在pushViewController:animated:时使用非默认的页面转换特效
1. 首先要明确的是,不使用pushViewController的默认动画,所以在调用这个函数时,要将animated设置为NO.

2. 使用普通的来CATransition实现转换效果,代码如下:

    CATransition *animation = [CATransition animation];
    [animation setDuration:0.3];
    [animation setType: kCATransitionMoveIn];
    [animation setSubtype: kCATransitionFromTop];
    [animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionDefault]];
    [self.navigationController pushViewController:m_poseAddIssueViewController animated:NO];
    [self.navigationController.view.layer addAnimation:animation forKey:nil];
