使用多个JSON对象设置单元格的文本 [英] Setting a cell's text with multiple JSON objects

问题描述

这是我目前拥有的代码：

我已经有一个简单的web服务将一些数据传递到表格视图， p>

  [[cell detailTextLabel] setText：[item objectForKey：@Ball 1]]; 
  

正如我所说，这完美地工作，并显示一个球数，例如。 1，取自网络服务。

我想要做的是显示，例如。 1& 3。

查看其他代码我认为可能是：

  [[cell detailTextLabel] setText：[item objectForKey：@Ball 1] item objectForKey：@Ball 2]]; 
  

我完全是Objective-C的新手，我做了几个教程，试图扩展他们一点。

解决方案

使用字符串来解决问题有些困难，因为我不确定这些术语。连接，例如 stringWithFormat ：

  NSString * concated = [NSString stringWithFormat： @％@&％@，[item objectForKey：@Ball 1]，[item objectForKey：@Ball 3]]; 
  

现在将此字符串设置为label：

  [[cell detailTextLabel] setText：concated]; 
  

I've got a simple web service in passing through some data into a table view and it's working fine.

This is the code I currently have:

[[cell detailTextLabel] setText:[item objectForKey:@"Ball 1"]];

As I said, this works perfectly and displays with a ball number, e.g. "1", taken from the web service.

What I want to do is have it display, e.g. "1 & 3".

Looking at some other code I thought it might have been:

[[cell detailTextLabel] setText:[item objectForKey:@"Ball 1"]item objectForKey:@"Ball 2"]];

I'm totally new to Objective-C, and I'm doing a few tutorials and I'm trying to expand on them a bit. It's been a bit difficult to search for answers on some of the stuff because I'm unsure of the terminology.

解决方案

Use string concatenation, e.g stringWithFormat:

NSString *concated = [NSString stringWithFormat:@"%@ & %@", [item objectForKey:@"Ball 1"], [item objectForKey:@"Ball 3"]];

and now set this string to label:

[[cell detailTextLabel] setText:concated];
