iPhone subview flip between 2 views

iPhone / Objective-C

On my vi开发者_JAVA技巧ew a little "hover" view appears after a user clicks on a button on the main view. When the user clicks this subview I want the subview to FlipFromRight to another view (same size). The main view underneath should stay.

viewHot and viewCold are the subviews viewMain is the main one.

Is this possible?

Create another empty view in viewMain called viewHover and position it where you want the hover views to show. Then in IB add either viewHot or viewCold (not both) as a subview of viewHover.

Then call a method like this to flip the views:

-(void)flipViews
{
    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:1.0];  
    [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight forView:viewHover cache:YES];

    if ([viewHot superview])
    {
        [viewHot removeFromSuperview];
        [viewHover addSubview:viewCold];
        [viewHover sendSubviewToBack:viewHot];
    }
    else
    {
        [viewCold removeFromSuperview];
        [viewHover addSubview:viewHot];
        [viewHover sendSubviewToBack:viewCold];
    }

    [UIView commitAnimations];
}
