如何在 iOS 中不指定 HTTP 或 HTTPS 的情况下打开 URL?

问题描述：

在我的 iOS 应用中，我使用以下代码打开链接:

In my iOS app I am opening links using the code below:

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:[NSString stringWithFormat:@"%@",myurl]]];

链接是动态的，不提供 HTTP/HTTPS.

The links come dynamically and HTTP/HTTPS is not provided.

我无法对 HTTP 或 HTTPS 进行硬编码，因为我不知道该 URL 是否包含 HTTP 或 HTTPS.如何在不指定 HTTP 或 HTTPS 的情况下打开 URL?

I cannot hardcode HTTP or HTTPS because I don't know if the URL has HTTP or HTTPS. How can I open a URL without specifying HTTP or HTTPS?

Swift 的单线解决方案:

One-liner solution for Swift:

let urlString = "example.com"
let validUrlString = dataText.hasPrefix("http") ? urlString : "http://\(urlString)"
