objective c - How can I pass a parameter when initializing a UIViewController? -

-

i have 2 controllers, first- , secondviewcontroller. want share methods of firstviewcontroller use them in secondviewcontroller.

this how create secondviewcontroller in firstviewcontroller:

sms = [[secondviewcontroller alloc] init]; uinavigationcontroller *navcontroller = [[uinavigationcontroller alloc]                                              initwithrootviewcontroller:sms];  [self presentmodalviewcontroller:navcontroller animated:yes];

i thought of passing current instance of firstviewcontroller secondviewcontroller extends uiviewcontroller. default initwithnibname method of secondviewcontroller called.

how achieve in objective-c?

im not sure understand problem... part of issue has how instantiating secondviewcontroller... posting code help.

but answer question have asked it.... "how pass firstviewcontroller secondviewcontroller"...

in secondviewcontroller.h create own init method

-(id) initwithfirstviewcontroller:(uiviewcontroller *)thefirstviewcontroller;

and in .m file... 

-(id) initwithfirstviewcontroller:(uiviewcontroller *)thefirstviewcontroller {   self = [super initwithnibname:@"mynibname" bundle:nil];   self.firstviewcontroller = thefirstviewcontroller; //this assumes have created property.  also, not retain first view controller or circular reference , secondviewcontroller leak.    return self;  }

then.. , here key.. make sure calling correct init method instantiate secondviewcontoller

secondviewcontroller *svc = [[secondviewcontroller alloc]initwithfirstviewcontroller:self];

now.. having said that.. looking @ rating, have feeling knew this.. , real question may be... why initwithnibname being called when not calling explicitly?

so i've got simple form in canvas / iframe facebook app, , i'm trying pass along values post. reading on s.o. , fb's latest docs, understand it, data send via post form can accessed on receiving end $_request object. i read on thread on s.o. in order post forms work need pass along input named "signed_request" value current signed_request (i have signed request working ok otherwise...all login , authentication stuff working fine). isnt mentioned anywhere in official fb docs. so problem comes in $_request object signed request, , bunch of other session stuff. form inputs found. the way can read them set method of form "request" isn't real form method. takes of inputs , sends them args in url. horrible. here's sample page canvas app form i'm using try debug (leaving out authentication stuff): <form enctype="application/x-www-form-urlencoded" method="post" target="_top" id="my_form" action=...
