents:UIControlEventValueChanged];

    self.refreshControl = rc;

}

-(void)refreshTableView{
  self.refreshControl.attributedTitle=[[NSAttributedString alloc]initWithString:@"加载中....."];
  [self.refreshControl endRefreshing];
  self.refreshControl.attributedTitle = [[NSAttributedString alloc]initWithString:@"下拉刷新"];
  [self.tableView reloadData];
}
