It's working fine and posting everything mentioned below on Facebook wall but it throwing following exception and termination application abnormally. I scratched my head a lot but couldn't find anything wrong. Could anyone please tell me what's wrong in my code? FYI I have combined this code from <a href="https://stackoverflow.com/questions/1652049/fbconnect-facebook-stream-publish-with-nsdictionary-problems">link1</a> and <a href="https://stackoverflow.com/questions/2744078/iphone-fbconnect-auto-post-to-user-wall">link2</a>Thanks!</p> <p>Exception:</p> <pre><code>-[NSConcreteMutableData objectForKey:]: unrecognized selector sent to instance 0x34a560 *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[NSConcreteMutableData objectForKey:]: unrecognized selector sent to instance 0x34a560' </code></pre> <p>Login into Facebook code:</p> <pre><code>- (void)login { NSLog(@"Logging into Facebook..."); UniversalAppAppDelegate *delegate = (UniversalAppAppDelegate *) [[UIApplication sharedApplication] delegate]; NSArray* requiredPermissions = [NSArray arrayWithObjects:@"read_stream", @"publish_stream", @"offline_access",nil]; if (![[delegate facebook] isSessionValid]) { [delegate facebook].sessionDelegate = self; [[delegate facebook] authorize:requiredPermissions]; } } </code></pre> <p>Posting on wall:</p> <pre><code>- (void)postCommentToFacebookWall:(NSString*)comment { UniversalAppAppDelegate *delegate = (UniversalAppAppDelegate *) [[UIApplication sharedApplication] delegate]; NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys: kAppId, @"api_key", @"This is test message from my iPhone App",@"message", nil]; [[delegate facebook] requestWithMethodName:@"stream.publish" andParams:params andHttpMethod:@"POST" andDelegate:self]; } </code></pre>

    1. COI've not found any problems with this code. But looks like some NSMutableData object tries to be used instead NSDictionary. i.e. NSData has no "objectForKey:" method. May be this occurs in another place of application.

    2. CO@SVGreg: there is no other place actually! I just call postcomment method with comment argument from app-delegate. I also send comment to my database. If I comment out postcomment to facebook call then everything works fine! It's just problem when I post comment to Facebook!

    3. CODid you implement callbacks methods? You set yourself as delegate in "requestWithMethodName:".

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
