Question

How to reach UIViewcontrols method from subview?

Answer 1

A:

[yourButton addTarget:ViewController1 action:@selector(method1) forControlEvents:UIControlEventTouchUpInside];

You should keep a reference of the ViewController1 in the UIView inherited class. If you do not have a class for the UIView, and you do all the work in the ViewController1 class it would be:

[yourButton addTarget:self action:@selector(method1) forControlEvents:UIControlEventTouchUpInside];

I have a class for UIView. i will use (add) it to my 3 different viewconrollers. you say addTarget:ViewController1, how do i know that button pressed in which uiviewcontroller? it can be ViewControler1 or 2 or 3.

Are you trying to add the same instance of the view to the three differents viewControllers? If so, It is not possible according to the Apple doc. Views can have only one superview.If the instances of the views are different you could add a ViewController property in the UIView class set to the one in wich the UIview is.

yes, i want to create instances of the UIView (it has 3 buttons) for each ViewControls, i think i should add it with addsubview method.let me explain simple: all ViewController has a method named sayHello. and there is one UIView that has 3 buttons. i want to add an instance of UIView to all 3 ViewControllers. when i create an instance for UIViewController1, i want to send a varible to UIView. 3 buttons' tag should be 1, 2, 3. and when i press the buttons (on instance of uiview in viewcontroller1), how can i write [sender tag] to Label in ViewController1? same thing for other ViewControllers.

is it so hard or apple doesnt allow it?

tester 2010-08-28 12:28:15

if you do like this:[yourButton addTarget:ViewController1 action:@selector(method1:) forControlEvents:UIControlEventTouchUpInside];And declare the method1: - (void) method1:(id)sender{...}you are sending the pressed button as the first argument of the method.
