objective c - How to check for attribute on NSMutableAttributedString -


i execute block of code on nsmutableattributedstring iff attribute nsstrikethroughstyleattributename set. there easy way check existence of attribute?

what this:

nsmutableattributedstring *yourstring; //initialize these things before calling method below nsrange range; if ([yourstring attribute:nsstrikethroughstyleattributename atindex:text.length - 1 effectiverange:&range]) {     //dosomestuff }

the documentation says returns "the value attribute named attributename of character @ index, or nil if there no such attribute.". have check if method returns that's not nil.
