Question

Im new to Objective and iPad apps. Im trying to display an array that Ive already used in a separate Class/View Controller. The array Im trying to access is in “MainMenuScreen.m” and I want to use that array in another class called “ScoresScreen.m”.
All my code is working, I just need to get the array from the other class and plug into my code.I tried using Segue but im getting this error in my code, and im stuck. Thankyou in advance

Use this in your MainMenuScreen.m file

#import "MainMenuScreen.h"
#import "PlayGame.h"
#import "ImageTest.h"
#import "ScoreScreen.h"
