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"]];
}
