ios - 更改日历时未保存 EKEventEditViewController 更改

Question

当在 EKEventEditViewController 实例上编辑事件并选择另一个日历时，事件上的日历会发生变化，但对其他属性(如标题)的更改会丢失。

如果我不选择其他日历，更改将按预期保留。

这是我加载编辑器时的代码

let editorVC = EKEventEditViewController()
eventKitEditorViewController = editorVC // eventKitEditorViewController is a class variable

editorVC.event = ekEvent // ekEvent is the supplied event to edit
editorVC.modalPresentationStyle = .Popover
editorVC.eventStore = OP1EventKitManager.sharedInstance.eventStore // the store is on a singleton object
editorVC.editViewDelegate = self

rootVC.presentViewController(editorVC, animated: true, completion: nil)

/// DELEGATE METHOD

    func eventEditViewController(controller: EKEventEditViewController, didCompleteWithAction action: EKEventEditViewAction) {
        print(action)
        controller.dismissViewControllerAnimated(true, completion: nil)
    }

当 eventEditViewController didCompleteWithAction 完成时，我是否需要做任何额外的事情？

在您的回调中，您没有保存事件。尝试在回调中保存您的事件，看看是否能解决问题。类似这样的东西:

let event = controller.event!

 do {
     try eventStore.saveEvent(event, span: .ThisEvent, commit: true)
 } catch {
     print("Could not update the event store with supplied changes")
 }
