Add view controllers to array
<p>How can i add these four view controllers to array</p>

<pre><code>self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]autorelease];    
ContainerViewController  *container= [[[ContainerViewController alloc]init]autorelease];
self.window.rootViewController = container;  
NSMutableArray *controllers = [NSMutableArray array];
for (int i=0; i&lt;23; i++)
{
    First *first = [[First alloc] init];
    Second *second = [[Second alloc] init];
    Third *third = [[Third alloc] init];
    Fourth *fourth = [[Fourth alloc] init];

    [controllers addObject:first];
    [controllers addObject:second];
    [controllers addObject:third];
    [controllers addObject:fourth];
    }

 [container setSubViewControllers:controllers];
[window makeKeyAndVisible];
return YES;
</code></pre>

<p>getting yellow warning that instance method setSubViewController not found return type defaults to id</p>

<p>Thanks for help.</p>
