我最近通过 iTunes Connect 向 Apple 提交了我的应用程序，它现在已在 iTunes 商店中。然而，当我把它下载到朋友的 iPhone 上时，它立即崩溃了。我在 iPhone 模拟器和 iPad 上进行了测试（我没有 iPhone）。因此，我将 iPhone 插入电脑并从中获取了以下崩溃日志：

接下来，我删除了原来的应用程序，并通过xcode 4将其放在iPhone上。我尝试以这种方式运行它，它崩溃并出现以下错误：

我尝试将以下方法中的 pathForResource 字符串替换为我最近的商店 (Appv4) 的确切名称，但它告诉我数据库的路径为空。
- (NSManagedObjectModel *)managedObjectModel {
if (managedObjectModel_ != nil) {
return managedObjectModel_;
}
NSString *modelPath = [[NSBundle mainBundle] pathForResource:@"App" ofType:@"momd"];
NSURL *modelURL = [NSURL fileURLWithPath:modelPath];
managedObjectModel_ = [[NSManagedObjectModel alloc] initWithContentsOfURL:modelURL];
return managedObjectModel_;
}
在尝试通过 xcode 在 iPhone 上运行该应用程序几次后，它突然开始工作了。然而，应用商店上的版本却没有出现同样的情况。
请帮忙！我不知道出了什么问题。

Typical reasons for an error here include:
* The persistent store is not accessible;
* The schema for the persistent store is incompatible with current managed object model.
Check the error message to determine what the actual problem was.
If the persistent store is not accessible, there is typically something wrong with the file path. Often, a file URL is pointing into the application's resources directory instead of a writeable directory.
If you encounter schema incompatibility errors during development, you can reduce their frequency by:
* Simply deleting the existing store:
[[NSFileManager defaultManager] removeItemAtURL:storeURL error:nil]
* Performing automatic lightweight migration by passing the following dictionary as the options parameter:
[NSDictionary dictionaryWithObjectsAndKeys:[NSNumber numberWithBool:YES],NSMigratePersistentStoresAutomaticallyOption, [NSNumber numberWithBool:YES], NSInferMappingModelAutomaticallyOption, nil];
Lightweight migration will only work for a limited set of schema changes; consult "Core Data Model Versioning and Data Migration Programming Guide" for details.
