How do I change placeholder's title and subtitle when I am calling showNoConnectionPlaceholder() and others?

[junweimah]

I have a simple question, sorry for being a ios newbie.

How do I change the title and sub title wording as I am displaying the placeholders?

I found out that the wordings are in PlaceholderData.swift, in public struct PlaceholderData.

Lets say I do not wish to hard code them here, but set it to something when I am calling tableView.showNoConnectionPlaceholder(), how do I do it?

I also found the file PlaceholdersProvider.swift, which I set it to be :

var noConnectionData: PlaceholderData = .noConnection
        noConnectionData.image = #imageLiteral(resourceName: "hg_default-error")
        noConnectionData.title = "Testing no connection title"
        noConnectionData.subtitle = "Testing no connection sub title"
        let noConnection = Placeholder(data: noConnectionData, style: commonStyle, key: .noConnectionKey)

But the message is still the same

How do I do it?

Thanks

Hi @junweimah,
Thank you for your question.
You could find below an example to change the title of the default theme:

let provider: PlaceholdersProvider = .default
 
var noResultsData: PlaceholderData = .noResults
noResultsData.title = "My custom title"
let noResultsPlaceholder = Placeholder(data: noResultsData, style: PlaceholderStyle(), key: .noResultsKey)
provider.add(placeholders: noResultsPlaceholder)
        
placeholderTableView?.placeholdersProvider = provider

This is what you are looking for ?

@HamzaGhazouani
I will test it out and get back to you

[junweimah]

Where should I place this code in?

[HamzaGhazouani]

You can put it in the viewDidLoad for example

[junweimah]

I tried in viewDidLoad, but nothing is showing

[HamzaGhazouani]

can you please share the code of your controller ?

[junweimah]

in viewDidLoad

if Connectivity.isConnectedToInternet { //tested, working with wifi, not yet tested with mobile data
            print("*** phone is Connected to the internet ")            
        }
        else{
            print("*** phone is Not connected to the Internet")
            //test a custom placeholder
            let provider: PlaceholdersProvider = .default
            
            var noResultsData: PlaceholderData = .noResults
            noResultsData.title = "My custom title"
            let noResultsPlaceholder = Placeholder(data: noResultsData, style: PlaceholderStyle(), key: .noResultsKey)
            provider.add(placeholders: noResultsPlaceholder)
            
            self.tvBug.placeholdersProvider = provider
//            tvBug.showNoConnectionPlaceholder()
        }

Edit:

if I am using tvBug.showNoConnectionPlaceholder(), then it works, but using the default wording

[HamzaGhazouani]

Try this:

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

if Connectivity.isConnectedToInternet == false { //tested, working with wifi, not yet tested with mobile data
    tvBug.showNoConnectionPlaceholder()
}

[junweimah]

Wow, it works!

Thanks !

So I have to have the whole block of code to cuztomize it :

let provider: PlaceholdersProvider = .default
var noConnectionData: PlaceholderData = .noConnection
noConnectionData.title = "My custom title"
let noConnectionPlaceholder = Placeholder(data: noConnectionData, style: PlaceholderStyle(), key: .noConnectionKey)
provider.add(placeholders: noConnectionPlaceholder)
self.tvBug.placeholdersProvider = provider

and then finally use it when I want to display using :

tvBug.showNoConnectionPlaceholder()

correct?

I will find a way to further simplify the code.

Thanks!

Yes exactly, any PR is welcome ;)

In this way,
This will add place holder every time when you call it.
This is not a solution.
It suppose to be have a flexibility to pass, "Title", "Subtitle", "Action" bla bla bla, In custom placeHolder like,

self.tableView_.showLoadingPlaceholder(title: "This is optional Title", subtitle: "This is optional Subtitle", action: "This is optional action")

[umair2ooo]

It will be good if you put it at high priority,
We need it ASAP
