从底部加载导航ViewController

Question

我有四个ViewControllers,其中ViewControllers使用UINavigationController.我可以逐个切换到每个ViewController.

问题是,因为我使用的是NavigationController,所有的ViewControllers都是从Left或Right加载的.但我想从底部加载ViewController.我知道我可以使用presentModalViewController从底部呈现ViewController.但它不等同于导航控制器,因为从第4个ViewController,如果我按下一个按钮,我需要来到第一个ViewController.

如何从NavigationController底部呈现ViewController？

Answer 1

试试这个:

CATransition *animation = [CATransition animation]; 
[animation setDuration:2]; 
[animation setType:kCATransitionPush]; 
[animation setSubtype:kCATransitionFromTop]; 
[animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]]; 
SecondView *sObj=[[SecondView alloc] initWithNibName:@"SecondView" bundle:nil];
[self.navigationController pushViewController:sObj animated:YES];
[[sObj.view layer] addAnimation:animation forKey:@"SwitchToView1"];
