iPhone中下载view视图的问题

Question

 (void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated

上面的代码实现从左侧下载视图，怎么样从右侧下载视图？

Answer 1

CATransition *animation = [CATransition animation];
[[self navigationController] pushViewController:elementController animated:NO];
[animation setDuration:0.45];
[animation setType:kCATransitionPush];
[animation setSubtype:kCATransitionFromLeft];
[animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionDefault]];
[[elementController.view layer] addAnimation:animation forKey:@"SwitchToView1"];

还需要添加#import <QuartzCore/QuartzCore.h>
