Question

对于我的EVReflection库，我遇到了一个EKEvent镜像没有返回任何信息的情况。即使在完成基础知识时镜子也没有返回任何内容。在镜像线后设置断点时，您将看到镜像对象中没有任何内容。这是一个错误还是我错过了什么？

更新我使用旧的Objective C objc_property_t和property_getName函数扩展了获取属性的演示。它将返回属性列表。但是当你得到.value（forKey：

）时会崩溃

    // Eventkit is not supported on tvOS

import XCTest
import Foundation
import EventKit


let store = EKEventStore()

class EVReflectionEventKitTests: XCTestCase {
    func testEventKit() {

        let exp = expectation(description: "eventStore")

        store.requestAccess(to: .event, completion: { (granted, error) in
            let event = EKEvent(eventStore: store)
            event.startDate = Date().addingTimeInterval(10000)
            event.title = "title"
            event.location = "here"
            event.endDate = Date().addingTimeInterval(20000)
            event.notes = "notes"

            event.calendar = store.defaultCalendarForNewEvents
            event.addAlarm(EKAlarm(absoluteDate: Date().addingTimeInterval(10000)))

            //WARNING: You will get events in your agenda! Disable next line if you don't want that
            //try? store.save(event, span: EKSpan.thisEvent, commit: true)

            let m = Mirror(reflecting: event)
            print("mirror children = \(m.children.count)")

            let oc = self.properties(event)
            print(oc)

            for p in oc {
                var value: Any? = nil
                value = event.value(forKey: p)

我制作了一个SERIALIZER.SWIFT类，就像你提供的github中的例子一样：

import Foundation
import EventKit
import EVReflection

class serializedEvent: EVObject {
var myEvent: EKEvent = EKEvent(eventStore: globalStore)
//globalstore is an EKEventstore global object

然后在我的一个控制器中（我只有一个完整的事件名为：使用EKalarms类型的警报创建的事件和EKRecurrencyRule类型的重复规则）：

print("event before serialization :")
  print(event)
  let serEvent: serializedEvent = serializedEvent()
  serEvent.myEvent=event

  let jsonEvent = serEvent.toJsonString()

  let newEvent = serializedEvent(json: jsonEvent).myEvent
  print("newEvent: =")
  print(newEvent)

这是一个真实的输出示例：

event before serialization :
   EKEvent <0x174130040>

     EKEvent <0x174130040>

  ); 
     URL =          (null); 
      lastModified = 2016-06-06 15:15:17 +0000;

  FREQ=YEARLY;INTERVAL=1;BYMONTH=6;BYMONTHDAY=7; 
 attendees =    (null); 
 travelTime =   (null); 
 startLocation =    (null);
  };

但是当我们询问它是否有警报（它应该有，看着输出）

print(newEvent.hasAlarms)

它以

失败

 19170:5969208] -[__NSCFString hasAlarms]: unrecognized selector sent to instance 0x17425d340

这很棘手:(

编辑：如果在SERIALIZER.SWITF类中我添加：扩展EKEvent：EVReflectable {} 那么newEvent就是空的。

..真的很棘手：D

EKEvent的镜像不显示数据
