[英]How to set a local notification to fire from a date stored in an array?
我正在制作一个提醒应用程序,到目前为止,用户是苹果公司,可以成功地提交和存储来自表单的数据,然后将其存储在数组中。当应用程序关闭时,该数组将写入文件,然后从文件中加载数据重新打开应用程序时。
我遇到了一个问题,因为我想设置通知以提醒用户在特定时间完成任务,而我无法调用存储在数组中的NSDate。 我也想使该应用程序正常工作,以便每天重复进行通知。
这是我的TableViewController:
class MedicineTableViewController: UITableViewController {
//MARK Properties
var medicines = [Medicine]()
override func viewDidLoad() {
super.viewDidLoad()
//Notifications Setup
let reminderActionOkay = UIMutableUserNotificationAction()
reminderActionOkay.identifier = "Okay"
reminderActionOkay.title = "Okay"
reminderActionOkay.activationMode = UIUserNotificationActivationMode.Background
reminderActionOkay.destructive = true
reminderActionOkay.authenticationRequired = false
let reminderActionOpen = UIMutableUserNotificationAction()
reminderActionOpen.identifier = "Open App"
reminderActionOpen.title = "Open App"
reminderActionOpen.activationMode = UIUserNotificationActivationMode.Background
reminderActionOpen.destructive = false
reminderActionOpen.authenticationRequired = true
//Put the different types of notifications into a category
let ReminderCategory = UIMutableUserNotificationCategory()
ReminderCategory.identifier = "reminderCategory"
ReminderCategory.setActions([reminderActionOpen, reminderActionOkay], forContext: UIUserNotificationActionContext.Default)
ReminderCategory.setActions([reminderActionOpen, reminderActionOkay], forContext: UIUserNotificationActionContext.Minimal)
//MARK: Notification Schedule
func scheduleLocalNotification() {
let localNotificationtime1 = UILocalNotification()
localNotificationtime1.alertTitle = "Take", medicines.name
localNotificationtime1.alertBody = "It is time to take", medicines.name
localNotificationtime1.alertAction = "Show Details"
localNotificationtime1.fireDate = medicine.time1 // 1 Day repeating
localNotificationtime1.timeZone = NSTimeZone.defaultTimeZone()
localNotificationtime1.soundName = UILocalNotificationDefaultSoundName
localNotificationtime1.applicationIconBadgeNumber = 1
localNotificationtime1.category = "reminderCategory"
UIApplication.sharedApplication().scheduleLocalNotification(localNotificationtime1)
let localNotificationtime2 = UILocalNotification()
localNotificationtime2.alertTitle = "Take", medicines.name
localNotificationtime2.alertBody = "It is time to take", medicines.name
localNotificationtime2.alertAction = "Show Details"
localNotificationtime2.fireDate = medicines.time2
localNotificationtime2.timeZone = NSTimeZone.defaultTimeZone()
localNotificationtime2.soundName = UILocalNotificationDefaultSoundName
localNotificationtime2.applicationIconBadgeNumber = 1
localNotificationtime2.category = "reminderCategory"
UIApplication.sharedApplication().scheduleLocalNotification(localNotificationtime2)
let localNotificationtime3 = UILocalNotification()
localNotificationtime3.alertTitle = "Take", medicines.name
localNotificationtime3.alertBody = "It is time to take", medicines.name
localNotificationtime3.alertAction = "Show Details"
localNotificationtime3.fireDate = medicines.time3
localNotificationtime3.timeZone = NSTimeZone.defaultTimeZone()
localNotificationtime3.soundName = UILocalNotificationDefaultSoundName
localNotificationtime3.applicationIconBadgeNumber = 1
localNotificationtime3.category = "reminderCategory"
UIApplication.sharedApplication().scheduleLocalNotification(localNotificationtime3)
let localNotificationtime4 = UILocalNotification()
localNotificationtime4.alertTitle = "Take", medicines.name
localNotificationtime4.alertBody = "It is time to take", medicines.name
localNotificationtime4.alertAction = "Show Details"
localNotificationtime4.fireDate = medicines.time4
localNotificationtime4.timeZone = NSTimeZone.defaultTimeZone()
localNotificationtime4.soundName = UILocalNotificationDefaultSoundName
localNotificationtime4.applicationIconBadgeNumber = 1
localNotificationtime4.category = "reminderCategory"
UIApplication.sharedApplication().scheduleLocalNotification(localNotificationtime4)
let localNotificationtime5 = UILocalNotification()
localNotificationtime5.alertTitle = "Take", medicines.name
localNotificationtime5.alertBody = "It is time to take", medicines.name
localNotificationtime5.alertAction = "Show Details"
localNotificationtime5.fireDate = medicines.time5
localNotificationtime5.timeZone = NSTimeZone.defaultTimeZone()
localNotificationtime5.soundName = UILocalNotificationDefaultSoundName
localNotificationtime5.applicationIconBadgeNumber = 1
localNotificationtime5.category = "reminderCategory"
UIApplication.sharedApplication().scheduleLocalNotification(localNotificationtime5)
}
}
这是我的AppDelegate:
import UIKit
import CoreData
@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {
var window: UIWindow?
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
let settings = UIUserNotificationSettings(forTypes: [.Alert, .Badge], categories: nil)
UIApplication.sharedApplication().registerUserNotificationSettings(settings)
// Override point for customization after application launch.
return true
}
func application(application: UIApplication, didReceiveLocalNotification notification: UILocalNotification) {
// Point for handling the local notification when the app is open.
// Showing reminder details in an alertview
UIAlertView(title: notification.alertTitle, message: notification.alertBody, delegate: nil, cancelButtonTitle: "OK").show()
}
func application(application: UIApplication, handleActionWithIdentifier identifier: String?, forLocalNotification notification: UILocalNotification, completionHandler: () -> Void) {
// Point for handling the local notification Action. Provided alongside creating the notification.
if identifier == "ShowDetails" {
// Showing reminder details in an alertview
UIAlertView(title: notification.alertTitle, message: notification.alertBody, delegate: nil, cancelButtonTitle: "OK").show()
} else if identifier == "Okay" {
} else if identifier == "Open App" {
//Launches app when open app button pressed
UIApplicationState.Active
}
completionHandler()
}
这是我的数据模型:
import UIKit
class Medicine : NSObject, NSCoding {
var name: String
var time1: NSDate
var time2: NSDate
var time3: NSDate
var time4: NSDate
var time5: NSDate
init?(name: String, time1: NSDate, time2: NSDate, time3: NSDate, time4: NSDate, time5: NSDate) {
self.name = name
self.time1 = time1
self.time2 = time2
self.time3 = time3
self.time4 = time4
self.time5 = time5
super.init()
if name.isEmpty {
return nil
}
}
由于不知道如何将字符串和数组中存储的信息链接在一起,因此警报主体和标题也出现错误。
顺便说一句,这是自从零开始学习语言以来我的第一个快速项目,所以如果我是个白痴,请对我轻松一点。 :(
更改这些行
localNotificationtime1.alertTitle = "Take", medicines.name
localNotificationtime1.alertBody = "It is time to take", medicines.name
对这些
localNotificationtime1.alertTitle = "Take \(medicines.name)"
localNotificationtime1.alertBody = "It is time to take \(medicines.name)"
要添加时间,请添加以下代码
localNotificationtime1.fireDate = NSDate(time1)
