ios - Crash with "message sent to deallocated instance" when touching UITextField -

i have implementation of uiviewcontroller following code viewdidload:

- (void)viewdidload {     [super viewdidload];      // additional setup after loading view nib.     (int i=0; i<10; i++)     {         nsuserdefaults *prefs = [nsuserdefaults standarduserdefaults];          nsstring *speeddial = [prefs stringforkey:[nsstring stringwithformat:@"%s%i", "fav",i]];         if ([speeddial length] > 0)             [self gettextfield:i].text = speeddial;          [self gettextfield:i].returnkeytype = uireturnkeydone;         [self gettextfield:i].delegate = self;     }  } 

when touch uitextfield on screen app crashes , output: "message sent deallocated instance". have same error when pressing button on view guess error @ uiviewcontroller level. using arc , uitextfield defined strong. have tried looking memory management issues no success.

any idea?

thanks, simon

in [self.view addsubview:favorites.view]; using favorites view allowing controller fall out of scope. object creates favorites should keep around strong reference instead of making local variable.
