দ্রুত উত্তর
এটি আমার উদ্দেশ্য-সি উত্তর পরিপূরক বোঝাতে সুইফ্ট ব্যবহারকারীদের জন্য , উদ্দেশ্য-সি উত্তরটি খুব বড় হওয়া থেকে রক্ষা করা।
সেটআপ
প্রথমে appstoreconnect.apple.com এ অ্যাপ্লিকেশন কেনা সেট আপ করুন । এটি করার নির্দেশাবলীর জন্য আমার অবজেক্টিভ-সি উত্তরের প্রথম অংশটি অনুসরণ করুন ( অ্যাপ স্টোর কানেক্ট হেডারের অধীনে 1-13 পদক্ষেপ )।
অ্যাপ স্টোর কানেক্টে আপনার পণ্যের আইডি নিবন্ধিত হতে কয়েক ঘন্টা সময় নিতে পারে, তাই ধৈর্য ধরুন।
আপনি এখন অ্যাপ স্টোর কানেক্টে অ্যাপ্লিকেশন কেনার তথ্য সেট আপ করেছেন, অ্যাপ্লিকেশনটিতে অ্যাপ্লিকেশানের ক্রিয়াকলাপের জন্য আমাদের অ্যাপলের ফ্রেমওয়ার্কটি যুক্ত StoreKitকরতে হবে।
আপনার এক্সকোড প্রকল্পে যান এবং অ্যাপ্লিকেশন ম্যানেজারে যান (আপনার অ্যাপ্লিকেশনটির ফাইলগুলি যেখানে বাম বারের শীর্ষে নীল পৃষ্ঠার মতো আইকন)। বাম দিকে লক্ষ্যগুলির অধীনে আপনার অ্যাপ্লিকেশনটিতে ক্লিক করুন (এটি প্রথম বিকল্প হওয়া উচিত), তারপরে উপরের "সক্ষমতা" এ যান। তালিকায় আপনার "বিকল্প অ্যাপ্লিকেশন ক্রয়" বিকল্পটি দেখতে হবে। এই ক্ষমতাটি চালু করুন, এবং এক্সকোড যুক্ত হবেStoreKit আপনার প্রকল্পে ।
আইনসংগ্রহ
এখন, আমরা কোডিং শুরু করতে যাচ্ছি!
প্রথমে একটি নতুন সুইফ্ট ফাইল তৈরি করুন যা আপনার অ্যাপ্লিকেশন-ক্রয়ের সমস্ত পরিচালনা করবে। আমি এটি কল করতে যাচ্ছিIAPManager.swift ।
এই ফাইলের মধ্যে, আমরা একটি নতুন বর্গ, নামক তৈরি করতে যাচ্ছেন IAPManagerযে একটি SKProductsRequestDelegateএবং SKPaymentTransactionObserver। শীর্ষে, নিশ্চিত করুন যে আপনি আমদানি করেন FoundationএবংStoreKit
import Foundation
import StoreKit
public class IAPManager: NSObject, SKProductsRequestDelegate,
SKPaymentTransactionObserver {
}
এরপরে, আমরা আমাদের অ্যাপ্লিকেশন ক্রয়ের জন্য সনাক্তকারীকে সংজ্ঞায়িত করতে একটি ভেরিয়েবল যুক্ত করতে যাচ্ছি (আপনি এমন কোনও ব্যবহার করতে পারেন enumযা আপনার একাধিক আইএপি রাখলে এটি বজায় রাখা আরও সহজ হবে)।
// This should the ID of the in-app-purchase you made on AppStore Connect.
// if you have multiple IAPs, you'll need to store their identifiers in
// other variables, too (or, preferably in an enum).
let removeAdsID = "com.skiplit.removeAds"
আসুন পরবর্তী ক্লাসের জন্য একটি ইনিশিয়ালাইজার যুক্ত করুন:
// This is the initializer for your IAPManager class
//
// A better, and more scaleable way of doing this
// is to also accept a callback in the initializer, and call
// that callback in places like the paymentQueue function, and
// in all functions in this class, in place of calls to functions
// in RemoveAdsManager (you'll see those calls in the code below).
let productID: String
init(productID: String){
self.productID = productID
}
এখন, আমরা SKProductsRequestDelegateএবং এর জন্য প্রয়োজনীয় ফাংশন যুক্ত করতে যাচ্ছিSKPaymentTransactionObserver কাজ করার :
আমরা RemoveAdsManagerক্লাসটি পরে যুক্ত করব
// This is called when a SKProductsRequest receives a response
public func productsRequest(_ request: SKProductsRequest, didReceive response: SKProductsResponse){
// Let's try to get the first product from the response
// to the request
if let product = response.products.first{
// We were able to get the product! Make a new payment
// using this product
let payment = SKPayment(product: product)
// add the new payment to the queue
SKPaymentQueue.default().add(self)
SKPaymentQueue.default().add(payment)
}
else{
// Something went wrong! It is likely that either
// the user doesn't have internet connection, or
// your product ID is wrong!
//
// Tell the user in requestFailed() by sending an alert,
// or something of the sort
RemoveAdsManager.removeAdsFailure()
}
}
// This is called when the user restores their IAP sucessfully
private func paymentQueueRestoreCompletedTransactionsFinished(_ queue: SKPaymentQueue){
// For every transaction in the transaction queue...
for transaction in queue.transactions{
// If that transaction was restored
if transaction.transactionState == .restored{
// get the producted ID from the transaction
let productID = transaction.payment.productIdentifier
// In this case, we have only one IAP, so we don't need to check
// what IAP it is. However, this is useful if you have multiple IAPs!
// You'll need to figure out which one was restored
if(productID.lowercased() == IAPManager.removeAdsID.lowercased()){
// Restore the user's purchases
RemoveAdsManager.restoreRemoveAdsSuccess()
}
// finish the payment
SKPaymentQueue.default().finishTransaction(transaction)
}
}
}
// This is called when the state of the IAP changes -- from purchasing to purchased, for example.
// This is where the magic happens :)
public func paymentQueue(_ queue: SKPaymentQueue, updatedTransactions transactions: [SKPaymentTransaction]){
for transaction in transactions{
// get the producted ID from the transaction
let productID = transaction.payment.productIdentifier
// In this case, we have only one IAP, so we don't need to check
// what IAP it is.
// However, if you have multiple IAPs, you'll need to use productID
// to check what functions you should run here!
switch transaction.transactionState{
case .purchasing:
// if the user is currently purchasing the IAP,
// we don't need to do anything.
//
// You could use this to show the user
// an activity indicator, or something like that
break
case .purchased:
// the user successfully purchased the IAP!
RemoveAdsManager.removeAdsSuccess()
SKPaymentQueue.default().finishTransaction(transaction)
case .restored:
// the user restored their IAP!
IAPTestingHandler.restoreRemoveAdsSuccess()
SKPaymentQueue.default().finishTransaction(transaction)
case .failed:
// The transaction failed!
RemoveAdsManager.removeAdsFailure()
// finish the transaction
SKPaymentQueue.default().finishTransaction(transaction)
case .deferred:
// This happens when the IAP needs an external action
// in order to proceeded, like Ask to Buy
RemoveAdsManager.removeAdsDeferred()
break
}
}
}
এখন আসুন এমন কয়েকটি ফাংশন যুক্ত করুন যা ক্রয় শুরু করতে বা পুনরুদ্ধার করা ক্রয় শুরু করতে ব্যবহৃত হতে পারে:
// Call this when you want to begin a purchase
// for the productID you gave to the initializer
public func beginPurchase(){
// If the user can make payments
if SKPaymentQueue.canMakePayments(){
// Create a new request
let request = SKProductsRequest(productIdentifiers: [productID])
// Set the request delegate to self, so we receive a response
request.delegate = self
// start the request
request.start()
}
else{
// Otherwise, tell the user that
// they are not authorized to make payments,
// due to parental controls, etc
}
}
// Call this when you want to restore all purchases
// regardless of the productID you gave to the initializer
public func beginRestorePurchases(){
// restore purchases, and give responses to self
SKPaymentQueue.default().add(self)
SKPaymentQueue.default().restoreCompletedTransactions()
}
এর পরে, আমাদের আইএপিগুলি পরিচালনা করতে একটি নতুন ইউটিলিটি ক্লাস যুক্ত করা যাক। এই কোডটি সমস্তই একটি শ্রেণিতে থাকতে পারে, তবে এটির একাধিক হওয়া এটিকে একটু পরিষ্কার করে তোলে। আমি একটি নতুন ক্লাস তৈরি করতে যাচ্ছি RemoveAdsManager, এবং এটিতে কয়েকটি ফাংশন রেখেছি
public class RemoveAdsManager{
class func removeAds()
class func restoreRemoveAds()
class func areAdsRemoved() -> Bool
class func removeAdsSuccess()
class func restoreRemoveAdsSuccess()
class func removeAdsDeferred()
class func removeAdsFailure()
}
প্রথম তিনটি ফাংশন, removeAds, restoreRemoveAds, এবং areAdsRemoved, ফাংশন যে আপনি নির্দিষ্ট কর্ম করতে ডাকবো হয়। শেষ চারটি এক দ্বারা ডাকা হবে IAPManager।
প্রথম দুটি ফাংশনে কিছু কোড যুক্ত করা যাক removeAdsএবং restoreRemoveAds:
// Call this when the user wants
// to remove ads, like when they
// press a "remove ads" button
class func removeAds(){
// Before starting the purchase, you could tell the
// user that their purchase is happening, maybe with
// an activity indicator
let iap = IAPManager(productID: IAPManager.removeAdsID)
iap.beginPurchase()
}
// Call this when the user wants
// to restore their IAP purchases,
// like when they press a "restore
// purchases" button.
class func restoreRemoveAds(){
// Before starting the purchase, you could tell the
// user that the restore action is happening, maybe with
// an activity indicator
let iap = IAPManager(productID: IAPManager.removeAdsID)
iap.beginRestorePurchases()
}
এবং সর্বশেষে, আসুন শেষ পাঁচটি ফাংশনে কিছু কোড যুক্ত করব।
// Call this to check whether or not
// ads are removed. You can use the
// result of this to hide or show
// ads
class func areAdsRemoved() -> Bool{
// This is the code that is run to check
// if the user has the IAP.
return UserDefaults.standard.bool(forKey: "RemoveAdsPurchased")
}
// This will be called by IAPManager
// when the user sucessfully purchases
// the IAP
class func removeAdsSuccess(){
// This is the code that is run to actually
// give the IAP to the user!
//
// I'm using UserDefaults in this example,
// but you may want to use Keychain,
// or some other method, as UserDefaults
// can be modified by users using their
// computer, if they know how to, more
// easily than Keychain
UserDefaults.standard.set(true, forKey: "RemoveAdsPurchased")
UserDefaults.standard.synchronize()
}
// This will be called by IAPManager
// when the user sucessfully restores
// their purchases
class func restoreRemoveAdsSuccess(){
// Give the user their IAP back! Likely all you'll need to
// do is call the same function you call when a user
// sucessfully completes their purchase. In this case, removeAdsSuccess()
removeAdsSuccess()
}
// This will be called by IAPManager
// when the IAP failed
class func removeAdsFailure(){
// Send the user a message explaining that the IAP
// failed for some reason, and to try again later
}
// This will be called by IAPManager
// when the IAP gets deferred.
class func removeAdsDeferred(){
// Send the user a message explaining that the IAP
// was deferred, and pending an external action, like
// Ask to Buy.
}
সব কিছু একসাথে রাখলে আমরা এরকম কিছু পাই:
