IOS中的IAP參考教程

生成productID的步驟，參考這篇教程：http://mobile.51cto.com/iphone-389249.htm ，附加一篇關於cocos2dx在IOS上實現IAP的教程：http://www.tairan.com/archives/5515  ，後者生成productID的步驟思路較清晰容易理解，建議參考後者的步驟

給出的生成productID教程中的信息已經和如今的developer.apple.com中有些出入，請靈活變通運用，生成可用的productID

如下僅僅是參考的實現代碼，若有須要請酌情變動相應的內容

.h文件

導入storekit.framework

文件中很簡單，創建一個簡單的繼承於NSObject的子類，只須要引入兩個協議

#import <Foundation/Foundation.h>

#import <StoreKit/StoreKit.h>

@interface IapDelegate : NSObject<SKProductsRequestDelegate, SKPaymentTransactionObserver,UIAlertViewDelegate>

- (void)methodOfShopBtn;

@end

-------------------------------------------------------------------------------------------------------------分隔線

.m文件

‍這個文件中僅僅是實現兩個協議的一些方法，我添加觸發方法，，，，若是測試僅僅是測試，學習，能夠直接把getProductInfo這個方法中紅色標出的productID改爲讀者所生成的productID應該就能夠直接運行‍

#import "IapDelegate.h"

#include "cocos2d.h"

@implementation IapDelegate

#pragma mark - 方法

- (void)methodOfShopBtn（整個IAP的進口，觸發方法）

{

    

    if ([SKPaymentQueue canMakePayments]) {

        UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"提示" message:@"當即開啓提示功能" delegate:self cancelButtonTitle:@"取消" otherButtonTitles:@"購買", nil];

        [alertView show];

    }

    else

    {

        NSLog(@"用戶禁止輸入");

    }

}

- (void)getProductInfo

{

    //IOS中原生storekit調用代碼

    [[SKPaymentQueue defaultQueue] addTransactionObserver:self];

        NSSet *set = [NSSet setWithArray:@[@"你的productID"]];

        SKProductsRequest *request = [[SKProductsRequest alloc] initWithProductIdentifiers:set];

        request.delegate = self;

        [request start];

}

- (void)completeTransaction:(SKPaymentTransaction *)transaction

{

    NSString *productIdentifier = transaction.payment.productIdentifier;

    NSString *receipt = [transaction.transactionReceipt base64Encoding];

    

    if ([productIdentifier length] > 0) {

        //

    }

    [[SKPaymentQueue defaultQueue] finishTransaction:transaction];

}

- (void)failedTransaction:(SKPaymentTransaction *)transaction

{

    if (transaction.error.code != SKErrorPaymentCancelled) {

        NSLog(@"購買失敗");

    }

    else{

        NSLog(@"用戶取消交易");

    }

    [[SKPaymentQueue defaultQueue] finishTransaction:transaction];

}

- (void)restoreTransaction:(SKPaymentTransaction *)transaction

{

    [[SKPaymentQueue defaultQueue] finishTransaction:transaction];

}

#pragma mark - SKProductsRequestDelegate方法

-(void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response

{

    NSArray *myProduct = response.products;

    if (myProduct.count == 0) {

        NSLog(@"沒法獲取產品信息，購買失效");

        return ;

    }

    SKPayment *payment = [SKPayment paymentWithProduct:myProduct[0]];

    NSLog(@"測試:%@", payment.productIdentifier);

    [[SKPaymentQueue defaultQueue] addPayment:payment];

}

#pragma mark - skpaymentObserver方法

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

{

                NSLog(@"transactionIdentifier = %@", transaction.transactionIdentifier);

                cocos2d::UserDefault *userDefaults = cocos2d::UserDefault::getInstance();

                userDefaults -> setBoolForKey("ShowSolution", YES);

                [self completeTransaction:transaction];

                break;

                break;

            default:

#pragma mark - uialertview代理方法

-(void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex

{

    NSLog(@"按鈕%d",buttonIndex);

    if (buttonIndex == 1) {

        [self getProductInfo];

    }

}
