IOS Uilocalnotification timed Reminders

in iOS, there are two kinds of information prompt push method, one kind is remote server push (APNS) , there is a kind of local notice uilocalnotification, today to briefly record the use of uilocalnotification, the details are as follows:

Uilocalnotification *notifity=[[uilocalnotification alloc] init];        NSDateFormatter *formattr=[[nsdateformatter alloc] init];
        Format Time        [formattr setdateformat:@ "hh:mm"];        Trigger notification time        nsdate *now=[formattr datefromstring:[nsstring stringwithformat:@ "%@", Strtimer]];        Notifity.firedate=now;        Time zone        notifity.timezone=[nstimezone Defaulttimezone];        The unit that notifies the repeating prompt, which can be weeks (nsweekdaycalendarunit) minutes (nsminutecalendarunit) seconds (nssecondcalendarunit) months (nsmonthcalendarunit) years ( Nsyearcalendarunit)

        Notifity.repeatinterval=nsdaycalendarunit;

        Notification content        [email protected] "This is a notice";        The sound notifity.soundname=uilocalnotificationdefaultsoundname to be played when the notification is triggered        ;        Perform notification registration        [[uiapplication sharedapplication] schedulelocalnotification:notifity];

If you want to carry parameter information in the notification bar, you can use the following method:

   Nsdictionary *dic = [nsdictionary dictionarywithobject:@ "name" forkey:@ "key "];       = dic;

If the software is running, you can get and process the parameter information through the callback method in Appdelegate:

-(void) Application: (UIApplication *) application didreceivelocalnotification: (uilocalnotification *) notification{    if (notification) {        nsdictionary *userinfo =  notification.userinfo;        NSString *obj = [userInfo objectforkey:@ "key"];        NSLog (@ "%@", obj);}    }

In addition, there are two ways to unregister a local notification, one is to cancel the specified notification, and the second is to cancel all registration notifications:

[[UIApplication sharedapplication] cancellocalnotification:localnotification]; [[UIApplication sharedapplication] cancelalllocalnotification];

The above is what I learned today, recorded here and shared with you, if you have any questions, please point out the joint study!
