I want my UIButton to show up the highlighted state when I click over a button that is already selected.
Basically in the highlighted state I apply a *.png image as my UIButton backgroundImage to give a pressed down effect.
But if the button is already in the Selected State When I click over it again I just can't see the highlighted state but it goes straight to the normal state!
Watch the Issue--> Video of the Issue!
Help please
//0 init UIButton
UIButton *button = [[UIButton alloc] initWithFrame:CGRectMake(x, y, aSide, aSide)];
//1 Give it a backgroundColor
[button setBackgroundColor:aColor];
[..]
//2 Set titleLabel and its style
[button setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
[button setTitleColor:[UIColor redColor] forState:UIControlStateSelected];
[button setTitleColor:[UIColor grayColor] forState:UIControlStateHighlighted];
UIImage *shadowImage = [UIImage imageNamed:kBtnShadow];
shadowImage = [shadowImage stretchableImageWithLeftCapWidth:floorf(shadowImage.size.width/2) topCapHeight:floorf(shadowImage.size.height/2)];
[button setBackgroundImage:shadowImage forState: UIControlStateHighlighted];
[button setTitle:aLabel forState: UIControlStateNormal];
//3 Assign tag and Action
[button setTag:tag];
[button addTarget:target action:a forControlEvents:UIControlEventTouchUpInside];
The various states: UIControlStateNormal
, UIControlStateSelected
, and (UIControlStateSelected | UIControlStateHighlighted)
are all actually distinct. If you want your shadowImage
to apply both in the (only) highlighted state and in the highlighted+selected state, you must also set:
[button setBackgroundImage:shadowImage forState:(UIControlStateHighlighted | UIControlStateSelected)]
