iOS json解析的几种方法 NSJSONSerialization,JSONKit,SBJson ,TouchJson

相关的第三方类库大家可以去github上下载

1.NSJSONSerialization

具体代码如下 ：

- (void)viewDidLoad {

    [super viewDidLoad];

    NSData *data1=[NSData dataWithContentsOfFile:[[NSBundle mainBundle]pathForResource:@"test" ofType:@"json"]];

    //1.系统提供的json解析方法

    NSLog(@"%@",data1);

    __autoreleasing NSError *err;

      NSDictionary *dic=[NSJSONSerialization JSONObjectWithData:data1 options:NSJSONReadingMutableLeaves error:&err];

    NSLog(@"%@",dic[@"user"][@"location"]);

    NSLog(@"%@",dic);

}

2.JSONKit 这是需要导入第三方类库

 [super viewDidLoad];

    NSString *path=[[NSBundle mainBundle]pathForResource:@"sina.json" ofType:nil];

    NSData *data=[NSData dataWithContentsOfFile:path];

    __autoreleasing NSError *err;

    NSDictionary *dic=[data objectFromJSONDataWithParseOptions:JKParseOptionNone error:&err];

    NSLog(@"%@",dic[@"user"][@"location"]);

3.SBJson 同样需要导入第三方类库

- (void)viewDidLoad {

    [super viewDidLoad];

    NSString *path=[[NSBundle mainBundle]pathForResource:@"sina.json" ofType:nil];

    NSData *data=[NSData dataWithContentsOfFile:path];

    SBJsonParser *jsonParser=[[SBJsonParser alloc]init];

    NSMutableDictionary *dic=[jsonParser  objectWithData:data];

    NSLog(@"%@",dic);

}

4.TouchJson 第三方类库

- (void)viewDidLoad {

    [super viewDidLoad];

    NSString *path=[[NSBundle mainBundle]pathForResource:@"sina" ofType:@"json"];

    NSData *data=[NSData dataWithContentsOfFile:path];

    NSDictionary *dic=[[CJSONDeserializer deserializer] deserialize:data error:nil];

    NSLog(@"%@",dic);

}
