UIButton sets dark when it is selected (I want to avoid this)

Question

I'm developing an iOS 4 application.

I'm using a custom uibutton to make an image clickable. When user taps over the image, it will disappear.

It's not very pretty to see that the image gets black, then turns to its original color, and then disappear.

Is there a way to disable that effect?

Answer 1

You will need to set the property adjustsImageWhenHighlighted to NO:

[button setAdjustsImageWhenHighlighted:NO];

Alternatively you can set the same image for all controlStates of the button.

Answer 2

You need to set the property Shows Touch On Highlight to enabled.

Programmatically you can do that with:

[button setShowsTouchWhenHighlighted:YES];
