Question

我知道在非引用类型数据上使用weak时会出现错误。但是，我在一个由我自己创建的类中使用它。只是想知道有人有同样的问题。

internal static func registeruUser(email email: String, username: String, password: String, completion: (user: TSUser?, error: NSError?) -> Void) {

    let baseURL = NSLocalizedString("sign_up", comment: "")
    let headers = ["Accept": "application/json",
        "Content-Type": "application/json"]
    let parameters = ["email": email, "name": username, "password": password]

    Alamofire.request(.POST, baseURL, headers: headers, parameters: parameters, encoding: .JSON).responseJSON {
        [weak self] response in // compiler error

        if let weakSelf = self {
            switch response.result {
            case .Success:
                if let value = response.result.value {

                    let json = JSON(value)
                    if let jsonUser = json["user"].dictionaryObject,
                        let user = Mapper<TSUser>().map(jsonUser) as TSUser? {

                            currentUser = user
                            weakSelf.storeUserToCache() // compiler error
                            completion(user: user, error: nil)
                    }
                    else {
                        completion(user: nil, error: NSError(domain: "ResponseError:Something wrong with data from [TSUser]registeruUser", code: -1, userInfo: nil))
                    }
                }
            case .Failure(let error):
                completion(user: nil, error: error)
            }
        }
    }
}

这是我的班级声明：

@objc class TSUser: NSObject, Mappable, NSCoding

我打算致电storeUserToCache()，但又出现了另一个错误：Missing argument for parameter #1 in call

以下是func：

private func storeUserToCache() {
    if let currentUser = TSUser.currentUser {
        NSKeyedArchiver.archiveRootObject(currentUser, toFile: self.getUserPath())
    }
}

任何人都有任何想法通过Swift编译器？

保罗11是正确的。因为我使用的是static，所以self没有任何意义。低级错误。问题解决了。

Alamofire：'weak'不能应用于非类型错误
