json开源的类库有很多,其中JSONKit库是非常简单易用而且效率又比较高的,重要的JSONKit适用于ios 5.0以下的版本。

使用JSONKit库来解析json文件,只需要下载JSONKit.h 和JSONKit.m添加到工程中;然后加入libz.dylib即可
解析代码举例:
- #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(@"%@",BrandName);
- }
字典arrlist便是解析好的json文件了。
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:@"3" forKey:@"bage" ];
- [aps setObject:@"def.mp3" forKey:@"sound"];
- [jsonDic setObject:aps forKey:@"aps"];
- NSString *strJson = [jsonDic JSONString];
