齐桓公ios内购对接之源码篇--详细

本文主要是介绍齐桓公ios内购对接之源码篇--详细，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

在开篇之前首先提供一个调试工具，对ios开发人员来说微不足道，但对新手来说可谓如获至宝，mac工具，图标如下控制台

打开之后

有时候我们的xcode并不能抛出这些错误，只有通过控制台连接手机才可才看所有相关的信息日志，报错信息等

对接ios内购

前提条件：ios内购有一个库storeKit.framework,这个库封装好了ios内购相关的代码，我们只需要调用即可，一般情况下工程会自动添加这个库，同时我们要保证自己的app开启了内购，在开发者平台的appid里可以开启，现在都是默认开启了

那么第一步我们要先了解ios内购的流程，看过很多教程，流程图都一大堆，但桓公只做最简单的流水线流程

通过productid向苹果服务器请求商品 --- 拿到之后即掉支付进入支付队列 --- 支付完成后回调支付状态 ---- 支付完成之后会有一个receipt字段是一个加密字符串 --- 把这个receipt给到自己的服务端 ---- 自己的服务端对receipt进行解码并向苹果服务器验证 ---- 验证成功通知客户端发放奖励

基本流程如此，就相当于去书店(appstore)买书 --- 买黄帝内经素问(productid) --- 书店查有没有(请求商品) ---- 有素问(查询成功) ---- 支付成功店里银行账户到账了(苹果支付了) 给了一个发票 ---- 拿着发票去服务人员那领书素问 (向服务器请求receipt 并验证成功发放奖励) --- 完成

流程清楚了，接下来就好办了，需要一步步来，不要越步，做任何事只要你知道了流程就如同你预知了未来一样，只要按照步骤流程走，预言就一定会实现

此以laya为例，由于laya生产的ios项目是需要H5这边来掉的，虽然laya自带了一个conchMarket，但这里不用他的，因为有坑，这里会自己封装JSBridge，JSBridge是客户端与H5的通信桥梁，皆以字符串的形式完成掉用和回调

在jsbridge里添加方法

+(void)callBackToJs:(NSString*)strFunc param:(NSString*)param
{
    [[conchRuntime GetIOSConchRuntime] callbackToJSWithClassName:NSStringFromClass(self.class) methodName:strFunc ret:param];
}
+(void)callRunJs:(NSString*)strCode
{
    [[conchRuntime GetIOSConchRuntime] runJS:strCode];
}

callBackToJs是回调js的方法，其中的methodName既是js端掉用的方法名，注意这里的回调是异步的

向jsbridge添加内购及回调的方法

//苹果内购
+(void)doIosZF:(NSString*)jsonParam
{
    NSData* data = [jsonParam dataUsingEncoding:NSUTF8StringEncoding];
    NSDictionary* json = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:nil];
    if (json == nil) return [self iosPayCallBack:-1 reason:@"订单信息错误！" receipt:@"" orderid:@""];
    NSString *productId = json[@"productID"];
    NSString *orderid = json[@"orderID"];
    if (productId == nil || orderid == nil) return [self iosPayCallBack:-1 reason:@"订单信息缺失！" receipt:@"" orderid:@""];
    [[IAPManager getInstance] buy:productId orderid:orderid];
}

+(void)iosPayCallBack:(NSInteger)p_iRet reason:(NSString *)p_pReason receipt:(NSString *)p_pReceipt orderid:(NSString *)p_pOrderid
{
    NSString* pJsonString = @"{  \"act\" : \"0\", \"tip\" : \"error\", \"order\" : \"error\", \"receipt\" : \"error\"}";
    NSString* sNum = [NSString stringWithFormat:@"%ld",p_iRet];
    NSDictionary* pDictionary = [NSDictionary dictionaryWithObjectsAndKeys:sNum,@"act",p_pReason?p_pReason:@"error",@"tip",p_pOrderid?p_pOrderid:@"error",@"order",p_pReceipt?p_pReceipt:@"error",@"receipt",nil];
    NSError* pError = nil;
    NSData* pJsonData = [NSJSONSerialization dataWithJSONObject:pDictionary options:NSJSONWritingPrettyPrinted error:&pError];
    if( !pError )
    {
        pJsonString = [[NSString alloc] initWithData:pJsonData encoding:NSUTF8StringEncoding];
    }
    [self callBackToJs:@"doIosZF:" param:pJsonString];
}

js端则如下

private static doIosZF(productId, cb_completed){
        let func = (res)=>{
            let code = res["act"];
            log("---ios iap back act:", code, "data:", res);
            if (code == 0) {
                let param =  {
                    token:userData.token,
                    uid:userData.uid,
                    receipt:res.receipt,
                    product_id:productId
                };
                WebAPI.post('shop/applePay',param,(obj)=>{
                    let son = JSON.parse(obj);
                    dealPayEnd(son.code, cb_completed);
                })
            }
            else{
                app.showAlert('支付失败');
            }
        }
        let params = {
            "orderID":`OrderID_${new Date().getTime()}_${productId}`,
            "productID":this.marketCommedities[productId],
        }
        let json = JSON.stringify(params);
        log('----reqest buy ios ',json)
        Native.callWithBack(func,'doIosZF',json);
    }

Native.ts 初始化jsbridge及调用如下

public static initBridge() {
        if (this.isAndroidApp()) {
            this.bridge = Laya.PlatformClass.createClass("app.JSBridge");
        }
        if (this.isIOSApp()) {
            this.bridge = Laya.PlatformClass.createClass("JSBridge")
        }
    }

public static callWithBack(callback: Function, methodName: string, ...args: any[]): void {
        if (!this.bridge) { this.initBridge(); }
        if (this.isIOSApp() && args.length == 1) {
            if (args.length == 1) {
                methodName += ":";
            } else {
                log("ios call native error!!!");
            }
        }
        this.bridge.callWithBack(function (msg) { callback(JsonParseSafe(msg)); }, methodName, ...args);
    }

注意：

1、ios的方法要加：这个字符串， oc端回调的时候亦是如此，如下

2、这里的receipt的校验是在js端，非oc端，oc端仅做内购功能及回调

OK 这里我们H5端js调用了oc端的 doIosZF 方法，接下来就是oc端去实现

IAPManager的逻辑

桓公本对此一窍不通，如何对接？我们看到JSBridge里的doIosZF方法里掉了IAPManager的buy方法，并传了productid和orderid两个参数，那么我们来看下IAPManager的buy方法

-(void)buy:(NSString*)productId orderid:(NSString*) orderid
{
    bool canBuy = [SKPaymentQueue canMakePayments];
    
    if (canBuy) {
        NSLog(@"允许程序内付费购买");
        //直接购买
        //SKPayment *payment = [SKPayment paymentWithProductIdentifier:productId];
        
        SKMutablePayment *payment = [SKMutablePayment paymentWithProductIdentifier:productId];
        payment.applicationUsername = orderid;
        
        NSLog(@"---------发送购买请求------------");
        [[SKPaymentQueue defaultQueue] addPayment:payment];
    }
    else
    {
        [self.delegate onCallBack:-1 reason:@"You can‘t purchase in app store（没允许应用程序内购买）" retry:false receipt:@"" orderid:@""];
    }
}

这里自己去研究，oc代码：函数的执行皆是[]，其实也很容易懂

IAPManager首先要初始化，初始化方法，这个初始化方法其实在MarketAppStore里初始化了

- (id)initWithGameID:(NSString*)gameID andDelegate:(id<JCIapProcessCtrlDelegate>)delegate{
    if ((self = [super init])) {
        NSAssert(gameID != nil,@"[IAP] gameID can not be nil");
        NSAssert(gameID.length <= __MAX_GAME_ID_SIZE,@"gameID is too long");
        self.gameAppID = [NSString stringWithString:gameID];
        NSAssert(delegate != nil, @"[IAP] delegate can not be nil");
        self.delegate = delegate;
        self.strPlateform = [NSString stringWithFormat:@"%@,%@,%@", [[UIDevice currentDevice] model], [[UIDevice currentDevice] systemName],[[UIDevice currentDevice] systemVersion]];
        NSLog(@"[IAP]plateform info: %@\n", self.strPlateform);
        [[SKPaymentQueue defaultQueue] addTransactionObserver:self];
    }
    return self;
}

注意 这里不使用MarketAppStore作为回调，而是使用另外封装的SDKManager作为回调对象代理，因此这里初始化的代码就变成了

-(void)	LP_Init
{
    SDKManager *sdkmgr = [SDKManager getInstance];
    [[IAPManager getInstance] initWithGameID:[conchConfig GetInstance]->m_sGameID andDelegate:sdkmgr];
}

SDKManager.mm类里添加这个回调，这里有个retry不用管，完成后他会去掉JSBridge的iosPayCallBack,这里就会回调给js的doIosZF的回调方法了，同时把参数也传过去了，注意传的是json字符串，注意解析

- (void)onCallBack:(NSInteger)p_iRet reason:(NSString *)p_pReason retry:(Boolean)bRetry receipt:(NSString *)p_pReceipt orderid:(NSString *)p_pOrderid
{
    if(bRetry)
    {
        NSString* sJs = [NSString stringWithFormat:@"if(window.Laya)window.Laya.Browser.window.onRetryIosZF(%ld,'%@','%@','%@');",(long)p_iRet,p_pReason,p_pReceipt,p_pOrderid];
        [JSBridge callRunJs:[NSString stringWithCString:[sJs UTF8String] encoding:NSUTF8StringEncoding]];
    }
    else
    {
        [JSBridge iosPayCallBack:p_iRet reason:(p_pReason?p_pReason:@"") receipt:(p_pReceipt?p_pReceipt:@"") orderid:(p_pOrderid?p_pOrderid:@"")];
    }
}

然后我们看IAPManager里内购完成的回调方法

- (void) completeTransaction: (SKPaymentTransaction *)transaction retry:(Boolean)bRetry
{
    NSLog(@"-----completeTransaction--------");
    NSString* pszBase64 = [transaction.transactionReceipt base64Encoding];
    [self.delegate onCallBack:0 reason:@"购买成功！" retry:bRetry receipt:pszBase64 orderid:transaction.payment.applicationUsername];
}

- (void) failedTransaction: (SKPaymentTransaction *)transaction retry:(Boolean)bRetry
{
    NSLog(@"失败,%ld,%@",(long)transaction.error.code,[transaction.error localizedDescription]);
    
    [[SKPaymentQueue defaultQueue] finishTransaction: transaction];
    //用户取消
    if (transaction.error.code == SKErrorPaymentCancelled)
        [self.delegate onCallBack:-1 reason:@"您取消支付！" retry:bRetry receipt:@"" orderid:@""];
    else
        [self.delegate onCallBack:-1 reason:[transaction.error localizedDescription] retry:bRetry receipt:@"" orderid:@""];
}

都会有这个代理方法 self.delegate onCallBack: 这个就会回调到SDKManager的onCallBack方法

注意：productid必须是与app内购里配置的id一致，否则找不到

而且重中之重的是：productid 一定是字符串，绝不可传number型，否则你会看到请求没任何反应，也没报错，这时候就要用到开头说的控制台了，这个让我查了足足三天之多，可见阴阳变化莫测，虽极微之道，亦可倾天盖地也。

这里奉上IAPManger 源码，望世间无如吾之愚人

}

        NSAssert(gameID.length <= __MAX_GAME_ID_SIZE,@"gameID is too long");
        self.gameAppID = [NSString stringWithString:gameID];
