如何在iOS 10中安排本地通知(objective-c)

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");
    }
}];
