swift - How to put notifications on iOS application to repeat every one (1) hour? -

-

i tried put notifications in app, supposed repeat every 1 hour repeat unregulated, clear, repeats 30min 1 hour long time etc.. code used in "appdelegate.swift":

class appdelegate: uiresponder, uiapplicationdelegate {  var window: uiwindow?  func application(application: uiapplication, didfinishlaunchingwithoptions launchoptions: [nsobject: anyobject]?) -> bool {     // override point customization after application launch.      //notification repeat application.registerusernotificationsettings(uiusernotificationsettings(fortypes: uiusernotificationtype.alert | uiusernotificationtype.badge | uiusernotificationtype.sound, categories: nil))       return true   }

and code used in "viewcontroller.swift":

//notification repeat var time = 1    override func viewdidload() {     super.viewdidload()     // additional setup after loading view, typically nib.       //notification repeat     var timer = nstimer.scheduledtimerwithtimeinterval(3600.0, target: self, selector: selector("activatenotifications"), userinfo: nil, repeats: true) }    //notification repeat func activatenotifications() {      time -= 1      if (time <= 0){            var activatenotifications = uilocalnotification()          activatenotifications.alertaction = “hey"         activatenotifications.alertbody = “hello world!"           activatenotifications.firedate = nsdate(timeintervalsincenow: 0)           uiapplication.sharedapplication().schedulelocalnotification(activatenotifications)     } }

can me, made mistake ?

you don't need timer @ all. uilocalnotification class has property entitled repeatinterval that, can expect, set interval @ notification repeated.

according this, can schedule local notifications repeated every hour in following way:

func viewdidload() {     super.viewdidload()      var notification = uilocalnotification()     notification.alertbody = "..." // text displayed in notification             notification.firedate = nsdate()  // right (when notification fired)     notification.soundname = uilocalnotificationdefaultsoundname // play default sound     notification.repeatinterval = nscalendarunit.calendarunithour // line defines interval @ notification repeated     uiapplication.sharedapplication().schedulelocalnotification(notification) }

note: sure execute code when launch notification once, since schedules different notification every time executed. better understanding of local notifications, can read local notifications in ios 8 swift (part 1) , local notifications in ios 8 swift (part 2).
