Hello, everyone,
I’ve been have problems using the purchase functionality.
What i want to do is:
user go to store, buy some lives, and write the lives in a file.
I already tested using test flight but doesn’t appear the popup with the product name, product price, and buy button.
Anyone knows how to implement in-app purchases? i’m trying implement for app store.
Regards,
Miguel Lima
I’m assuming you’re asking about IAP for iOS. If I understand correctly, if someone buys an IAP through the App Store app, the first time your app runs and you initialize the store, you will get purchase transactions sent to your transaction listener. Your app would react to those purchases and you could add lives as if they made the IAP from within your app.

Yes Rob, i’m using the map badger plugin, and works okay one the corona simulator and xcode simulator, but when i try using testflight , when i click in the product i want to purchase, request for user enter the password but doesn’t do nothing more .
Rob can you tell me what is wrong?

First and foremost, you should always post code to the forums using code formatting. The easiest way to do this is to use the blue <> button in the row with Bold and Italic. Then paste your code into the popup window. Your code when not formatted is very hard to read.
Secondly, this isn’t a problem, but it causes confusion, is you have two transaction listener functions.
Third, you’re granting additional lives before the purchase is made. I would defer this action until you get a “purchased” transaction, determine what was purchased then grant the lives.
Your saveLives function is defined local but defined after you use it the first time. This could be a problem. Please move that function above your transaction processing function.
Finally, you should be printing out more information to determine what is going on:
local function transactionListener( event ) local transaction = event.transaction print("transaction.state", transaction.state) if ( transaction.isError ) then print( transaction.errorType ) print( transaction.errorString ) else -- No errors; proceed if ( transaction.state == "purchased" or transaction.state == "restored" ) then -- Handle a normal purchase or restored purchase here print( transaction.state ) print( transaction.productIdentifier ) print( transaction.date ) local storeAddLives = composer.getVariable("lives") table.remove(settings,3) table.insert( settings, 3, storeAddLives ) saveLives() elseif ( transaction.state == "cancelled" ) then -- Handle a cancelled transaction here elseif ( transaction.state == "failed" ) then -- Handle a failed transaction here end -- Tell the store that the transaction is complete -- If you're providing downloadable content, do not call this until the download has completed store.finishTransaction( transaction ) end end

First and foremost, you should always post code to the forums using code formatting. The easiest way to do this is to use the blue <> button in the row with Bold and Italic. Then paste your code into the popup window. Your code when not formatted is very hard to read.
Secondly, this isn’t a problem, but it causes confusion, is you have two transaction listener functions.
Third, you’re granting additional lives before the purchase is made. I would defer this action until you get a “purchased” transaction, determine what was purchased then grant the lives.
Your saveLives function is defined local but defined after you use it the first time. This could be a problem. Please move that function above your transaction processing function.
Finally, you should be printing out more information to determine what is going on:
local function transactionListener( event ) local transaction = event.transaction print("transaction.state", transaction.state) if ( transaction.isError ) then print( transaction.errorType ) print( transaction.errorString ) else -- No errors; proceed if ( transaction.state == "purchased" or transaction.state == "restored" ) then -- Handle a normal purchase or restored purchase here print( transaction.state ) print( transaction.productIdentifier ) print( transaction.date ) local storeAddLives = composer.getVariable("lives") table.remove(settings,3) table.insert( settings, 3, storeAddLives ) saveLives() elseif ( transaction.state == "cancelled" ) then -- Handle a cancelled transaction here elseif ( transaction.state == "failed" ) then -- Handle a failed transaction here end -- Tell the store that the transaction is complete -- If you're providing downloadable content, do not call this until the download has completed store.finishTransaction( transaction ) end end
