I'm new in swift, I don't know how to implement local notification I have tried some code but it's not exactly work, so Anyone can help to implement local Notification in iOS
using swift
?
Apple does not offer a way to handle a notification that arrives when your app is closed (i.e. when the user has fully quit the application or the OS had decided to kill it while it is in the background). If this happens, the only way to handle the notification is to wait until it is opened by the user.
Use local notifications to get the user's attention. You can display an alert, play a sound, or badge your app's icon. For example, a background app could ask the system to display an alert when your app finishes a particular task. Always use local notifications to convey important information that the user wants.
The difference between the two stems from one major point: Local notifications originate from the application itself, as opposed to Push notifications which are triggered from a remote server.
Here i am sharing example,
Register for local notification,
@IBAction func registerLocal(sender: AnyObject) {
let notificationSettings = UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil)
UIApplication.sharedApplication().registerUserNotificationSettings(notificationSettings)
}
Schedule local notification,
@IBAction func scheduleLocal(sender: AnyObject) {
let notification = UILocalNotification()
notification.fireDate = NSDate(timeIntervalSinceNow: 5)
notification.alertBody = "Hey you! Yeah you! Swipe to unlock!"
notification.alertAction = "be awesome!"
notification.soundName = UILocalNotificationDefaultSoundName
notification.userInfo = ["CustomField1": "w00t"]
UIApplication.sharedApplication().scheduleLocalNotification(notification)
guard let settings = UIApplication.sharedApplication().currentUserNotificationSettings() else { return }
if settings.types == .None {
let ac = UIAlertController(title: "Can't schedule", message: "Either we don't have permission to schedule notifications, or we haven't asked yet.", preferredStyle: .Alert)
ac.addAction(UIAlertAction(title: "OK", style: .Default, handler: nil))
presentViewController(ac, animated: true, completion: nil)
return
}
}
It will fire local notification after 5 seconds
.
Hope this will help :)
There are lots of tutorials online for this, you could just Google it.
Here's a tutorial: http://jamesonquave.com/blog/local-notifications-in-ios-8-with-swift-part-1/
Also here's an example of a local notification:
let notification = UILocalNotification()
notification.fireDate = date
notification.alertBody = "Alert!"
notification.alertAction = "open"
notification.hasAction = true
notification.userInfo = ["UUID": "reminderID" ]
UIApplication.sharedApplication().scheduleLocalNotification(notification)
