Question

I have a sample code with a header and an implementation file and the two appDelegate files. I would like to add what the project does to my app. The first two files are a ViewController file, so I just need to drag it in, but the other two are AppDelegate, and I obviously can’t have two app delegates. But in the case of this sample app the app delegate is used as a proper viewcontroller, because in the .m file of the UIViewController file, there is this code:

AppDelegate *appDelegate = [[UIApplication sharedApplication] delegate];

Since the AppDelegate doesn’t implement methods such as applicationWillBecomeActive:, how can I transform the file into a UIViewController file? What do I need to change in the code above to call the controller, instead of the Delegate (my AppDelegate will so remain untouched).

The code is on GitHub

This is what I have done (the code needs the Facebook API to be included). Go on the download tab and download Archive.zip and AppDelegate.zip: https://github.com/Alexmitico45/FacebookRequests/downloads

Basically the controller ContactFBSViewController is linked the a viewcontroller in the storyboard.

Answer 1

I solved the problem. What I had to do is make the viewcontroller a singleton:

+ (FacebookViewController *) sharedManager;

..then use this code to access it:

FacebookManager *manager = [FacebookManager sharedManager];

And after days of trial and error it finally works!!
