How to Comment or Like a Photo in Facebook Through Fbconnect or Graph API in iPhone Sdk

How to comment or like a photo in facebook through FBconnect or Graph API in iPhone SDK?

To "Like" a Photo (or everthing else with an ID) just post your Acces-Token to the Graph API, e.g. your photo has the ID 123456789. So you have to post your Access-Token to https://graph.facebook.com/123456789/likes.

To comment on a Photo do the same, but post a message (as a parameter) to the Graph API, e.g. https://graph.facebook.com/123456789/comments.

In Code call the following method (defined in Facebook.h) with your path and no parameters for "Like" and a message as a parameter for "Comment":

-(void) requestWithGraphPath:(NSString *)graphPath 
                   andParams:(NSMutableDictionary *)params 
               andHttpMethod:(NSString *)httpMethod 
                 andDelegate:(id <FBRequestDelegate>)delegate

Note, that the httpMethod should be "POST" and the Facebook iOS SDK automaticaly adds your Access-Token.

For more information read the "Publishing" part on: http://developers.facebook.com/docs/reference/api

Edit:
Like deanWombourne wrote in the comments: Just post an NSMutableDictionary like this

[NSMutableDictionary dictionaryWithObjectsAndKeys:@"This is my comment", @"message", nil];

for the comments or an empty NSMutableDictionary like:

[NSMutableDictionary dictionary]

if you want to like a post.

The response from the Facebook servers should be result = true.

How to get photos of a facebook album in iPhone SDK?

So /me/albums returns an array of Album objects, each of which has an id.

If an album had an id of 99394368305, you can go to

https://graph.facebook.com/99394368305/photos

to get an array of photo objects.

Each of these will have the picture and source properties to get the image data from facebook.

They will all have an images array as well if you want pre-scaled images instead of just the originals.

Post to user's Facebook wall with iPhone using latest FBConnect SDK

Have you looked at DemoApp under the sample directory in facebook-ios-sdk? There's a publishStream method that might help.

Or, you can use

- (void)requestWithGraphPath:(NSString *)graphPath
                   andParams:(NSMutableDictionary *)params
               andHttpMethod:(NSString *)httpMethod
                 andDelegate:(id <FBRequestDelegate>)delegate;

like this:

[_facebook requestWithGraphPath:@"[user_id]/feed" 
                      andParams:[NSMutableDictionary dictionaryWithObject:@"test wall post" forKey:@"message"]
                  andHttpMethod:@"POST"
                    andDelegate:self];

to post a comment to [user_id]'s wall.
