Encode NSString for XML/HTML

Question

Is there a way to HTML encode a string (NSString) in Objective-C, something along the lines of Server.HtmlEncode in .NET?

Answer 1

For URL encoding:

NSString * encodedString = [originalString
      stringByAddingPercentEscapesUsingEncoding:NSASCIIStringEncoding];

See Apple's NSString documentation for more info.

For HTML encoding:

Check out CFXMLCreateStringByEscapingEntities, which is part of the Core Foundation XML library, but should still do the trick.
