   @implementation ViewController
   @synthesize keuze;
   - (IBAction)sliderValueChanged: (UISlider *)sender

   }

   - (void)viewDidLoad
   {
[super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.

keuzeArray = [NSArray arrayWithObjects:
              @"Koffie zwart", @"Koffie melk", @"Koffie melk&suiker", @"cafe au lait",               @"Koud water", @"Heet water", @"Chocomel", @"Wiener melange", nil];

   - (BOOL) shouldAutorotateToInterfaceOrientation:
   (UIInterfaceOrientation)InterfaceOrientation
   {
return (InterfaceOrientation != UIInterfaceOrientationPortraitUpsideDown);
   }

   @end

Answer 1

You are calling a object from your array that the index is not on your array.

Basically your array has 8 elements (0 to 7) and you are calling the index 8

Just change this line:

self.keuze.text = [keuzeArray objectAtIndex:(sender.value - 1)];

and it all should work
