希望这是足以帮助我解决问题的信息。
我通过提供给我的模板化源代码设置In App Purchases。在我的MKStoreManager.m文件中，我为我的应用内购买设置了featureID（例如：static NSString *featureAId = @"com.logannat.myfirstgameTier1";）
点击游戏中的实际按钮时，方法
- (void) buyFeature:(SKProduct*) product
{
if ([SKPaymentQueue canMakePayments])
{
SKPayment *payment = [SKPayment paymentWithProduct:product];
[[SKPaymentQueue defaultQueue] addPayment:payment];
}
}
最终被召唤。我设置了一个断点，发现错误位于该代码的最后一行。
以断点状态显示的变量是：
我似乎无法弄清楚这里的问题是什么。非常感谢任何帮助，谢谢。

我没有swift现在所以我给你Xcode代码请相应地转换语法并不那么困难。 所以这里是购买的应用程序的完整生命周期。 在您的头文件中调用这些代理并设置bool以检查您购买的状态
像那样#import <UIKit/UIKit.h>
BOOL arefavorite_access;
BOOL areAdsRemoved;
@interface ViewController : UIViewController<SKProductsRequestDelegate, SKPaymentTransactionObserver>{
}
- (IBAction)purchase;
- (IBAction)restore;
- (IBAction)tapsRemoveAds:(id)sender;
@end
你需要在你的按钮选择器上触摸这个tapsRemoveAds方法，它将开始工作。
- (IBAction)tapsRemoveAds:(id)sender{
UIButton*btn=(UIButton*)sender;
NSString *featureAId = @"com.logannat.myfirstgameTier1";
NSLog(@"User requests to remove ads");
if([SKPaymentQueue canMakePayments]){
NSLog(@"User can make payments");
SKProductsRequest *productsRequest;
if (btn.tag==1) {
productsRequest = [[SKProductsRequest alloc] initWithProductIdentifiers:[NSSet setWithObject: featureAId]];
_protype= featureAId;
}
productsRequest.delegate = self;
[productsRequest start];
}
else{
NSLog(@"User cannot make payments due to parental controls");
//this is called the user cannot make payments, most likely due to parental controls
}
}
产品请求方法
- (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 Available!");
[self purchase:validProduct];
}
else if(!validProduct){
NSLog(@"No products available");
//this is called if your product id is not valid, this shouldn't be called unless that happens.
}
}
- (IBAction)purchase:(SKProduct *)product{
SKPayment *payment = [SKPayment paymentWithProduct:product];
[[SKPaymentQueue defaultQueue] addTransactionObserver:self];
[[SKPaymentQueue defaultQueue] addPayment:payment];
}
- (IBAction) restore{
[[SKPaymentQueue defaultQueue] addTransactionObserver:self];
[[SKPaymentQueue defaultQueue] restoreCompletedTransactions];
}
- (void)paymentQueueRestoreCompletedTransactionsFinished:(SKPaymentQueue *)queue {
NSLog(@"%@",queue );
NSLog(@"Restored Transactions are once again in Queue for purchasing %@",[queue transactions]);
NSMutableArray *purchasedItemIDs = [[NSMutableArray alloc] init];
NSLog(@"received restored transactions: %i", queue.transactions.count);
for (SKPaymentTransaction *transaction in queue.transactions) {
NSString *productID = transaction.payment.productIdentifier;
[purchasedItemIDs addObject:productID];
NSLog (@"product id is %@" , productID);
_protype=productID;
[self doRemoveAds];
// here put an if/then statement to write files based on previously purchased items
// example if ([productID isEqualToString: @"youruniqueproductidentifier]){write files} else { nslog sorry}
}
if(queue.transactions.count==0){
[Utilities showOKAlertWithTitle:@"Restore purchase" message:@"you have no product available for restoration"];
}
}
- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions{
for(SKPaymentTransaction *transaction in transactions){
switch(transaction.transactionState){
case SKPaymentTransactionStatePurchasing: NSLog(@"Transaction state -> Purchasing");
//called when the user is in the process of purchasing, do not add any of your own code here.
break;
case SKPaymentTransactionStatePurchased:
//this is called when the user has successfully purchased the package (Cha-Ching!)
[self doRemoveAds]; //you can add your code for what you want to happen when the user buys the purchase here, for this tutorial we use removing ads
[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
NSLog(@"Transaction state -> Purchased");
[[SKPaymentQueue defaultQueue] removeTransactionObserver:self];
break;
case SKPaymentTransactionStateRestored:
NSLog(@"Transaction state -> Restored");
_protype=transaction.payment.productIdentifier;
[self doRemoveAds];
//add the same code as you did from SKPaymentTransactionStatePurchased here
[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
[[SKPaymentQueue defaultQueue] removeTransactionObserver:self];
break;
case SKPaymentTransactionStateFailed:
//called when the transaction does not finish
if(transaction.error.code == SKErrorPaymentCancelled){
NSLog(@"Transaction state -> Cancelled");
//the user cancelled the payment ;(
}
[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
[[SKPaymentQueue defaultQueue] removeTransactionObserver:self];
break;
}
}
}
- (void)doRemoveAds{
// // [self.bannerView setAlpha:0];
NSString *featureAId = @"com.logannat.myfirstgameTier1";
NSString *featureAIdnumber2 = @"com.logannat.myfirstgameTier2";
if([_protype isEqualToString:featureAId]){
arefavorite_access = YES;
[[NSUserDefaults standardUserDefaults] setBool:arefavorite_access forKey:frareFavoriteRemoved];
[[NSUserDefaults standardUserDefaults] synchronize];

else if([_protype isEqualToString: featureAIdnumber2]){
areAdsRemoved = YES;
[[NSUserDefaults standardUserDefaults] setBool:areAdsRemoved forKey:frareAdsRemoved];

// [self showpopUp:self];
