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];
