i'd like to remove the else part but the following doesn't work:
-=-=-=-
if ((![currentDesktopBackgroundImage isEqualToString:firstPath]) ||
(![currentDesktopBackgroundImage isEqualToString:secondPath]))
{
//Go South
}
-=-=-=-
wtf?
Your two statements are not equivalent. In your first version, you go
north if either comparison is true, and south only if *both*
comparisons are false. In the second, you go south if *either*
comparison is false.
For the second statement to be equivalent to the first, it needs to
use && instead of ||.
