如何在 iOS 10 (objective-c) 中安排本地通知

Question

我想使用 iOS 10 安排本地通知。我想知道如何执行此操作。我浏览了整个网络，但我一直在寻找仅用于注册和处理通知的线索。不适用于安排本地通知。

那么，有人知道怎么做吗？

按照以下步骤操作： 1. 导入 UserNotifications.framework 并转到您的 AppDelegate class.

在.h

#import <UserNotifications/UserNotifications.h>
@interface AppDelegate : UIResponder          <UIApplicationDelegate,UNUserNotificationCenterDelegate>

@end

注册推送：

#define SYSTEM_VERSION_GRATERTHAN_OR_EQUALTO(v)  ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedAscending)

现在将其添加到完成启动中：

-(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{
   [self registerForRemoteNotifications];
return YES;
}

 - (void)registerForRemoteNotifications {
  if(SYSTEM_VERSION_GRATERTHAN_OR_EQUALTO(@"10.0")){
    UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
    center.delegate = self;
    [center requestAuthorizationWithOptions:(UNAuthorizationOptionSound | UNAuthorizationOptionAlert | UNAuthorizationOptionBadge) completionHandler:^(BOOL granted, NSError * _Nullable error){
         if(!error){
             [[UIApplication sharedApplication] registerForRemoteNotifications];
         }
     }];  
}
else {
    // Code for old versions
}
}

UserNotifications 的委托方法：

  //Called when a notification is delivered to a foreground app.

 -(void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler{
NSLog(@"User Info : %@",notification.request.content.userInfo);
completionHandler(UNAuthorizationOptionSound | UNAuthorizationOptionAlert | UNAuthorizationOptionBadge);
}

 //Called to let your app know which action was selected by the user for a given notification.
 -(void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void(^)())completionHandler{
 NSLog(@"User Info : %@",response.notification.request.content.userInfo);
  completionHandler();
  }

推送通知授权：从项目目标的功能选项卡中添加推送通知授权。
正确添加推送和移动证书。希望这就是您需要的一切！

试试吧。它已弃用但有效的代码。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，然后像 #import 一样导入。在 Appdelegate Didfinishluanch 方法中。

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，编写并测试：

 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");
    }
}];
