1. Making UI image to work as a button. 2. Making UI image to change it's color

  1. As I understand, UI buttons may only have rectangular or round-ish shapes. I have a set of images of different shapes (e.g. pants, t-shirt, beard etc.) and each of them should work as a button. How do I make UI Image to work as a button?

  2. Second question: how do I make mentioned UI images to change color. I'm building an app where you can describe your look using paper doll kinda tool ( https://www.behance.net/gallery/49171187/ICEBREAKER-(work-in-progress) ). You tap an element > it calls a keyboard where each key represents a color > after you tap a key and choose a color the element you've tapped before changes it's color accordingly.

Thank you ?

hi , for your first question:
there are 2 ways : first way : by drag button in your storyboard and change image background from utilities .

second way : You can add a UITapGestureRecognizer to the imageView .

  1. just write in the right search bar in utilities (gesture) and will appear first one (Tap Gesture Recognizer) and drag it into your Storyboard
  2. Ctrl-drag from the imageView to the gestureRecognizer (will find it near the view controller yellow circle in the bar of story board),
  3. Ctrl-drag from the gestureRecognizer to the Swift-file to make an IBAction
  4. You'll also need to enable (user interactions) and (multiple touch) on the UIImageView utilities ,
  5. write what u want to do with pressing the image view in IBAction function .

for second question : i think u can use same way with each key (u can make each key a button or imageView and write what u want to do in the action function to change the color of any thing u want like another button which u made it's @IBOutlet for it . i hope my answer is clear .

Thanks for your answer, Ahmet.

First solution works here. In the second question I meant how do I technically change the color. Of course there is a button and it calls an action. I've received an answer on stack overflow and will give it a try soon. Here is the thread http://stackoverflow.com/questions/42773692/1-making-ui-image-to-work-as-a-button-2-making-ui-image-to-change-its-color/42774160?noredirect=1#comment72666481_42774160

And here is another option http://stackoverflow.com/questions/31803157/how-to-color-a-uiimage-in-swift

ooh sorry i misunderstood the second question and here is 2 lines of code to solve this second question if u still not find the solution :)) swift 2

yourImageView.image = yourImageView.image!.imageWithRenderingMode(UIImageRenderingMode.AlwaysTemplate)
yourImageView.tintColor = UIColor.redColor()

swift 3

yourImageView.image = yourImageView.image!.withRenderingMode(.alwaysTemplate)
yourImageView.tintColor = UIColor.red

i tried this solution and it is worked perfect on arrow icon shape or triangle shape , here is a link for the solution too (http://stackoverflow.com/questions/19274789/how-can-i-change-image-tintcolor-in-ios-and-watchkit)
