Adding Video as a splash in storyboard ios7 - objective-c

Question

I want to show a video at the beginning of the application start, just like a splash. My whole app will be in Navigation. First, i add the video in a splashViewController and set it in appDelegate as rootView and then simply set the mainViewController as rootView again.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:#"Main" bundle: nil];
splashViewController = [[SplashViewController alloc] init];
splashViewController = (SplashViewController *)[mainStoryboard instantiateViewControllerWithIdentifier:#"SplashViewController"];
self.window.rootViewController = splashViewController;
[NSTimer scheduledTimerWithTimeInterval:9.0 target:self selector:#selector(removeSplashScreen:) userInfo:nil repeats:NO];
return YES;
}
-(void)removeSplashScreen:(id)userInfo
{
[splashViewController removeFromParentViewController];
UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:#"Main" bundle: nil];
mainViewController = [[MainViewController alloc] init];
mainViewController = (MainViewController *)[mainStoryboard instantiateViewControllerWithIdentifier:#"MainViewController"];
self.window.rootViewController = mainViewController;
}
Now i want to start navigation from this mainViewController. I use storyBoard & add navigation from Editor > Embed in > Navigation Controller in mainViewController. Don't do it programmatically. But i know the way of implementing it using Nib.xib. Here i also put the arrow(The arrow which indicate the starting VC) mark besides of it. But it getting crash when i click a button from mainVC to go next VC. How can i set the navigation here?
If any one have the answer, please share with me. Thanks a lot in Advance.

Answer 1

happy to help you here in two steps
step 1-
your didFinishLaunchingWithOptions code is almost correct , but it does not matter if its working . so let focus on step two.
step 2- in -(void)removeSplashScreen:(id)userInfo
-first line is good , but you even dont need it because you are going to switch the root controller (leave it for now)
- second line (no need to write it)
- third line is really bad , what you doing here is trying to alloc you mainviewcontroller. really you need it with storyboard? no
- you should load you main view controller from storyboard
MainViewController* mainViewController = (MainViewController *)[mainStoryboard instantiateViewControllerWithIdentifier:#"MainViewController"];
"this line is enough to load your main view controller from storyboard"
-next line is correct
self.window.rootViewController = mainViewController;
code seems to be working now , but still you are missing navigation controller because you have loaded mainviewcontroller from storyboard, not the navigation controller.
- two solution for it
1- load navigation controller in place of mainviewcontroller(give a storyboard id to navigation controller , load it , and make it as root controller) --i will always go with it
2- make a navigation controller with allocating it & make its rootviewcontroller the mainviewcontroller

Answer 2

Ok Despite my advice (in the comments), here is how you can achieve this:
Display splash:
//StoryBoard
UIStoryboard *mainStoryboard = [UIStoryboard
storyboardWithName:#"Main" bundle: nil];
//Splash Controller
SplashViewController *splashViewController = [mainStoryboard
instantiateViewControllerWithIdentifier:#"SplashViewController"];
//Show it
[self.window.rootViewController presentViewController:splashViewController
animated:NO completion:nil];
Remove it:
[self dismissViewControllerAnimated:YES completion:nil];
EDIT: Still not working?
Maybe you called it to quick. do this:
viewDidLoad:
[NSTimer scheduledTimerWithTimeInterval:9.0
target:self
selector:#selector(removeSplashScreen:)
userInfo:nil repeats:NO];
function to remove:
-(void)removeSplashScreen:(id)userInfo
{
[self dismissViewControllerAnimated:YES completion:nil];
}

So the solution, according to pawan's given answer is :
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:#"Main" bundle: nil];
splashViewController = (SplashViewController *)[mainStoryboard instantiateViewControllerWithIdentifier:#"SplashViewController"];
self.window.rootViewController = splashViewController;
[NSTimer scheduledTimerWithTimeInterval:9.0 target:self selector:#selector(removeSplashScreen:) userInfo:nil repeats:NO];
return YES;
}
-(void)removeSplashScreen:(id)userInfo
{
UIStoryboard *mainStoryboard = [UIStoryboard storyboardWithName:#"Main" bundle: nil];
mainViewController = [[MainViewController alloc] init];
mainViewController = (MainViewController *)[mainStoryboard instantiateViewControllerWithIdentifier:#"MainViewController"];
navigationContoller = [[UINavigationController alloc] initWithRootViewController:mainViewController];
self.window.rootViewController = navigationContoller;
}
