iOS IAP issues

Hello!

IAP work like a charm on Android but on iOS I can’t load the products.
Here is that part of my code.

local productIdentifiers = {
	"com.mycompany.mygame.purchase",
}
	
local function productListener( event )
	for i = 1,#event.products do 
	    local plistener = native.showAlert( event.products[i].productIdentifier, "Οκ!", { "Back" } )
	    end	
	end
end
	
local function transactionListener( event )
	if ( event.name == "init" ) then
	    store.loadProducts( productIdentifiers, productListener )
	 end
end

store.init( transactionListener )

The weird thing is that a few days ago this code was working!
I did my purchases / restores in Testflight!

Try adding this to your transaction listener:

if ( ( transaction and transaction.isError ) or event.isError ) then
     native.showAlert( ":(", "This is an error", { "Got it" } )
elseif ( event.name == "init" ) then
     store.loadProducts( productIdentifiers, productListener )
end

I will implement your code in a few minutes!

Also it could be this :slight_smile:

Thank you!!

Yes, I’ve received that message with some of my apps. Don’t bother about it. You don’t need to do anything. If your code is well implemented, the IAP can be tested in the test environment.

It worked, thank you so much :)!!!

May I ask about receipt validation.
Is it mandatory to be implemented?
Will an update be rejected if not implemented?

When a user is performing a non-consumable purchase I make it very clear that the purchase has been completed by showing on screen message and changing the purchase button to a “bought” image.

Now I got problem handling transaction states purchased and restored.
Could you please share some general code for those too?

Here is my code focused on restore purchases

-- product identifiers
local productIdentifiers = {
	"com.mydomain.mygame.testiap"
}

-- product listend
local function productListener( event )
	for i = 1,#event.products do
		print( event.products[i].productIdentifier )
	end
end
	
-- transaction listener
local function transactionListener( event )
	if ( ( transaction and transaction.isError ) or event.isError ) then
    		native.showAlert( ":(", "This is an error", { "Got it" } )
	elseif ( event.name == "init" ) then
    		store.loadProducts( productIdentifiers, productListener )
	elseif ( event.name == "storeTransaction" ) then
	    if not ( event.transaction.state == "failed" ) then  -- Successful transaction
            if (event.transaction.state == "restoreCompleted") then
				if event.transaction.productIdentifier == "com.mydomain.mygame.testiap" then
					print("restore completed") -- this is never triggered because can't get event.transaction.productIdentifier
							
					store.finishTransaction( "com.mydomain.mygame.testiap" )
				else
					print("no previously purchases") -- always triggered	
				end
			elseif event.transaction.state == "failed" then
				store.finishTransaction( "com.mydomain.mygame.testiap" )
	
	        else  
	           	store.finishTransaction( "com.mydomain.mygame.testiap" )
	        end
        else 
            store.finishTransaction( "com.mydomain.mygame.testiap" )
        end
	end
end

-- initialization
store.init( transactionListener )

Thank you!

I think I have fixed it although I will probably use iap_badger.

Sorry for the delay. The receipt validation is not mandatory.

Note that when the state of a transaction is “failed” you got and error, so the condition if not ( transaction.state == "failed" then inside “init” is not necessary

Changing your code:


-- transaction listener
local function transactionListener( event )
    local transaction = event.transaction
    if ( ( transaction and transaction.isError ) or event.isError ) then
        native.showAlert( ":(", "This is an error", { "Got it" } )
        
    elseif ( event.name == "init" ) then
        
        store.loadProducts( productIdentifiers, productListener )
        
    elseif ( event.name == "storeTransaction" ) then
        
        if transaction.state == "purchased" then
            
            --
        elseif transaction.state == "restoreCompleted" then
            
            if transaction.productIdentifier == "com.mydomain.mygame.testiap" then
                print("restore completed") -- this is never triggered because can't get event.transaction.productIdentifier
            end
            
        elseif transaction.state == "failed" then
            print ( "Transaction failed" )
        end
        
        store.finishTransaction( transaction )
        
    end
end
