Answer 1

Rather than setting and using tags, you could just check if control is the left or right accessory view:

if (control == view.leftCalloutAccessoryView) {
    //handle left control tap...        
}
else
if (control == view.rightCalloutAccessoryView) {
    //handle right control tap...       
}
