实现pushViewController:animated:的不同页面转换特效

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:nill];
