It sounds like you're missing a return statement on a method or something like that. Check in your .h file and make sure that every method you define has a matching implementation in your .m (or .mm) file. And then make sure they each return the value they say they will return. For instance,

-(BOOL)someRandomMethod:(NSString *)inputString {

    // Test the input string

    return TRUE;
}

Obviously -(void) will not need to return anything.
