我有一個iPhone應用程序在市場上有三個不同的應用程序購買它。問題是，當用戶購買功能時，他們通常會不止一次提示輸入密碼。這是正常的嗎？是蘋果公司還是我的代碼？在應用程序購買多次要求密碼
這裏是購買的一個示例：
InAppPurchaseManager *manager = [[InAppPurchaseManager alloc] init];
[manager loadStore];
if([manager canMakePurchases]){
[manager purchaseFeature:@"com.myfeature1"];
VehicleExpensesController *aViewController = [[VehicleExpensesController alloc]
initWithNibName:@"VehicleExpensesController" bundle:nil];
[self presentModalViewController:aViewController animated:YES];
[aViewController release], aViewController = nil;
}
，這裏是我的InAppPurchaseManager.m文件：
#import "InAppPurchaseManager.h"
@implementation InAppPurchaseManager
- (void)requestProUpgradeProductData
{
NSSet *productIdentifiers = [NSSet setWithObjects:@"com.myfeature1", @"com.myfeature2", @"com.myfeature3", nil ];
productsRequest = [[SKProductsRequest alloc] initWithProductIdentifiers:productIdentifiers];
productsRequest.delegate = self;
[productsRequest start];
// we will release the request object in the delegate callback
}
#pragma mark -
#pragma mark SKProductsRequestDelegate methods
- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response
{
NSArray *products = response.products;
proUpgradeProduct = [products count] == 1 ? [[products firstObject] retain] : nil;
if (proUpgradeProduct)
{
NSLog(@"Product title: %@" , proUpgradeProduct.localizedTitle);
NSLog(@"Product description: %@" , proUpgradeProduct.localizedDescription);
NSLog(@"Product price: %@" , proUpgradeProduct.price);
NSLog(@"Product id: %@" , proUpgradeProduct.productIdentifier);
}
for (NSString *invalidProductId in response.invalidProductIdentifiers)
{
NSLog(@"Invalid product id: %@" , invalidProductId);
}
// finally release the reqest we alloc/init’ed in requestProUpgradeProductData

很抱歉，如果其大量的代碼 - 我只是想確認所有相關的代碼都在那裏。
那麼我的回答對你有幫助嗎？你應該接受它，如果它:-) –
