IOS 10 Add local push (locally Notification)

Objective

The Uilocalnotification (UIKit framework) is deprecated in IOS 10, with a new usernotifications framework to push notifications, and the push notification has its own label UN (this treatment is really others), as well as a series of enhancements to the push feature (two extension and interface experience optimizations), are Apple's pro-son, so pushing this part of the feature has also become a focus in development.

This article mainly review the iOS 10 related documents, sorted out the local push notification under iOS 10, because it is code, do not do more explanation, directly read the code and comments, there is a question message discussion oh.

New push registration mechanism

Registration Notice (APPDELEGATE.M):

#import <UserNotifications/UserNotifications.h> #import "AppDelegate.h" @interface appdelegate () < Unusernotificationcenterdelegate> @end @implementation appdelegate-(BOOL) Application: (UIApplication *) Application didfinishlaunchingwithoptions: (Nsdictionary *) launchoptions {//Use Unusernotificationcenter to manage notifications UNUse    Rnotificationcenter *center = [Unusernotificationcenter currentnotificationcenter];        Listener Callback Event center.delegate = self; IOS 10 is registered with the following methods to be authorized [center Requestauthorizationwithoptions: (Unauthorizationoptionalert +                              Unauthorizationoptionsound) completionhandler:^ (BOOL Granted, Nserror * _nullable error) {                          Enable or disable features based on authorization.        }]; Gets the current notification settings, Unnotificationsettings is a read-only object, cannot be modified directly, and can only be obtained through the following methods [center Getnotificationsettingswithcompletionhandler    : ^ (unnotificationsettings * _nonnull settings) {}]; return YES;} #pragma mark-unusernotificationcenterdelegate//is processed before the notification is displayed, which means that you have the opportunity to modify the notification before displaying the notice. -(void) Usernotificationcenter: (unusernotificationcenter *) Center willpresentnotification: (unnotification *) Notification Withcompletionhandler: (void (^) (unnotificationpresentationoptions)) completionhandler{//1.

Push local notifications

Use unnotification local notification + (void) RegisterNotification: (Nsinteger) alertime{//Use Unusernotificationcenter to manage notifications U        nusernotificationcenter* Center = [Unusernotificationcenter Currentnotificationcenter];    Create a Unmutablenotificationcontent object that contains the content to be notified, and note that it is not a Unnotificationcontent object that is immutable.    unmutablenotificationcontent* content = [[Unmutablenotificationcontent alloc] init];    Content.title = [NSString localizedusernotificationstringforkey:@ "hello!" arguments:nil];    Content.body = [NSString localizedusernotificationstringforkey:@ "Hello_message_body" arguments:nil];        Content.sound = [Unnotificationsound defaultsound]; Push local push untimeintervalnotificationtrigger* after alerttime trigger = [Untimeintervalnotificationtrigger triggerWithTime    Interval:alertime Repeats:no]; unnotificationrequest* request = [unnotificationrequest requestwithidentifier:@ "Fivesecond" Content:content Trigger:        Trigger];    Add the processing after successful push! [Center Addnotificationrequest:request WITHCompletionhandler:^ (Nserror * _nullable error) {Uialertcontroller *alert = [Uialertcontroller Alertcontrollerwithti        tle:@ "Local Notification" message:@ "successfully added push" preferredstyle:uialertcontrollerstylealert];        Uialertaction *cancelaction = [uialertaction actionwithtitle:@ "Cancel" Style:uialertactionstylecancel Handler:nil];        [Alert addaction:cancelaction]; [[UIApplication Sharedapplication].keywindow.rootviewcontroller Presentviewcontroller:alert Animated:YES    Completion:nil]; }];}

Pre-local push notifications for IOS 10:
