Question

当我滑动并点击桌面视图上的删除按钮时，我想要一个警报确认。基本上我想在发送数据之前用“ok”和“cancel”按钮显示一个警告弹出窗口：

[[ConnectionSingleton getInstance] sendData:[NSString stringWithFormat:@"modifOrderFoodState::%@::%@::%@", [cellOrder objectForKey:@"orderFoodRelId"], state, [ConnectionSingleton getInstance].restaurantId] ];

如果客户端点击取消按钮，则支持发送数据功能。

这是我的代码：

- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {

NSMutableDictionary *cellOrder = [orders objectAtIndex:indexPath.row];
NSString *state = @"4";

if (editingStyle == UITableViewCellEditingStyleDelete) {


    [[ConnectionSingleton getInstance] sendData:[NSString stringWithFormat:@"modifOrderFoodState::%@::%@::%@",
                                                 [cellOrder objectForKey:@"orderFoodRelId"],
                                                 state,
                                                 [ConnectionSingleton getInstance].restaurantId] ];
  }    
}

将此类设为UIAlertViewDelegate。删除样式时创建UIAlertView。将发送数据代码移动到alertView：clickedButtonAtIndex：方法，并在用户单击“确定”时运行它。
