Change colour of dark grey highlight when holding down custom UIButton?
You said you set a custom image for the UIControlStateHighlighted
state. This should disable the default behaviour.
If you still have problems you can disable this effect by setting the adjustsImageWhenHighlighted
property to NO
and use whatever custom effect you want.
If adjustsImageWhenHighlighted = NO is not working,set Button-Type to Custom (IB or programmatically).
Default Button-Type: System, changes behavior of highlighted button.
