/** One More Application
Imagine that you were creating a lottery application (or more likely, a lottery view within another application). You might have 10 views, each with a number, and you highlight each image as a number is drawn. In this case, you’d probably have ten instance variables, maybe named numberView1, numberView2, all the way to numberView10. To light up the views, you could have a large if…else or switch block, comparing the new value to all the values 1–10:
**/
int nextNum = arc4random() % 10 } 1;	// Random number generator, 1–10
    switch (nextNum) {
        case 1:
            // Highlight
            break;
        // etc.
    }
// Knowing KVC though, there is a more elegant solution:

[[self valueForKey:[NSString stringWithFormat:@“numberView%d”, nextNum]] highlight];	// Assume highlight method exists and works
