Crystal Ball extra credit

For the adding UIcolor array extra credit assignment, I have now managed to get a successful build without any errors, but when I press the predict button the color of the text does not change. What am I missing? Here is what I have: Interface page#import <UIKit/UIKit.h>

@interface SDViewController : UIViewController @property (strong, nonatomic) IBOutlet UILabel *predictionLabel; @property (strong, nonatomic) NSArray *predictions; @property (strong, nonatomic) NSArray *colorsArray;

• (IBAction)buttonPressed;

@end Implementation page#import <UIKit/UIKit.h>

@interface SDViewController : UIViewController @property (strong, nonatomic) IBOutlet UILabel *predictionLabel; @property (strong, nonatomic) NSArray *predictions; @property (strong, nonatomic) NSArray *colorsArray;

• (IBAction)buttonPressed;

@end@implementation SDViewController

• (void)viewDidLoad { [super viewDidLoad];

  self.predictions = [[NSArray alloc] initWithObjects: @"It is Certain", @"It is Decidedly So", @"All signs say YES", @"The Stars are not aligned", @"My reply is no", @"It is doubtful", @"Better not tell you now", @"Concentrate and ask again", @"Unable to answer now", @"Maybe, yes", nil];

  self.colorsArray = [[NSArray alloc] initWithObjects: @"Red", @"Blue", @"Green", @"Purple", nil];

}

• (void)didReceiveMemoryWarning { [super didReceiveMemoryWarning]; // Dispose of any resources that can be recreated. }

• (IBAction)buttonPressed { int random = arc4random_uniform(self.predictions.count); self.predictionLabel.text = [self.predictions objectAtIndex:random];

}

@end
