Here's what I've tried:
IBOutlet UIScrollView *scrollView; // created & placed on GUI with IB
@synthesize scrollView; // hooked up from w/in IB
- (void)viewDidLoad {
[super viewDidLoad];
imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"default.png"]];
[scrollView addSubview:imageView];
return;
}
The UIScrollView & UIImageView show up on the GUI, with the correct image, but gestures are ignored. What am I overlooking?

Put it in a UIScrollView.
