Hi guys, I've searched and read and still haven't found a concrete answer.

Brief: I have an application where I declare an NSMutableArray in my AppDelegate to synthesize when the application loads. (code below). I have a SecondaryViewController call this function, and I have it output a string to let me know what the array size is. Every time I run it, it executes but it does not add any objects to the array. How do I fix this?

AppDelegate.h file

#import <UIKit/UIKit.h>

@class arrayTestViewController;

@interface arrayTestAppDelegate : NSObject <UIApplicationDelegate> {
    UIWindow *window;
    arrayTestViewController *viewController;

    NSMutableArray *myArray3;
}

@property (nonatomic, retain) NSMutableArray *myArray3;
@property (nonatomic, retain) IBOutlet UIWindow *window;
@property (nonatomic, retain) IBOutlet arrayTestViewController *viewController;

-(void)addToArray3;

@end

AppDelegate.m file

#import "arrayTestAppDelegate.h"
#import "arrayTestViewController.h"

@implementation arrayTestAppDelegate

@synthesize window;
@synthesize viewController;
@synthesize myArray3;

#pragma mark -
#pragma mark Application lifecycle



- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    
    myArray3 = [[NSMutableArray alloc] init];


    // Override point for customization after application launch.

    // Add the view controller's view to the window and display.
    [window addSubview:viewController.view];
    [window makeKeyAndVisible];

    return YES;
}

-(void)addToArray3{

    NSLog(@"Array Count: %d", [myArray3 count]);
    [myArray3 addObject:@"Test"];
    NSLog(@"Array triggered from SecondViewController");
    NSLog(@"Array Count: %d", [myArray3 count]);


}

SecondViewController.m file

#import "SecondViewController.h"
#import "arrayTestAppDelegate.h"

@implementation SecondViewController



-(IBAction)addToArray{
    arrayTestAppDelegate *object = [[arrayTestAppDelegate alloc] init];
    [object addToArray3];
}
