未调用 configurePersistentStoreCoordinator 来保存 NSPersistentDocument

2023-12-10

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。但当我保存它时write(to: ofType: for: absoluteOriginalContentsURL:)被称为但它变成了configurePersistentStoreCoordinator(for: ofType: modelConfiguration: storeOptions:)没有被调用。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).

第一次尝试是我自己称呼它，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（通过菜单命令另存为后开始第二个 configurePersistentStoreCoordinator 输出）：

VTDocment.configurePersistentStoreCoordinator for Unsaved Visual Thinking with IBIS Document 12.ibisVT
VTDocment.configurePersistentStoreCoordinator for test.ibisVT
Now... VTDocment.write to test.ibisVT

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

提前谢谢了。

UpdateTora 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。 :-)

Another, simpler workaround:

以下代码有一个错误。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
  }

}

Added:

这个解决方法将是一个实用的解决方案，直到他们增强NSPersistentDocument.write(to...)考虑选项或者他们实施其他方式来处理选项。这些选项将提供给NSPersistentStoreCoordinator.migratePersistentStore(...)然后用于实例化NSPersistentStore.

错误修复版本：

前面的解决方法中存在一个错误。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
  }

}
