Open view with slide effect from bottom to top on iPhone

Question

Hi all!

I'm making an application for iPhone (which runs in landscape mode) (OS 3.0), and I want that when I touch a toolbar button it opens a view with a slide effect (similar to the effect when you touch 'Bookmarks' in Mobile Safari's toolbar) from the bottom to the top of the screen. The view is in the same XIB file as the button.

How can I do this?

Thanks in advance.

Answer 1

[self.tabBarController presentModalViewController:yourSlideController animated:YES];

Answer 2

If you are asking about doing the animation custom here's a snippet that might help. Lets assume the view "myView" is already added as a subview to the current view.

[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];

The important numbers in there are the y positions in the setFrame rect (480 then 0), this moves it from offscreen to onscreen.

I wrote a short tutorial on how to slide views into place, you might find this helpfu:
