ios - requestAccessToEntityType :completion: has been deprecated calling this is no longer allowed. 改为使用 requestFullAccessToEventsWithCompletion:

Question

今天，我已将 Xcode 更新至 15.0，将 iPhone 更新至 iOS 17，但现在我在日历中写入 EKEvent 的代码不再起作用。它在早期版本的 iOS 中运行良好。我是否存在兼容性问题或者还有其他原因？

错误是这样的:

错误:-requestAccessToEntityType:completion: 已弃用 - 不再允许调用此方法。相反，请使用 -requestFullAccessToEventsWithCompletion:、-requestWriteOnlyAccessToEventsWithCompletion: 或 -requestFullAccessToRemindersWithCompletion:

我的代码如下所示:

    func accesCalenderToAddEvent() {
        let eventStore: EKEventStore = EKEventStore()
        eventStore.requestAccess(to: EKEntityType.event) { granted, error in
            DispatchQueue.main.async {
                if (granted) && (error == nil) {
                    let event = EKEvent(eventStore: self.eventStore)
                    event.title = "Event 1"
                    event.startDate = Date()
                    event.endDate = Date()
                    
                    let eventController = EKEventEditViewController()
                    eventController.event = event
                    eventController.eventStore = eventStore
                    eventController.editViewDelegate = self
                    self.present(eventController, animated: true, completion: nil)
                } else {
                    let alertController = UIAlertController(title: "Calendar Permission Required", message: "Please enable Calender permissions in settings.", preferredStyle: UIAlertController.Style.alert)
                    let okAction = UIAlertAction(title: "OK", style: .default, handler: {(cAlertAction) in
                        //Redirect to Settings app
                        UIApplication.shared.open(URL(string:UIApplication.openSettingsURLString)!)
                    })
                    alertController.addAction(okAction)
                    self.present(alertController, animated: true, completion: nil)
                }
            }
        }
    }

请向我建议 iOS 17 的解决方案，因为在早期版本中它适合我。

提前致谢。

iOS 17 的权限范围已更改为包括读取、写入和完全访问权限，而 iOS 16 仅具有完全访问权限。当您在 iOS 17 上使用 eventStore.requestAccess() 时，这会导致错误，但在 iOS 16 上则不会。

要在 iOS 17 中提供支持，请编写如下代码:

if #available(iOS 17.0, *) {
    eventStore.requestWriteOnlyAccessToEvents { granted, error in
        DispatchQueue.main.async {
            //write the existing logic here
        }
    }
}else {
    //put the old code here so it’s been working in earlier versions before iOS 17.
}

注意:

If you are only using EKEventEditViewController then you no need to take the any permission as per this official doc: Documentation
