我的 SKProductsRequest 商店套件类崩溃开始我没有经验 inapppurchase 概念我的类在 iOS 4.3 sdk 而不是 iOS 5 sdk 中完美运行。我在控制台上没有收到错误,并且我的应用程序在 SKProductsRequest 开始之前崩溃了请任何人帮助我如何解决这个问题这是我的代码:
#import "StorePurchase.h"
@implementation StorePurchase
@synthesize request = _request;
- (void)loadStore {
if ([SKPaymentQueue canMakePayments]) {
NSLog(@"Parental-controls are disabled");
self.request = [[SKProductsRequest alloc] initWithProductIdentifiers:[NSSet setWithObject:@"com.mycompany.app"]];
self.request.delegate = self;
[self.request start];
}
else {
NSLog(@"Parental-controls are enabled");
}
}
static bool hasAddObserver=NO;
- (void)purchase {
if (!hasAddObserver) {//flag to fix this bug
/*=====================================*/
[[SKPaymentQueue defaultQueue] addTransactionObserver:self];
hasAddObserver=YES;
}
SKMutablePayment *payment = [[SKMutablePayment alloc] init] ;
payment.productIdentifier = @"com.mycompany.app";
payment.quantity = 1;
[[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 found,Magic Box!");
[[NSNotificationCenter defaultCenter] postNotificationName:kProductsLoadedNotification object:@"Product Found..!"];
} else if (!validProduct)
{
NSLog(@"No products available");
[[NSNotificationCenter defaultCenter] postNotificationName:kProductsLoadedNotification object:@"Product Not Found..!"];
}
}
- (void)provideContent:(NSString *)productIdentifier {
NSLog(@"Toggling flag for: %@", productIdentifier);
[[NSUserDefaults standardUserDefaults] setBool:TRUE forKey:productIdentifier];
[[NSUserDefaults standardUserDefaults] synchronize];
//[_purchasedProducts addObject:productIdentifier];
[[NSNotificationCenter defaultCenter] postNotificationName:kProductPurchasedNotification object:productIdentifier];
}
- (void)completeTransaction:(SKPaymentTransaction *)transaction {
NSLog(@"completeTransaction...");
//[self recordTransaction: transaction];
[self provideContent: transaction.payment.productIdentifier];
[[SKPaymentQueue defaultQueue] finishTransaction: transaction];
}
- (void)restoreTransaction:(SKPaymentTransaction *)transaction {
NSLog(@"restoreTransaction...");
//[self recordTransaction: transaction];
[self provideContent: transaction.originalTransaction.payment.productIdentifier];
[[SKPaymentQueue defaultQueue] finishTransaction: transaction];
}
- (void)failedTransaction:(SKPaymentTransaction *)transaction {
if (transaction.error.code != SKErrorPaymentCancelled)
{
NSLog(@"Transaction error: %@", transaction.error.localizedDescription);
}
[[NSNotificationCenter defaultCenter] postNotificationName:kProductPurchaseFailedNotification object:transaction];
[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
}
- (void)paymentQueue:(SKPaymentQueue *)queue restoreCompletedTransactionsFailedWithError:(NSError *)error
{
NSLog(@"<><Canceled!><>");
[[NSNotificationCenter defaultCenter] postNotificationName:kProductPurchaseCanceledNotification object:error];
}
- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions {
for (SKPaymentTransaction *transaction in transactions) {
switch (transaction.transactionState) {
case SKPaymentTransactionStatePurchasing:
// [self completeTransaction:transaction];
break;
case SKPaymentTransactionStatePurchased:
NSLog(@"Purchased");
[self completeTransaction:transaction];
//[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
break;
case SKPaymentTransactionStateRestored:
//[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
NSLog(@"Restored");
[self restoreTransaction:transaction];
break;
case SKPaymentTransactionStateFailed:
if (transaction.error.code != SKErrorPaymentCancelled) {
NSLog(@"An error encounterd");
}
else {
NSLog(@"Cancelled!");
}
//[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
[self failedTransaction:transaction];
break;
}
}
}
我loadStore
在收到错误后调用该方法
SKProductsRequest 在我的应用程序崩溃之前不调用 - (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response 方法!
我的代码有什么问题如何解决!提前致谢!
