Swift: Buttons not working

[simongiesen]

Hi everybody!

I try to add an action handler and alternative handler. It does not work ... Can anybody help me?

let bulletinManager: BLTNItemManager = {
let rootItem = BLTNPageItem(title: "Welcome")

        rootItem.descriptionText = "Would you like to add Sample Data to your database?"
        rootItem.actionButtonTitle = "Add"
        rootItem.alternativeButtonTitle = "Not now"
        rootItem.isDismissable = false
        
        rootItem.actionHandler = { (item: BLTNActionItem) in
            item.actionButtonTitle = "tapped"
        }
        
        
        
        rootItem.alternativeHandler = { (item: BLTNActionItem) in
            print("Alternative button tapped")
        }
        
            return BLTNItemManager(rootItem: rootItem)
        }()

Hi there, what version are you using? Does the issue reproduce with 5.0.0-rc.2?

I cannot reproduce the issue. If you could provide more details about how you present the bulletin it would be really helpful!

below is the code snippet i am using for button actions handling in iOS 14 , simulator + tableview on Xcode 12 with latest version of your POD.

` func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
let cell = scheduleTableMain.dequeueReusableCell(withIdentifier: "schCell" , for: indexPath) as! ScheduleTableViewCell
let classes : ScheduleClasses

    classes = classList[indexPath.row]
    let boardManagere : BLTNItemManager = {
        
        let item = BLTNPageItem(title: classes.name)
        item.requiresCloseButton = false
        item.descriptionText = classes.description
        //item.image = UIImage(named: "circleLogo")
        item.actionButtonTitle = "Join Class"
        item.alternativeButtonTitle = "More Info"
        item.isDismissable = true
        item.appearance.actionButtonColor = UIColor(named: "someCyan") ?? UIColor.blue
        item.actionHandler = {(item: BLTNActionItem) in
                print("Action button tapped")
        }
        item.alternativeHandler = {(item: BLTNActionItem) in
            print("Action button tapped")
        }
        
        return BLTNItemManager(rootItem: item)
        
    }()
    boardManagere.backgroundViewStyle = .blurredDark
    boardManagere.showBulletin(above: self)

} `

Screenshot of text being fetched over the title and i need that join button to be working that is really important :)

@rdunlocked18 Ah okay - so the issue here is that you don’t keep a reference to the bulletin manager. The object gets deallocated when the table view delegate method returns. You need to keep a reference to it, you can look at the example project to see how it’s done.

@simongiesen it’s probably the same issue for you, actually. Can you double check?

i need to trigger BLTN on TableView Click can u hint me out how can i ?.. even if i lazy var it in the class the extension wont let the vars get through the mainClass so what should i do ? where should i create a reference of BLTNItemManager to get it onClick of tableView single cell .. i am a bit new in iOS

[alexaubry]

You can have an optional variable on the class that’s presenting it:

var bulletinManager: BLTNManager?

and set it in did tap table view cell after you create it:

let bulletinManager = ... (your code snippet)
self. bulletinManager = bulletinManager

And once you dismiss it, call that in the dismissal handler:

self.bulletinManager = nil

Again, please look at the example project for help with the dismissal handlers and setting up the project.
