Question

In my app I have a scrollview and when I press a button it is hidden when I press again it shows up.

I use scrollview.hidden = YES (or NO) to do it.

But I want to do it with an animation. For example, it may disappear from the bottom of the screen by moving and shows up with the same way. How can I do that?

edit:

[UIView beginAnimations:@"myAnimation" context:nil];
CGRect Frame = bottomScroller.frame;
if(Frame.origin.y == 380){
    Frame.origin.y = 460;
}else{
    Frame.origin.y = 380;
}
bottomScroller.frame = Frame;
[UIView commitAnimations];

This solved my problem…

You may check UIView animations. It’s pretty easy. For example to animate translation you may use something like:

[UIView beginAnimations:@"myAnimation" context:nil];
CGRect Frame = yourView.frame;
Frame.origin.y = 0;
yourView.frame = Frame;
[UIView commitAnimations];

Then to move it back:

[UIView beginAnimations:@"myAnimation" context:nil];
CGRect Frame = yourView.frame;
Frame.origin.y = 100;
yourView.frame = Frame;
[UIView commitAnimations];

Changes in frame, alpha and some other parameters will be automatically animated.
