cocoa touch - Ask for User Permission to Receive UILocalNotifications in iOS 8 -

-

i have set local notifications in app delegate using this: 

- (void)applicationdidenterbackground:(uiapplication *)application {     uilocalnotification *notification = [[uilocalnotification alloc]init];     [notification setalertbody:@"watch latest episode of cca-tv"];     [notification setfiredate:[nsdate datewithtimeintervalsincenow:5]];     [notification settimezone:[nstimezone defaulttimezone]];     [application setscheduledlocalnotifications:[nsarray arraywithobject:notification]]; }

when run app , quit receive error saying:

2014-06-07 11:14:16.663 cca-tv[735:149070] attempting schedule local notification {fire date = saturday, june 7, 2014 @ 11:14:21 pacific daylight time, time zone = america/los_angeles (pdt) offset -25200 (daylight), repeat interval = 0, repeat count = uilocalnotificationinfiniterepeatcount, next fire date = saturday, june 7, 2014 @ 11:14:21 pacific daylight time, user info = (null)} with alert haven't received permission user display alerts

how can necessary permission display alerts?

since ios 8 need ask user's permission show notifications app, applies both remote/push , local notifications. in swift can this,

update swift 2.0

func application(application: uiapplication, didfinishlaunchingwithoptions launchoptions: nsdictionary?) -> bool {     // override point customization after application launch.     if(uiapplication.instancesrespondtoselector(selector("registerusernotificationsettings:")))     {         let notificationcategory:uimutableusernotificationcategory = uimutableusernotificationcategory()         notificationcategory.identifier = "invite_category"         notificationcategory.setactions([replyaction], forcontext: uiusernotificationactioncontext.default)          //registerting notification.         application.registerusernotificationsettings(uiusernotificationsettings(fortypes:[.sound, .alert, .badge], categories: nil))     }     else     {        //do ios 7 stuff, pretty nothing local notifications.     }     return true }

swift 3.2

if(uiapplication.instancesrespond(to: #selector(uiapplication.registerusernotificationsettings(_:)))){      let notificationcategory:uimutableusernotificationcategory = uimutableusernotificationcategory()      notificationcategory.identifier = "invite_category"      notificationcategory.setactions([replyaction], forcontext: uiusernotificationactioncontext.default)       //registerting notification.         application.registerusernotificationsettings(uiusernotificationsettings(types:[.sound, .alert, .badge], categories: nil)) } else{         //do ios 7 stuff, pretty nothing local notifications.     }

objective c syntax similar.

- (bool)application:(uiapplication *)application didfinishlaunchingwithoptions:(nsdictionary *)launchoptions {     if ([uiapplication instancesrespondtoselector:@selector(registerusernotificationsettings:)]){         [application registerusernotificationsettings:[uiusernotificationsettings settingsfortypes:uiusernotificationtypealert|uiusernotificationtypebadge|uiusernotificationtypesound categories:nil]];     }     // override point customization after application launch.     return yes; }

to check registered notification types can use uiapplication class's method,

- (uiusernotificationsettings *)currentusernotificationsettings

so if user has said no app function should return setting without types in it.

i have written tutorial this, see here.
