协议,税务和银行业务以及新建app就不说明了。网上有很多详细的内容。

主要还是看代码吧：

新建一个StoreObserver.h、StoreObserver.m文件

//.h

#import <Foundation/Foundation.h>

#import <StoreKit/StoreKit.h>

#import <StoreKit/SKPaymentTransaction.h>

#import <UIKit/UIKit.h>

#define kProductsLoadedNotification @"ProductsLoaded"

#define kProductPurchaseFailedNotification @"ProductPurchaseFailed"

#define kProductPurchasedNotification @"ProductPurchased"

#define kProductPurchasedButtonOpenNotification @"ButtonOpen"

@interface StoreObserver : NSObject <SKPaymentTransactionObserver, SKProductsRequestDelegate>{

int buyType;

}

-(void)Create;

-(void)Destroy;

-(void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions;

-(void)PurchasedTransaction: (SKPaymentTransaction *)transaction;

-(void)completeTransaction: (SKPaymentTransaction *)transaction;

-(void)failedTransaction: (SKPaymentTransaction *)transaction;

-(void)paymentQueueRestoreCompletedTransactionsFinished: (SKPaymentTransaction *)transaction;

-(void)paymentQueue:(SKPaymentQueue *) paymentQueue restoreCompletedTransactionsFailedWithError:(NSError *)error;

-(void)Buy:(int)type;

-(bool)CanMakePay;

-(void)RequestProductData;

-(void)restoreTransaction: (SKPaymentTransaction *)transaction;

-(void)addProductToPaymentQueue:(int)ProductType;

+(StoreObserver *)shareStoreObserver;
