I know it doesn't support NSAttributedString. However,
CFAttributedStringRef is supported. (That's why I'm using it.) The
documentation reads:
"iPhone OS Note: While Core Foundation on iPhone OS contains
CFAttributedString, there are no additions to the APIs in UIKit to
add specific attributes such as font, style, or color, and there
are no APIs to draw attributed strings."
My question is about casting CFAttributedStringRef to id, which
appears not to work in certain circumstances. For example, adding
an (id)CFAttributedStringRef to an NSMutableArray appears to work
fine... CFGetRetainCount() reports an increase and decrease in the
retain count after adding/removing.
Wrap CFAttributedStringRef (or CFMutableAttributedStringRef) in a
class of your own making. Then you can be sure it will autorelease
correctly.
All it would need is a ref method/property that returns
CFAttributedStringRef (or CFMutableAttributedStringRef), and a
dealloc to call the appropriate CF function on the ref. This seems
almost trivial to write, and would probably take less time than it
took to create the example showing the failure.
