- (void)dialogDidComplete:(FBDialog*)dialog is called even when user selected "Skip" about facebook-ios-sdk

The dialogDidComplete actually means the user click a button within the webView dialog and get the dialog go through. No matter the user click the Cancel or OK button. To see whether the dialog did succeed or not, if it is LoginDialog, the dialog fbDidLogin and fbDidNotLogin will corresponding to successfully log in or user cancel the login. For other dialog you would need to parse the url returned from the webView dialog by implementing the delegate method defined in FBDialog.h

• (void)dialogCompleteWithUrl:(NSURL *)url;.

  For example, stream.publish, if succeed, the returned url will have a post_id appended to the url. We will have a document for all dialogs about what would be a succeed url. Check back with our facebook developer website.

Hope this explains. Thanks!

It seems that it would be a pretty common requirement to need to know whether the dialog was closed because the user canceled or because the dialog completed the action it was intended for.

In the current API if the user clicks the x in the top right of a dialog the FBDialog method - (void)dialogDidCancel:(NSURL *)url gets called which subsequently calls the delegate method - (void) dialogDidNotComplete.

So it seems that there is some intention of letting the developer know that an action was cancelled. Perhaps it was just an oversite that the skip button doesn't similarly trigger this effect.

Regarding parsing the url in dialogCompleteWithUrl, the url returned by the publish dialog when the skip button is pressed seems to be "fbconnect://success" which doesn't do a very good job of indicating that the user chose to cancel an action.

Either way this API could stand to be improved quite a bit.
