deadline picker for post swift - ios

Question

i have text Feld and I post text
and I need it to be in deadline
now when I post it will be post not wait to the time then post
I hope you understand me .
SO what I should do?
this was the code I wrote
import Foundation
struct TodoItem {
var title: String
var deadline: Date
var UUID: String
init(deadline: Date, title: String, UUID: String) {
self.deadline = deadline
self.title = title
self.UUID = UUID
}
var isOverdue: Bool {
return (Date().compare(self.deadline) == ComparisonResult.orderedDescending) // deadline is earlier than current date
}
}
2-this is next code i add it all to under stand my vision
so this is to post go next view and more
import Foundation
import UIKit
class TodoList {
class var sharedInstance : TodoList {
struct Static {
static let instance: TodoList = TodoList()
}
return Static.instance
}
fileprivate let ITEMS_KEY = "todoItems"
func allItems() -> [TodoItem] {
let todoDictionary = UserDefaults.standard.dictionary(forKey: ITEMS_KEY) ?? [:]
let items = Array(todoDictionary.values)
return items.map({
let item = $0 as! [String:AnyObject]
return TodoItem(deadline: item["deadline"] as! Date, title: item["title"] as! String, UUID: item["UUID"] as! String!)
}).sorted(by: {(left: TodoItem, right:TodoItem) -> Bool in
(left.deadline.compare(right.deadline) == .orderedAscending)
})
}
func addItem(_ item: TodoItem) {
// persist a representation of this todo item in NSUserDefaults
var todoDictionary = UserDefaults.standard.dictionary(forKey: ITEMS_KEY) ?? Dictionary() // if todoItems hasn't been set in user defaults, initialize todoDictionary to an empty dictionary using nil-coalescing operator (??)
todoDictionary[item.UUID] = ["deadline": item.deadline, "title": item.title, "UUID": item.UUID] // store NSData representation of todo item in dictionary with UUID as key
UserDefaults.standard.set(todoDictionary, forKey: ITEMS_KEY) // save/overwrite todo item list
// create a corresponding local notification
let notification = UILocalNotification()
notification.alertBody = "Todo Item \"\(item.title)\" Is Overdue" // text that will be displayed in the notification
notification.alertAction = "open" // text that is displayed after "slide to..." on the lock screen - defaults to "slide to view"
notification.fireDate = item.deadline as Date // todo item due date (when notification will be fired)
notification.soundName = UILocalNotificationDefaultSoundName // play default sound
notification.userInfo = ["title": item.title, "UUID": item.UUID] // assign a unique identifier to the notification so that we can retrieve it later
UIApplication.shared.scheduleLocalNotification(notification)
var inputValue = [index]
let request = NSMutableURLRequest(url: URL(string: "http://www.alhumaidi.net/hamsat1.php")!)
request.httpMethod = "POST"
let postString = "&b=\(item.title)"
request.httpBody = postString.data(using: String.Encoding.utf8)
let task = URLSession.shared.dataTask(with: request as URLRequest) {
data, response, error in
if error != nil {
print("error=\(error)")
return
}
print("response = \(response)")
let responseString = NSString(data: data!, encoding: String.Encoding.utf8.rawValue)
print("responseString = \(responseString)")};
task.resume()
}
func removeItem(_ item: TodoItem) {
let scheduledNotifications: [UILocalNotification]? = UIApplication.shared.scheduledLocalNotifications
guard scheduledNotifications != nil else {return} // Nothing to remove, so return
for notification in scheduledNotifications! { // loop through notifications...
if (notification.userInfo!["UUID"] as! String == item.UUID) { // ...and cancel the notification that corresponds to this TodoItem instance (matched by UUID)
UIApplication.shared.cancelLocalNotification(notification) // there should be a maximum of one match on UUID
break
}
}
if var todoItems = UserDefaults.standard.dictionary(forKey: ITEMS_KEY) {
todoItems.removeValue(forKey: item.UUID)
UserDefaults.standard.set(todoItems, forKey: ITEMS_KEY) // save/overwrite todo item list
}
}
}
now when I add new post it go to next view but it post not wait the time to post.

return cell
}

}
override func tableView(_ tableView: UITableView, commit editingStyle: UITableViewCellEditingStyle, forRowAt indexPath: IndexPath) {
if editingStyle == .delete { // the only editing style we'll support
// Delete the row from the data source
let item = todoItems.remove(at: (indexPath as NSIndexPath).row) // remove TodoItem from notifications array, assign removed item to 'item'
tableView.deleteRows(at: [indexPath], with: .fade)
TodoList.sharedInstance.removeItem(item) // delete backing property list entry and unschedule local notification (if it still exists)
self.navigationItem.rightBarButtonItem!.isEnabled = true // we definitely have under 64 notifications scheduled now, make sure 'add' button is enabled
}
}
}
than you all.
