核心數據 - 持久存儲無法在iOS 5.1上創建

當我想創建持久存儲時出現錯誤。當我爲iOS 5.0構建時，沒有錯誤，核心數據成功運行。核心數據 - 持久存儲無法在iOS 5.1上創建

下面是創建持久存儲的代碼：

+ (NSManagedObjectContext *)getContext { 

    NSDictionary *options = [NSDictionary dictionaryWithObjectsAndKeys:[NSNumber numberWithBool:YES],NSMigratePersistentStoresAutomaticallyOption, 
          [NSNumber numberWithBool:YES], 
          NSInferMappingModelAutomaticallyOption, nil]; 


    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
    NSString *basePath = ([paths count] > 0) ? [paths objectAtIndex:0] : nil; 
    NSURL *storeUrl = [NSURL fileURLWithPath:[basePath stringByAppendingFormat:@"Database.sqlite"]]; 
    NSPersistentStoreCoordinator *persistentStoreCoordinator = [[NSPersistentStoreCoordinator alloc] initWithManagedObjectModel:[NSManagedObjectModel mergedModelFromBundles:nil]]; 
    NSError *error = nil; 

    if (![persistentStoreCoordinator addPersistentStoreWithType:NSSQLiteStoreType configuration:nil URL:storeUrl options:options error:&error]) { 
     NSLog(@"error loading persistent store.."); 
     [[NSFileManager defaultManager] removeItemAtPath:storeUrl.path error:nil]; 
     if (![persistentStoreCoordinator addPersistentStoreWithType:NSSQLiteStoreType configuration:nil URL:storeUrl options:options error:&error]) { 
      NSLog(@"Unresolved error %@, %@", error, [error userInfo]); 
      //abort(); 
     } 
    } 


    NSManagedObjectContext *context = [[NSManagedObjectContext alloc] init]; 
    [context setPersistentStoreCoordinator:persistentStoreCoordinator]; 

    return context; 


}

嘗試從Simulator/Device中刪除應用程序並再次運行，這可能會解決您的問題。謝謝 – SALMAN 2012-07-15 14:23:38
