NSURL URLWithString：对于非英语重音字符为空 [英] NSURL URLWithString: is null with non-english accented characters

问题描述

我有以下字符串...

I have the following string...

NSString *googleSearchString = @"http://www.google.com/search?q=lyrics+%22Tænder+På+Dig%22+%22Jakob+Sveistrup%22";

请注意，它有一些重音字符。当我试图把它变成一个url返回的url是null ...

Notice that it has some accented characters. When I try to turn that into a url the returned url is null...

[NSURL URLWithString:googleSearchString];

因此，通常url工作除非字符串中有非重音符号。

So normally the url works except when there are accented non-english characters in the string. Any help on how to handle that?

推荐答案

您需要转义特殊字符才能使其正常工作。类似：

You need to escape the special characters to make it work properly. Something like:

[NSURL URLWithString:[googlSearchString stringByAddingPercentEscapesUsingEncoding: NSUTF8StringEncoding]];
