copied!<p>There's going to be a penalty each time you load a new view, you could attempt to consolidate screens using a scroll view or a different layout. Also, if you are loading any unnecessary graphics you may want to remove them.</p> <p>You could also add each view as a subview yourself in which case you have control over the animation duration among other things. This code will do that for you, although beware as I just wrote it and did not test it (The transition style and boolean parameters can be removed as they do nothing right now).</p> <p>UIViewControllerExtendedPresentModalViewController.h</p> <pre><code>#import <Foundation/Foundation.h> typedef enum _ExtendedModalTransitionStyle { ExtendedModalTransitionStyleTopDown } ExtendedModalTransitionStyle; @interface UIViewController ( ExtendedPresentModalViewController ) - (void)presentModalViewController: (UIViewController*)modalViewController withTransitionStyle: (ExtendedModalTransitionStyle)style animated: (BOOL)animated; - (void)dismissModalViewController: (UIViewController*)modalViewController withTransitionStyle: (ExtendedModalTransitionStyle)style animated: (BOOL)animated; @end </code></pre> <p>UIViewControllerExtendedPresentModalViewController.m</p> <pre><code>#import "UIViewControllerExtendedPresentModalViewController.h" #import <QuartzCore/QuartzCore.h> @implementation UIViewController ( ExtendedPresentModalViewController ) - (void)presentModalViewController: (UIViewController*)modalViewController withTransitionStyle: (ExtendedModalTransitionStyle)style animated: (BOOL)animated { [modalViewController retain]; // we'll need this for a little while, hang on to it.
