How to check your current rootViewController and use it in an if statement :

// Get your current rootViewController
NSLog(@"My current rootViewController is: %@", [[[UIApplication sharedApplication].delegate.window.rootViewController class]);

// Use in an if statement
UIViewController *rootViewController = [UIApplication sharedApplication].delegate.window.rootViewController;
if ([rootViewController isKindOfClass:[MyViewController class]])
{
    NSLog(@"Your rootViewController is MyViewController!!");
}

The navigation controllers root view controller is,

id rootVC = [[navigationController viewControllers] objectAtIndex:0];

And check the class of rootVC like this,

if ([rootVC isKindOfClass:[YourClass class]]) {

Perhaps you can use the method isKindOfClass

[rootViewController isKindOfClass: [RootViewController class]];

You can check the class with:

if ([rootViewController isKindOfClass:[YourClass class]]){

}else if ([rootViewController isKindOfClass:[AnotherClass class]]){

}else{
}
