iphone dev create an array accessable from a number of View Controllers

I have an array arryImages which I would only like to declare once and access it from a number of view controllers, but I can't figure out where to place it.

I have a separate class (Variables.m) which contains the following code

 @implementation Variables

//images array
arryImages = [NSArray arrayWithObjects:
              [UIImage imageNamed: @"ico-company.png"],
              [UIImage imageNamed: @"ico-value.png"],
              [UIImage imageNamed: @"ico-date.png"],
              [UIImage imageNamed: @"ico-notes.png"], nil];

@end

In my viewcontroller class (which I want to access the array) I have ad开发者_如何学Goded:

#import "Variables.h"

I tried playing with @synthesize, but I can't access the array arrayImages.

(Using the call imageView2.image = [arryImages objectAtIndex:[indexPath row]];) Ps. this works perfect when its just above the code, but not in a separate class.

What am I missing?

You should declare your array as a property. Synthesize it and initialize in your ViewDidLoad Method.

i.e. the header

@interface AddFriendViewController : UIViewController {
 NSArray *arryImages;
}

@property (nonatomic, retain) NSarray *arryImages ;

@end

the implementation:

@synthesize arryImages;

- (void)viewDidLoad {
    [super viewDidLoad];
    arryImages = [NSArray arrayWithObjects:
          [UIImage imageNamed: @"ico-company.png"],
          [UIImage imageNamed: @"ico-value.png"],
          [UIImage imageNamed: @"ico-date.png"],
          [UIImage imageNamed: @"ico-notes.png"], nil];
}

If you want to share a variable between views, you should put in your app delegate and access it from there.

NSArray *arryImages = [(MyAppDelegate *)[[UIApplication sharedApplication] delegate] arryImages];
