Use a singleton class, I use them all the time for global data manager classes that need to be accessible from anywhere inside the application. You can create a simple one like this:

@interface NewsArchiveManager : NetworkDataManager
{
}

+ (NewsArchiveManager *) sharedInstance;
@end

@implementation NewsArchiveManager

- (id) init
{
    self = [super init];
    if ( self ) 
    {
         // custom initialization goes here
    }

    return self;
}


+ (NewsArchiveManager *) sharedInstance
{
    static NewsArchiveManager *g_instance = nil;

    if ( g_instance == nil )
    {
        g_instance = [[self alloc] init];
    }

    return g_instance;
}


- (void) dealloc
{
    [super dealloc];
}

@end
