如何在特定時間和日期添加日曆事件？

Question

• 我從日期選擇器中獲取日期和時間，並且我已將它設置爲爲字符串格式。
• 我想在給定的日期和時間添加事件。
• 我想設置兩個提醒，提醒之前給予特定的時間，如「5分鐘，15分鐘，30分鐘」。 事件時間第二次提醒。
• 在下面的代碼中，我需要做什麼來完成我的要求。

給出任何建議或想法solev它 感謝

獲取日期和時間從日期選擇器

let dateFormatter = DateFormatter() 

    dateFormatter.dateFormat = "YYYY-MM-dd" 
    routineDate = dateFormatter.string(from: self.datetimepicker.date) 
    print(routineDate) 

    let dateFormatter = DateFormatter() 

    dateFormatter.dateFormat = "HH:mm a" 
    routineTime = dateFormatter.string(from: self.datetimepicker.date) 
    print(routineTime) 

創建和保存EKEvent這裏：

let dateFormatter = DateFormatter() 
    dateFormatter.dateStyle = .short 
    dateFormatter.dateFormat = "YYYY-MM-dd" 
    let startDATE = dateFormatter.date(from: routineDate) 
    let endDATE = dateFormatter.date(from: routineDate) 

    print(routineDate) 
    if temptypeID == "1" { 
     let event:EKEvent = EKEvent(eventStore: appleEventStore) 
     event.title = tempDescription 

    // what should i need to change here for specific date and time? 

     event.startDate = (startDATE?.addingTimeInterval(60*60))! 
     event.endDate = (endDATE?.addingTimeInterval(60*60))! 
     event.isAllDay = false 
     event.notes = "This is a note" 
     event.calendar = cal 

     do { 
      try appleEventStore.save(event, span: .thisEvent) 
      print("events added with dates:") 

     // what should changes i need to do here for alert ? 

      let alarm = EKAlarm(absoluteDate: Date(timeInterval: -3600, since: event.startDate)) 

     event.addAlarm(alarm) 

     } catch let e as NSError { 
      print(e.description) 
      return 
     } 
     print("Saved Event") 
    } 

Answer 1

嘗試將日期保存爲日期：

let startDate = self.datetimepicker.date 
let endDate = startDate.addingTimeInterval(3600 as TimeInterval) 

然後使用這些創建活動：

let event:EKEvent = EKEvent(eventStore: appleEventStore) 
event.title = tempDescription 

// what should i need to change here for specific date and time? 

event.startDate = startDate 
event.endDate = endDate 
event.isAllDay = false 
event.notes = "This is a note" 
event.calendar = cal 

do { 
    try appleEventStore.save(event, span: .thisEvent) 
    print("events added with dates:") 

    // Adding an Alert 1 hour before the startDate 
    let reminder = EKAlarm(relativeOffset: -3600) 
    event.addAlarm(reminder) 
    print("Saved Event") 
} catch let e as NSError { 
    print(e.description) 
    return 
} 

而且，你的事件的創建不應該是你的DateFormatter的聲明中。
