I’m new to iOS development. My question is how do you remove a local notification using a uuidString as the identifier since it creates a new identifier every time a new notification is created. I know that in order to remove pending notifications you can use methods to remove them all or to remove them with a hard coded identifier String such as UNUserNotificationCenter.current().removePendingNotificationRequests(withIdentifiers: “identifier”), but how can you remove a individual pending notification using uuidString.
Here is a sample of my code where i create the notifications and where i would like to delete it:
public var complationL: ((String,String,String)->Void)?
@objc func saveButtonPressed(){
if let titleText = titleTextFieldL.text, !titleText.isEmpty,
let bodyText = bodyViewField.text, !bodyText.isEmpty,
let searchText = locationSearchBar.text, !searchText.isEmpty{
complationL?(titleText,bodyText,"\(segmentedControl.titleForSegment(at: segmentedControl.selectedSegmentIndex)!): \(searchText)")
if segmentedControl.selectedSegmentIndex == 0{
if let center = defaults.coordinate(forKey: "NCoordinates"){
let content = UNMutableNotificationContent()
content.title = titleText
content.body = bodyText
content.sound = .default
let uuidStringEntry = UUID().uuidString
let region = CLCircularRegion(center: center, radius: 300.0, identifier: uuidStringEntry)
region.notifyOnEntry = true
region.notifyOnExit = false
let trigger = UNLocationNotificationTrigger(region: region, repeats: false)
let notificationRequest = UNNotificationRequest(identifier: uuidStringEntry, content: content, trigger: trigger)
UNUserNotificationCenter.current().add(notificationRequest) { error in
if error != nil{
print("Error providing Arriving notification")
}else{
print("Succesfully provided Arriving notification")
}
}
}
}else if segmentedControl.selectedSegmentIndex == 1{
if let center = defaults.coordinate(forKey: "NCoordinates"){
let content = UNMutableNotificationContent()
content.title = titleText
content.body = bodyText
content.sound = .default
let uuidStringExit = UUID().uuidString
let region = CLCircularRegion(center: center, radius: 300.0, identifier: uuidStringExit)
region.notifyOnEntry = false
region.notifyOnExit = true
let trigger = UNLocationNotificationTrigger(region: region, repeats: false)
let notificationRequest = UNNotificationRequest(identifier: uuidStringExit, content: content, trigger: trigger)
UNUserNotificationCenter.current().add(notificationRequest) { error in
if error != nil{
print("Error providing Leaving notification")
}else{
print("Succesfully provided Leaving notification")
}
}
}
}
}
}
}
func tableView(_ tableView: UITableView, editingStyleForRowAt indexPath: IndexPath) -> UITableViewCell.EditingStyle {
return .delete
}
func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCell.EditingStyle, forRowAt indexPath: IndexPath) {
if editingStyle == .delete{
tableView.beginUpdates()
context.delete(reminder[indexPath.row])
reminder.remove(at: indexPath.row)
tableView.deleteRows(at: [indexPath], with: .fade)
tableView.endUpdates()
saveData()
}
}
