本文只介绍苹果内购的代码实现步骤，如果需要知道具体流程可以参照http://www.jianshu.com/p/86ac7d3b593a
下面来介绍一下苹果内购的代码实现步骤。

第一步：导入StoreKit.framework库

1.点击主项目文件->Bulid Phases->Link Binary With Libraries

2.点击右下角的加号，选择添加StoreKit.framework库

3.这样我们就可以在我们的项目中成功导入了StoreKit.framework库

PS：如果项目中已有StoreKit.framework库，请勿重复添加，或者可以先删除原来的，再添加。

第二步：iospay.h

#import <Foundation/Foundation.h>
#import <StoreKit/StoreKit.h>

//对内购道具的枚举，可以自己取名
enum{
    IAP0p6,
    IAP1p18,
    IAP2p30,
    IAP3p98,
    IAP4p198,
    IAP5p328,
    IAP6p548,
    IAP7p648
}buyCoinsTag;

//代理
@interface iospay : NSObject <SKPaymentTransactionObserver,SKProductsRequestDelegate >
{
    int buyType;
}
//先初始化
-(id)initWithIosPay;

- (void) requestProUpgradeProductData;

-(void)RequestProductData;

//后调用这个函数
-(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

第三步：iospay.m

#import "iospay.h"

//填写自己在内购项目中创的商品单号，因涉及隐私，这里用******代替
#define ProductID_IAP0p6 @"******"//6
#define ProductID_IAP1p18 @"******"//18
#define ProductID_IAP2p30 @"******"//30
#define ProductID_IAP3p98 @"******"//98
#define ProductID_IAP4p198 @"******"//198
#define ProductID_IAP5p328 @"******"//328
#define ProductID_IAP6p548 @"******"//548
#define ProductID_IAP7p648 @"******"//648

@interface iospay ()

@end

第四步：在自己的支付接口处调用

如下图所示：

1.先初始化iospay。

2.直接调用buy函数，填写自己对应的waresid。
