MKStoreKit崩溃与SIGTRAP错误

Question

我已经一遍又一遍地这个活的应用程序崩溃日志，并不能发现问题：

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 

这里是我认为这是与崩溃相关的代码（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]]; 
} 

我一直使用这个相同的代码多年没有问题。任何人都可以请帮助指出我在正确的方向吗？

Answer 1

productIdentifier是nil正如@rmaddy在评论中所暗示的那样。其他开发人员在MKStoreKit Github问题上报告此问题https://github.com/MugunthKumar/MKStoreKit/pull/176

建议的修复程序位于：Dan Fabulich（不是我）的https://github.com/dfabulich/MKStoreKit/commit/4b8adb442f1d7b7a9541feab5e319969369d3f95。

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