• Json
• JSONKit的使用（PS.勿使用SBJson）

 #import "JSONKit.h"

//假设 strJson 是网络上接收到的 json 字符串，
NSString *strJson = @"[{\"Id\: 1,\"BrandName\": \"爱马仕\" },{\"Id\": 2,\"BrandName\": \"安娜苏\"}]"; 
    NSArray *arrlist=[strJson objectFromJSONString];
    NSLog(%d",[arrlist count]);
    for (int i=0; i<[arrlist count]; i++) {
        NSDictionary *item=[arrlist objectAtIndex:i];
        NSString *BrandName=[item objectForKey:BrandName"];
        NSLog(%@ 
   
 

字典arrlist便是解析好的json文件了。

JSONKit库也可以用来生成json文件

代码举例：

NSMutableDictionary *jsonDic = [NSMutableDictionary dictionary];
NSMutableDictionary *alert = [NSMutableDictionary dictionary]
;NSMutableDictionary *aps = [NSMutableDictionary dictionary];
[alert setObject:a msg come!" forKey:body"];
[aps setObject:alert forKey:alert"];
[aps setObject:3bage" ];
[aps setObject:def.mp3sound"];
[jsonDic setObject:aps forKey:aps"];
NSString *strJson = [jsonDic JSONString];
