核心数据迁移 - Appstore 构建在 iOS 8 台设备上崩溃，正在 iOS 9 台设备上运行
Core data migration - Appstore build crashing on iOS 8 devices, working on iOS 9
我的应用商店更新版本崩溃，这是核心数据崩溃，但我只在 iOS 8 台设备上遇到此崩溃，它在 iOS 9 台设备上运行良好。
我已经正确执行了轻量级迁移，并添加了新模型版本，将旧模型版本作为基础，在添加 "addPersistentStoreWithType".
的同时还在选项中添加了字典
ManagedObjectModel
lazy var managedObjectModel: NSManagedObjectModel = {
// The managed object model for the application. This property is not optional. It is a fatal error for the application not to be able to find and load its model.
let modelURL = NSBundle.mainBundle().URLForResource("abcProject", withExtension: "momd")
NSLog("Url is - \(modelURL)")
return NSManagedObjectModel(contentsOfURL: modelURL!)!
}()
PersistentStoreCoordinator
lazy var persistentStoreCoordinator: NSPersistentStoreCoordinator? = {
var coordinator: NSPersistentStoreCoordinator? = NSPersistentStoreCoordinator(managedObjectModel: self.managedObjectModel)
let url = self.applicationDocumentsDirectory.URLByAppendingPathComponent("abcProject")
var error: NSError? = nil
var failureReason = "There was an error creating or loading the application's saved data."
do {
let mOptions = [NSMigratePersistentStoresAutomaticallyOption: true, NSInferMappingModelAutomaticallyOption: true]
NSLog("TEST564 - 7 URL - \(url)")
try coordinator!.addPersistentStoreWithType(NSSQLiteStoreType, configuration: nil, URL: url, options: mOptions)
} catch var error1 as NSError {
error = error1
coordinator = nil
// Report any error we got.
var dict = [String: AnyObject]()
dict[NSLocalizedDescriptionKey] = "Failed to initialize the application's saved data"
dict[NSLocalizedFailureReasonErrorKey] = failureReason
dict[NSUnderlyingErrorKey] = error
error = NSError(domain: "YOUR_ERROR_DOMAIN", code: 9999, userInfo: dict)
// Replace this with code to handle the error appropriately.
// abort() causes the application to generate a crash log and terminate. You should not use this function in a shipping application, although it may be useful during development.
NSLog("TEST564 Unresolved error \(error), \(error!.userInfo)")
abort()
} catch {
fatalError()
NSLog("TEST564 FATAL error")
}
return coordinator
}()
以上是我的一套代码供参考。我到处搜索，只得到有关轻量级迁移的详细信息。

错误，Can't find model for source store 表示当应用程序尝试迁移持久存储时，它找不到用于创建存储的数据模型。数据迁移需要新旧数据存储。旧的用于加载数据，新的用于更新数据以供将来使用。
这在 iOS 9 上起作用的原因是 iOS 9 添加了模型缓存以用于 SQLite 存储的轻量级迁移。因此，在 iOS 9 上，您可以在没有旧模型的情况下成功迁移，因为旧版本将被自动缓存。此功能在 iOS 8 上不可用，因此如果您仍然支持 8，那么您仍然需要在您的应用中包含该模型的旧版本。
为了避免崩溃，我为 iOS 8 创建了新数据库，因为我不需要那么多现有数据。
我更改了我的商店网址
let url = self.applicationDocumentsDirectory.URLByAppendingPathComponent("abcProject")
至
let url:NSURL
if (OS_VERSION<9.0)
{
url = self.applicationDocumentsDirectory.URLByAppendingPathComponent("abcProject1")
}
else
{
url = self.applicationDocumentsDirectory.URLByAppendingPathComponent("abcProject")
}
这解决了我的崩溃问题。
最后我通过简单的更改解决了问题。
较早的代码 :-
url = self.applicationDocumentsDirectory.URLByAppendingPathComponent("abcProject1")
固定码 :-
url = self.applicationDocumentsDirectory.URLByAppendingPathComponent("abcProject1.sqlite")
添加 <.sqlite> 扩展到我的 url 路径解决了我的问题。
它已针对所有可能的场景进行了全面测试。
谢谢大家的帮助。

错误，Can't find model for source store 表示当应用程序尝试迁移持久存储时，它找不到用于创建存储的数据模型。数据迁移需要新旧数据存储。旧的用于加载数据，新的用于更新数据以供将来使用。
这在 iOS 9 上起作用的原因是 iOS 9 添加了模型缓存以用于 SQLite 存储的轻量级迁移。因此，在 iOS 9 上，您可以在没有旧模型的情况下成功迁移，因为旧版本将被自动缓存。此功能在 iOS 8 上不可用，因此如果您仍然支持 8，那么您仍然需要在您的应用中包含该模型的旧版本。
为了避免崩溃，我为 iOS 8 创建了新数据库，因为我不需要那么多现有数据。
我更改了我的商店网址
let url = self.applicationDocumentsDirectory.URLByAppendingPathComponent("abcProject")
至
let url:NSURL
if (OS_VERSION<9.0)
{
url = self.applicationDocumentsDirectory.URLByAppendingPathComponent("abcProject1")
}
else
{
url = self.applicationDocumentsDirectory.URLByAppendingPathComponent("abcProject")
}
这解决了我的崩溃问题。
最后我通过简单的更改解决了问题。
较早的代码 :-
url = self.applicationDocumentsDirectory.URLByAppendingPathComponent("abcProject1")
固定码 :-
url = self.applicationDocumentsDirectory.URLByAppendingPathComponent("abcProject1.sqlite")
添加 <.sqlite> 扩展到我的 url 路径解决了我的问题。 它已针对所有可能的场景进行了全面测试。 谢谢大家的帮助。
