IOS - UIView animation on iPad, changing x origin and width at the same time?

Question

I'm having trouble animating UIView on iPad.

I am working on a project in which I implemented the facebook style menu on the left using the JTRevealSidebar framework .

This structure works fine, however, instead of “pushing” the right side view from the screen, I would like to resize it so that the user can still see all the contents in the right view.

I managed to do this by changing the view frame, as well as performing an offset.

This is what looks like a sidebar:

And when it is closed:

( , ), UIWebView.

, , - ( ):

, , , , :

webview ( , "done" ).

:

- (void)revealSidebar:(BOOL)shouldReveal {

    if (shouldReveal) {

        [UIView beginAnimations:@"" context:nil];
        [UIView setAnimationDuration:0.3];

        // Push the view to the right
        contentView.transform = CGAffineTransformTranslate(contentView.transform, CGRectGetWidth(sidebarView.frame), 0);

        // Resize the view so it fits on remaining part of the screen
        contentView.frame = CGRectMake(contentView.frame.origin.x, contentView.frame.origin.y, contentView.frame.size.width-sidebarView.frame.size.width, contentView.frame.size.height);


        // The problem is here: the view frame is changed before the
        // Translate transformation actualy starts...
        //
        // Is there a way to change the x origin and the width simultaneously ?

        [UIView commitAnimations];


    } else {
        [UIView beginAnimations:@"" context:nil];
        [UIView setAnimationDuration:0.3];

        // Reset the frame so that it takes up whole screen
        contentView.frame = CGRectMake(contentView.bounds.origin.x,contentView.bounds.origin.y,contentView.frame.size.width+sidebarView.frame.size.width,contentView.frame.size.height);

        [UIView commitAnimations];
    }

    _state.isShowing = shouldReveal ? 1 : 0;
}
