iphone - How to use an IBOutlet from parent class? -

i'm working on ios , having trouble accessing iboutlet parent class, in case label life of character.

my viewcontroller (parent) this:

@interface opponentviewcontroller : uiviewcontroller { iboutlet uilabel *opponent_life; iboutlet opponentview *opponentview; } @end 

the opponentview (child) class character (image) reside , player touch interaction. when player touch opponentview label should refreshed.

- (void)touchesbegan:(nsset *)touches withevent:(uievent *)event {  }  

thanks.

if i'm understanding question correctly update opponent_life when ever detect touch in opponentview. here 2 ways of assigning label view can used tocuhesbegan:withevent:

1. assigning label view in ib

@interface opponentview : uiview {   iboutlet uilabel *opponent_life; } 

in nib file opponentviewcontroller change type of view uiview opponentview , connect label outlet of view.

2. assigning label in viewdidload

@interface opponentview : uiview {   uilabel *opponent_life; }  @property (nonatomic, retain) uilabel *opponent_life; 

in `opponentviewcontroller'

- (void)viewdidload {   [super viewdidload];   opponentview.opponent_life = opponent_life; }
