It may be a question in advance but I wonder what to use instead of UILocalNotification in iOS 10. I am working on an app which has deployment target iOS 8 so will it be ok to use UILocalNotification?

解决方案

Yes, you can use UILocalNotification, old APIs also works fine with iOS 10, but we had better use the APIs in the User Notifications framework instead. There are also some new features, you can only use with iOS 10 User Notifications framework.

This also happens to Remote Notification, for more information: Here.

New Features:

Now you can either present alert, sound or increase badge while the app is in foreground too with iOS 10
Now you can handle all event in one place when user tapped (or slided) the action button, even while the app has already been killed.
Support 3D touch instead of sliding gesture.
Now you can remove specific local notifications with just one line of code.
Support Rich Notification with custom UI.

It is really easy for us to convert UILocalNotification APIs to iOS 10 User Notifications framework APIs, they are really similar.

I wrote a demo here to show how to use new and old APIs at the same time: iOS 10 Adaptation Tips .

For example,

With Swift implementation:

import UserNotifications

///    Notification become independent from UIKit
import UserNotifications

request authorization for localNotification

    let center = UNUserNotificationCenter.current()center.requestAuthorization(options: [.alert, .sound]) { (granted, error) in// Enable or disable features based on authorization.}

schedule localNotification

update application icon badge number

@IBAction  func triggerNotification(){let content = UNMutableNotificationContent()content.title = NSString.localizedUserNotificationString(forKey: "Elon said:", arguments: nil)content.body = NSString.localizedUserNotificationString(forKey: "Hello Tom！Get up, let's play with Jerry!", arguments: nil)content.sound = UNNotificationSound.default()content.badge = UIApplication.shared().applicationIconBadgeNumber + 1;content.categoryIdentifier = "com.elonchan.localNotification"// Deliver the notification in 60 seconds.let trigger = UNTimeIntervalNotificationTrigger.init(timeInterval: 60.0, repeats: true)let request = UNNotificationRequest.init(identifier: "FiveSecond", content: content, trigger: trigger)// Schedule the notification.let center = UNUserNotificationCenter.current()center.add(request)
}@IBAction func stopNotification(_ sender: AnyObject) {let center = UNUserNotificationCenter.current()center.removeAllPendingNotificationRequests()// or you can remove specifical notification:// center.removePendingNotificationRequests(withIdentifiers: ["FiveSecond"])
}

Objective-C implementation:

import UserNotifications

// Notifications are independent from UIKit
#import <UserNotifications/UserNotifications.h>

request authorization for localNotification

UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
[center requestAuthorizationWithOptions:(UNAuthorizationOptionBadge | UNAuthorizationOptionSound | UNAuthorizationOptionAlert)completionHandler:^(BOOL granted, NSError * _Nullable error) {if (!error) {NSLog(@"request authorization succeeded!");[self showAlert];}}];

schedule localNotification

update application icon badge number

UNMutableNotificationContent *content = [[UNMutableNotificationContent alloc] init];
content.title = [NSString localizedUserNotificationStringForKey:@"Elon said:"arguments:nil];
content.body = [NSString localizedUserNotificationStringForKey:@"Hello Tom！Get up, let's play with Jerry!"arguments:nil];
content.sound = [UNNotificationSound defaultSound];// 4. update application icon badge number
content.badge = [NSNumber numberWithInteger:([UIApplication sharedApplication].applicationIconBadgeNumber + 1)];
// Deliver the notification in five seconds.
UNTimeIntervalNotificationTrigger *trigger = [UNTimeIntervalNotificationTriggertriggerWithTimeInterval:5.frepeats:NO];
UNNotificationRequest *request = [UNNotificationRequest requestWithIdentifier:@"FiveSecond"content:contenttrigger:trigger];
/// 3. schedule localNotification
UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
[center addNotificationRequest:request withCompletionHandler:^(NSError * _Nullable error) {if (!error) {NSLog(@"add NotificationRequest succeeded!");}
}];

Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'time interval must be at least 60 if repeating'

这可能是一个预先提出的问题，但我想知道在iOS 10中使用什么代替UILocalNotification.我正在开发具有部署目标iOS 8的应用程序，因此可以使用UILocalNotification吗?

解决方案

是的，您可以使用UILocalNotification，旧的API也可以在iOS 10上正常工作，但是我们最好在用户通知框架中使用这些API.还有一些新功能，您只能与iOS 10用户通知框架一起使用.

"远程通知"也会发生这种情况，以获取更多信息:此处.

新功能:

现在，在iOS 10中，您也可以在应用程序处于前台状态时显示警报，声音或增加徽章
现在，即使用户已经杀死应用程序，只要轻按(或滑动)操作按钮，您就可以在一个地方处理所有事件.
支持3D触摸而不是滑动手势.
现在您只需一行代码即可删除特定的本地通知.
通过自定义UI支持Rich Notification.

我们很容易将UILocalNotification API转换为iOS 10 用户通知框架API，它们确实很相似.

我在此处编写了一个演示，以演示如何同时使用新旧API: iOS 10适应技巧 .

例如，

使用Swift实现:

导入用户通知

///    Notification become independent from UIKit
import UserNotifications

localNotification的请求授权

    let center = UNUserNotificationCenter.current()center.requestAuthorization(options: [.alert, .sound]) { (granted, error) in// Enable or disable features based on authorization.}

}@IBAction func stopNotification(_ sender: AnyObject) {let center = UNUserNotificationCenter.current()center.removeAllPendingNotificationRequests()// or you can remove specifical notification:// center.removePendingNotificationRequests(withIdentifiers: ["FiveSecond"])
}

Objective-C实现:

导入用户通知

// Notifications are independent from UIKit
#import <UserNotifications/UserNotifications.h>

localNotification的请求授权

UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
[center requestAuthorizationWithOptions:(UNAuthorizationOptionBadge | UNAuthorizationOptionSound | UNAuthorizationOptionAlert)completionHandler:^(BOOL granted, NSError * _Nullable error) {if (!error) {NSLog(@"request authorization succeeded!");[self showAlert];}}];

content.sound = [UNNotificationSound defaultSound];// 4. update application icon badge number
content.badge = [NSNumber numberWithInteger:([UIApplication sharedApplication].applicationIconBadgeNumber + 1)];
// Deliver the notification in five seconds.
UNTimeIntervalNotificationTrigger *trigger = [UNTimeIntervalNotificationTriggertriggerWithTimeInterval:5.frepeats:NO];
UNNotificationRequest *request = [UNNotificationRequest requestWithIdentifier:@"FiveSecond"content:contenttrigger:trigger];
/// 3. schedule localNotification
UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
[center addNotificationRequest:request withCompletionHandler:^(NSError * _Nullable error) {if (!error) {NSLog(@"add NotificationRequest succeeded!");}
}];

由于未捕获的异常"NSInternalInconsistencyException"而终止应用程序，原因:"如果重复，则时间间隔必须至少为60"

let trigger = UNTimeIntervalNotificationTrigger.init(timeInterval: 60, repeats: true)
