我一直在使用Xamarin中使用Firebase集成推送通知。我创建了开发人员配置配置文件，还生成了p12文件并附加了Firebase Console项目。
我正在从云消息传递(来自FCM控制台项目(中发送通知，该通知在关闭应用程序时会收到，如果我启动了应用程序，请发送通知，该通知未接收。
这是火基初始化
LoadApplication(new App());
if (UIDevice.CurrentDevice.CheckSystemVersion(10, 0))
{
UNUserNotificationCenter.Current.RequestAuthorization(UNAuthorizationOptions.Alert | UNAuthorizationOptions.Badge | UNAuthorizationOptions.Sound,
(granted, error) =>
{
if (granted)
InvokeOnMainThread(UIApplication.SharedApplication.RegisterForRemoteNotifications);
});
}
else if (UIDevice.CurrentDevice.CheckSystemVersion(8, 0))
{
var pushSettings = UIUserNotificationSettings.GetSettingsForTypes(
UIUserNotificationType.Alert | UIUserNotificationType.Badge | UIUserNotificationType.Sound,
new NSSet());
UIApplication.SharedApplication.RegisterUserNotificationSettings(pushSettings);
UIApplication.SharedApplication.RegisterForRemoteNotifications();
}
else
{
UIRemoteNotificationType notificationTypes = UIRemoteNotificationType.Alert | UIRemoteNotificationType.Badge | UIRemoteNotificationType.Sound;
UIApplication.SharedApplication.RegisterForRemoteNotificationTypes(notificationTypes);
}
//FirebasePushNotificationManager.Initialize(launchOptions,true);
return base.FinishedLaunching(uiApplication, launchOptions);
在我的情况下，拳头条件是正确的(如果(uidevice.currentdevice.checksystemversion(10，0(((和通知注册成功
和每次调试应用程序
时都会调用注册的forremoteNotificativation方法当我从云消息发送通知时， didReceivereMoteNotification callled，但通知如果应用程序闭合(背景(通知到
public override void RegisteredForRemoteNotifications(UIApplication application, NSData deviceToken)
{
FirebasePushNotificationManager.DidRegisterRemoteNotifications(deviceToken, FirebaseTokenType.Sandbox);
}
public override void FailedToRegisterForRemoteNotifications(UIApplication application, NSError error)
{
FirebasePushNotificationManager.RemoteNotificationRegistrationFailed(error);
}
// To receive notifications in foregroung on iOS 9 and below.
// To receive notifications in background in any iOS version
public override void DidReceiveRemoteNotification(UIApplication application, NSDictionary userInfo, Action<UIBackgroundFetchResult> completionHandler)
{
// If you are receiving a notification message while your app is in the background,
// this callback will not be fired 'till the user taps on the notification launching the application.
// If you disable method swizzling, you'll need to call this method.
// This lets FCM track message delivery and analytics, which is performed
// automatically with method swizzling enabled.
FirebasePushNotificationManager.DidReceiveMessage(userInfo);
// Do your magic to handle the notification data
System.Console.WriteLine(userInfo);
completionHandler(UIBackgroundFetchResult.NewData);
}
public override void ReceivedRemoteNotification(UIApplication application, NSDictionary userInfo)
{
base.ReceivedRemoteNotification(application, userInfo);
}
// To receive notifications in foreground on iOS 10 devices.
[Export("userNotificationCenter:willPresentNotification:withCompletionHandler:")]
public void WillPresentNotification(UNUserNotificationCenter center, UNNotification notification, Action<UNNotificationPresentationOptions> completionHandler)
{
// Do your magic to handle the notification data
System.Console.WriteLine(notification.Request.Content.UserInfo);
}
public void ApplicationReceivedRemoteMessage(RemoteMessage remoteMessage)
{
Console.WriteLine(remoteMessage.AppData);
}
任何人都可以提出一些有用的建议吗？
预先感谢！
对于运行iOS 9及以下的设备，覆盖AppDelegate的DidreceivereMoteNotification方法处理客户端应用程序在前景时收到的通知，以及发送给客户端的所有数据消息。消息是键和值的字典：
public override void DidReceiveRemoteNotification (UIApplication application, NSDictionary userInfo, Action<UIBackgroundFetchResult> completionHandler)
{
// Do your magic to handle the notification data
System.Console.WriteLine (userInfo);
}
对于iOS 10设备及更高版本，实现iunusernotificationcenterdelegate界面和覆盖willPresentnotification方法，以处理客户端应用在前景中收到的通知：
// To receive notifications in foreground on iOS 10 devices.
[Export("userNotificationCenter:willPresentNotification:withCompletionHandler:")]
public void WillPresentNotification(UNUserNotificationCenter center, UNNotification notification, Action<UNNotificationPresentationOptions> completionHandler)
{
// Do your magic to handle the notification data
System.Console.WriteLine(notification.Request.Content.UserInfo);
}
public void ApplicationReceivedRemoteMessage(RemoteMessage remoteMessage)
{
Console.WriteLine(remoteMessage.AppData);
}
我解决了Foreground中未收到通知的问题。我实现了NotificationDelegate类，然后通过UNUserNotificationCenterDelegate继承了此类之后，创建用于在前景iOS 10
public class NotificationDelegate : UNUserNotificationCenterDelegate
{
public NotificationDelegate()
{
}
public override void WillPresentNotification(UNUserNotificationCenter center, UNNotification notification, Action<UNNotificationPresentationOptions> completionHandler)
{
// Do something with the notification
Console.WriteLine("Active Notification: {0}", notification);
// Tell system to display the notification anyway or use
// `None` to say we have handled the display locally.
completionHandler(UNNotificationPresentationOptions.Alert|UNNotificationPresentationOptions.Sound);
}
public override void DidReceiveNotificationResponse(UNUserNotificationCenter center, UNNotificationResponse response, Action completionHandler)
{
// Take action based on Action ID
switch (response.ActionIdentifier)
{
case "reply":
// Do something
break;
default:
// Take action based on identifier
if (response.IsDefaultAction)
{
// Handle default action...
}
else if (response.IsDismissAction)
{
// Handle dismiss action
}
break;
}
completionHandler();
}
}
I am facing this issue(not receive notification in foreground) because in WillPresentNotification method i am sending only UNNotificationPresentationOptions.Alert (completionHandler(UNNotificationPresentationOptions.Alert);) but both alert and sound are required for notification in Foreground and Background in iOS 10
然后在服务器中执行登录名的代码
public override bool FinishedLaunching(UIApplication uiApplication, NSDictionary launchOptions)
{
global::Xamarin.Forms.Forms.Init();
if (UIDevice.CurrentDevice.CheckSystemVersion(10, 0))
{
UNUserNotificationCenter center = UNUserNotificationCenter.Current;
center.RequestAuthorization(UNAuthorizationOptions.Alert | UNAuthorizationOptions.Sound | UNAuthorizationOptions.Badge, (bool arg1, NSError arg2) =>
{
if (arg1)
InvokeOnMainThread(UIApplication.SharedApplication.RegisterForRemoteNotifications);
});
center.Delegate = new NotificationDelegate();
}
else if (UIDevice.CurrentDevice.CheckSystemVersion(8, 0))
{
var settings = UIUserNotificationSettings.GetSettingsForTypes(UIUserNotificationType.Alert | UIUserNotificationType.Badge | UIUserNotificationType.Sound, new NSSet());
UIApplication.SharedApplication.RegisterUserNotificationSettings(settings);
}
return base.FinishedLaunching(uiApplication, launchOptions);
}
然后在AppDelegate类中创建注册方法
public override void RegisteredForRemoteNotifications(UIApplication application, NSData deviceToken)
{
FirebasePushNotificationManager.DidRegisterRemoteNotifications(deviceToken, FirebaseTokenType.Sandbox);
}
如果您在这种情况下使用Debug Mode，那么重要的想法
FirebasePushNotificationManager.DidRegisterRemoteNotifications(deviceToken, FirebaseTokenType.Sandbox);
和在AntiTlement.plist中添加此
<plist version="1.0">
<dict>
<key>aps-environment</key>
<string>development</string>
</dict>
</plist>
如果您在这种情况下使用Release Mode
FirebasePushNotificationManager.DidRegisterRemoteNotifications(deviceToken, FirebaseTokenType.Production);
和在AntiTlement.plist中添加此
<plist version="1.0">
<dict>
<key>aps-environment</key>
<string>production</string>
</dict>
</plist>
