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

Use CFStringTransform for HTML entity encoding/decoding:

CFStringTransform((CFTypeRef)yourMutableString, NULL, CFSTR("Any-Hex/XML"), FALSE );

You need to use the ICU transform "Any-Hex/XML". kCFStringTransformToXMLHex isn't aggressive enough.
