macos - 未调用 configurePersistentStoreCoordinator 来保存 NSPersistentDocument

我在保存 NSPersistentDocument 时遇到了奇怪的行为。我可以创建一个自动保存的新文档,没有问题。但是当我保存它时 write(to: ofType: for:absoluteOriginalContentsURL:) 被调用,但它变成了 configurePersistentStoreCoordinator(for: ofType: modelConfiguration: storeOptions:) 不是' t 打电话来。不幸的是,因为我需要配置商店。原因是我需要将 NSColor 注册为可解码 options[NSBinaryStoreSecureDecodingClasses] = NSSet(object: NSColor.self)

第一次尝试是自己调用它,但这并没有引导我到任何地方。自己调用它并没有按预期注册设置。

我的 NSPersistentDocument 中的代码如下所示:

 override func configurePersistentStoreCoordinator(for url: URL, ofType fileType: String, modelConfiguration configuration: String?, storeOptions: [String : Any]? = nil) throws {
Swift.print("VTDocment.configurePersistentStoreCoordinator for \(url.lastPathComponent)")
var options = addOptions(to: storeOptions)
try super.configurePersistentStoreCoordinator(for: url, ofType: fileType, modelConfiguration: configuration, storeOptions: options)
}

func addOptions(to: [String : Any]?) -> [String : Any] {
var options = to != nil ? to! : [String:Any]()
if #available(OSX 10.13, *) {
options[NSBinaryStoreSecureDecodingClasses] = NSSet(object: NSColor.self)
}
options[NSMigratePersistentStoresAutomaticallyOption] = true
options[NSInferMappingModelAutomaticallyOption] = true
return options
}

override func write(to url: URL, ofType typeName: String, for saveOperation: NSDocument.SaveOperationType, originalContentsURL absoluteOriginalContentsURL: URL?) throws {
try self.configurePersistentStoreCoordinator(for: url, ofType: typeName, modelConfiguration: "Document")
do {
Swift.print("Now... VTDocment.write to \(url.lastPathComponent)")
try super.write(to: url, ofType: typeName, for: saveOperation, originalContentsURL: absoluteOriginalContentsURL)
} catch {
Swift.print("VTDocment.write error: \(error)")
}
}

结果是以下输出(第二个 configurePersistentStoreCoordinator 输出在通过菜单命令另存为后开始):

VTDocment.configurePersistentStoreCoordinator for Unsaved Visual Thinking with IBIS Document 12.ibisVT

编辑感谢@Tora 的提问!这是相关的堆栈跟踪。它不是来自同一个 session ,但会导致相同的结果。

提前非常感谢。

更新Tora 的解决方案(通过方法调配)效果很好。但是,有时(不确定何时)可能会导致相同的问题。这是更新的堆栈跟踪。这很神秘。 :-)

最佳答案

另一种更简单的解决方法:

下面的代码有一个错误。请参阅下面引用的错误修复版本。

extension NSPersistentStoreCoordinator {

@objc func x_migratePersistentStore(_ store: NSPersistentStore, to URL: URL, options: [AnyHashable : Any]? = nil, withType storeType: String) throws -> NSPersistentStore {
var opt: [AnyHashable : Any] = options ?? [:]

if #available(OSX 10.13, *) {
opt[NSBinaryStoreSecureDecodingClasses] = NSSet(array: [ NSColor.self ])
}

return try x_migratePersistentStore(store, to: URL, options: opt, withType: storeType)
}

}

class Document: NSPersistentDocument {

override init() {
super.init()

let s1 = #selector(NSPersistentStoreCoordinator.migratePersistentStore(_:to:options:withType:))
let s2 = #selector(NSPersistentStoreCoordinator.x_migratePersistentStore(_:to:options:withType:))
let m1 = class_getInstanceMethod(NSPersistentStoreCoordinator.self, s1)!
let m2 = class_getInstanceMethod(NSPersistentStoreCoordinator.self, s2)!
method_exchangeImplementations(m1, m2)
}

override func configurePersistentStoreCoordinator(for url: URL, ofType fileType: String, modelConfiguration configuration: String?, storeOptions: [String : Any]? = nil) throws {
// keep yours
}

}

已添加:

此解决方法将成为一个实用的解决方案,直到他们增强 NSPersistentDocument.write(to...) 以考虑选项或实现其他方法来处理选项。这些选项将提供给 NSPersistentStoreCoordinator.migratePercientStore(...),然后用于实例化 NSPersistentStore

错误修复版本:

前面的解决方法中存在错误。打开文档文件、创建新文件、进行更改、等待文档自动保存三十秒、关闭它们和/或随机另存为它们都会导致初始错误。由克努普巫师报道。

这是一个使用单例的固定版本,以确保仅应用一次混合。

extension NSPersistentStoreCoordinator {

@objc func x_migratePersistentStore(_ store: NSPersistentStore, to URL: URL, options: [AnyHashable : Any]? = nil, withType storeType: String) throws -> NSPersistentStore {
var opt: [AnyHashable : Any] = options ?? [:]

if #available(OSX 10.13, *) {
opt[NSBinaryStoreSecureDecodingClasses] = NSSet(array: [ NSColor.self ])
}

return try x_migratePersistentStore(store, to: URL, options: opt, withType: storeType)
}

class MigratePersistentStoreInitializer {
init() {
let s1 = #selector(NSPersistentStoreCoordinator.migratePersistentStore(_:to:options:withType:))
let s2 = #selector(NSPersistentStoreCoordinator.x_migratePersistentStore(_:to:options:withType:))
let m1 = class_getInstanceMethod(NSPersistentStoreCoordinator.self, s1)!
let m2 = class_getInstanceMethod(NSPersistentStoreCoordinator.self, s2)!
method_exchangeImplementations(m1, m2)
}

static let singlton = MigratePersistentStoreInitializer() // Lazy Stored Property
}

}

class Document: NSPersistentDocument {

override init() {
super.init()
let _ = NSPersistentStoreCoordinator.MigratePersistentStoreInitializer.singlton
}

override func configurePersistentStoreCoordinator(for url: URL, ofType fileType: String, modelConfiguration configuration: String?, storeOptions: [String : Any]? = nil) throws {
// keep yours
}

}
