Q:Controller present 2 second , how to make it looks like only one transition?

Question

I have a requirement, Controller1 present to -> Controller2 -> present to Controller3, how to make it looks like Controller1 present to -> Controller3?

You know the requirement is when I start my app, it will first in LaunchController then LoginController, and at last it present to MainController,but when I second time to start my app, it looks like from LaunchController present to MainController, because I saved the username and password in my sandbox. How to realize the function?

Answer 1

You can set the rootviewcontroller of your application window to your MainController directly the second time; when you have username & password. Something like this:

if(username && password)
        [self.window setRootViewController:[[MainController alloc] initWithNibName:@"MainController" bundle:nil]];

You can do this inside

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
