IOS Local Notification Uilocalnotification

iOS local notifications are using OC's Uilocalnotification object, adding a notification is simple, creating a Uilocalnotification object to set some corresponding parameters on the line.

Add Local Notifications

1 //Add local push2NSDate *date = [NSDate datewithtimeintervalsincenow:Ten];3Uilocalnotification *noti =[[Uilocalnotification alloc] init];4     if(Noti) {5         //Set the time6Noti.firedate =date;7         //Setting the time zone8Noti.timezone =[Nstimezone Defaulttimezone];9         //set the recurrence intervalTenNoti.repeatinterval =Nsweekdaycalendarunit; One         //Push Sound ANoti.soundname = Uilocalnotificationdefaultsoundname;//Add a sound clip, such as @ "BEIJING.CAF" -         //content -Noti.alertbody =@"Push Content"; the         //real numbers in the red circle on icon -Noti.applicationiconbadgenumber = [[[UIApplication Sharedapplication] scheduledlocalnotifications] count] +1; -         //add userinfo for ease of use when undoing -Nsdictionary *infodic = [[Nsdictionary alloc] Initwithobjectsandkeys:@"name",@"Key", nil]; +Noti.userinfo =Infodic; -         //add push to UIApplication + [[UIApplication sharedapplication] schedulelocalnotification:noti]; A}

in the non-arc, created must learn to release. If you do not add this sentence, notice to the time, found the top of the notification bar tips where there is, then you go through the notification bar, and then you find the notification bar inside there is this hint, unless you manually clear

[Notification release];

}

Delete, modify notification

A question that prompts you in the top right corner. You triggered 5 notifications, the background is running in case, 3 has arrived, so your app in the upper right corner is now showing 3. Then you go through the notification bar or the app, the top right corner of the app should change to 0. According to the previous settings in the AddNotification, wait until the 4th notification to the next, the app in the upper right corner will show 4, the fifth to the future, will show 5, it is obvious that this is wrong. So we need to go in through the notification bar, or directly into the app after the first to set the fourth fifth notice to the next, the app in the upper right corner of the number. The two methods in this rewrite appdelegate are: Didreceivelocalnotification and applicationdidbecomeactive. Didreceiveldidreceivelocalnotification is the app that runs in the foreground, notifies the time to call the method. If the program is running in the background, the time will not go this way. Applicationdidbecomeactive is the app running in the background, the notification time, you enter from the notification bar, or directly click the app icon to enter, the way to go.

Another problem is that local notifications are cached by the system, and notifications are present regardless of whether the application is running in front of the background. But when we shut down the application and rerun it, some notifications may be added repeatedly by application logic, which is not the result we want. Therefore, the simplest way is to clear all local notifications when the program starts, and then add them again by applying logic. This adds a clear notification and resets the application hint number in the first start callback letter of the program didfinishlaunchingwithoptions.

- (BOOL)application:(uiapplication *)Application Didfinishlaunchingwithoptions:(nsdictionary *)launchoptions
{

    About notification
    Application.  =0;
[[uiapplication sharedapplication] cancelalllocalnotifications];    

　　　return YES;
}

Of course, there is also a workaround is to determine whether the ID already exists each time it is added, if there is a delete plus. Personally think this is a comparison of the method of egg pain, as well as the program when the start of emptying after the re-added good.
