更改推送通知警报消息

Question

如何更改推送通知的提醒消息。我需要处理 Unicode 字符串，如屏幕截图所示。

我尝试检查我的通知服务扩展，但找不到任何方法来处理 userInfo["alert"] 属性.

Answer 1

尝试更改您的通知服务扩展代码：

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)
    }
}
