How to disable a button with an image without decreasing alpha in obejective C?

Question

After creating a round rectangular button, I turned off the button, and the button alpha remains at 1 unless I manually reduced the alpha to 0.5. But after inserting the image on the button, the alpha of the button will be automatically set to 0.5, even after setting alpha-1 after turning off the button.

I would like to disable the button containing the image without affecting it.

Can anybody help me?

Answer 1

Look at the property UIButton adjustsImageWhenDisabled. Setting that NO should do what you want.

There is also a similar property for highlighted buttons.

xib.

Answer 3

Yes, the adjustsImageWhenDisabled property and setting its NO is the way to go.
