Question

If ViewController‘s view is set to MyView

And ViewController maintains a pointer to it’s view (set up via storyboards)

@property (weak, nonatomic) IBOutlet MyView *v;

Where in ViewController, should the following take place?

UIPanGestureRecognizer *panGesture = [[UIPanGestureRecognizer alloc] 
             initWithTarget:v action:@selector(pan:)];
[v addGestureRecognizer: panGesture];

Answer 1

viewDidLoad is a good place for this kind of initialization, since the view hierarchy will have been loaded into memory at that point, whether it was loaded from a storyboard or nib, or created programmatically.
