问题描述
我正在做一个项目，我正在从异步连接加载一个带有 JSON 数据的表视图.我正在使用 switch 语句来加载每一行，如下所示:
I am doing a project in which I am loading a table view with JSON data from an asynchronous connection. I am using a switch statement to load each row, like so:
dictionaryData = [responseString JSONValue];
switch (indexPath.row)
{
case 0:
{
NSString *name = [NSString stringWithFormat:@"%@ : %@ %@",@"Name",[dictionaryData valueForKey:@"firstName"],[dictionaryData valueForKey:@"lastName"]];
cell.textLabel.text = name;
break;
}
case 1:
{
NSString *email = [NSString stringWithFormat:@"%@ : %@",@"Email",[dictionaryData valueForKey:@"email"]];
cell.textLabel.text = email; }
break;
有 8 行，我必须编写 8 个 switch case，我认为这使我的方法太长了.谁能告诉我是否有任何替代 switch 语句的方法.
There are 8 rows and i have to write 8 switch cases , which i think makes my method too long. Can anyone tell me that is there any alternative to switch statements.
推荐答案
在某些情况下，object 会是更好的选择.
In some cases an object would be a better alternative.
更新
我在这里详细说明了如何处理这个问题(以过度设计的方式):我可以使用什么替代 switch 语句来更新我的 UITableViewCells?
I detailed how one might approach this (in an overengineered manner) here: What alternatives to a switch statement could I use to update my UITableViewCells?
这篇关于替代目标 C 中的 switch 语句的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持编程学习网！
