1. 如果用presentModalViewController,可以这样做：
- (IBAction)infoButtonPressed:(id)sender {
InfoViewController *infoViewController = [[InfoViewControlleralloc] initWithNibName: @"DAandPAInfo" bundle: [NSBundlemainBundle]];
self.modalTransitionStyle =UIModalTransitionStyleFlipHorizontal;
[self presentModalViewController: infoViewController animated:YES];
[infoViewController release];
}
2. 如果是pushViewController,则复杂一点
CATransition *transition= [CATransition animation];
transition.duration = 1.0f;
transition.timingFunction =[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
transition.type = @"reveal";
//@"cube" @"moveIn" @"reveal"@"fade"(default) @"pageCurl" @"pageUnCurl" @"suckEffect"@"rippleEffect" @"oglFlip" @“twist”
transition.subtype = kCATransitionFromTop;
//各种动画效果
transition.delegate = self;
[self.navigationController.view.layer addAnimation:transition forKey:nil];
TestViewController *next =[[TestViewController alloc] init];
[self.navigationController pushViewController:next animated:NO];
