Question

我已经浏览了谷歌，几乎每一个关于添加应用内购买的stackoverflow问题，但它们似乎都不起作用。当我尝试在我的应用程序上进行购买时，一切正常，产品可用且一切，但有关购买的警报视图从未显示出来。以下是IAP的所有代码：

- (IBAction)tapsRemoveAdsButton{
NSLog(@"User taps remove ads button");
[self tapsRemoveAds];
}

- (void)tapsRemoveAds{
NSLog(@"User requests to remove ads");

if([SKPaymentQueue canMakePayments]){
    NSLog(@"User can make payments");

    SKProductsRequest *productsRequest = [[SKProductsRequest alloc] initWithProductIdentifiers:[NSSet setWithObject:kRemoveAdsProductIdentifier]];
    productsRequest.delegate = self;
    [productsRequest start];

}
else{
    NSLog(@"User cannot make payments due to parental controls");
}
}

- (IBAction)purchase{
SKProduct *removeAdsProductID = (SKProduct *)kRemoveAdsProductIdentifier;
SKPayment *payment = [SKPayment paymentWithProduct:(SKProduct *)kRemoveAdsProductIdentifier];
[[SKPaymentQueue defaultQueue] addTransactionObserver:self];
[[SKPaymentQueue defaultQueue] addPayment:payment];
}

- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response{
SKProduct *validProduct = nil;
int count = [response.products count];
if(count > 0){
    validProduct = [response.products objectAtIndex:0];
    NSLog(@"Products Avalable!");
    //[self sloganizeWord];
}
else if(!validProduct){
    NSLog(@"No products avalable");
}
}

- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions{
for(SKPaymentTransaction *transaction in transactions){
    switch (transaction.transactionState){
        case SKPaymentTransactionStatePurchasing: NSLog(@"Transaction state -> Purchasing");
            break;
        case SKPaymentTransactionStatePurchased: [self doRemoveAds];
            [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
             NSLog(@"Transaction state -> Purchased");
            break;
        case SKPaymentTransactionStateRestored:
             NSLog(@"Transaction state -> Restored");
            [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
            break;
        case SKPaymentTransactionStateFailed:
            if(transaction.error.code != SKErrorPaymentCancelled){
                NSLog(@"Transaction state -> Cancelled");
            }
            [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
            break;
        }
    }
}


- (void)doRemoveAds{
areAdsRemoved = YES;
[[NSUserDefaults standardUserDefaults] setBool:areAdsRemoved forKey:@"areAdsRemoved"];
[[NSUserDefaults standardUserDefaults] synchronize];
}

如果我正确地执行此操作，警报视图应显示在方法“paymentQueue”中，所有在我获得的控制台中：

user taps remove ads button
user requests to remove ads
user can make payments
products available!

直到paymentQueue方法，它还应该记录

transaction state -> purchasing

和其他人，我已经在iTunes Connect中设置了IAP，并且IAP的ID是正确的。（否则它不会记录产品可用）我在iOS7上使用非越狱设备并且我已经设置了所有配置文件（或者至少我认为，因为我已经使用广告将应用程序提交到应用商店）同样，我已经看了一些其他问题，但它们似乎都没有给我任何帮助。提前感谢任何帮助过的人和每个人：）

这不行：SKProduct *removeAdsProductID = (SKProduct *)kRemoveAdsProductIdentifier; - 您无法使用NSString*代替SKProduct*。

您应该使用validProduct中的- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response。

您只需要1个按钮/操作tapRemoveAds即可开始购买（不需要purchase IBAction）。

您需要掌握实际的SKProduct*：

- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response{
    SKProduct *validProduct = nil;
    int count = [response.products count];
    if(count > 0){
        validProduct = [response.products objectAtIndex:0];
        NSLog(@"Products Avalable!");

        // initiate the actual purchase
        [self purchase:validProduct];
    }
    else if(!validProduct){
        NSLog(@"No products avalable");
    }
}

-(void)purchase:(SKProduct *)product{
    SKPayment *payment = [SKPayment paymentWithProduct:product];
    [[SKPaymentQueue defaultQueue] addTransactionObserver:self];
    [[SKPaymentQueue defaultQueue] addPayment:payment];
}

更好的解决方案是在上一步中检索有效产品列表（例如：应用程序启动时），并且仅在upgrade对象可用时启用SKProduct *按钮

还有其他问题，例如不处理恢复（应该像处理SKPaymentTransactionStatePurchasing一样处理）。我建议您查看In-App Purchase Programming Guide以便更好地理解。
