ios - 推送通知不显示自定义通知

Question

嘿，我正在尝试从 firebase 获取推送通知并根据需要自定义它们，但即使我在应用程序启动选项中设置了通知类别，它也总是给我默认的推送通知。所以请告诉我在这种情况下如何显示自定义推送通知()。这是我的应用程序委托(delegate)文件:-

我的扩展文件包含这个:-

类 NotificationViewController:UIViewController，UNNotificationContentExtension {

@IBOutlet var label: UILabel?

var contentHandler: ((UNNotificationContent) -> Void)?
var bestAttemptContent: UNMutableNotificationContent?

override func viewDidLoad() {
    super.viewDidLoad()
    // Do any required interface initialization here.
}

func didReceive(_ notification: UNNotification) {
    self.label?.text = notification.request.content.body
}

我通过 fcm 发送的 JSON 是:-

 {
  "to": "c0jlO4sWiog:APA91bGSlGYe27xA5DdyLcgm1xlSyxmWrfPOzNHnTv6Jp0QT0MnzqHoekSpnuNvppGDwQYB-jyV-gtxvYDdBjxsc_I1u1uvYqNHqXEB8ki-UnRNKqFJcwCSAljNOm2Ax0AuFFLy5qMq1",
  "priority" : "high",
   "notification" : {
  "title": "adfsas",
  "body" : "dasdfadf",
  "category" : "myNotificationCategory",
  "content_available": true,
  "mutable_content": 1
   },
   "data": {
    "text": "fadsfa",
    "title":"asfdafa",
    "image":"http://feelgrafix.com/data/images/images-1.jpg"
   }
}

Answer 1

对于 fcm 中的类别，您需要提供 click_action: 键来代替类别。

{
  "to": "cVA176y69bk:APA91bFprDK2CeYG8W4P6Fu0bn7FrvlXqI-voZUrNv3MH-HLLl-toswFc1luwjASf5b1phk5fMuy1APd3QcIT9qzsPbiX_dTaxhoGx6y-h05aDxDdcmYiYEWu7e0vuvWeCc9uloZCp1e",
  "priority" : "high",
  "content_available": true,
  "mutable_content": true,

  "notification" : {
  "title": "dsaasf",
  "body" : "afaadfad",
  "click_action" : "myNotificationCategory"
   },
   "data": {
    "text": "adsfaf",
    "title":"asfads",
    "image":"http://feelgrafix.com/data/images/images-1.jpg"
   }
}
