Answer 1

To quote coding guidlines for Cocoa: Code Naming Basics:

• In general, don’t abbreviate names of things. Spell them out, even if they’re long.
• For names composed of multiple words, do not use punctuation marks as parts of names or as separators (underscores, dashes, and so on); instead, capitalize the first letter of each word and run the words together (for example, runTheWordsTogether)—this is known as camel-casing.
• It is good to be both clear and brief as possible, but clarity shouldn’t suffer because of brevity.
• Names shouldn’t be self-referential.

So yeah, either what nonamelive proposed, or try to get rid of “button” prefix/suffix as well if possible.
