//滑动删除

- (UITableViewCellEditingStyle)tableView:(UITableView *)tableView

editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath      //当在Cell上滑动时会调用此函数

{

if(temp == 1 || temp == 2)

return  UITableViewCellEditingStyleDelete;  //返回此值时,Cell会做出响应显示Delete按键,点击Delete后会调用下面的函数,别给传递UITableViewCellEditingStyleDelete参数

else

return  UITableViewCellEditingStyleNone;   //返回此值时,Cell上不会出现Delete按键,即Cell不做任何响应

}

- (void) tableView:(UITableView *)tableView

commitEditingStyle:(UITableViewCellEditingStyle)editingStyle

forRowAtIndexPath:(NSIndexPath *)indexPath 　　//对选中的Cell根据editingStyle进行操作

{

if (editingStyle == UITableViewCellEditingStyleDelete)

{

if (temp == 1)　　//将单元格从数据库1中删除
