如何在控制台上打印json输出

问题描述

| 我正在使用Facebook graph API，并以json格式获取其结果。我能够打印一些结果，但在其他结果中却感到困惑。

  application =         {
        id = 142759389130183;
        name = iphonemini;
    };
    caption = \"widevision.co.in\";
    \"created_time\" = \"2011-06-14T07:56:38+0000\";
    from =         {
        id = 100001507678574;
        name = \"Widevision Dev\";
    };
    icon = \"http://www.facebook.com/images/icons/hidden.gif\";
    id = \"100001507678574_173203589406562\";
    link = \"http://widevision.co.in/\";
    message = \"Good Afternoon\";
    name = \"Check It out\";
    type = link;
    \"updated_time\" = \"2011-06-14T07:56:38+0000\";
},

我可以通过此代码打印此图标id链接

FbGraphResponse *fb_graph_response = [fbGraph doGraphGet:@\"me/feed\" withGetVars:nil];


    NSLog(@\"method called\");
    //parse our json
    SBJSON *parser = [[SBJSON alloc] init];
    NSDictionary *facebook_response = [parser    objectWithString:fb_graph_response.htmlResponse error:nil];    

    [parser release];

    //NSString *feed;
    //  NSString *feed2;
    NSMutableArray *feed =(NSMutableArray *) [facebook_response objectForKey:@\"data\"];

    //  NSMutableArray *feed1=(NSMutableArray *) [feed valueForKey:@\"type\"];


    NSLog(@\"Feed %@\",feed );

    NSLog(@\"Message is %@ \",[feed valueForKey:@\"icon\"]);

    NSLog(@\"Name is %@\",[feed valueForKey:@\"name\"]);

..也得到这个

from ={
    id= ;
    name = \"\";
    }


NSMutableArray *streams = (NSMutableArray *)[feed valueForKey:@\"from\"];



    // loop over all the stream objects and print their titles
        int index;
        NSMutableDictionary *stream;

        for (index = 0; index < [feed count];index++) {
            stream = (NSMutableDictionary *)[streams objectAtIndex:index];



            NSLog(@\"Message is %@:\",[stream valueForKey:@\"name\"]);

        }

但是我该如何解析

comments  = { }....

{
        application =         {
            id = 136664723060869;
            name = Iphoneapp;
        };
        caption = \"bit.ly\";
        comments =         {
            count = 2;
            data =             (
                                {
                    \"created_time\" = \"2011-06-14T07:39:45+0000\";
                    from =                     {
                        id = 100001507678574;
                        name = \"Widevision Dev\";
                    };
                    id = \"100001507678574_164163733643881_1822049\";
                    likes = 1;
                    message = hi;
                },{
                    \"created_time\" = \"2011-06-14T08:17:31+0000\";
                    from =                     {
                        id = 100001507678574;
                        name = \"Widevision Dev\";
                    };
                    id = \"100001507678574_164163733643881_1822143\";
                    message = hmmm;
                }
            );
        };

请帮忙     

解决方法

        好吧，我在这里看到一个清晰的json对象。我以SBJSON为例，其中所有JSON都解析为NSDictionary对象，其中“ 5”是键。用于评论的对象又构成了一个带有键的字典。

count,data

。到达“ 7”后，您将拥有一个完整数据数组，因此该数组包含多个字典。在数据数组中获取每个字典应该可以解决您的问题。祝你好运。
