Creating a first launch viewcontroller - ios

Question

I'm trying to create a "initial setup page" that is shown if the app is launched for the first time on the device.
I made it like this:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
if ([[NSUserDefaults standardUserDefaults] boolForKey:#"HasLaunchedOnce"])
{
NSLog(#"not first launch");
self.viewController = [[ViewController alloc] initWithNibName:#"ViewController" bundle:nil];
self.window.rootViewController = self.viewController;
[self.window makeKeyAndVisible];
return YES;
}
else
{
[[NSUserDefaults standardUserDefaults] setBool:YES forKey:#"HasLaunchedOnce"];
[[NSUserDefaults standardUserDefaults] synchronize];
NSLog(#"first launch");
}
}
Now I want to create a view controller and push to this view controller if it's the first time the app is launched.
What do I need to do?

Answer 1

Create a new ViewController. Import the header in appDelegate.h file also create a instance variable of that class with name initialViewController.
Change your else condition like:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
if ([[NSUserDefaults standardUserDefaults] boolForKey:#"HasLaunchedOnce"])
{
NSLog(#"not first launch");
self.viewController = [[ViewController alloc] initWithNibName:#"ViewController" bundle:nil];
self.window.rootViewController = self.viewController;
}
else
{
[[NSUserDefaults standardUserDefaults] setBool:YES forKey:#"HasLaunchedOnce"];
[[NSUserDefaults standardUserDefaults] synchronize];
self.initialViewController = [[InitialViewController alloc] initWithNibName:#"InitialViewController" bundle:nil];
self.window.rootViewController = self.InitialViewController;
NSLog(#"first launch");
}
[self.window makeKeyAndVisible];
return YES;
}
