如何在iOS 10中安排本地通知(objective-c)

作者:佚名
我想使用iOS 10安排本地通知.我想知道如何做到这一点.我一直在网上看,但我一直在寻找线索,只是为了注册和处理通知.不适用于本地通知的安排.
那么,有谁知道怎么做?
解决方法
>试试吧.它已弃用但工作代码.在iOS 10.0之前使用它:
//Get all previous noti.. NSLog(@"scheduled notifications: --%@----",[[UIApplication sharedApplication] scheduledLocalNotifications]); NSDate *now = [NSDate date]; now = [now dateByAddingTimeInterval:60*60*24*7]; //7 for 7th day of the week. NSCalendar *calendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar]; [calendar setTimeZone:[NSTimeZone localTimeZone]]; NSDateComponents *components = [calendar components:NSYearCalendarUnit|NSMonthCalendarUnit|NSDayCalendarUnit|NSHourCalendarUnit|NSMinuteCalendarUnit|NSSecondCalendarUnit|NSTimeZoneCalendarUnit fromDate:now]; NSDate *SetAlarmAt = [calendar dateFromComponents:components]; UILocalNotification *localNotification = [[UILocalNotification alloc] init]; localNotification.fireDate = SetAlarmAt; NSLog(@"FIRE DATE --%@----",[SetAlarmAt description]); localNotification.alertBody =@"Alert"; localNotification.alertAction = [NSString stringWithFormat:@"My test for Weekly alarm"]; localNotification.userInfo = @{ @"alarmID":[NSString stringWithFormat:@"123"],@"SOUND_TYPE":[NSString stringWithFormat:@"hello.mp3"] }; localNotification.repeatInterval=0; //[NSCalendar currentCalendar]; [[UIApplication sharedApplication] scheduleLocalNotification:localNotification];
>对于iOS 10.0及更高版本:现在尝试使用UserNotifications框架:添加框架,并像#import一样导入.在Appdelegate Didfinishluanch方法.
UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter]; [center requestAuthorizationWithOptions:(UNAuthorizationOptionBadge | UNAuthorizationOptionSound | UNAuthorizationOptionAlert) completionHandler:^(BOOL granted,NSError * _Nullable error) { if (!error) { NSLog(@"request succeeded!"); [self testAlrt]; } }];
在你的ibaction或方法中,写下它并测试:
NSDate *now = [NSDate date]; // NSLog(@"NSDate--before:%@",now); now = [now dateByAddingTimeInterval:60*60*24*7]; NSLog(@"NSDate:%@",now); NSCalendar *calendar = [[NSCalendar alloc] initWithCalendarIdentifier:NSGregorianCalendar]; [calendar setTimeZone:[NSTimeZone localTimeZone]]; NSDateComponents *components = [calendar components:NSYearCalendarUnit|NSMonthCalendarUnit|NSDayCalendarUnit|NSHourCalendarUnit|NSMinuteCalendarUnit|NSSecondCalendarUnit|NSTimeZoneCalendarUnit fromDate:now]; NSDate *todaySehri = [calendar dateFromComponents:components]; //unused UNMutableNotificationContent *objNotificationContent = [[UNMutableNotificationContent alloc] init]; objNotificationContent.title = [NSString localizedUserNotificationStringForKey:@"Notification!" arguments:nil]; objNotificationContent.body = [NSString localizedUserNotificationStringForKey:@"This is local notification message!" arguments:nil]; objNotificationContent.sound = [UNNotificationSound defaultSound]; /// 4. update application icon badge number objNotificationContent.badge = @([[UIApplication sharedApplication] applicationIconBadgeNumber] + 1); UNCalendarNotificationTrigger *trigger = [UNCalendarNotificationTrigger triggerWithDateMatchingComponents:components repeats:NO]; UNNotificationRequest *request = [UNNotificationRequest requestWithIdentifier:@"ten" content:objNotificationContent trigger:trigger]; /// 3. schedule localNotification UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter]; [center addNotificationRequest:request withCompletionHandler:^(NSError * _Nullable error) { if (!error) { NSLog(@"Local Notification succeeded"); } else { NSLog(@"Local Notification failed"); } }];
