Action button is not visible, but tapping on the white space is printing logs.

[junweimah]

Hi,

I played around the example project and found that the placeholder has a button "try again", and user can tap that.

However in my project, there is no action button, but I can tap on the white space below the subtitle and the log is printing "Placeholder action button tapped"

How and where do I set the action button to visible?

Thanks

Hi @junweimah, the background color of the action button, by default, is the tintColor of the TableView, just change it. Or if you would like to customize it you can use PlaceholderStyle

How do I use PlaceholderStyle?

In other question, you guided me to this code :

//test a custom placeholder
            let provider: PlaceholdersProvider = .default
            var noConnectionData: PlaceholderData = .noConnection
            noConnectionData.title = "My custom title"
            noConnectionData.subtitle = "Please check your connection !!! "
            
            let noConnectionPlaceholder = Placeholder(data: noConnectionData, style: PlaceholderStyle(), key: .noConnectionKey)
            provider.add(placeholders: noConnectionPlaceholder)
            self.tvBug.placeholdersProvider = provider

Now in let noConnectionPlaceholder = Placeholder(data: noConnectionData, style: PlaceholderStyle(), key: .noConnectionKey), for PlaceholderStyle() I have to cuztomize right?

What do I need to do to change the text and background color of the action button?

[HamzaGhazouani]

So to customize the style you can do like that :

//test a custom placeholder
let provider: PlaceholdersProvider = .default
var noConnectionStyle = PlaceholderStyle()
noConnectionStyle.actionBackgroundColor = .red
...
var noConnectionData: PlaceholderData = .noConnection
noConnectionData.title = "My custom title"
noConnectionData.subtitle = "Please check your connection !!! "
    
let noConnectionPlaceholder = Placeholder(data: noConnectionData, noConnectionStyle: , key: .noConnectionKey)
provider.add(placeholders: noConnectionPlaceholder)
self.tvBug.placeholdersProvider = provider

Wow. it works! Thanks

For the action button tap function

func view(_ view: Any, actionButtonTappedFor placeholder: Placeholder) {
        //do something here
        print("this is placeholder tapped !!! ")
    }

Why is this not printed out?

Only "Placeholder action button tapped" bring printed out, and that can be traced back to PlaceholderTableViewCell.swift :

@IBAction func sendPlaceholderAction(_ sender: Any) {
        onActionButtonTap?()
        print("Placeholder action button tapped")
    }

You are welcome :)
It's not printed out because your controller is not conform to the protocol PlaceholderDelegate:

extension ViewController: PlaceholderDelegate {
    
    func view(_ view: Any, actionButtonTappedFor placeholder: Placeholder) {
        print(placeholder.key.value)
        placeholderTableView?.showDefault()
    }
}

My vc actually have this right now

class BugTabTableViewController: UITableViewController, IndicatorInfoProvider, PlaceholderDelegate{

func view(_ view: Any, actionButtonTappedFor placeholder: Placeholder) {
      //do something here
      print("this is in big tv vc placeholder tapped !!! ")
      print("this is key value \(placeholder.key.value)")
//        self.tvBug.showDefault()
  }

However this is not printed out

Hi @junweimah,

I think you missed to set the placeholderDelegate to self:
tvBug.placeholderDelegate = self

[junweimah]

WOW.

Thanks. It works!
