ios界面跳转问题，两种方式解决

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];

[self presentModalViewController:ickImageViewController animated:YES];

//返回

[self dismissModalViewControllerAnimated:YES];
