UItableView中滑动删除 cell

2011-11-30 10:42 302 查看

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。
