I wanted to add on my personal experience on using BMSocialShare created by vinzenzweber here, and my reputation only allows me to answer. It saved me a lot of time and from the trouble of reading Facebook's documentation, for something as simple as sharing an image for my photo app.

Just a couple of pointers on the documentation of it which might not be immediately obvious for someone using the library for the first time.

1. When inserting the snippet into your Info.plist containing the Facebook app id, you need to affix 'fb' in front of the number app id.

2. Besides adding the BMSocialShare.framework into the Xcode Project, you need to manually drag the BMSocialShare.bundle and the FBDialog.bundle in the resources folder of the BMSocialShare.framework, into the Copy Bundle Resources section under Build Phrases of your application's target

Before sharing you will always have to get the Facebook credentials first by either opening the Facebook App (which is called SSO / Single Sign On) or, in case the Facebook App is not installed, by opening the WebView or Safari. Posting stuff to Facebook can be pretty tricky therefore I wrote a simple lib, called BMSocialShare. It is also supporting "single click sharing". You can do things like uploading photos to Facebook easily:

BMFacebookPost *post = [[BMFacebookPost alloc] initWithImage:[UIImage imageNamed:@"image.png"]];
[[BMSocialShare sharedInstance] facebookPublish:post];

or also create a normal post:

BMFacebookPost *post = [[BMFacebookPost alloc] 
                        initWithTitle:@"Simple sharing via Facebook, Email and Twitter for iOS!" 
                        descriptionText:@"Posting to Facebook, Twitter and Email made dead simple on iOS. Simply include BMSocialShare as a framework and you are ready to go." 
                        andHref:@"https://github.com/blockhaus/BMSocialShare"];    

[post setImageUrl:@"http://www.blockhausmedien.at/images/logo-new.gif" 
         withHref:@"http://www.blockhaus-media.com"];

[[BMSocialShare sharedInstance] facebookPublish:post];
