Changing AppDelegate file of example I want to use in my app - ios

Question

Hi all I'm new in creating app for iOS , so sorry if the question stupid a little .
I'm trying to build app where log in to Facebook and getting friend list is only a part, so I want to use the example providing from Facebook to developers , but it have appDelegate file with some methods like this:
#import "FPAppDelegate.h"
#import "FPViewController.h"
#implementation FPAppDelegate
#synthesize window = _window;
#synthesize rootViewController = _rootViewController;
- (BOOL)application:(UIApplication *)application
.......
return [FBSession.activeSession handleOpenURL:url];
}
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
[FBFriendPickerViewController class];
........
return YES;
}
- (void)applicationWillTerminate:(UIApplication *)application {
[FBSession.activeSession close];
}
And it have xib file for FPViewController with h and m files, so what the better way to use this example in my app, I understand that I can't use two appDelegate files, and I trying to change FPAppDelegate that is UIResponder to UIViewController class to push it from some place in my app like this:
- (IBAction)loginFacebook:(id)sender
{
NSLog(#"Facebook");
delegateViewController *appDelegate = [[delegateViewController alloc] initWithNibName:nil bundle:NULL];
[self.navigationController pushViewController: appDelegate animated:YES];
}
where delegateViewController is FPAppDelegate of example I changing to:
#import "delegateViewController.h"
#import "AppDelegate.h"
#import "FPViewController.h"
#interface delegateViewController ()
#end
#implementation delegateViewController
#synthesize window2=_window2;
#synthesize rootViewController2=_rootViewController2;
- (BOOL)application:(UIApplication *)application
......
return [FBSession.activeSession handleOpenURL:url];
}
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
[FBFriendPickerViewController class];
......
self.window2 = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.window2.rootViewController = navigationController;
[self.window2 makeKeyAndVisible];
return YES;
}
- (void)applicationWillTerminate:(UIApplication *)application {
........
[FBSession.activeSession close];
}
but it's not working, so, if I need to change also xib file? Or to change appDelegate file of my project? Or existing another way to use this example in my app? I would like you to explain this to me.

You should start by working through the Apple tutorials so you can understand the UIKit framework to start developing an iOS app.
