And I want to show every data in the organized structure in the console. Can anyone help me with this?

Answer 1

it's unclear what you exactly asking but I try to answer.

First of all you need to parse this response in the method - (void)request:(FBRequest *)request didLoad:(id)result of Facebook iOS SDK

result can be a string, a NSArray if you have multiple results and NSDictionary

In you console output we can see NSDictionary with included arrays and dictionaries in it. I have little tutorial about it but it's on russian only and site is down today :( so i just copy one example from my article.

Let say we want to know what facebook user Likes

- (IBAction)getUserInfo:(id)sender {
  [_facebook requestWithGraphPath:@"me/likes" andDelegate:self];
}

if we try this Graph API response in browser or output to console we can see what this request returns. It returns dictionary with one and only key - "data" and corresponded array to this key. This array contents dictionary objects again with keys -
«name»,"category","id","created_time". Dont forget request «user_likes» permission before. So we have parsing method like that:

- (void)request:(FBRequest *)request didLoad:(id)result {
    if ([result isKindOfClass:[NSArray class]]) {
        result = [result objectAtIndex:0];
    }
    if ([result objectForKey:@"owner"]) {
        [self.label setText:@"Photo upload Success"];
    } else if ([result objectForKey:@"data"]){
        NSArray *likes = [result objectForKey:@"data"];
        NSString *text=@"You don't like Steve";
        for (NSDictionary* mylike in likes) {
            NSString *mylikeName = [mylike objectForKey:@"name"];
            if ([mylikeName isEqualToString:@"Steve Jobs"]) {
                text=@"You like Steve";
                break;
            }
        }
        [self.label setText:text];
    }
};

You can parse you result same way and fill your object's variables and then use it to display information in TableView for example. good luck!
