Question

我需要“挂钩”Notification对象。我想要每一个

new Notification(title);

登录到控制台标题，但也创建通知。我想保留Notification对象的值（例如，如果在Notification请求权限之前，则保留此权限）

怎么做？

您可以覆盖默认构造函数：

static func post(image: UIImage, for username: String) {

    let imageData = UIImagePNGRepresentation(image)
    let base64Image = imageData?.base64EncodedString(options: .lineLength64Characters)

    let url = "https://api.imgur.com/3/upload"

    let parameters = [
        "image": base64Image
    ]

    Alamofire.upload(multipartFormData: { multipartFormData in
        if let imageData = UIImageJPEGRepresentation(image, 1) {
            multipartFormData.append(imageData, withName: username, fileName: "\(username).png", mimeType: "image/png")
        }

        for (key, value) in parameters {
            multipartFormData.append((value?.data(using: .utf8))!, withName: key)
        }}, to: url, method: .post, headers: ["Authorization": "Client-ID " + Constants.IMGUR_CLIENT_ID],
            encodingCompletion: { encodingResult in
                switch encodingResult {
                case .success(let upload, _, _):
                    upload.response { response in
                        //This is what you have been missing
                         let json = try? JSONSerialization.jsonObject(with: response.data!, options: .allowFragments) as! [String:Any]
                         print(json)
                         let imageDic = json?["data"] as? [String:Any]
                         print(imageDic?["link"])
                    }
                case .failure(let encodingError):
                    print("error:\(encodingError)")
                }
    })

}
