更改推送通知警报消息

Question

如何修改我的推送通知的警报消息。我需要按照屏幕截图所示处理Unicode字符串。

我想检查我的通知服务扩展，但我找不到任何办法来处理用户信息[“警报”]属性。

试着改变你通知服务扩展代码：

override func didReceive(_ request: UNNotificationRequest, withContentHandler contentHandler: @escaping (UNNotificationContent) -> Void) { 
    self.contentHandler = contentHandler 
    bestAttemptContent = (request.content.mutableCopy() as? UNMutableNotificationContent) 

    if let bestAttemptContent = bestAttemptContent { 
     // Modify the notification content here 
     // Convert received string 
     let data = bestAttemptContent.body.data(using: .utf8)! 
     // Apply encoded string 
     bestAttemptContent.body = String(data: data, encoding: .utf16) 

     contentHandler(bestAttemptContent) 
    } 
}
