IAP開發需要的注意點

在沙箱環境測試

Store Kit在模擬器上無法執行，需要使用真機測試

sanbox和app store內容一致，只是不執行真實的支付動作

在測試的iphone上面退出itunes賬戶

不能在測試的iphone手機上登入測試賬戶登入

在程式中購買商品後，storekit會提示你去驗證交易，這個時候你需要用測試賬戶登入，並批覆支付

登入itunes connect去使用者和職能中新增沙盒技術測試賬戶

IAP開發在客戶端和服務端需要做的事情

在客戶端 檢測是否可以進行支付-》獲取商品資訊-》建立一個支付物件-》為支付佇列註冊一個觀察者物件-》交易結果-》提示給使用者

服務端將接收到的資料以base64編碼的方式建立JSON併發送給APPSore進行驗證

程式碼如下

#import <StoreKit/StoreKit.h>

@interface ViewController ()<SKProductsRequestDelegate,SKStoreProductViewControllerDelegate>


@property (nonatomic,strong)SKProduct *product;

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
}


- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

- (IBAction)startPayAction:(UIButton *)sender {
    
    //判斷當前裝置是否允許支付
    if(![SKPaymentQueue canMakePayments]) {
    
        return;
    }
    
    NSSet *set =[NSSet setWithObjects:@"", nil];
    SKProductsRequest *req=[[SKProductsRequest alloc] initWithProductIdentifiers:set];
    req.delegate=self;
    
    [req start];
}

#pragma mark SKStoreProductViewControllerDelegate
- (void)productViewControllerDidFinish:(SKStoreProductViewController *)viewController
{
    
}

{
//
    for (SKProduct *product in response.products) {
        
        self.product = product;
    }
    
    //將獲取到的產品資訊，加入到支付佇列
    
    SKPayment *payment  =[SKPayment paymentWithProduct:  self.product];
    
    [[SKPaymentQueue defaultQueue] addTransactionObserver:self];
    
    [[SKPaymentQueue defaultQueue] addPayment:payment];
    
}
- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray<SKPaymentTransaction *> *)transactions
{
    
    
    for (SKPaymentTransaction *transaction in transactions) {
        
        switch (transaction.transactionState) {
            case SKPaymentTransactionStatePurchasing:
                
                break;
            case SKPaymentTransactionStatePurchased:
                {
                    [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
                }
                break;
            case SKPaymentTransactionStateFailed:
                
                break;
            case SKPaymentTransactionStateRestored:
                
                break;
            default:

        }
    }
