我的商店套件类崩溃SKProductsRequest开始我没有经验inapppurchase概念我的类在iOS 4.3 sdk完美工作而不是iOS 5 sdk。我没有在控制台上出现错误，我的应用程序在SKProductsRequest启动之前崩溃了，请任何人帮我解决这个问题，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;
}
}
}
我在收到错误后调用loadStore方法
SKProductsRequest在崩溃我的应用程序之前没有调用 - （void）productsRequest：（SKProductsRequest *）请求didReceiveResponse：（SKProductsResponse *）响应方法！
我的代码中有什么错误如何修复！ 在此先感谢！
答案 0 :(得分：1)
我已经在我的应用程序中使用此代码完成了应用内购买的代码，没有问题
- (void)loadStore
{
// restarts any purchases if they were interrupted last time the app was open
[[SKPaymentQueue defaultQueue] addTransactionObserver:self];
// get the product description (defined in early sections)
[self requestProUpgradeProductData];
}
- (void)requestProUpgradeProductData
{
NSSet *productIdentifiers = [NSSet setWithObject:kInAppPurchaseProUpgradeProductId];
productsRequest = [[SKProductsRequest alloc] initWithProductIdentifiers:productIdentifiers];
productsRequest.delegate = self;
[productsRequest start];
// we will release the request object in the delegate callback
}
之后它将调用此方法
- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response
{
NSArray *products = response.products;
proUpgradeProduct = [products count] == 1 ? [[products objectAtIndex:0] retain] : nil;
if (proUpgradeProduct)
{
NSLog(@"Product title: %@" , proUpgradeProduct.localizedTitle);
NSLog(@"Product description: %@" , proUpgradeProduct.localizedDescription);
NSLog(@"Product price: %@" , proUpgradeProduct.price);
NSLog(@"Product id: %@" , proUpgradeProduct.productIdentifier);
if ([self canMakePurchases]) {
if ([self respondsToSelector:@selector(purchaseProUpgrade)]) {
[self purchaseProUpgrade];
}
}
else {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:[self languageSelectedStringForKey:@"Error"] message:@"Cannot connect to Store.\n Please Enable the Buying in settings" delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil, nil];
[alert show];
[alert release];
}
}
for (NSString *invalidProductId in response.invalidProductIdentifiers)
{
[SVProgressHUD dismiss];
[cancelButton setEnabled:YES];
[buyNowButton setEnabled:YES];
[restoreButton setEnabled:YES];
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Warning" message:@"Error occured" delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil, nil];
[alert show];
[alert release];
NSLog(@"Invalid product id: %@" , invalidProductId);
}
// finally release the reqest we alloc/init’ed in requestProUpgradeProductData
[productsRequest release];
[[NSNotificationCenter defaultCenter] postNotificationName:kInAppPurchaseManagerProductsFetchedNotification object:self userInfo:nil];
}
- (void)completeTransaction:(SKPaymentTransaction *)transaction
{
[self recordTransaction:transaction];
[self provideContent:transaction.payment.productIdentifier];
[self finishTransaction:transaction wasSuccessful:YES];
}
- (void)purchaseProUpgrade
{
[SVProgressHUD showInView:self.view status:[self languageSelectedStringForKey:@"Connecting Store"] networkIndicator:YES];
SKPayment *payment = [SKPayment paymentWithProductIdentifier:kInAppPurchaseProUpgradeProductId];
[[SKPaymentQueue defaultQueue] addPayment:payment];
}
- (void)recordTransaction:(SKPaymentTransaction *)transaction
{
if ([transaction.payment.productIdentifier isEqualToString:kInAppPurchaseProUpgradeProductId])
{
// save the transaction receipt to disk
[[NSUserDefaults standardUserDefaults] setValue:transaction.transactionReceipt forKey:@"proUpgradeTransactionReceipt" ];
[[NSUserDefaults standardUserDefaults] synchronize];
}
}
最后这个方法
- (void)finishTransaction:(SKPaymentTransaction *)transaction wasSuccessful:(BOOL)wasSuccessful
{
// remove the transaction from the payment queue.
[[SKPaymentQueue defaultQueue] finishTransaction:transaction];
NSDictionary *userInfo = [NSDictionary dictionaryWithObjectsAndKeys:transaction, @"transaction" , nil];
if (wasSuccessful)
{
//Write your transaction complete statement required for your project
}
