I am trying to have multiple picker views in one single view in Objective-C. So far I have created 3 different textfields and I want three of them to have different picker views if I click on them. so let us say if click on textfield #1 it opens the array #1 and textfields #2 the second and textfields # third one. If i click the first and second text fields related picker view displaying but if i click the third one picker view is not showing.
