如何为用户提供丰富的通知服务（包括图片图标）？

Question

最近我在做一个项目，它需要嵌入丰富的通知。所以我从火力基地接受服务。最初我从这些网站尝试过。并且在 youtube 中有一些爱好项目，他们从本地机器发送通知。

UNNotificationAttachment with UIImage or Remote URL

How to implement rich notifications in ios 10 with Firebase

How to send Image with firebase Push Notification using swift 3

但我花了将近 16 个小时。它给了我 0 输出，因为标题，副标题很好地来自 firebase，但没有图像图标的迹象。

请给我建议任何方法或好的视频或其他东西。

您的应用目标的 plist 应包含以下行

<key>NSExtensionPointIdentifier</key> 
<string>com.apple.usernotifications.service</string> 
<key>NSExtensionPrincipalClass</key> 
<string>$(PRODUCT_MODULE_NAME).NotificationService</string>

您的扩展程序的 plist 应该如下所示

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
