應用程序內購買是應用程序用於購買額外內容或升級功能。
1.在 iTunes 連接中請確保擁有一個唯一的 App ID(unique App ID ),當創建捆綁的ID( bundle ID)應用程序更新時,代碼會以相應的配置文件簽名在Xcode上
2.創建新的應用程序和更新應用程序信息。你可以知道更多有關的,在蘋果的 添加新的應用程序 文檔中
3.在應用程序頁的管理應用程序( Manage In-App Purchase)中,為app內付費添加新產品
4.確保設置的應用程序為的銀行詳細。需要將其設置為在應用程序內購買(In-App purchase)。此外在 iTunes 中使用管理用戶(Manage Users)選項,創建一個測試用戶帳戶連接您的應用程序的頁。
5.下一步是與處理代碼和為我們在應用程序內購買創建有關的 UI。
6.創建一個單一的視圖應用程序,並在 iTunes 中指定的標識符連接輸入捆綁標識符
7.更新ViewController.xib ,如下所示
8.為三個標簽創建IBOutlets,且將按鈕分別命名為 productTitleLabel、 productDescriptionLabel、 productPriceLabel 和 purchaseButton
9.選擇項目文件,然後選擇目標,然後添加StoreKit.framework
10.更新ViewController.h ,如下所示
#import <UIKit/UIKit.h> #import <StoreKit/StoreKit.h> @interface ViewController : UIViewController< SKProductsRequestDelegate,SKPaymentTransactionObserver> { SKProductsRequest *productsRequest; NSArray *validProducts; UIActivityIndicatorView *activityIndicatorView; IBOutlet UILabel *productTitleLabel; IBOutlet UILabel *productDescriptionLabel; IBOutlet UILabel *productPriceLabel; IBOutlet UIButton *purchaseButton; } - (void)fetchAvailableProducts; - (BOOL)canMakePurchases; - (void)purchaseMyProduct:(SKProduct*)product; - (IBAction)purchase:(id)sender; @end
11.更新ViewController.m ,如下所示
#import "ViewController.h" #define kTutorialPointProductID @"com.tutorialPoints.testApp.testProduct" @interface ViewController () @end @implementation ViewController - (void)viewDidLoad { [super viewDidLoad]; // Adding activity indicator activityIndicatorView = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge]; activityIndicatorView.center = self.view.center; [activityIndicatorView hidesWhenStopped]; [self.view addSubview:activityIndicatorView]; [activityIndicatorView startAnimating]; //Hide purchase button initially purchaseButton.hidden = YES; [self fetchAvailableProducts]; } - (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; // Dispose of any resources that can be recreated. } -(void)fetchAvailableProducts{ NSSet *productIdentifiers = [NSSet setWithObjects:kTutorialPointProductID,nil]; productsRequest = [[SKProductsRequest alloc] initWithProductIdentifiers:productIdentifiers]; productsRequest.delegate = self; [productsRequest start]; } - (BOOL)canMakePurchases { return [SKPaymentQueue canMakePayments]; } - (void)purchaseMyProduct:(SKProduct*)product{ if ([self canMakePurchases]) { SKPayment *payment = [SKPayment paymentWithProduct:product]; [[SKPaymentQueue defaultQueue] addTransactionObserver:self]; [[SKPaymentQueue defaultQueue] addPayment:payment]; } else{ UIAlertView *alertView = [[UIAlertView alloc]initWithTitle: @"Purchases are disabled in your device" message:nil delegate: self cancelButtonTitle:@"Ok" otherButtonTitles: nil]; [alertView show]; } } -(IBAction)purchase:(id)sender{ [self purchaseMyProduct:[validProducts objectAtIndex:0]]; purchaseButton.enabled = NO; } #pragma mark StoreKit Delegate -(void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions { for (SKPaymentTransaction *transaction in transactions) { switch (transaction.transactionState) { case SKPaymentTransactionStatePurchasing: NSLog(@"Purchasing"); break; case SKPaymentTransactionStatePurchased: if ([transaction.payment.productIdentifier isEqualToString:kTutorialPointProductID]) { NSLog(@"Purchased "); UIAlertView *alertView = [[UIAlertView alloc]initWithTitle: @"Purchase is completed succesfully" message:nil delegate: self cancelButtonTitle:@"Ok" otherButtonTitles: nil]; [alertView show]; } [[SKPaymentQueue defaultQueue] finishTransaction:transaction]; break; case SKPaymentTransactionStateRestored: NSLog(@"Restored "); [[SKPaymentQueue defaultQueue] finishTransaction:transaction]; break; case SKPaymentTransactionStateFailed: NSLog(@"Purchase failed "); break; default: break; } } } -(void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response { SKProduct *validProduct = nil; int count = [response.products count]; if (count>0) { validProducts = response.products; validProduct = [response.products objectAtIndex:0]; if ([validProduct.productIdentifier isEqualToString:kTutorialPointProductID]) { [productTitleLabel setText:[NSString stringWithFormat: @"Product Title: %@",validProduct.localizedTitle]]; [productDescriptionLabel setText:[NSString stringWithFormat: @"Product Desc: %@",validProduct.localizedDescription]]; [productPriceLabel setText:[NSString stringWithFormat: @"Product Price: %@",validProduct.price]]; } } else { UIAlertView *tmp = [[UIAlertView alloc] initWithTitle:@"Not Available" message:@"No products to purchase" delegate:self cancelButtonTitle:nil otherButtonTitles:@"Ok", nil]; [tmp show]; } [activityIndicatorView stopAnimating]; purchaseButton.hidden = NO; } @end
注意: 需要修改你創建In-App Pur(應用內購買)的 kTutorialPointProductID 。通過修改fetchAvailableProducts產品標識符的 NSSet, 你可以添加多個產品。
運行該應用程序,輸出結果如下
確保已經中登錄。單擊購買選擇現有的Apple ID。輸入有效的測試帳戶的用戶名和密碼。幾秒鐘後,顯示下面的信息
一旦產品成功購買,將獲得以下信息。可以在顯示此信息的地方,更新應用功能相關的代碼
