Question

I am trying to create an array of views that I can then swipe though in my applicant.

I have tried to set up my array in my view did load then load the first view in the array into view.

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view from its nib.
    self.title = @"Prototype";
    //Initalizse the swipe gestuer listener
    [self setupLeftSwipeGestureRecognizer];
    [self setupRightSwipeGestureRecognizer];

    //alloc and init viewcontroller nibs
    self.detailViewA = [[DetailViewController alloc]initWithNibName:@"DetailViewController" bundle:[NSBundle mainBundle]]; 
    self.detailViewB = [[DetailViewControllerB alloc]initWithNibName:@"DetailViewControllerB" bundle:[NSBundle mainBundle]];
    self.detailViewC = [[DetailViewControllerC alloc]initWithNibName:@"DetailViewControllerC" bundle:[NSBundle mainBundle]];
    // Create Array
    viewArray = [NSArray arrayWithObjects:detailViewA_, detailViewB_, detailViewC_, nil];

    // set detail View as first view
    [self.view addSubview:[viewArray objectAtIndex:0]];

}

After which it crashes. and produces this message.

Answer 1

You are adding a view controller as a subview but what you need to do is add the view of that viewController.

UIViewController *tempVC = (UIViewController*)[viewArray objectAtIndex:0];
[self.view addSubView:tempVC.view];
