我已使用以下代码进行应用内购买。
- (void)viewDidLoad {
if ([SKPaymentQueue canMakePayments]) {
NSLog(@"Can Buy Product");
SKProductsRequest *productRequest=[[SKProductsRequest alloc]initWithProductIdentifiers:[NSSet setWithObject:@"com.mycompany.myproduct.productpack"]];
productRequest.delegate=self;
[productRequest start];
}
else {
NSLog(@"Product Can't be purchased");
}
}
-(IBAction)purchasePack1 {
SKPayment *payment=[SKPayment paymentWithProductIdentifier:@"com.mycompany.myproduct.productpack"];
[[SKPaymentQueue defaultQueue] addTransactionObserver:self];
[[SKPaymentQueue defaultQueue] addPayment:payment];
}
-(void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response {
validProduct=nil;
int count=[response.products count];
if (count>0) {
NSLog(@"Product Avail");
validProduct=[response.products objectAtIndex:0];
}
else {
NSLog(@"No Product avail");
[purchaseBtn setHidden:TRUE];
}
}
-(void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions {
for (SKPaymentTransaction *transaction in transactions) {
switch (transaction.transactionState) {
case SKPaymentTransactionStatePurchasing:
NSLog(@"Purchasing");
[activityIndicatorObj setHidden:FALSE];
[activityIndicatorObj startAnimating];
break;
case SKPaymentTransactionStatePurchased:
UIAlertView *alt=[[UIAlertView alloc]initWithTitle:@"Congrats" message:@"Thanks For Purchasing " delegate:self cancelButtonTitle:@"Dismiss" otherButtonTitles:nil];
[alt show];
[alt release];
NSLog(@"Purchased");
[activityIndicatorObj stopAnimating];
[activityIndicatorObj setHidden:TRUE];
[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
break;
case SKPaymentTransactionStateFailed:
if (transaction.error.code!=SKErrorPaymentCancelled) {
NSLog(@"Cancelled");
}
[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
UIAlertView *alt1=[[UIAlertView alloc]initWithTitle:@"Sorry" message:@"Some Error Encountered!" delegate:self cancelButtonTitle:@"Dismiss" otherButtonTitles:nil];
[alt1 show];
[alt1 release];
NSLog(@"Failed");
[activityIndicatorObj stopAnimating];
[activityIndicatorObj setHidden:TRUE];
break;
case SKPaymentTransactionStateRestored:
NSLog(@"Restored");
[activityIndicatorObj stopAnimating];
[activityIndicatorObj setHidden:TRUE];
[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
break;
default:
break;
}
}
}
当我点击购买按钮时，我收到一条警告消息“您已经购买了该产品但尚未下载，是否要下载？” 当我单击"is"时，我没有从 App 收到任何响应，而且我确定该产品尚未下载。谁能告诉我对这个问题的建议。提前致谢。
最佳答案
我没有看到 - (void)provideContent:(NSString *)productId 的任何实现 - 你错过了那部分吗？在任何情况下，当 transactionState 也变为 SKPaymentTransactionStatePurchased 时，您应该会收到通知。
您可能想看看 in-app 上的 Ray Wenderlich tut如果您还没有购买，它将帮助您设置一个应用程序内管理器类。我认为您已将应用程序内逻辑放在 View Controller 中 - 最好将该部分留在单独的类中。所以应用内管理器/助手 :-)
