如何在UIWebView中打开西里尔文字域？ [英] How to open cyrillic domain in UIWebView?

问题描述

我尝试在UIWebView中打开cyrillic url，但它可以打开。
我使用以下代码％

I try to open cyrillic url in UIWebView, but it's can open. I use the following code%

urlString = [NSString stringWithFormat:@"http://%@", urlString];
urlString = [urlString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
url = [NSURL URLWithString:urlString];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[_webView loadRequest:request];

如果我尝试打开 https://www.google.ru/webhp?q =президент＃newwindow = 1& q =президент一切正常，但当我尝试打开президент.рф时，它是不起作用。
我需要为开放的西里尔文域做些什么？

If i try to open https://www.google.ru/webhp?q=президент#newwindow=1&q=президент everything is OK, but when I try to open президент.рф it's doesn't work. What I need to do for open cyrillic domain?

推荐答案

要连接到IDN（国际域名）网址，你需要在Punycode中对它们进行编码。例如，此网址将编码为 http：//xn--d1abbgf6aiiy.xn--p1ai 。

To connect to IDN (international domain name) URLs, you need to encode them in Punycode. For example, this URL would be encoded as http://xn--d1abbgf6aiiy.xn--p1ai.

不幸的是，我不知道iOS中有任何内置的punycode支持。但是有第三方工具，如 NSURL-IDN （摘自 OmniNetworking 库。）

Unfortunately I don't know of any built-in punycode support in iOS. But there are third-party tools like NSURL-IDN (which is extracted from the OmniNetworking library).
