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];
