pushViewController自定义动画

实现的主要代码如下：

CATransition *transition = [CATransition animation];
transition.duration = 1.0f;
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
transition.type = @"cube";
transition.subtype = kCATransitionFromRight;
transition.delegate = self;
[self.navigationController.view.layer addAnimation:transition forKey:nil];

FirstViewController *firstViewController = [[DemoViewController alloc]init];
[self.navigationController pushViewController: firstViewController animated:YES]; 

其中的动画类型有：

            animation.type = kCATransitionFade;

            animation.type = kCATransitionPush;
  
            animation.type = kCATransitionReveal;

            animation.type = kCATransitionMoveIn;

            animation.type = @"cube";
 
            animation.type = @"suckEffect";

            // 页面旋转
            animation.type = @"oglFlip";

            //水波纹
            animation.type = @"rippleEffect";

            animation.type = @"pageCurl";

            animation.type = @"pageUnCurl";

            animation.type = @"cameraIrisHollowOpen";

            animation.type = @"cameraIrisHollowClose";

返回按钮的动画实现事件

    // 修改导航栏的 左边的标题
    self.navigationItem.leftBarButtonItem=[[UIBarButtonItem alloc] initWithTitle:@"返回" style:UIButtonTypeRoundedRect target:self action:@selector(back)];
