Set a second reminder when create reminder button pressed in Swift 3 - ios

Question

I've created an appointment reminder app for customers but a few have said they would like the app to give them an earlier notification say one day in advance (24 hours) as well as at the time of the appointment, but I'm unsure how I can edit my code to do this.
Here is my working code that shows the appointment at the chosen time on the date picker:
import UIKit
import EventKit
class RemindersViewController: UIViewController {
#IBOutlet weak var reminderText: UITextField!
#IBOutlet weak var myDatePicker: UIDatePicker!
#IBOutlet weak var activityIndicator: UIActivityIndicatorView!
let appDelegate = UIApplication.shared.delegate
as! AppDelegate
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
#IBAction func setReminder(_ sender: AnyObject) {
if reminderText.text == "" {
// Create the alert controller
let alertController = UIAlertController(title: "Information Needed", message: "Please type in your treatment and select the correct date and time you wish to be reminded about before pressing the Create Appointment Reminder button.", preferredStyle: .alert)
// Create the actions
let okAction = UIAlertAction(title: "Got It", style: UIAlertActionStyle.default) {
UIAlertAction in
NSLog("OK Pressed")
}
// Add the actions
alertController.addAction(okAction)
// Present the controller
self.present(alertController, animated: true, completion: nil)
} else {
activityIndicator.startAnimating()
let eventStore = EKEventStore()
eventStore.requestAccess(
to: EKEntityType.reminder, completion: {(granted, error) in
if !granted {
print("Access to store not granted")
print(error!.localizedDescription)
} else {
print("Access granted")
self.createReminder(in: eventStore)
}
})
}
self.reminderText.resignFirstResponder()
}
func textFieldShouldReturn(_ textField: UITextField) -> Bool {
textField.resignFirstResponder()
return true
}
func createReminder(in eventStore: EKEventStore) {
let reminder = EKReminder(eventStore: eventStore)
reminder.title = reminderText.text! + " " + "(Pose Beauty Salon)"
reminder.calendar =
eventStore.defaultCalendarForNewReminders()
let date = myDatePicker.date
let alarm = EKAlarm(absoluteDate: date)
reminder.addAlarm(alarm)
do {
try eventStore.save(reminder,
commit: true)
} catch let error {
print("Reminder failed with error \(error.localizedDescription)")
}
// Create the alert controller
let alertController = UIAlertController(title: "Reminder Created Successfully", message: "Your \(reminderText.text!) appointment reminder at Pose Beauty Salon has been successfully created in your iPhone Reminders app. Thank You!", preferredStyle: .alert)
// Create the actions
let okAction = UIAlertAction(title: "OK", style: UIAlertActionStyle.default) {
UIAlertAction in
NSLog("OK Pressed")
self.reminderText.text = ""
self.activityIndicator.stopAnimating()
}
// Add the actions
alertController.addAction(okAction)
// Present the controller
self.present(alertController, animated: true, completion: nil)
}
override func touchesBegan(_ touches: Set<UITouch>, with event: UIEvent?) {
reminderText.endEditing(true)
}
}
I've changed my code as follows but I only get the reminder saved once:
func createReminder(in eventStore: EKEventStore) {
let reminder = EKReminder(eventStore: eventStore)
let secondReminder = EKReminder(eventStore: eventStore)
reminder.title = reminderText.text! + " " + "(Pose Beauty Salon)"
reminder.calendar =
eventStore.defaultCalendarForNewReminders()
secondReminder.title = reminderText.text! + " Tomorrow " + "(Pose Beauty Salon)"
secondReminder.calendar =
eventStore.defaultCalendarForNewReminders()
// let date = myDatePicker.date
let actualDate = myDatePicker.date
let earlyReminderDate = actualDate.addingTimeInterval(-3600*24)
//let alarm = EKAlarm(absoluteDate: date)
let alarm = EKAlarm(absoluteDate: actualDate)
let secondAlarm = EKAlarm(absoluteDate: earlyReminderDate)
reminder.addAlarm(alarm)
secondReminder.addAlarm(secondAlarm)

It seems that eventStore.defaultCalendarForNewReminders() doesn't allow for multiple alarms.
You can achieve this behaviour if you save the reminder to the calendar app instead.
I made some changes to your code to do this, hopefully this is useful:
Updated the access request
let eventStore = EKEventStore()
eventStore.requestAccess(
to: EKEntityType.event, completion: {(granted, error) in
if !granted {
print("Access to store not granted")
print(error!.localizedDescription)
} else {
print("Access granted")
self.createReminder(in: eventStore)
}
})
Create an EKEvent instead of EKReminder and open the EKEventEditViewController
func createReminder(in eventStore: EKEventStore) {
let reminder = EKEvent(eventStore: eventStore)
reminder.title = reminderText.text! + " " + "(Pose Beauty Salon)"
reminder.calendar =
eventStore.defaultCalendarForNewEvents
let date = myDatePicker.date
let alarm = EKAlarm(absoluteDate: date)
reminder.addAlarm(alarm)
let earlierDate = date.addingTimeInterval(-3600*24)
let earlierAlarm = EKAlarm(absoluteDate: earlierDate)
reminder.addAlarm(earlierAlarm)
reminder.startDate = date
reminder.endDate = date.addingTimeInterval(3600)
do {
try eventStore.save(reminder, span: .thisEvent, commit: true)
} catch let error {
print("Reminder failed with error \(error.localizedDescription)")
return
}
// Create the alert controller
let alertController = UIAlertController(title: "Reminder Created Successfully", message: "Your \(reminderText.text!) appointment reminder at Pose Beauty Salon has been successfully created in your iPhone Reminders app. Thank You!", preferredStyle: .alert)
// Create the actions
let okAction = UIAlertAction(title: "OK", style: UIAlertActionStyle.default) {
UIAlertAction in
NSLog("OK Pressed")
self.reminderText.text = ""
self.activityIndicator.stopAnimating()
}
// Add the actions
alertController.addAction(okAction)
// Present the controller
self.present(alertController, animated: true, completion: nil)
}
Added delegate method from EKEventEditViewDelegate
func eventEditViewController(_ controller: EKEventEditViewController, didCompleteWith action: EKEventEditViewAction) {
switch action
{
case .saved:
let alertController = UIAlertController(title: "Reminder Created Successfully", message: "Your \(reminderText.text!) appointment reminder at Pose Beauty Salon has been successfully created in your iPhone Reminders app. Thank You!", preferredStyle: .alert)
// Create the actions
let okAction = UIAlertAction(title: "OK", style: UIAlertActionStyle.default) {
UIAlertAction in
NSLog("OK Pressed")
self.reminderText.text = ""
self.activityIndicator.stopAnimating()
}
// Add the actions
alertController.addAction(okAction)
// Present the controller
self.present(alertController, animated: true, completion: nil)
default:
self.dismiss(animated: true, completion: nil)
}
}

You could create two separate reminders with all same data but with different dates like this:
let actualDate = myDatePicker.date
let earlyReminderDate = actualDate.addingTimeInterval(-3600*24)
