Why is my method not found?

I have a custom init method for my SecondViewController : UIViewController

-(id) initWithFirstViewController:(FirstViewController *)theFirstViewController
{
    self = [super init];

    fvc = theFirstViewController;     

    return self;   
}

So in my FirstViewController I call this init method with an instance of the FirstViewController as a parameter. Somewhere else in the SecondViewController I use this passed intance:

[fvc setSomething];

The method is executed but I get a warning:

Method -setSomething not found (return type defaults to id)

How to fix this?

In this case, it's a matter of #importing the corresponding .h file so the compiler knows about the method.

Additionally, you should retain theFirstViewController as chances are that it gets released and a different object is created at exactly the same memory location (to which fvc is still pointing). So you should do fvc = [theFirstViewController retain]; as you are "holding on to" the first view controller (you want to make use of it later on). Don't forget to release it in your dealloc.
