How to schedule a local notification in iOS 10 (objective-c)
提问by Developer
I'd like to schedule local notifications using iOS 10. I'd like to know how to do this. I've looked all around the web, but I keep finding clues only for registering and handeling the notifications. Not for the scheduling of a local notification.
我想使用 iOS 10 安排本地通知。我想知道如何执行此操作。我已经环顾了整个网络，但我一直在寻找仅用于注册和处理通知的线索。不适用于本地通知的调度。
So, does anyone know how to do this?
那么，有谁知道如何做到这一点？

Try it. Its deprecated but working code. Use it for Before iOS 10.0 :
//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];For iOS 10.0 and later: Now try with UserNotifications framework: Add the framework, and import like #import . In Appdelegate Didfinishluanch method.
UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter]; [center requestAuthorizationWithOptions:(UNAuthorizationOptionBadge | UNAuthorizationOptionSound | UNAuthorizationOptionAlert) completionHandler:^(BOOL granted, NSError * _Nullable error) { if (!error) { NSLog(@"request succeeded!"); [self testAlrt]; } }];
尝试一下。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]; } }];
In your ibaction or method, write it and test:
在您的 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");
}
}];

Follow the step: 1. Import UserNotifications.framework and go to your AppDelegate class.
请按照以下步骤操作： 1. 导入 UserNotifications.framework 并转到您的 AppDelegate 类。
In .h
在.h
#import <UserNotifications/UserNotifications.h>
@interface AppDelegate : UIResponder <UIApplicationDelegate,UNUserNotificationCenterDelegate>
@end
Register for push :
#define SYSTEM_VERSION_GRATERTHAN_OR_EQUALTO(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedAscending)
注册推送：
#define SYSTEM_VERSION_GRATERTHAN_OR_EQUALTO(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedAscending)
Now add this in did finish launching :
现在添加这个确实完成启动：
-(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
}
}
Delegate methods for UserNotifications :
//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(); }Push Notifications Entitlements : From project target's Capabilities tab and add Push Notifications Entitlements.
Add push and mobile certificate properly. Hope this is everything you need!
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(); }推送通知权利：从项目目标的功能选项卡并添加推送通知权利。
正确添加推送和移动证书。希望这是您需要的一切！
