How to change the highlighted color of a UIButton? [duplicate]

Answer 1

In Swift, if you want to use a image for highlighted state, you can do this with UIButton:

if enabled {
 //highlighted state
     enableMicrophone.setImage(UIImage(named: "mic_on"), forState: .Highlighted)
 } else {
 //normal state
     enableMicrophone.setImage(UIImage(named: "mic_off"), forState: .Normal)    
}
