ios - '.' 之后的 Swift/iOS/预期成员名称

Question

我正在尝试使用以下教程(在 Swift 中!)为应用程序创建后端:

https://backendless.com/feature-2-registering-app-users-with-the-user-registration-api/#

但在 registerUser() 函数中，它告诉我:预期的成员名称在“.”之后 在 Types.try({ () ->无效

其他一切正常。即使我删除此函数并执行 registerUserAsync()，也会创建用户。所以这不是框架导入问题。

这可能是 Swift1/2 问题吗？由于代码在 Swift1 (println(...))

感谢任何帮助

代码:

//  ViewController.swift
//  F2RegisteredUsersSwift

import UIKit

class ViewController: UIViewController {

    let APP_ID = "YOUR-APP-ID"
    let SECRET_KEY = "YOUR-SECRET-KEY"
    let VERSION_NUM = "v1"

    var backendless = Backendless.sharedInstance()

    override func viewDidLoad() {
        super.viewDidLoad()

        backendless.initApp(APP_ID, secret:SECRET_KEY, version:VERSION_NUM)

        registerUser()
        registerUserAsync()
    }

    func registerUser() {

        Types.try({ () -> Void in

            var user = BackendlessUser()
            user.email = "spiday@backendless.com"
            user.password = "greeng0blin"
            user.setProperty("phoneNumber", object:"214-555-1212")

            var registeredUser = self.backendless.userService.registering(user)
            println("User has been registered (SYNC): \(registeredUser)")
            },

            catch: { (exception) -> Void in
                println("Server reported an error: \(exception as Fault)")
            })
    }

    func registerUserAsync() {

        var user = BackendlessUser()
        user.email = "green.goblin@backendless.com"
        user.password = "sp1day"
        user.setProperty("phoneNumber", object:"214-555-1212")

        backendless.userService.registering(user,
            response: { (var registeredUser : BackendlessUser!) -> () in
                println("User has been registered (ASYNC): \(registeredUser)")
            },
            error: { (var fault : Fault!) -> () in
                println("Server reported an error: \(fault)")
            }
        )
    }

}

“try”是 Swift 2 中的保留字(用于错误处理)。如果您的 Swift 1 代码中有一个名为“try”的方法或函数，您最好重命名它。
