Disabled UIButton not faded or grey

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?

thanks

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

Answer by Ravin for Disabled UIButton not faded or grey

You can use following code:

sendButton.enabled = YES;  sendButton.alpha = 1.0;    or    sendButton.enabled = NO;  sendButton.alpha = 0.5;

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, and use the Text Color popup button to change the text color. In code, use the -setTitleColor:forState: message.

(I realize this is an older post, but I thought others might like this option)

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.

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];

In Swift:

previousCustomButton.enabled = false  previousCustomButton.alpha = 0.5  

or

nextCustomButton.enabled = true  nextCustomButton.alpha = 1.0

#import "UIButton+My.h"  #import   @implementation UIButton (My)      -(void)fade :(BOOL)enable{      self.enabled=enable;//      self.alpha=enable?1.0:0.5;  }    @end  

.h:

#import   @interface UIButton (My)    -(void)fade :(BOOL)enable;    @end

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).

Answer by Ahmed R. for Disabled UIButton not faded or grey

just change state config to disable and choose what you want, background color OR background Image for disabled state

Answer by Mahesh Lad for Disabled UIButton not faded or grey

You can use adjustsImageWhenDisabled which is property of UIButton
(@property (nonatomic) BOOL adjustsImageWhenDisabled)

Ex:

 Button.adjustsImageWhenDisabled = false

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

Answer by AechoLiu for Disabled UIButton not faded or grey

If the UIButton is in the state combined with selected and disabled, it's state is UIControlStateSelected | UIControlStateDisabled.

So, it's state needs to adjust by

[button setTitleColor:color UIControlStateSelected | UIControlStateDisabled];  [button setImage:image forState:UIControlStateSelected | UIControlStateDisabled];

An approach is sub-class UIButton as following.

@implementation TTButton  - (void)awaeFromNib {     [super awakeFromNib];        //! Fix behavior when `disabled && 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
