Disabled UIButton not faded or grey

Question

In my iPhone app  I have a UIButton which I have created in Interface Builder  I can successfully enable and disable it like this in my code      sendButton enabled   YES    or  sendButton enabled   NO    However  the visual look of the button is always the same  It is not faded or grey  If I attempt to click it though  it is enabled or disabled as expected  Am I missing something  Shouldn t it look faded or grey

If you use a text button  you can put into viewDidLoad the instance method  -  void setTitleColor  UIColor   color forState  UIControlState state   example    self syncImagesButton setTitleColor  UIColor grayColor  forState UIControlStateDisabled

Another option is to change the text color  to light gray for example  for the disabled state   In the storyboard editor  choose Disabled from the State Config popup button  Use the Text Color popup button to change the text color   In code  use the -setTitleColor forState  message

If the UIButton is in the combined state of selected and disabled  its state is UIControlStateSelected   UIControlStateDisabled   So its state needs to be adjusted like this    button setTitleColor color UIControlStateSelected   UIControlStateDisabled    button setImage image forState UIControlStateSelected   UIControlStateDisabled       One approach is to subclass UIButton as follows    implementation TTButton -  void awakeFromNib       super awakeFromNib            Fix behavior when  disabled  amp  amp  selected          Load settings in  xib  or  storyboard   and apply it again      UIColor  color    self titleColorForState UIControlStateDisabled        self setTitleColor color forState UIControlStateDisabled        UIImage  img    self imageForState UIControlStateDisabled        self setImage img forState UIControlStateDisabled      -  void setTitleColor  UIColor   color forState  UIControlState state        super setTitleColor color forState state               if  UIControlStateDisabled    state             super setTitleColor color forState UIControlStateSelected   state            super setTitleColor color forState UIControlStateHighlighted   state            -  void setImage  UIImage   image forState  UIControlState state        super setImage image forState state        if  UIControlStateDisabled    state             super setImage image forState UIControlStateSelected   state            super setImage image forState UIControlStateHighlighted   state             end

Create an extension in Swift   3 0 rather than each button by itself  extension UIButton       override open var isEnabled   Bool           willSet              if newValue    false                   self setTitleColor UIColor gray  for  UIControlState disabled

This is quite an old question but there s a much simple way of achieving this   myButton userInteractionEnabled   false  This will only disable any touch gestures without changing the appearance of the button

Maybe you can subclass your button and override your isEnabled variable  The advantage is that you can reuse in multiple places    override var isEnabled  Bool        didSet            if isEnabled                self alpha   1            else                self alpha   0 2

I am stuck on the same problem  Setting alpha is not what I want   UIButton has  background image  and  background color   For image  UIButton has a property as   property  nonatomic  BOOL adjustsImageWhenDisabled     And background image is drawn lighter when the button is disabled  For background color  setting alpha  Ravin s solution  works fine   First  you have to check whether you have unchecked  disabled adjusts image  box under Utilities-Attributes  Then  check the background color for this button    Hope it s helpful  This is an old post  things might have changed in Xcode

User · Answer

You can use adjustsImageWhenDisabled which is property of UIButton     property  nonatomic  BOOL adjustsImageWhenDisabled   Ex    Button adjustsImageWhenDisabled   false

Try to set the different images for UIControlStateDisabled  disabled gray image  and UIControlStateNormal Normal image   so the button generate the disabled state for you

User · Answer

This question has a lot of answers but all they looks not very useful in case if you really want to use backgroundColor to style your buttons  UIButton has nice option to set different images for different control states but there is not same feature for background colors  So one of solutions is to add extension which will generate images from color and apply them to button   extension UIButton     private func image withColor color  UIColor  - gt  UIImage        let rect   CGRect x  0 0  y  0 0  width  1 0  height  1 0      UIGraphicsBeginImageContext rect size      let context   UIGraphicsGetCurrentContext        context  setFillColor color cgColor      context  fill rect       let image   UIGraphicsGetImageFromCurrentImageContext       UIGraphicsEndImageContext        return image        func setBackgroundColor   color  UIColor  for state  UIControlState        self setBackgroundImage image withColor  color   for  state          Only one issue with this solution -- this change won t be applied to buttons created in storyboard  As for me it s not an issue because I prefer to style UI from code  If you want to use storyboards then some additional magic with  IBInspectable needed   Second option is subclassing but I prefer to avoid this

You can use following code     sendButton enabled   YES  sendButton alpha   1 0   or  sendButton enabled   NO  sendButton alpha   0 5

User · Answer

It looks like the following code works fine  But in some cases  this doesn t work    sendButton enabled   NO  sendButton alpha   0 5    If the above code doesn t work  please wrap it in Main Thread   so   dispatch async dispatch get main queue           sendButton enabled   NO      sendButton alpha   0 5       if you go with swift  like this   DispatchQueue main async       sendButton isEnabled   false     sendButton alpha   0 5     In addition  if you customized UIButton  add this to the Button class    override var isEnabled  Bool       didSet           DispatchQueue main async               if self isEnabled                   self alpha   1 0                           else                   self alpha   0 5                                   Thank you and enjoy coding

To make the button is faded when disable  you can set alpha for it  There are two options for you   First way  If you want to apply for all your buttons in your app  so you can write extension for UIButton like this   extension UIButton        open override var isEnabled  Bool          didSet               alpha   isEnabled   1 0   0 5                      Second way  If you just want to apply for some buttons in your app  so you can write a custom class from UIButton like below and use this class for which you want to apply   class MyButton  UIButton       override var isEnabled  Bool           didSet               alpha   isEnabled   1 0   0 5

You can use the both first answers and is going to be a better result    In the attribute inspector  when you re selecting the button   change the State Config to Disabled to set the new Image that is going to appear when it is disabled  remove the marker in the Content- Enabled check to made it disabled     And when you change the state to enabled  the image will load the one from this state    Adding the alpha logic to this is a good detail
