iOS 10 中弃用了 UILocalNotification

Question

这可能是一个提前的问题，但我想知道在 iOS 10 中使用什么代替 UILocalNotification。我正在开发一个具有部署目标 iOS 8 的应用程序，所以使用 UILocalNotification 可以吗？

Answer 1

是的，您可以使用 UILocalNotification，旧的 API 也适用于 iOS 10，但我们最好改用用户通知框架中的 API。还有一些新功能，您只能使用 iOS 10 User Notifications 框架。

这也发生在远程通知中，有关更多信息：。

新功能：

现在您也可以使用 iOS 10
现在您可以在用户点击（或滑动）操作按钮时在一处处理所有事件，即使应用已被终止。
支持 3D 触摸而不是滑动手势。
现在只需一行代码即可删除特定的本地通知。
支持自定义丰富的通知 UI。

我们很容易将UILocalNotification API 转换为iOS 10 User Notifications framework API，它们真的很相似。

我在这里写了一个演示来展示如何同时使用新旧API：iOS 10 Adaptation Tips .

例如，

使用 Swift 实现：

导入用户通知

///    Notification become independent from UIKit
import UserNotifications

请求 localNotification 授权

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

@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 实施：

导入用户通知

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

请求 localNotification 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.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 = [UNTimeIntervalNotificationTrigger
                                            triggerWithTimeInterval:5.f
                                            repeats:NO];
UNNotificationRequest *request = [UNNotificationRequest requestWithIdentifier:@"FiveSecond"
                                                                    content:content
                                                                    trigger:trigger];
/// 3. schedule localNotification
UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
[center addNotificationRequest:request withCompletionHandler:^(NSError * _Nullable error) {
    if (!error) {
        NSLog(@"add NotificationRequest succeeded!");
    }
}];

苹果又做了一次，正确的实现是： AppDelegate.swift

if #available(iOS 10.0, *) {
        let center = UNUserNotificationCenter.currentNotificationCenter()
        center.requestAuthorizationWithOptions([.Alert, .Sound]) { (granted, error) in
            // Enable or disable features based on authorization.
        }
    } else {
        // Fallback on earlier versions
    }

别忘了添加

import UserNotifications

Answer 3

iOS 10 在 Objective-C 的本地通知。

如果您已经编程了一段时间，我相信您对 UILocalNotification class 很熟悉，现在随着 iOS 10 的到来，您可以看到 UILocalNotification 已弃用。如需详细实施，请访问 this blog post.

swift 4

if #available(iOS 10.0, *) {
        let center = UNUserNotificationCenter.current()
        center.requestAuthorization(options: [.alert, .badge, .sound])  { (granted, error) in
            // Enable or disable features based on authorization.
        }
    } else {
        // REGISTER FOR PUSH NOTIFICATIONS
        let notifTypes:UIUserNotificationType  = [.alert, .badge, .sound]
        let settings = UIUserNotificationSettings(types: notifTypes, categories: nil)
        application.registerUserNotificationSettings(settings)
        application.registerForRemoteNotifications()
        application.applicationIconBadgeNumber = 0

    }

马克：- 推送通知代表

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
    let installation = PFInstallation.current()
    installation?.setDeviceTokenFrom(deviceToken)
    installation?.saveInBackground(block: { (succ, error) in
        if error == nil {
            print("DEVICE TOKEN REGISTERED!")
        } else {
            print("\(error!.localizedDescription)")
        }
    })
}

func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
    print("application:didFailToRegisterForRemoteNotificationsWithError: %@", error)
}

func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any]) {
    print("\(userInfo)")

    // PFPush.handle(userInfo)
    if application.applicationState == .inactive {
        PFAnalytics.trackAppOpenedWithRemoteNotificationPayload(inBackground: userInfo, block: nil)
    }
}
