Text encoding problem between NSImage, NSData, and NSXMLDocument
- by andyvn22
I'm attempting to take an NSImage and convert it to a string which I can write in an XML document.
My current attempt looks something like this:
[xmlDocument setCharacterEncoding: @"US-ASCII"];
NSData* data = [image TIFFRepresentation];
NSString* string = [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding];
//Put string inside of NSXMLElement, write out NSXMLDocument.
Reading back in looks something like this:
NSXMLDocument* newXMLDocument = [[NSXMLDocument alloc] initWithData:data options:0 error:outError];
//Here's where it fails. I get:
//Error Domain=NSXMLParserErrorDomain Code=9 UserInfo=0x100195310 "Line 7: Char 0x0 out of allowed range"
I assume I'm missing something basic. What's up with this encoding issue?
