我在通知服务扩展方面遇到了问题。 我已经按照逐步文档进行了操作 https://developer.xamarin.com/guides/ios/platform_features/introduction-to-ios10/user-notifications/enhanced-user-notifications/#Working_with_Service_Extensions
实施时，我已按以下方式进行操作。
- 添加与我的应用程序相同前缀的通知服务扩展（添加后缀，例如：APP：com.testapp.main - EXT：com.testapp.main.notificationextension）
- 在苹果会员中心创建APPID标识符com.testapp.main.notificationextension
- 创建证书和配置文件以发送推送通知给APP ID com.testapp.main.notificationextension
- 将Xcode和Xamarin证书和配置文件导入
- 使用通知扩展引用构建我的应用程序。
- 创建存档以上传到TestFlight
- 使用其分发证书和配置文件签署应用程序
- 使用其分发证书和配置文件签署扩展名
- 上传到TestFlight
- 下载并允许我的应用程序推送通知
- 使用Localytics Dashboard发送富推送通知进行消息传递 - 设备接收推送通知但未通过NotificationService.cs的通知服务扩展代码进行传递！
这是我的NotificationService代码：
using System;
using Foundation;
using UserNotifications;
namespace NotificationServiceExtension
{
[Register("NotificationService")]
public class NotificationService : UNNotificationServiceExtension
{
Action<UNNotificationContent> ContentHandler { get; set; }
UNMutableNotificationContent BestAttemptContent { get; set; }
const string ATTACHMENT_IMAGE_KEY = "ll_attachment_url";
const string ATTACHMENT_TYPE_KEY = "ll_attachment_type";
const string ATTACHMENT_FILE_NAME = "-localytics-rich-push-attachment.";
protected NotificationService(IntPtr handle) : base(handle)
{
// Note: this .ctor should not contain any initialization logic.
}
public override void DidReceiveNotificationRequest(UNNotificationRequest request, Action<UNNotificationContent> contentHandler)
{
System.Diagnostics.Debug.WriteLine("Notification Service DidReceiveNotificationRequest");
ContentHandler = contentHandler;
BestAttemptContent = (UNMutableNotificationContent)request.Content.MutableCopy();
if (BestAttemptContent != null)
{
string imageURL = null;
string imageType = null;
if (BestAttemptContent.UserInfo.ContainsKey(new NSString(ATTACHMENT_IMAGE_KEY)))
{
imageURL = BestAttemptContent.UserInfo.ValueForKey(new NSString(ATTACHMENT_IMAGE_KEY)).ToString();
}
if (BestAttemptContent.UserInfo.ContainsKey(new NSString(ATTACHMENT_TYPE_KEY)))
{
imageType = BestAttemptContent.UserInfo.ValueForKey(new NSString(ATTACHMENT_TYPE_KEY)).ToString();
}
if (imageURL == null || imageType == null)
{
ContentHandler(BestAttemptContent);
return;
}
var url = NSUrl.FromString(imageURL);
var task = NSUrlSession.SharedSession.CreateDownloadTask(url, (tempFile, response, error) =>
{
if (error != null)
{
ContentHandler(BestAttemptContent);
return;
}
if (tempFile == null)
{
ContentHandler(BestAttemptContent);
return;
}
var cache = NSSearchPath.GetDirectories(NSSearchPathDirectory.CachesDirectory, NSSearchPathDomain.User, true);
var cachesFolder = cache[0];
var guid = NSProcessInfo.ProcessInfo.GloballyUniqueString;
var fileName = guid + ATTACHMENT_FILE_NAME + imageType;
var cacheFile = cachesFolder + fileName;
var attachmentURL = NSUrl.CreateFileUrl(cacheFile, false, null);
NSError err = null;
NSFileManager.DefaultManager.Move(tempFile, attachmentURL, out err);
if (err != null)
{
ContentHandler(BestAttemptContent);
return;
}
UNNotificationAttachmentOptions options = null;
var attachment = UNNotificationAttachment.FromIdentifier("localytics-rich-push-attachment", attachmentURL, options, out err);
if (attachment != null)
{
BestAttemptContent.Attachments = new UNNotificationAttachment[] { attachment };
}
ContentHandler(BestAttemptContent);
return;
});
task.Resume();
}
else {
ContentHandler(BestAttemptContent);
}
}
public override void TimeWillExpire()
{
// Called just before the extension will be terminated by the system.
// Use this as an opportunity to deliver your "best attempt" at modified content, otherwise the original push payload will be used.
ContentHandler(BestAttemptContent);
return;
}
}
}
DidReceiveNotificationRequest没有被执行吗？ - Demitrian
