If you want to execute code when the view appears (e.g. an animation), -viewDidLoad is the wrong place to do it.

You should probably use:

- (void)viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];
    // ...
}

Or viewWillAppear it sometimes makes the loading look a bit smoother – Matt Rees Oct 19 '12 at 09:34

Try in viewWillAppear

  -(void)viewWillAppear:(BOOL)animated
 {
  artext=[[NSMutableArray alloc] init];
  arimage=[[NSMutableArray alloc] init];
  arsound=[[NSMutableArray alloc] init];

  [self copysqlitetodocuments];
  [self Readthesqlitefile];   
  self.view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"classroom.png"]];

 }

When your viewDidLoad method is called, the controller isn't yet in the view hierarchy, so the animations doesn't work.

You have to perform animations in viewWillApper, after implementing the method [super viewWillAppear]. Something like:

- (void)viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];

    artext = [[NSMutableArray alloc] init];
    arimage = [[NSMutableArray alloc] init];
    arsound = [[NSMutableArray alloc] init];

    [self copysqlitetodocuments];
    [self Readthesqlitefile];   
    self.view.backgroundColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"classroom.png"]];

}

whether while back pop from other view it will show the animations huh? – iosdev Oct 19 '12 at 09:39
So you need an animation only the first time? – Marco Pace Oct 19 '12 at 09:40
So this code should give you a good example to how to implement that ;-) – Marco Pace Oct 19 '12 at 10:20
depends on your animation. You asked for a function that animates every time, not about the animation itself. Check it: http://stackoverflow.com/questions/2337408/addsubview-animation – Marco Pace Oct 19 '12 at 11:07
