Question

Here’s my code:

#define kDeselected .3
#define kSelected 1

- (void) selectButton:(UIImageView*)iconView{
    [iconView setAlpha:kDeselected];
    if(iconView.alpha == kDeselected){
        [iconView setAlpha:kSelected];
    }
    else if(iconView.alpha == kSelected){
        [iconView setAlpha:kDeselected];
     }
}

I’m a pretty advanced programmer but it’s beyond me as to why right before the if statement, when I manually went in and ensured that the if statement would result to true, it still doesn’t hit it.

It should be noted that when kDeselected = .5, then it works perfectly. When it’s .3 however…it doesn’t like me.

Try casting your const to a float value as #define kDeselected 0.3f
