I have an attributed string. I want to preserve the attributes within
the string but set all the actual characters to uppercase, lowercase,
etc.
According to the docs for NSMutableAttributedString, the -
mutableString method returns a mutable string that the receiver tracks
changes to in order to preserve attribute runs. However, when I call -
setString: or -replaceCharactersInRange:withString: on this, all my
attributes are removed.
How can I do this without my attributes going AWOL?
NSMutableAttributedString* ttd = [[[self textSubstitutor]
substitutedStringWithObject:object] mutableCopy];
// capitalize all the text according to the capitalization setting:
NSMutableString* mStr = [ttd mutableString];
// Docs: "Discussion
// The receiver tracks changes to this string and keeps its attribute
mappings up to date."
NSRange range = NSMakeRange( 0, [mStr length]);
switch([self capitalization])
{
default:
break;
case kDKTextCapitalizationUppercase:
[mStr replaceCharactersInRange:range withString:[mStr
uppercaseString]]; // setString: doesn't work either
break;
case kDKTextCapitalizationLowercase:
[mStr replaceCharactersInRange:range withString:[mStr
lowercaseString]];
break;
case kDKTextCapitalizationCapitalize:
[mStr replaceCharactersInRange:range withString:[mStr
capitalizedString]];
break;
}
