嗨，我是 ios 的新手，我正在将我的应用程序与服务集成，在收到服务的响应后，我存储了上面的字典值，如下面的代码，但它显示异常

请帮助我如何在一个 NSstring 中存储以上 kay 值

我的代码:-

 NSString *SourceAdrees = [NSString stringWithFormat:@"%@\n %@ %@ %@" ,[[[[[dicCurrentIndex valueForKeyPath:@"source"]valueForKey:@"Address1"]valueForKey:@"City"]valueForKey:@"State"]valueForKey:@"Zip"]];

   NSLog(@"SourceAdrees is %@",SourceAdrees);

如果我明白你想做什么，代码应该是这样的:

NSDictionary *sourceDict = dicCurrentIndex[@"source"];
NSString *sourceAddress = [NSString stringWithFormat:@"%@\n %@ %@ %@", 
  sourceDict[@"Address1"], 
  sourceDict[@"City"], 
  sourceDict[@"State"], 
  sourceDict[@"Zip"] ];

(变量名要以小写字母开头，单词是“address”，不是“SourceAdrees”)
