ios - MKStoreKit 在 iOS 7 上崩溃并出现 SIGTRAP 错误

Question

我一遍又一遍地查看这个实时应用程序崩溃日志，但找不到问题所在:

1    CoreFoundation  _CFHash + 130
2    CoreFoundation  CFBasicHashFindBucket + 724
3    CoreFoundation  _CFDictionaryGetValue + 99
4    CoreFoundation  -[CFXPreferencesPropertyListSource setValue:forKey:] + 39
5    CoreFoundation  _CFXPreferencesSetValue + 139
6    CoreFoundation  _CFPreferencesSetAppValue + 45
7    Foundation  -[NSUserDefaults(NSUserDefaults) setObject:forKey:] + 61
8    MyApp   -[MKStoreManager rememberPurchaseOfProduct:withReceipt:] (MKStoreManager.m:884)
9    MyApp   -[MKStoreManager provideContent:forReceipt:hostedContent:] (MKStoreManager.m:848)
10   MyApp   -[MKStoreManager restoreTransaction:] (MKStoreManager.m:1004)
11   MyApp   -[MKStoreManager paymentQueue:updatedTransactions:] (MKStoreManager.m:911)
12   StoreKit    __NotifyObserverAboutChanges + 85

这是我认为与崩溃相关的代码(es!):

- (void)rememberPurchaseOfProduct:(NSString*) productIdentifier withReceipt:(NSData*) receiptData {

    NSDictionary *allConsumables = [[MKStoreManager storeKitItems] objectForKey:@"Consumables"];
    if([[allConsumables allKeys] containsObject:productIdentifier])
    {
        NSDictionary *thisConsumableDict = [allConsumables objectForKey:productIdentifier];
        NSInteger quantityPurchased = [[thisConsumableDict objectForKey:@"Count"] integerValue];
        NSString* productPurchased = [thisConsumableDict objectForKey:@"Name"];

        NSInteger oldCount = [[MKStoreManager numberForKey:productPurchased] integerValue];
        NSInteger newCount = oldCount + quantityPurchased;

        [MKStoreManager setObject:[NSNumber numberWithInteger:newCount] forKey:productPurchased];
    }
    else
    {
        [MKStoreManager setObject:[NSNumber numberWithBool:YES] forKey:productIdentifier];

        //set flag in NSUserDefaults as another place we chan check to see if they have purchased the app
        //we may not want to check this, however, as an OR, since it can be easily jailbroken
        [[NSUserDefaults standardUserDefaults] setBool:TRUE forKey:productIdentifier];
        [[NSUserDefaults standardUserDefaults] synchronize];
    }

    [MKStoreManager setObject:receiptData forKey:[NSString stringWithFormat:@"%@-receipt", productIdentifier]];
}

多年来我一直在使用相同的代码，没有任何问题。谁能帮我指出正确的方向？

(太长了所以无法发布其余部分，但如果有人认为它可能有帮助，我可以将其添加到评论中)

Answer 1

productIdentifier 是 nil 正如@rmaddy 在评论中建议的那样。其他开发人员在 MKStoreKit Github 问题上报告了这个问题 https://github.com/MugunthKumar/MKStoreKit/pull/176

建议的修复在这里:https://github.com/dfabulich/MKStoreKit/commit/4b8adb442f1d7b7a9541feab5e319969369d3f95作者:Dan Fabulich(不是我)。

在 MKStoreManager.m -(void) provideContent: (NSString*) productIdentifier 在顶部添加一个 nil 检查:

if (!productIdentifier) {
  NSLog(@"productIdentifier is nil; Apple bug?");
  return;
}
