Question

I have figured out how to add a post to my users feed, but currently it requires using an image URL:

// The action links to be shown with the post in the feed
NSArray* actionLinks = [NSArray arrayWithObjects:[NSDictionary dictionaryWithObjectsAndKeys:
                                                  self.title,@"name",self.url,@"link", nil], nil];
NSString *actionLinksStr = [jsonWriter stringWithObject:actionLinks];

// Dialog parameters
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                               self.title, @"name",
                               @"Created using My App.", @"caption",
                               @"Check out the thing I just uploaded!", @"description",
                               self.url, @"link",
                               @"http://www.facebookmobileweb.com/hackbook/img/facebook_icon_large.png", @"picture",
                               actionLinksStr, @"actions",
                               nil];

[facebook dialog:@"feed" andParams:params andDelegate:self];

I would like to upload a UIImage instead. I have seen some people talking about using the graph api for this. How would I do this and still be able to use a caption, title and message?

Answer 1

Replace your four lines of code by these two :

NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:YourUIImage, @"source",@"caption description",@"message",  nil];

[facebook requestWithGraphPath:[NSString stringWithFormat:@"/me/photos?access_token=%@", facebook.accessToken] andParams:params andHttpMethod:@"POST" andDelegate:self];

and ‘YourUIImage’ by your UIImage.
Hope I answered your question!
