UINavigationContorller 视图切换

实现UINavigationController视图切换

- (void)dismissModalViewControllerAnimated:(BOOL)animated
- (void)presentModalViewController:(UIViewController *)modalViewController animated:(BOOL)animated

- (void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated
- (UIViewController *)popViewControllerAnimated:(BOOL)animated
这4个方法，两两对应，前2个是上下推，后面2个是左右推

 

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:nil];
