Question

我想在我的项目中添加本地通知。在DetailViewController中，我有两个标有date和hour的标签。

是否可以根据此date和hour添加通知？如果是的话，你能解释一下如何设置吗？

代码：

DetailViewController：

import UIKit

class DetailViewController: UIViewController, UITableViewDataSource,      UITableViewDelegate {

// MARK: - Outlet

@IBOutlet var imageProfilo: UIImageView!
@IBOutlet var labelNome: UILabel!
@IBOutlet var pillsTable: UITableView!

// MARK: - Variabili
var profilo: ProfiloModel!

// MARK: - Metodi standard del controller

override func viewDidLoad() {
    super.viewDidLoad()

    pillsTable.dataSource = self
    pillsTable.delegate = self

    imageProfilo.layer.cornerRadius = 30


    DataManager.sharedInstance.detail = self

    if let test = profilo {
    //title = profilo!.nome
    labelNome.text = profilo!.nome
    imageProfilo.image = profilo!.immagine

        if profilo!.immagine.size.width > profilo!.immagine.size.height {
            imageProfilo.image = UIImage(CGImage: profilo!.immagine.CGImage, scale: 1.0, orientation: UIImageOrientation.Right)
        } else {
            imageProfilo.image = profilo!.immagine
        }


    } else {

        if !DataManager.sharedInstance.storage.isEmpty {
            profilo = DataManager.sharedInstance.storage[0]
            //title = profiloSos.nome
            labelNome.text = profilo.nome
            imageProfilo.image = profilo.immagine


            if profilo.immagine.size.width > profilo.immagine.size.height {
                imageProfilo.image = UIImage(CGImage: profilo.immagine.CGImage, scale: 1.0, orientation: UIImageOrientation.Right)
            } else {
                imageProfilo.image = profilo.immagine
            }

        } else {
            return
        }

    }


}

override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}

// MARK: UITableView 
 func numberOfSectionsInTableView(tableView: UITableView) -> Int {
    return 1
}

 func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return profilo.therapyArra.count
}

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as! PillsCell

    var terapia = profilo.therapyArra[indexPath.row]

    cell.nomeMedicina.text = terapia.nomeMedicina
    cell.data.text = terapia.data
    cell.ora.text = terapia.ora
    cell.dosaggio.text = terapia.dosaggio

    return cell
}


// MARK: - Azioni


// MARK: - Metodi


// MARK: - Navigazione
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {

    if segue.identifier == "terapia" {
        var cell = sender as! UITableViewCell
        if let indexPath = self.pillsTable.indexPathForRowAtPoint(cell.center) {
            var controller = segue.destinationViewController as! PillsViewController
            controller.therapy = profilo.therapyArra[indexPath.row]
        }

    } else if segue.identifier == "addtherapy" {

        var controller = segue.destinationViewController as! AddPillsController
        controller.profilo = profilo

    }
}

}'

PillsCell：

'import UIKit

class PillsCell: UITableViewCell {



@IBOutlet var nomeMedicina: UILabel!
@IBOutlet var ora: UILabel!
@IBOutlet var data: UILabel!
@IBOutlet var dosaggio: UILabel!

override func awakeFromNib() {
    super.awakeFromNib()
    // Initialization code
}

override func setSelected(selected: Bool, animated: Bool) {
    super.setSelected(selected, animated: animated)

    // Configure the view for the selected state
}

}

PillsModel：

import UIKit

 class PillsModel: NSObject, NSCoding {

var nomeMedicina :String!
var data :String!
var ora :String!
var dosaggio :String!

init(nomeMedicinaIn:String, dataIn:String, oraIn:String, dosaggioIn:String) {
    nomeMedicina = nomeMedicinaIn
    ora = oraIn
    data = dataIn
    dosaggio = dosaggioIn
}

internal required init(coder aDecoder: NSCoder) {
    self.nomeMedicina = aDecoder.decodeObjectForKey("nomeMedicina") as! String
    self.ora = aDecoder.decodeObjectForKey("ora") as! String
    self.data = aDecoder.decodeObjectForKey("data") as! String
    self.dosaggio = aDecoder.decodeObjectForKey("dosaggio") as! String

}

func encodeWithCoder(encoder: NSCoder) {
    encoder.encodeObject(self.nomeMedicina, forKey: "nomeMedicina")
    encoder.encodeObject(self.ora, forKey: "ora")
    encoder.encodeObject(self.data, forKey: "data")
    encoder.encodeObject(self.dosaggio, forKey: "dosaggio")


}

}

AddPillsController：

import UIKit

class AddPillsController: UIViewController, UITextFieldDelegate, CameraManagerDelegate {

@IBOutlet var fieldNomeMedicina: UITextField!
@IBOutlet var fieldData: UITextField!
@IBOutlet var fieldOra: UITextField!
@IBOutlet var fieldDosaggio: UITextField!

var profilo: ProfiloModel!

override func viewDidLoad() {
    super.viewDidLoad()


    fieldNomeMedicina.delegate = self
    fieldData.delegate = self
    fieldOra.delegate = self



    // Vista accessoria per la tastiera
    var keyboardToolbar = UIToolbar(frame: CGRectMake(0, 0, self.view.bounds.size.width, 44))
    keyboardToolbar.barStyle = UIBarStyle.BlackTranslucent
    keyboardToolbar.backgroundColor = UIColor.redColor()
    keyboardToolbar.tintColor = UIColor.whiteColor()
    var flex = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.FlexibleSpace, target: nil, action: nil)
    var save = UIBarButtonItem(title: "Fatto", style: UIBarButtonItemStyle.Done, target: fieldDosaggio, action: "resignFirstResponder")
    keyboardToolbar.setItems([flex, save], animated: false)
    fieldDosaggio.inputAccessoryView = keyboardToolbar
}


func textFieldShouldReturn(textField: UITextField) -> Bool {
    textField.resignFirstResponder() // chiudere la tastiera nei campi di testo
    return true
}


override func didReceiveMemoryWarning() {
    super.didReceiveMemoryWarning()
    // Dispose of any resources that can be recreated.
}



@IBAction func annulla(sender: UIButton) {
    dismissViewControllerAnimated(true, completion: nil) // chiude una modal
}


@IBAction func salva(sender: UIButton) {
    if fieldNomeMedicina.text.isEmpty &&
        fieldData.text.isEmpty &&
        fieldOra.text.isEmpty &&
        fieldDosaggio.text.isEmpty{
            //alertView che avverte l'utente che tutti i campi sono obbligatori
            return
    }

    var therapy = PillsModel(nomeMedicinaIn: fieldNomeMedicina.text,
        dataIn: fieldData.text,
        oraIn: fieldOra.text,
        dosaggioIn : fieldDosaggio.text)

    profilo.therapyArra.append(therapy)
    DataManager.sharedInstance.salvaArray()
    DataManager.sharedInstance.detail.pillsTable.reloadData()

    dismissViewControllerAnimated(true, completion: nil)
}

您应该使用UILocalNotification。使用您的日期和时间创建NSDate对象，然后设置如下通知：

let notification = UILocalNotification()
notification.fireDate = ... // Add your date here
notification.alertBody = "Alert alert alert!!!"
UIApplication.sharedApplication().scheduleLocalNotification(notification)

通过覆盖didReceiveLocalNotification方法处理AppDelegate中的通知：

func application(application: UIApplication, didReceiveLocalNotification notification: UILocalNotification) {
    println(notification.alertBody);  // "Alert alert alert!!!"
}

如何添加通知？
