Cocoa – NSURL URLWithString: is null with non-english accented characters

cocoansurlspecial characters

I have the following string…

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

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

[NSURL URLWithString:googleSearchString];

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

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

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

NSUrl URLWithString: will not escape the string as stated by the docs:

This method expects URLString to contain any necessary percent escape codes, which are ‘:’, ‘/’, ‘%’, ‘#’, ‘;’, and ‘@’. Note that ‘%’ escapes are translated via UTF-8

However, you should be able to do the following using stringByAddingPercentEscapesUsingEncoding::

NSString *myString = @"http://foo.bar/?key[]=value[]<>";
NSURL *myUrl = [NSURL URLWithString:[myString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];
