iphone - pass uigesturerecognzer data to parent controller -

there master view controller method

- (void)revealgesture:(uipangesturerecognizer *)recognizer{  } 

which works when send mesage froma child viewcontroller using swipe:

uipangesturerecognizer *navigationbarpangesturerecognizer = [[uipangesturerecognizer alloc] initwithtarget:self.navigationcontroller.parentviewcontroller action:@selector(revealgesture:)]; [self.navigationcontroller.navigationbar addgesturerecognizer:navigationbarpangesturerecognizer]; 

i want pass message on within child viewcontroller can house keeping first

    uipangesturerecognizer *navigationbarpangesturerecognizer = [[uipangesturerecognizer alloc] initwithtarget:self action:@selector(revealgesture:)];     [self.navigationcontroller.navigationbar addgesturerecognizer:navigationbarpangesturerecognizer]; 

and

- (void)revealgesture:(uipangesturerecognizer *)recognizer {     [displaysearch resignfirstresponder];     revealcontroller *revealcontroller = [self.navigationcontroller.parentviewcontroller iskindofclass:[revealcontroller class]] ? (revealcontroller *)self.navigationcontroller.parentviewcontroller : nil;      nsdictionary *data = [nsdictionary dictionarywithobjectsandkeys: recognizer, @"recognizer", nil];      [revealcontroller performselector:@selector(revealgesture:) withobject:data]; } 

yes, i'm trying dismiss keyboard before carrying on bit of code works fine if target 'self.navigationcontroller.parentviewcontroller' directly

how add (uipangesturerecognizer *)recognizer nsdictionary?

my code crashes with

-[__nscfdictionary state]: unrecognized selector sent instance 0x8619860 2013-05-02 21:12:05.752 pwc uk[57884:c07] *** terminating app due uncaught exception 'nsinvalidargumentexception', reason: '-[__nscfdictionary state]: unrecognized selector sent instance 0x8619860' 

edit proposed solution worked keyboard didn't respond, needed chage line to

[self searchbarcancelbuttonclicked:searchbar]; 

where searchbar instance of uisearchbar

it looks revealgesture expecting uipangesturerecognizer parameter passing nsdictionary. try passing gesture recognizer directly.

[revealcontroller performselector:@selector(revealgesture:) withobject: recognizer];
