iOS 开发 UItableView中滑动删除 cell
主要是就是两个函数
一：- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
相应editingStyle事件处理
在这里主要相应UITableViewCellEditingStyleDelete：
二：(UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath
在这个函数中设置那个cell设置成 什么样的editingStyle删除，插入，无
UITableViewCellEditingStyleDelete
UITableViewCellEditingStyleInsert
UITableViewCellEditingStyleNone
需要注意的问题：在删除对应cell中的内容时，也要删除这个cell，否则运行时显示效果就像没有刷新 一样，多出一个cell。而使用[tableView reloadData];[self loadView];刷新都不管用。必须使用deleteRowsAtIndexPaths:withRowAnimation:函数删除这个cell
[tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];
[tableView reloadData];据说reloadData只是从新加载表项内容，而不会重新设置表内cection中cell的个数。
