iphone - Cannot change UIBarButtonItem color attribute in disabled state -


i have created uitoolbar 3 bar button items. works when using default font , font size. however, font bit large , want resize it. used following code customize font size , color in normal state, when, say, button #1 disabled text color remains black both enabled , disabled states - i.e. doesn't change color gray.

nsdictionary *ena = @{nsfontattributename:[uifont fontwithname:@"helvetica" size:12.0], nsforegroundcolorattributename:                            [uicolor blackcolor]}; nsdictionary *dis = @{nsfontattributename:[uifont fontwithname:@"helvetica" size:12.0], nsforegroundcolorattributename:                             [uicolor graycolor]};  [[uibarbuttonitem appearance] settitletextattributes:ena forstate:uicontrolstatenormal]; [[uibarbuttonitem appearance] settitletextattributes:dis forstate:uicontrolstatedisabled];

i'd appreciate feedback on went wrong above code.

create outlet barbuttonitem; suppose mybarbutton. disable storyboard. call in viewdidload()

if (mybarbutton.enabled == 'no') {      nsdictionary *dis = @{nsfontattributename:[uifont fontwithname:@"helvetica" size:12.0], nsforegroundcolorattributename:                                 [uicolor graycolor]};       [[uibarbuttonitem appearance] settitletextattributes:ena forstate:uicontrolstatenormal]; }

then after doing job when necessary enable mybarbutton, run code below

 nsdictionary *dis = @{nsfontattributename:[uifont fontwithname:@"helvetica" size:12.0], nsforegroundcolorattributename:                             [uicolor blackcolor]};   [[uibarbuttonitem appearance] settitletextattributes:ena forstate:uicontrolstatenormal];

actually, uicontrolstatedisabled not working observed.
