如何创建本地通知ios

Question

    UILocalNotification* localNotification = [[UILocalNotificationalloc] init]; 
localNotification.alertBody = @"Your alert message";
localNotification.timeZone = [NSTimeZone defaultTimeZone];
[[UIApplication sharedApplication] scheduleLocalNotification:localNotification];

我没有收到本地通知，有人可以说如何获得本地通知。

Answer 1

localNotification.fireDate = [NSDate dateWithTimeIntervalSinceNow：60];

试试这个!!!!

Answer 2

您需要指定何时触发通知。您刚刚创建了通知但未在需要触发时设置。

例如......

localNotif.fireDate = [itemDate dateByAddingTimeIntervalInterval :-( minutesBefore * 60）];

Answer 3

如果应用程序是前台阶段，那么你不会看到那些通知。你应该对委托方法进行编码。

-(void)application:(UIApplication *)application didReceiveLocalNotification:(UILocalNotification *)notification;

Answer 4

UILocalNotification *notif = [[UILocalNotification alloc]init];
            notif.alertBody = @"Your Session is Ready";
            notif.alertAction = @"Take Now";
            notif.soundName = @"DingBell.wav";
            [notif setFireDate:[gregCalendar dateFromComponents:dateComponent]];
            notif.repeatInterval = NSWeekCalendarUnit;
            [notif setTimeZone:[NSTimeZone defaultTimeZone]];
            NSMutableDictionary *userDict = [NSMutableDictionary dictionary];
            [userDict setValue:self.stringModuleID forKey:@"kRemindMeNotificationDataKey"];
            [userDict setValue:[NSString stringWithFormat:@"alarm%d",[[setreminingDay objectAtIndex:i] intValue]] forKey:@"alarm"];
            notif.userInfo = userDict;
            [[UIApplication sharedApplication] scheduleLocalNotification:notif];
