TouchesBegan on a Sub-ViewController not getting called

I have a ViewController that responds to some touchEvents (touchesBegan, touchesMoved, etc...).

I've found that when I show this controller using presentModalViewController: it works just fine, but I'm trying to add it's View as a subview of another ParentViewController like so:

- (void)viewDidLoad
{
    [super viewDidLoad];

    //Add Su开发者_开发百科bController
    controller = [[SubViewController alloc] initWithNibName:@"SubViewController" bundle:nil];
    controller.view.frame = CGRectMake(0, 30, 300, 130);
    [view addSubview:controller.view];
    [controller release];
}

When I do this, it gets added the parent view but it no longer responds to touch events. Is there a way to fix this?

Also, is there a better way to go about this? I know I probably could have used a View subclass for the child view, but it's supposed to use a Nib and I wasn't sure how to handle that without using a ViewController.

You're correct you should use a UIView subclass.

The easiest way to load it from a nib is to include the subview in your nib.

• Just drop a UIView into the view connected to the original view controller.

• Then with the view inside selected go to the identity inspector. It's the one that looks like a little ID card.

• The very first field is called Custom Class.

• Type the name of your UIView subclass here.

If you need a reference to this just create an IBOutlet in your original view controller and hook it up. That way you can set hidden = YES until you need it.

In your UIView subclass you might want to override

- (void)awakeFromNib This will get called when the nib first unpacks.

for setting up any gesture recognizers, etc.

To load a nib directly into a view :

// Get the views created inside this xib
NSArray *views = [NSBundle mainBundle] loadNibNamed:@"myViewNib" owner:nil];

// There's probably only one in there, lets get it
UIView *myView = [views objectAtIndex:0];

// Do stuff . . .
[[self view] addSubview:myView];

You could try to call becomeFirstResponder in your subview and see whether it receives touchesBegan... It is probably so, but it will also possibly make the superview not receive touchesBegan if you require it...
