这可能是一个预先提出的问题，但我想知道该用什么来代替 UILocalNotification 在iOS 10中。我正在做一个应用，它的部署目标是iOS 8，那么它是否可以在iOS 10中使用 UILocalNotification?
是的，你可以使用 "UILocalNotification"。UILocalNotification旧的API在iOS 10上也能正常工作，但我们最好使用用户通知框架中的API。还有一些新功能，你只能用iOS 10用户通知框架来使用。
远程通知也是如此，更多信息。请看这里.
新功能。
我们真的很容易转换 UILocalNotification API到iOS 10User Notifications框架的API，它们真的很相似。
我在这里写了一个demo来演示如何同时使用新旧API。 iOS 10适配技巧 .
例如：
用Swift实现。
import UserNotifications
/// Notification become independent from UIKit
import UserNotifications
申请本地通知的授权
let center = UNUserNotificationCenter.current()
center.requestAuthorization(options: [.alert, .sound]) { (granted, error) in
// Enable or disable features based on authorization.
}
附表本地通知
更新申请图标徽章号码
@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实现。
导入UserNotifications
// Notifications are independent from UIKit
#import <UserNotifications/UserNotifications.h>
申请本地通知的授权
UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
[center requestAuthorizationWithOptions:(UNAuthorizationOptionBadge | UNAuthorizationOptionSound | UNAuthorizationOptionAlert)
completionHandler:^(BOOL granted, NSError * _Nullable error) {
if (!error) {
NSLog(@"request authorization succeeded!");
[self showAlert];
}
}];

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 = [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!");
}
}];
由于未捕获异常'NSInternalInconsistencyException'而终止应用程序，原因：'如果重复，时间间隔必须至少为60'。
let trigger = UNTimeIntervalNotificationTrigger.init(timeInterval: 60, repeats: true)
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
}
不要忘记添加
import UserNotifications
迅捷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
}
催促通知的代表：
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)
}
}
用Objective-C实现iOS 10的本地通知。
如果你已经编程了一段时间，我相信你一定熟悉了 UILocalNotification 类，而现在随着iOS 10的到来，你可以看到，。UILocalNotification 已被废弃。详细的实施方法请访问 本博文.
