Connecting actions (methods) to tab bar item


hello!

i've googled , googled, , dont seem find complete answer question.

can't find solution how can add actions tab bar items.

have delegate class:
code:
  @interface myprojectappdelegate : nsobject <uiapplicationdelegate, uitabbarcontrollerdelegate> {      uiwindow *window;      uitabbarcontroller *rootcontroller;    }
and implementation

code:
  #import "myprojectappdelegate.h"    @implementation myprojectappdelegate    @synthesize window;  @synthesize rootcontroller;    #pragma mark -  #pragma mark application lifecycle    -(void) applicationdidfinishlaunching:(uiapplication *)application{  	[window addsubview:rootcontroller.view];  	[window makekeyandvisible];  }  
and i've created seperate classes(with xib files) each tab bar item. switching between views works beautifully. problem however, when select view, want content in view refreshed.



i've seen documentation, , tried understand didselectitem method, cant figure out how working. can please push me in right direction? dont understand how methods in delegate class can acess content in view?
 

2 ways can "try" achieve u wan't, because don't know u mean, "refreshed".

have code in viewdidload.
want put in viewwillappear. first try.
in delegate methods of uitabbarcontroller (if u command clicked it..) u see there methods u maybe use?
code:
@optional  - (bool)tabbarcontroller:(uitabbarcontroller *)tabbarcontroller shouldselectviewcontroller:(uiviewcontroller *)viewcontroller  - (void)tabbarcontroller:(uitabbarcontroller *)tabbarcontroller didselectviewcontroller:(uiviewcontroller *)viewcontroller;    - (void)tabbarcontroller:(uitabbarcontroller *)tabbarcontroller willbegincustomizingviewcontrollers:(nsarray *)viewcontrollers  - (void)tabbarcontroller:(uitabbarcontroller *)tabbarcontroller willendcustomizingviewcontrollers:(nsarray *)viewcontrollers changed:  - (void)tabbarcontroller:(uitabbarcontroller *)tabbarcontroller didendcustomizingviewcontrollers:(nsarray *)viewcontrollers changed:(bool)changed;  @end
there choices.
1 called, didselectviewcontroller.
u maybe add code there..
