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=[[PickImageViewControlleralloc]init];

[self.navigationControllerpushViewController:ickImageViewControlleranimated:true];

[ickImageViewControllerrelease];

2、利用UIViewController自身的presentModalViewController，进行跳转；调用dismissModalViewControllerAnimated方法可以返回。

PickImageViewController*ickImageViewController=[[PickImageViewControlleralloc]init];

[selfpresentModalViewController:ickImageViewControlleranimated:YES];

//返回

[selfdismissModalViewControllerAnimated:YES];
