Thanks you so much for this post.
However I tried to use your "FacebookAgent" code, but I am getting crash. May be I am not using it properly.

Following is my usage:

//Creating facebook agent instance.
facebookAgent = [[FacebookAgent alloc] initWithApiKey:@"<MY API KEY>" ApiSecret:@"<MY SECRET KEY>" ApiProxy:nil];

//Uploading image
UIImage* img = [UIImage imageNamed:@"1.png"];
[facebookAgent uploadPhotoAsData:(NSData*)img withCaption:@"hello" toAlbum:@"hello"];

For the above code I am getting following console log

Any help is really appreciated.
