tableview常用方法

    // Do any additional setup after loading the view.
    
    self.myTableView.delegate= self;
    self.myTableView.dataSource = self;
    self.myTableView.tableFooterView =[[UIView alloc] initWithFrame:CGRectZero];//删除多余的cell分割线
    
    self.myTableView.backgroundColor = BGCOLOR;

    //    self.myTableView.separatorStyle= UITableViewCellSeparatorStyleNone;//去除分割线
    
    //这个去除分割线方法必须写在注册cell的后面。
