Open view with slide effect from top to bottom on iPhone

I'm making an application for iPhone, and I want that when I touch a button it opens a view with a slide effect when you touch from the top to the bottom of the screen. The view is in the same XIB file as the button...Advance thanks

you need that use bellow code with your requirement simple with GestureRecognizer

- (void)viewDidLoad
{

    CATransition *animation = [CATransition animation];
    [animation setDelegate:self];   
    [animation setType:kCATransitionFade];
    [animation setDuration:0.5];
    [animation setTimingFunction:[CAMediaTimingFunction functionWithName:
                                  kCAMediaTimingFunctionEaseInEaseOut]];
    [[self.view layer] addAnimation:animation forKey:kAnimationKey];

    UISwipeGestureRecognizer *swipeGesture = [[[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(addCustomBottomBar)] autorelease];
    swipeGesture.numberOfTouchesRequired = 1;
    swipeGesture.direction = (UISwipeGestureRecognizerDirectionDown);
    [yourDownViewController.view addGestureRecognizer:swipeGesture];
    UISwipeGestureRecognizer *swipeGestureTop = [[[UISwipeGestureRecognizer alloc] initWithTarget:self action:@selector(addCustomBottomBar)] autorelease];
    swipeGestureTop.numberOfTouchesRequired = 1;
    swipeGestureTop.direction = (UISwipeGestureRecognizerDirectionUp);
    [yourUpViewController.view addGestureRecognizer:swipeGestureTop];
 }

here you just set frame on of your this viewcontroller in addCustomBottomBar method like bellow...

-(void)addCustomBottomBar{

    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:0.5];
    [UIView setAnimationTransition:UIViewAnimationTransitionNone forView:self.window cache:YES];


    yourUpViewController.view.frame=CGRectMake(0, 430, 320, 70);//here you can also switch two ViewWith some flag otherwise create another method for anotherView....

    [UIView commitAnimations];
}

2.if you want to Animation with up the ViewController with button Click then use bellow code.....

-(void)btnClicked{

    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:0.5];
    [UIView setAnimationTransition:UIViewAnimationTransitionNone forView:self.view cache:YES];

    if (yourflag) {

       yourViewController.view.frame=CGRectMake(0, 430, 320, 70);
    }
    else{
        yourflag=YES;
        yourViewController.view.frame=CGRectMake(0, 210, 320, 270);
        [self.view bringSubviewToFront:yourViewController.view];
    }
    [UIView commitAnimations];
}

hope,this help you..... :)

You can try this simple animation -

UIView *myView = [[UIView alloc] initWithFrame:self.view.frame];
myView.backgroundColor = [UIColor blueColor];
[self.view addSubview:myView];

[myView setFrame:CGRectMake(0, 480, 320, 480)];
[myView setBounds:CGRectMake(0, 0, 320, 480)];

[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:1.0];
[UIView setAnimationDelegate:self];
[myView setFrame:CGRectMake(0, 0, 320, 480)];
[UIView commitAnimations];
