Question

I have a popover view which is called with:

Info *infoview = [[Info alloc]init];
pop = [[UIPopoverController alloc]initWithContentViewController:infoview];
[pop setDelegate:self];
[pop presentPopoverFromRect:CGRectMake(-60, 30, 400, 400) inView:bigMenuView permittedArrowDirections:UIPopoverArrowDirectionDown animated:YES];
[infoview release];

In this popoverview is (see in the code) an info.xib which has some UIBUttons.

Now I want to change something. in my “mainview” after I click on the Button.

Note: I can access my IBAction Method in the “First Responder” but the is no action.

Answer 1

In order to do what you want, declare a property on the button in Info, something like :

@property(retain) IBOutlet UIButton *myButton;

Now synthesize it, in implementation part. In order for the button to send the correct action to the correct target, you should do like :

Info *infoview = [[Info alloc]init];
// set the action/target here
[infoView.myButton addTarget:bigMenuView
                      action:@selector(theSELYouWant)
            forControlEvents:UIControlEventTouchUpInside];
pop = [[UIPopoverController alloc] initWithContentViewController:infoview];
[pop setDelegate:self];
[pop presentPopoverFromRect:CGRectMake(-60, 30, 400, 400)
                     inView:bigMenuView
   permittedArrowDirections:UIPopoverArrowDirectionDown animated:YES];
[infoview release];

I supposed that the main view is bigMenuView.
This will make the button sending a theSELYouWant message to bigMenuView each time it is touched.
