我是iPhone新手。我从服务器接收一些数据然后如何在JSON中解析数据。在这里，我想要解析JSON后所有人的名字。以下是我从服务器接收数据的可能性如何？

您需要为Objective-C使用JSON解析库。我建议JSON Framework。 （现在它被称为SBJson）它被广泛使用。我们一直在几个项目中使用它，但没有任何问题。
答案 1 :(得分：0)
-(void)getData:(NSData*)response{
// You have to include the SBJSON or else you can also use the NSJSONSerialization
//NSDictionary *jsonData = [NSJSONSerialization JSONObjectWithData:response options:kNilOptions error:&erro];
SBJSON *parse = [[SBJSON alloc]init];
NSString *jsonString = [[NSString alloc] initWithData:response
encoding:NSUTF8StringEncoding];
NSDictionary *jsonData = [parse objectWithString:jsonString error:&erro];
NSArray *alldata = [jsonData objectForKey:@"data"];
if(![alldata isKindOfClass:[NSNull class]] && [alldata count] > 0)
{
for(int i = 0; i < [alldata count]; i++)
{
NSDictionary *getData = [allEvents objectAtIndex:i];
NSString *nameString = [NSString stringWithFormat:@"%@",[getData objectForKey:@"name"]];
NSString *idString = [NSString stringWithFormat:@"%@",[getData objectForKey:@"id"]];
}
}
}

我是JSONKit的粉丝。它实现起来要小得多（只有.h和.m文件）并且非常快速和高效。 SBJson也很好，但是大多数人不需要很多开销。 （流，写作等）。
NSDictionary *myData = [jsonString objectFromJSONString];
NSString *name = [myData objectForKey:@"data"] objectForKey:@"name"];
NSArray *names = [myData objectForKey:@"data"]; // save all names into an array

iOS 5版本中包含JSON的API函数。 检查API文档中的NSJSONSerialization。
e.g：
NSDictionary *dict = [NSJSONSerialization JSONObjectWithData: data options: kNilOptions error: error];

首先你应该添加Json框架。获取字典变量来加载json的响应。因为字典格式的数据。然后在一个数组中找到一个数组并加载该字典。然后将值存储到对象中，最后得到值
