Hello,

Following is the code I used from iPhone development learning and ran it on the simulator. Now the problem i get is that after the first event of shake the prediction is totaly blank all i see is the background image. Although I have followed all the steps as it is - can somebody be kind enough to point out the mistake. Thanks in advance

import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController @synthesize predictionLabel; @synthesize predictionArray;

• (void)viewDidLoad { [super viewDidLoad];

  UIImage *image = [UIImage imageNamed: @"dc-crystal-ball.jpg"]; UIImageView *imageView =[[UIImageView alloc] initWithImage:image]; [self. view insertSubview:imageView atIndex:0];

self.predictionArray = [[NSArray alloc] initWithObjects:@"It is decideley so", @"good things coming", @"Good time is here", @"Great profit", @"stay possitive",@"Stay Foccused",@"all is well",nil];

// Do any additional setup after loading the view, typically from a nib.

}

• (void)viewDidUnload { [self setPredictionLabel:nil]; [self setPredictionLabel:nil]; [self setPredictionLabel:nil]; [self setPredictionLabel:nil]; [super viewDidUnload]; // Release any retained subviews of the main view. }

• (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation { return (interfaceOrientation != UIInterfaceOrientationPortraitUpsideDown); } -(void) makePrediction{

  NSUInteger index = arc4random_uniform(self.predictionArray. count);

  self.predictionLabel.text = [self.predictionArray objectAtIndex: index]; }

-(BOOL)canBecomeFirstResponder{ return YES; }

-(void) motionBegan:(UIEventSubtype)motion withEvent:(UIEvent *)event{ self.predictionLabel.text = @""; } -(void) motionEnded:(UIEventSubtype)motion withEvent:(UIEvent *)event{ if(motion == UIEventSubtypeMotionShake){ [self predictionLabel]; } } -(void) motionCancelled:(UIEventSubtype)motion withEvent:(UIEvent *)event{ NSLog(@"Motion Cancelled"); } -(void) touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{ self.predictionLabel.text = @""; } -(void) touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event{ [self predictionLabel];

}
