Swift 3和JSON –通过在后台运行URL更新数据库 [英] Swift 3 and JSON – Updating the database by running a URL in the background

问题描述

我可以访问某个链接(假设它是 www.google. com )，这样当我在浏览器中打开它时，它将更新数据库中JSON代码的特定部分.根据构成链接一部分的数字，它会调整数据中的某个值.

There is a certain link I have access to (let's pretend it's www.google.com), such that when I open it up in my browser, it updates a certain section of the JSON code in my database. Based on the numbers that make up a portion of the link, it adjusts a certain value in the data.

我需要能够在应用程序中打开"此链接，而无需实际打开UIWebview并直观地访问该网站.我只需要数据库内部的JSON数据自行更新(用户不知道它甚至发生过).

I need to be able to "open" this link within the app, without actually opening up a UIWebview and visually visiting the site. I just need this JSON data inside the database to update on its own (with the user unaware that it even happened).

我在这里遇到的问题是我根本不知道该怎么做. 如何在不打开Safari浏览器的情况下访问此链接?

The problem I'm having here is that I simply don't know how this is done. How do I cause this link to be visited without opening up a Safari browser?

推荐答案

您也可以使用UIWebView而不显示它，就像这样(快速3):

You could also use the UIWebView without ever showing it, like this (Swift 3):

    func webView() {

    let theWebView: UIWebView

    theWebView = UIWebView(frame: UIScreen.main.bounds)

    theWebView.delegate = self

    if let theURL = URL(string: "your URL") {
        let request = URLRequest(url: theURL)
        theWebView.loadRequest(request)
    }
}

只是不要将其添加到视图中.

Just don't add it to the view.
