Answer 1

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];
    // ...
}

Answer 2

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"]];

 }

Answer 3

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"]];

}
