Question

Hey guys! I have this little problem:

I have one ViewController which adds 2 subViews in my ViewController so I have something like this:

//in my viewController.m i have this:
- (void)startIcons
{
    IconHolder *newIconHolder = [[IconHolder alloc] initWithItem:@"SomeItenName"];
    [self.view addSubview:newIconHolder];
}
- (void)onPressIcon targetIcon(IconHolder *)pressedIcon
{
    NSLog(@"IconPressed %@", [pressedIcon getName]);
}

And this is my subclass touchs:

//And in my IconHolder.m i have this:
- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event 
{
    //Here i need to call the method onPressIcon from my ViewController
}

Now:
How can I do that? The best way is create a linkage in my constructor to save my ViewController? How am I supposed to do that?

Thanks!

Yes, you should create that link just like you suspected.

Simply add a member variable MyViewController* viewController to your view and set it up when you create the view. If you want to get clever, you can create it as a property.

Beware that you shouldn’t retain the viewController from a view though – the view is already retained by the controller and if you have a retain going the other way, you will generate a retain cycle and will cause a leak.
