How check font lineHeight ( font.lineHeight) is depricated or not using API (with out checking OS versions)

Question

Hi friends ..

i want to check lineHeight property of font is is deprecated or not using respondsToSelector . As respondsToSelector takes only method name .. how can i assign property to it ??

See the section labeled "Accessor Method Names" in Apple's Objective-C Programming Language document for more details on getter and setter names for declared properties.
