URL-encoding and HTML-encoding NSStrings

Question

Is their a method to encode/decode HTML and URL (in Xcode, using Objective-C)?

[NSString stringWithContentsOfFile:<#(NSString *)path#> encoding:<#(         


        

Answer 1

To do HTML/XML entity encoding, you can use a CFMutableString function:

NSString *result = .....;
CFStringTransform((CFMutableStringRef)result, NULL, kCFStringTransformToXMLHex, false);

By setting the last parameter of CFStringTransform to true, it should work for decoding (hex) entities as well.
