    The touches parameter is a set of UITouch instances, which have a corresponding view property:

    The value of the property is the view object in which the touch originally occurred.

    UIViews don't have a specific name, but you can just check for their identity, i.e.:

    if([touch view] == aaaview) {}
    

    or use - (BOOL)isEqual:.

    You could also use the tag property instead to give them meaningful identities:

    enum MyViews {
        AaaView,
        // ...
    };
    
    aaaview.tag = AaaView;
    
    // ...
    if([touch view].tag == AaaView) {}
    

    If you really need names for some reason not mentioned in the question, you could subclass UIView and introduce a name property.
