How to change the background color of a UIButton while it s highlighted

Question

At some point in my app I have a highlighted UIButton  for example when a user has his finger on the button  and I need to change the background color while the button is highlighted  so while the finger of the user is still on the button    I tried the following    button backgroundColor    UIColor redColor     But it is not working  The color remains the same  I tried the same piece of code when the button is not highlighted and it works fine  I also tried calling -setNeedsDisplay after changing the color  it didn t have any effect   How to force the button to change the background color

Override highlighted variable  Adding  IBInspectable makes you edit the highlighted backgroundColor in storyboard  which is nifty too   class BackgroundHighlightedButton  UIButton        IBInspectable var highlightedBackgroundColor  UIColor       IBInspectable var nonHighlightedBackgroundColor  UIColor      override var highlighted  Bool           get               return super highlighted                   set               if newValue                   self backgroundColor   highlightedBackgroundColor                           else                   self backgroundColor   nonHighlightedBackgroundColor                           super highlighted   newValue

There is no need to override highlighted as computed property  You can use property observer to trigger background color change   override var highlighted  Bool       didSet           backgroundColor   highlighted   UIColor lightGrayColor     UIColor whiteColor             Swift 4  override open var isHighlighted  Bool       didSet           backgroundColor   isHighlighted   UIColor lightGray   UIColor white

You can subclass the UIButton and make a nice forState   colourButton h   import  lt UIKit UIKit h gt    interface colourButton   UIButton  - void setBackgroundColor  UIColor   backgroundColor forState  UIControlState state    end   colourButton m   import  colourButton h    implementation colourButton       NSMutableDictionary  colours     - id initWithCoder  NSCoder   aDecoder       self    super initWithCoder aDecoder           If colours does not exist     if  colours                colours    NSMutableDictionary new       The dictionary is used to store the colour  the key is a text version of the ENUM         colours  NSString stringWithFormat    lu   UIControlStateNormal      UIColor  self backgroundColor      Store the original background colour            return self     - void setBackgroundColor  UIColor   backgroundColor forState  UIControlState state          If it is normal then set the standard background here     if state  amp  UIControlStateNormal                 super setBackgroundColor backgroundColor                 Store the background colour for that state     colours  NSString stringWithFormat    lu   state    backgroundColor     - void setHighlighted  BOOL highlighted          Do original Highlight      super setHighlighted highlighted           Highlight with new colour OR replace with orignial     if  highlighted  amp  amp  colours  NSString stringWithFormat    lu   UIControlStateHighlighted                  self backgroundColor   colours  NSString stringWithFormat    lu   UIControlStateHighlighted              else               self backgroundColor   colours  NSString stringWithFormat    lu   UIControlStateNormal             - void setSelected  BOOL selected          Do original Selected      super setSelected selected           Select with new colour OR replace with orignial     if  selected  amp  amp  colours  NSString stringWithFormat    lu   UIControlStateSelected                  self backgroundColor   colours  NSString stringWithFormat    lu   UIControlStateSelected              else               self backgroundColor   colours  NSString stringWithFormat    lu   UIControlStateNormal              end   Notes  This is an example  I know there are problems and here are some   I have used an NSMutableDictionay to store the UIColor for each State  I have to do a nasty text conversion for the Key as the UIControlState is not a nice straight Int   If it where you could init an Array with that many objects and use the State as an index   Because of this you many have difficulties with e g  a selected  amp  disabled button  some more logic is needed   Another problem is if you try and set multiple colours at the same time  I have not tried with a button but if you can do this it may not work    btn setBackgroundColor colour forState UIControlStateSelected  amp  UIControlStateHighlighted     I have assumed this is StoryBoard  there is no init  initWithFrame so add them if you need them

in Swift 5  For those who don t want to use colored background to beat the selected state   Simply you can beat the problem by using  Selector  amp  if statement to change the UIButton colors for each state individually easily  For Example       override func viewDidLoad         super viewDidLoad       self myButtonOutlet backgroundColor   UIColor white    to reset the button color to its original color   optionally       IBOutlet weak var myButtonOutlet  UIButton       didSet      Button selector and image here         self myButtonOutlet setImage UIImage systemName       for  UIControl State normal           self myButtonOutlet setImage UIImage systemName   checkmark    for  UIControl State selected             self myButtonOutlet addTarget self  action   selector tappedButton   for  UIControl Event touchUpInside            objc func tappedButton         Colors selection is here     if self myButtonOutlet isSelected    true            self myButtonOutlet isSelected   false         self myButtonOutlet backgroundColor   UIColor white                else           self myButtonOutlet isSelected   true          self myButtonOutlet backgroundColor   UIColor black         self myButtonOutlet tintColor00   UIColor white

In Swift you can override the accessor of the highlighted  or selected  property rather than overriding the setHighlighted method  override var highlighted  Bool           get               return super highlighted                   set               if newValue                   backgroundColor   UIColor blackColor                             else                   backgroundColor   UIColor whiteColor                             super highlighted   newValue

Not sure if this sort of solves what you re after  or fits with your general development landscape  but the first thing I would try would be to change the background colour of the button on the touchDown event   Option 1   You would need two events to be capture  UIControlEventTouchDown would be for when the user presses the button  UIControlEventTouchUpInside and UIControlEventTouchUpOutside will be for when they release the button to return it to the normal state  UIButton  myButton     UIButton buttonWithType UIButtonTypeCustom    myButton setFrame CGRectMake 10 0f  10 0f  100 0f  20 f     myButton setBackgroundColor  UIColor blueColor     myButton setTitle   click me   forState UIControlStateNormal    myButton setTitle   changed  forState UIControlStateHighlighted    myButton addTarget self action  selector buttonHighlight   forControlEvents UIControlEventTouchDown    myButton addTarget self action  selector buttonNormal   forControlEvents UIControlEventTouchUpInside     Option 2   Return an image made from the highlight colour you want  This could also be a category      UIImage   imageWithColor  UIColor   color      CGRect rect   CGRectMake 0 0f  0 0f  1 0f  1 0f      UIGraphicsBeginImageContext rect size      CGContextRef context   UIGraphicsGetCurrentContext        CGContextSetFillColorWithColor context   color CGColor       CGContextFillRect context  rect       UIImage  image   UIGraphicsGetImageFromCurrentImageContext       UIGraphicsEndImageContext        return image      and then change the highlighted state of the button    myButton setBackgroundImage  self imageWithColor  UIColor greenColor   forState UIControlStateHighlighted

To solve this problem I created a Category to handle backgroundColor States with UIButtons  ButtonBackgroundColor-iOS  You can install the category as a pod    Easy to use with Objective-C   property  nonatomic  strong  UIButton  myButton         self myButton bbc backgroundColorNormal  UIColor redColor                   backgroundColorSelected  UIColor blueColor      Even more easy to use with Swift   import ButtonBackgroundColor       let myButton UIButton   UIButton type  Custom   myButton bbc backgroundColorNormal UIColor redColor    backgroundColorSelected  UIColor blueColor      I recommend you import the pod with   platform  ios   8 0  use frameworks   pod  ButtonBackgroundColor      gt  1 0    Using use frameworks  in your Podfile makes easier to use your pods with Swift and objective-C   IMPORTANT  I also wrote a Blog Post with more information
