Yes. Just connect the switch to the controller in the nib to form an action; the correct event will be selected automatically. Please understand that I am trying to educate, not criticize, when I say that for success in programming (for iOS or anything else) you must be willing to try stuff - on your own. This has nothing to do with being a newbie - it's a matter of character and determination. You could have selected the UIButton within the UIBarButtonItem; you just didn't try hard enough. If you had, repeated clicking and playing around would have led you to the truth. Similarly, to discover what event is appropriate for a UISwitch, try different events and see. m. -- matt neuburg, phd = m...@tidbits.com, http://www.tidbits.com/matt/ pantes anthropoi tou eidenai oregontai phusei Among the 2007 MacTech Top 25, http://tinyurl.com/2rh4pf AppleScript: the Definitive Guide, 2nd edition http://www.tidbits.com/matt/default.html#applescriptthings Take Control of Exploring & Customizing Snow Leopard http://tinyurl.com/kufyy8 RubyFrontier! http://www.apeth.com/RubyFrontierDocs/default.html TidBITS, Mac news and reviews since 1990, http://www.tidbits.com _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
