ios ViewController 页面跳转

 

从一个Controller跳转到另一个Controller时，一般有以下2种： 
1、利用UINavigationController，调用pushViewController，进行跳转；这种采用压栈和出栈的方式，进行Controller的管理。调用popViewControllerAnimated方法可以返回。 

   PickImageViewController *ickImageViewController =[[PickImageViewController alloc] init]; 
   [self.navigationController pushViewController:ickImageViewController animated:true]; 
   [ickImageViewController release]; 


2、利用UIViewController自身的presentModalViewController，进行跳转；调用dismissModalViewControllerAnimated方法可以返回。 
   PickImageViewController *ickImageViewController =[[PickImageViewController alloc] init]; 
    [selfpresentModalViewController:ickImageViewControlleranimated:YES]; 
//返回 
[self dismissModalViewControllerAnimated:YES];
