How can I make slide down transition animation?

Question

I can see a lot of transition animation: from left to right, right to left, fading, but how can I make transition from the top down to bottom?

Thanks for all help

Try working out this... Add QuartzCore framework

#import <QuartzCore/QuartzCore.h>

CATransition *transDown=[CATransition animation];
[transDown setDuration:0.5];
[transDown setType:kCATransitionPush];
[transDown setSubtype:kCATransitionFromBottom];
[transDown setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];

[Boottom_view.layer addAnimation:transDown forKey:nil];

[[self navigationController] presentModalViewController:modalViewController animated:YES];

and hiding it like this:

[self.navigationController dismissModalViewControllerAnimated:YES];

Your could use Core Animation, what sort of object are you using?

Basically, to fade in an object you do this:

[[objectName animator] setOpacity: 1];

Remember you first need to set the opacity to 0 etc. before the animation begins. Hope this is what your wanting.

You set your view frame to it's starting position offscreen and then your bring your frame into position with some animation.

CGRect originalFrame = [detailsView frame];
CGRect offscreenFrame = originalFrame;
offscreenFrame.origin.y -= offscreenFrame.size.height; 
detailsView.frame = offscreenFrame;  //Send the frame above screen        

//Add view here if necessary to an unscrew view
// [aSuperView addSubview:detailsView];

[UIView beginAnimations:@"BringIn" context:nil];
[UIView setAnimationDuration:.3];
[UIView setAnimationDelegate:self];
[UIView setAnimationCurve:UIViewAnimationCurveEaseIn];
detailsView.frame = originalFrame
[UIView commitAnimations];
