我使用此代码来处理我的应用内购买：
#pragma mark StoreKit Delegate
-(void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions {
for (SKPaymentTransaction *transaction in transactions) {
switch (transaction.transactionState) {
case SKPaymentTransactionStatePurchasing:
{
// show wait view here
// statusLabel.text = @"Processing...";
}
break;
case SKPaymentTransactionStatePurchased:
{
[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
// remove wait view and unlock feature 2
// statusLabel.text = @"Done!";
UIAlertView *tmp = [[UIAlertView alloc]
initWithTitle:@"Complete"
message:@"You have unlocked Feature 2!"
delegate:self
cancelButtonTitle:nil
otherButtonTitles:@"Ok", nil];
[tmp show];
NSError *error = nil;
[SFHFKeychainUtils storeUsername:@"IAPStoreSave" andPassword:@"whatever" forServiceName:kStoredData updateExisting:YES error:&error];
// apply purchase action - hide lock overlay and
[self.lockImage removeFromSuperview];
// do other thing to enable the features
}
break;
case SKPaymentTransactionStateRestored:
{
[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
// remove wait view here
// statusLabel.text = @"";
}
break;
case SKPaymentTransactionStateFailed:
{
if (transaction.error.code != SKErrorPaymentCancelled) {
NSLog(@"Error payment cancelled");
}
[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
// remove wait view here
// statusLabel.text = @"Purchase Error!";
}
break;
default:
{
}
break;
}
}
}
-(void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response
{
// remove wait view here
// statusLabel.text = @"";
SKProduct *validProduct = nil;
int count = [response.products count];
if (count>0) {
validProduct = [response.products objectAtIndex:0];
SKPayment *payment = [SKPayment paymentWithProductIdentifier:@"com.app.ID"];
[[SKPaymentQueue defaultQueue] addTransactionObserver:self];
[[SKPaymentQueue defaultQueue] addPayment:payment];
} else {
UIAlertView *tmp = [[UIAlertView alloc]
initWithTitle:@"Not Available"
message:@"No products to purchase"
delegate:self
cancelButtonTitle:nil
otherButtonTitles:@"Ok", nil];
[tmp show];
}
}
-(void)requestDidFinish:(SKRequest *)request
{
}
-(void)request:(SKRequest *)request didFailWithError:(NSError *)error
{
NSLog(@"Failed to connect with error: %@", [error localizedDescription]);
}
并以这种方式启动它：
SKProductsRequest *request = [[SKProductsRequest alloc] initWithProductIdentifiers:[NSSet setWithObject:@"com.app.ID"]];
request.delegate = self;
[request start];
在我的iTunes Connect中，我使用我输入的产品ID设置了应用内，状态为“准备提交”，并且还显示：“您的第一个应用内购买必须使用新的应用程序版本。从“版本详细信息”页面的“应用内购买”部分中选择它们，然后单击“准备上传二进制文件”。当我开始请求时，警报 NO PRODUCT AVAILABLE 总是出现。我究竟做错了什么？？
