Could we call UIFont using Objective-C Runtime
Something like:
id class_UIFont = objc_getClass("UIFont");
SEL sel_labelFontSize = sel_registerName("labelFontSize");
float size = objc_msgSend_fpret(class_UIFont, sel_labelFontSize);
?
Anyway, we are back to the original question: What font to use.
Reading Richard's original request we are still not getting the recommend font
which is bold.
I start to think the answer to get this right in the CSS…
