Question

I have a project that utilizes the Facebook SDK 3.0, which I built it in Xcode 4.3.2. I now must update the project to Xcode 4.5 which also requires me to update the Facebook SDK to 3.1. When I run the project in Xcode 4.5 (without changing anything), it builds and I can connect to Facebook, but of course when I try to run it on my iPhone with OS 6, I get a build failed message. SO, I went through all the tutorials on the FB developer’s site, and changed the code that they highlighted, BUT when I put the new code in, I get all kinds of errors. Xcode does not know what I am talking about anymore. For example, I changed the previous general permissions code to the below “read” permissions code:

- (BOOL)openSessionWithAllowLoginUI:(BOOL)allowLoginUI {
return [FBSession openActiveSessionWithReadPermissions:nil
        allowLoginUI:allowLoginUI
            completionHandler:^(FBSession *session,
                                FBSessionState state,
                                    NSError *error) {
                                         [self sessionStateChanged:session
                                            state:state
                                            error:error];
                                     }];
}

and I get the error, “no known class method for selector…”

Its worth noting that I opened a new Xcode project and rehearsed entering the facebook SDK and all of the code from scratch and it worked perfectly. So my question is, how do I just UPDATE my already existing app to use the new SDK!!?? Help would be GREATLY appreciated!!

Answer 1

I just answered my own question, the SDK was just the old version. Thought I updated it, but apparently not!
