didReceiveRemoteNotification
是 iOS 应用程序中的一个方法,用于处理远程通知(推送通知)。当应用程序在后台运行或未启动时,接收到远程通知后,系统会调用这个方法来通知应用程序。
didReceiveRemoteNotification
原因可能包括:
didReceiveRemoteNotification
方法。在应用启动时,请求用户授权接收通知:
import UserNotifications
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .badge, .sound]) { granted, error in
if granted {
print("Notification authorization granted")
} else {
print("Notification authorization denied")
}
}
return true
}
确保 Info.plist 文件中包含以下内容:
<key>NSLocalNotificationUsageDescription</key>
<string>我们需要使用通知来提醒您重要信息</string>
<key>NSMicrophoneUsageDescription</key>
<string>我们需要使用麦克风来录制音频</string>
didReceiveRemoteNotification
方法在 AppDelegate 中实现 didReceiveRemoteNotification
方法:
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
print("Received remote notification: \(userInfo)")
completionHandler(.newData)
}
确保在 AppDelegate 中实现 userNotificationCenter(_:didReceive:withCompletionHandler:)
方法:
func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
print("User tapped on notification: \(response.notification.request.content.userInfo)")
completionHandler()
}
通过以上步骤,可以确保在 iOS 10 及以上版本中正确处理远程通知。
