=============第四部分主要實現代碼==========

首先導入StoreKit.framework庫
.h文件

#import <StoreKit/StoreKit.h>
enum{ 
    IAP0p20=20, 
    IAP1p100, 
    IAP4p600,     
    IAP9p1000,     
    IAP24p6000, 
}buyCoinsTag;//代理

@interface RechargeVC : UIViewController <SKPaymentTransactionObserver,SKProductsRequestDelegate >{
    int buyType; 
}  
- (void) requestProUpgradeProductData;  
-(void)RequestProductData;  
-(void)buy:(int)type;  
- (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) restoreTransaction: (SKPaymentTransaction *)transaction;  
-(void)provideContent:(NSString *)product;  
-(void)recordTransaction:(NSString *)product;
@end
