title: How do I use a switch statement to find if a UIButton is pressed?
body: <p>I’m making an ios application and am having trouble using a switch statement to see if a UIButton element was pressed.
  This is who I want the end product to work: I have multiple uncolored images (by uncolored I mean white, a UIImage). When an uncolored image is tapped a subview opens with colored boxes (UIButtons, 24 of them, each with individual colors.). When a colored box button is selected and the back button on the toolbar is pressed, the subview closes and the original view re-appears with the uncolored image (the one selected to open the subview) now colored with the desired color selected in the subview.</p>
  
  <p>I want to use a switch statement to find which uncolored image and which color was selected (all UIButton elements). I do not know what to put as an expression in the switch statement because I’m dealing with UIButtons. The rest of the switch statement compares the value of the UIButton element to see if it’s equal to YES (when the button is pressed), and if it is, it returns a string. I also want to know how to connect an IBAction to a UIImage (so when the images are tapped a subview opens). </p>
