业余人士。按下“购买”按钮时，代码效果很好（我使用断点来挑选有问题的行，见下文），直到调用canMakePayments为止。处理IAP的场景包括Gamescene，InAppManager，InAppObserver，ORPurchaseProduct;所有相关代码如下。
我的应用在break之后崩溃了。一切正常，直到break行。这是在InAppManager.m内。向下滚动以查看InAppManager.m中的所有代码。应用程序崩溃后，IAP类型继续显示alertView要求我购买。点击购买后，alertView消失，应用程序不响应任何触摸。当我关闭应用程序并打开它时，它表明我已经购买了产品，一切都运行良好。我分享了所有信息，提前致谢。
有人可以告诉我指示。
-(void) buyFeature:(NSString*) featureID {
if ([SKPaymentQueue canMakePayments]) {
NSLog(@"Can make payments");
SKProduct* selectedProduct;
for (int i=0; i < [purchaseableProducts count]; i++) {
selectedProduct = [purchaseableProducts objectAtIndex:i];
if ([[selectedProduct productIdentifier] isEqualToString:featureID]) {
// if we found a SKProduct in the purchaseableProducts array with the same ID as the one we want to buy, we proceed by putting it in the payment queue.
SKPayment* payment = [SKPayment paymentWithProduct:selectedProduct];
[[SKPaymentQueue defaultQueue] addPayment:payment];
NSLog(@"Proceeding by putting the product in the payment queue");
break;
}
else {
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Sorry" message:@"You can't purchase from the App Store" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
[alert show];
}
}
}
}
这是崩溃后在控制台中的样子

我在GameScene中有这些行，一切都开始了，我只选择了相关的代码。
-(void)didMoveToView:(SKView *)view {
/* Setup your scene here */
[InAppManager sharedManager];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(unlockProduct1) name:@"feature1Purchased" object:nil];
}
-(void) unlockProduct1 {
NSLog(@"this class knows we purchased the product!");
}
我在ORPurchaseProduct.m中有这些行。在这里，我有购买按钮，它检查产品是否已经购买。我从GameScene过渡到这个。
-(void)didMoveToView:(SKView *)view
{
[InAppManager sharedManager];
if ( [[InAppManager sharedManager] isFeature1PurchasedAlready] == NO) {
NSLog(@" product was not bought yet");
[self createBuyButton:@"BUY"];
} else {
NSLog(@" product was bought");
[self createBuyButton:alreadyBoughtMessage];
}
}
-(void) createBuyButton:(NSString*) theMessage {
UIFont* theFont = [UIFont fontWithName:@"BUY" size:18];
thePurchaseButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
if( [theMessage isEqualToString:alreadyBoughtMessage]) {
[thePurchaseButton addTarget:self action:@selector(doNothing) forControlEvents:UIControlEventTouchUpInside];
NSLog(@"Already bought message: we are here");
} else {
[thePurchaseButton addTarget:[InAppManager sharedManager] action:@selector(buyFeature1) forControlEvents:UIControlEventTouchUpInside];
}
[thePurchaseButton.titleLabel setFont:theFont];
[thePurchaseButton setTitle:theMessage forState:UIControlStateNormal];
[thePurchaseButton setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
[thePurchaseButton setBackgroundColor:[UIColor blackColor]];
thePurchaseButton.frame = CGRectMake(80, 380, 160, 30);
[self.view addSubview:thePurchaseButton];
}
-(void)doNothing
{
NSLog(@"Nothing to be done because the product is already bought!");
}
答案 0 :(得分：0)
我注释掉了这行代码，一切顺利，它出现在AppDelegate的applicationWillResignActive方法中。谢谢你们。
SKView *view = (SKView *)self.window.rootViewController.view;
((GameScene *)view.scene).gamePaused = YES;
