How to share text and image on facebook wall (objective C)

I am working on an app which provides user to share the details of their app into facebook . I have UITableview where it contains the list of author name and when u click on book name it goes to another UITableView where it shows the different book of that author in each TableViewCell. I'm able to display the list in 2nd UITableView . I wanted to know how to share the author name , book name and the image (2nd tableview details). I'm showing the code which does that .. So when the user wants to share the details, he will have to tap on the UIButton which is there in every cell of author UITableView.

didselectatindexpath

    NSDictionary *selectedAuthor = nil;

     NSArray *sectionArray=[mainIndexDictionary objectForKey:[allKeysArray objectAtIndex:indexPath.section]];
        selectedAuthor = [sectionArray objectAtIndex:indexPath.row];
        iPath=[[selectedAuthor objectForKey:@"SymptIndexID"] intValue];
        NSLog(@"iPath - %d",iPath);

        authortitleString=[[selectedAuthor objectForKey:@"authorIndexName"]stringByAppendingString:@" cure!"];
    }


    bookArray=[objDB customCellData:(NSInteger)iPath];
    [self.view bringSubviewToFront:authorView];
    [bookTableView scrollRectToVisible:CGRectMake(0.0, 0.0, 320.0,10.0) animated:NO];

    [bookTableView reloadData]

;
