ios - addtarget to a button in another view controller

Why doesn't this work? I want the closeBtn in the new view controller to call a method called dismiss: in the current view controller.

NewViewController *newVC = [[NewViewController alloc] initWithNibName:@"NewViewController" bundle:[NSBundle mainBundle]];

[newVC.closeBtn addTarget:self action:@selector(dismiss:) forControlEvents:UIControlEventTouchUpInside];

The dismiss: method is never called in the current view controller. closeBtn is correctly set up as a property in NewViewController and linked in the .xib file.

Create the object of the another controller and specify it in addTarget. Give the name of the method in the action parameter. i.e anotherController *obj; [button addTarget:obj action:@selector(MethodName) forControlEvents:UIControlEventTouchDown];

Generally, that is not a good way to deal with methods and UI elements.

However, you can do something like this, though it is ugly.

[yourButton addTarget:self action:@selector(yourButtonPressed:) forControlEvent:UITouchUpInside];

    - (void) yourButtonPressed:(id)sender {
    OtherVC* otherVC = [OtherVC alloc] initWithNibName@"NewViewController"] ...
    [otherVC theDesiredMethod];
   [otherVC release];
}

This works but is not really good you are probably better off moving the function into the proper VC.

Hope that helps.
