OS X or iOS? What do you mean by “open the web view”? On a Mac, you generally open windows which contain a given view. On iOS, you segue to a view controller that contains the view.
Probably the correct approach involves setting an outlet to the view from the view controller:
1. Subclass the view controller that contains the view (if you aren’t already using a custom subclass).
2. Add an outlet to the view controller called (say) ‘browseAirports’. Since an an outlet is a kind of instance variable, it’s recommended to lowercase the first letter.
3. In the storyboard, drag a connection from the view controller’s outlet to the view itself.
4. Refer to the view in code as ‘myViewController.browseAirports’.
Of course, this means you need a reference to the view controller, if you don’t already have one. How you do that will depend on which platform you’re using.
I don’t think there’s any reasonable way to refer to a view *by name*, since views don’t really have names. You can refer to views by *tag* (a numeric identifier), or there are other ad-hoc things you could do, such as locate the view at a known place in your view hierarchy (and checking it’s of the correct view class), but an outlet is the normal way to do something like this.
