Buttons on Bulletin do not work

[docash59]

Problem Description:
The action buttons/handlers do not work.

Steps to reproduce:

1. Install via Pods
2. @import BLTNBoard

    BLTNPageItem *page = [[BLTNPageItem alloc] initWithTitle:@"Notifications"];
    page.descriptionText = @"Receieve latest news.";
    page.actionButtonTitle = @"Allow";
    page.alternativeButtonTitle = @"Decide later";
    
    page.actionHandler = ^(BLTNActionItem * _Nonnull _item) {
        [self requestNotifications];
    };
    
    BLTNPageItem *introPage = page;
    BLTNItemManager *man = [[BLTNItemManager alloc] initWithRootItem:introPage];
    
    [man showBulletinAboveViewController:self animated:YES completion:nil];

4. Launch the app
5. Tap Allow on the BulletinBoard
6. Nothing happens. Tapping the ( X ) in the top right doesn't commit any action either.

Environment:

• Device: iPhone X
• OS: iOS 12.1.x / Xcode 10.1
• Version of BulletinBoard: 3.0.0

This issue happens to me just sometimes, not yet sure why. I am using carthage btw.

Same for me - tapping the ( X ) does nothing, same with the other buttons. It looks like the BLTNItemManager is nil at the moment the ( X ) is being pressed, and thus the view can't be dismissed.

It is a common error for people who use the library: you need to retain the manager as a property, usually on the view controller that presents it.

Another possibility... If you are overriding the setUp method, make sure you call super.setUp() or [super setUp]. This is where the action button gets wired up and if you forget to call the super method it doesn't work.

Understood thank you. Have tried again and the BLTNBoard now works, thank you!

Can you expand on what you mean by "you need to retain the manager as a property, usually on the view controller that presents it."? Can you give some example code. I've tried doing the following on the presenting viewcontroller but that doesn't fix it. Not sure how else to do it?
lazy var bulletinManager: BLTNItemManager = {
let introPage = BulletinDataSource.makeIntroPage()
let manager = introPage.manager
return BLTNItemManager(rootItem: introPage)
}()

Follow on from the above comment, this is the code of the root item:
static func makeIntroPage() -> BLTNPageItem {

    let page = BLTNPageItem(title: "Boost your creativity and improve your writing ability")
    page.appearance.titleTextColor = UIColor(red: 34/256, green: 34/256, blue: 34/256, alpha: 1)
    page.appearance.titleFontSize = 25
    page.descriptionText = "Daily Prompt helps you get into the habit of creating beautiful works of art every day.\n\n\n\n"
    
    page.actionButtonTitle = "Continue"
    page.appearance.actionButtonColor = UIColor(red: 111/256, green: 101/256, blue: 215/256, alpha: 1)
    page.appearance.actionButtonFontSize = 22
    page.isDismissable = false
    
    page.actionHandler = { item in
        item.manager?.displayNextItem()
    }
    
    page.next = newPromptdaily()
    
    return page
}
