苹果内购的基本教程

OC苹果内购

“大家都知道支付宝，微信的继承与用法，但是大家忘了苹果的自身的支付功能，我也是最近项目因为内购一直被拒，所以，研究了一下内购，好了，废话不多说，直接上干货”

封装

首先遵守苹果内购的协议

 SKPaymentTransactionObserver,SKProductsRequestDelegate

实现单例模式

+ (instancetype)shareSIAPManager{
    static STRIAPManager *IAPManager = nil;
    static dispatch_once_t onceToken;
    dispatch_once(&onceToken,^{
        IAPManager = [[STRIAPManager alloc] init];
    });
    return IAPManager;
}

购买监听

 [[SKPaymentQueue defaultQueue] addTransactionObserver:self]

实现开始购买服务

#pragma mark - 🚪public
- (void)startPurchWithID:(NSString *)purchID completeHandle:(IAPCompletionHandle)handle{
    if (purchID) {
        if ([SKPaymentQueue canMakePayments]) {
            // 开始购买服务
            _purchID = purchID;
            _handle = handle;
            NSSet *nsset = [NSSet setWithArray:@[purchID]];
            request = [[SKProductsRequest alloc] initWithProductIdentifiers:nsset];
            request.delegate = self;
            [request start];
        }else{
            [self handleActionWithType:SIAPPurchNotArrow data:nil];
        }
    }
}

购买结果回调

#pragma mark - 🔒private
- (void)handleActionWithType:(SIAPPurchType)type data:(NSData *)data{
    switch (type) {
        case SIAPPurchSuccess:
            NSLog(@"购买成功");
            break;
        case SIAPPurchFailed:
            NSLog(@"购买失败");
            break;
        case SIAPPurchCancle:
            NSLog(@"用户取消购买");
            break;
        case SIAPPurchVerFailed:
            NSLog(@"订单校验失败");
            break;
        case SIAPPurchVerSuccess:
            NSLog(@"订单校验成功");
            break;
        case SIAPPurchNotArrow:
            NSLog(@"不允许程序内付费");
            break;
        default:
            break;
    }
    if(_handle){
        _handle(type,data);
    }
}

代理方法划重点了 --------

#pragma mark - 🍐delegate
// 交易结束
- (void)completeTransaction:(SKPaymentTransaction *)transaction{
    NSLog(@"交易结束");
    NSURL *receiptUrl = [[NSBundle mainBundle] appStoreReceiptURL];
    NSData *receiptData = [NSData dataWithContentsOfURL:receiptUrl];
    NSString * transactionReceiptString = [receiptData base64EncodedStringWithOptions:0];
//    Save(transactionReceiptString, @"JY");
    [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
    _transaction = transaction;
    [self handleActionWithType:SIAPPurchSuccess data:receiptData];
    
}


- (void)End {
    if (_transaction) {
         [[SKPaymentQueue defaultQueue] finishTransaction:_transaction];
    }
}


// 交易失败
- (void)failedTransaction:(SKPaymentTransaction *)transaction{
     [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
    if (transaction.error.code != SKErrorPaymentCancelled) {
        [self handleActionWithType:SIAPPurchFailed data:nil];
    }else{
        [self handleActionWithType:SIAPPurchCancle data:nil];
    }
   
}


#pragma mark - SKProductsRequestDelegate
- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response{
    NSArray *product = response.products;
    if([product count] <= 0){
        NSLog(@"--------------没有商品------------------");
        return;
    }
    
    SKProduct *p = nil;
    for(SKProduct *pro in product){
        if([pro.productIdentifier isEqualToString:_purchID]){
            p = pro;
            break;
        }
    }
    NSLog(@"productID:%@", response.invalidProductIdentifiers);
    NSLog(@"产品付费数量:%lu",(unsigned long)[product count]);
    NSLog(@"%@",[p description]);
    NSLog(@"%@",[p localizedTitle]);
    NSLog(@"%@",[p localizedDescription]);
    NSLog(@"%@",[p price]);
    NSLog(@"%@",[p productIdentifier]);
    NSLog(@"发送购买请求");
    SKPayment *payment = [SKPayment paymentWithProduct:p];
    [[SKPaymentQueue defaultQueue] addPayment:payment];
}

//请求失败
- (void)request:(SKRequest *)request didFailWithError:(NSError *)error{
    NSLog(@"------------------错误-----------------:%@", error);
    [self handleActionWithType:SIAPPurchTypeOvertime data:nil];
}

- (void)requestDidFinish:(SKRequest *)request{
    NSLog(@"------------反馈信息结束-----------------");

}

#pragma mark - SKPaymentTransactionObserver
- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray<SKPaymentTransaction *> *)transactions{
    for (SKPaymentTransaction *tran in transactions) {
        switch (tran.transactionState) {
            case SKPaymentTransactionStatePurchased:
                [self completeTransaction:tran];
                break;
            case SKPaymentTransactionStatePurchasing:
                NSLog(@"商品添加进列表");
                break;
            case SKPaymentTransactionStateRestored:
                NSLog(@"已经购买过商品");
                [[SKPaymentQueue defaultQueue] finishTransaction:tran];
                break;
            case SKPaymentTransactionStateFailed:
                [self failedTransaction:tran];
                break;
            default:
                break;
        }
    }
}

都加了注释，大家可以看看。

眼尖的小伙伴肯定发现了，没有删除监听方法，

- (void)dealloc {
    [self delect];
}

- (void)delect {
    [[SKPaymentQueue defaultQueue] removeTransactionObserver:self];
}

在viewController使用方法

#pragma mark - 这是内购吊起
- (void)payWithinBtn:(UIButton *)sender
{
    // 实例化内购类
    _apiMangager = [STRIAPManager shareSIAPManager];
    // 苹果后台配置的产品ID
    [_apiMangager startPurchWithID:payId completeHandle:^(SIAPPurchType type, NSData *data) {
        
        // 请求回调类型返回的数据
        NSString *rest = [data base64EncodedStringWithOptions:0];
        
        switch (type) {
            case SIAPPurchSuccess:
                NSLog(@"前段验证购买成功，请后台接口进行验证，加密后的数据为（%@）",rest);
                break;
            case SIAPPurchFailed:
                NSLog(@"购买失败");
                break;
            case SIAPPurchCancle:
                NSLog(@"取消购买");
                break;
            case SIAPPurchNotArrow:
                NSLog(@"此APP不允许内购");
                break;
            default:
                NSLog(@"绝对是苹果的锅,我也无能为力");
                break;
        }
        
    }];
    
    
}

*******************里面的payID 等一会会讲到，不要着急哦

很多小伙伴，肯定在想，怎么吊起内购呢，为啥写这些就可以吊起，别着急，现在就给小伙伴说一下 App Store 里面的设置

点击用户和访问，点击沙箱技术 -> 添加一下个号码

7259E26885C0D4479814EB9F596C385A.png

这里注意一点，地区，你是哪里的，就填哪里，别乱填，要不不会接受到

9452485E-722B-4B27-8D9C-00CDDDCD13A7.png

到这里基本，你就可以运行代码了
需要注意一点的是把自己的账号注销掉。 -----千万别登陆。
运行程序，会出现让你选取现有ID 还是其他ID，

 到这里基本就完成了， 可以放心大胆的购买， 都不花钱

我是菜鸟，其中有问题，记得评论在底下，我加上~
