长话短说。我只需要访问JSON文件中的父级。 How to parse multiple json in objective-c?）我需要访问作者＆gt;来自此JSON的NAME 。（*删除链接）

代码是：

NSURL *blogURL = [NSURL URLWithString:@"*removed link"];

    NSData *jsonData = [NSData dataWithContentsOfURL:blogURL];

    NSError *error = nil;

    NSDictionary *dataDictionary = [NSJSONSerialization JSONObjectWithData:jsonData options:0 error:&error];
//    NSLog(@"%@",dataDictionary);

    self.blogPosts = [NSMutableArray array];

    NSArray *blogPostsArray = [dataDictionary objectForKey:@"posts"];

    for (NSDictionary *bpDictionary in blogPostsArray) {
        BlogPost *blogPost = [BlogPost blogPostWithTitle:[bpDictionary objectForKey:@"title"]];
        blogPost.author = [bpDictionary objectForKey:@"author"];
        blogPost.thumbnail = [bpDictionary objectForKey:@"thumbnail"];
        blogPost.date = [bpDictionary objectForKey:@"date"];
        blogPost.url = [NSURL URLWithString:[bpDictionary objectForKey:@"url"]];
        [self.blogPosts addObject:blogPost];
    }

如何让它访问该值？

您应该可以使用点符号

JSON

{
    "author": {
                "name" : "mckeejm"
              }
}

目标C：

blogPost.author = [bpDictionary valueForKeyPath:@"author.name"];
