modalviewcontroller 推送想要关闭的视图控制器
所以我创建了一个模态视图控制器，它有一个像这样的导航栏......
PurchaseSelectVendor *selectVendor = [[PurchaseSelectVendor alloc] initWithNibName:@"PurchaseSelectVendor" bundle:nil ];
UINavigationController *modalNavController = [[UINavigationController alloc] initWithRootViewController:selectVendor];
[selectVendor release];
[self presentModalViewController:modalNavController animated:YES];
[modalNavController release];
然后模态视图将推送另一个视图控制器。 （我们将其称为视图 2）
PurchaseNewItems *newItemsController = [[PurchaseNewItems alloc] initWithNibName:@"PurchaseNewItems" bundle:nil];
[[self navigationController] pushViewController:newItemsController animated:YES];
[newItemsController release];
视图 2 有一个带有完成按钮的导航栏。当用户点击“完成”按钮时，我希望它关闭到首先呈现模式视图的视图。
我尝试的所有操作都只是将视图 2 退回到呈现它的 madalview 。
实现这一目标的正确方法是什么？
So I've created a modalviewcontroller that has a navigation bar like so...
PurchaseSelectVendor *selectVendor = [[PurchaseSelectVendor alloc] initWithNibName:@"PurchaseSelectVendor" bundle:nil ];
UINavigationController *modalNavController = [[UINavigationController alloc] initWithRootViewController:selectVendor];
[selectVendor release];
[self presentModalViewController:modalNavController animated:YES];
[modalNavController release];
The modal view will then push another view controller. (We'll call it view 2)
PurchaseNewItems *newItemsController = [[PurchaseNewItems alloc] initWithNibName:@"PurchaseNewItems" bundle:nil];
[[self navigationController] pushViewController:newItemsController animated:YES];
[newItemsController release];
view 2 has a navigation bar with a done button. When the user taps the done button I want it to dismiss to the view that presented the modal view in the first place.
Everything I try just dismisses view 2 back to the madalview that presented it.
What is the proper way to accomplish this?

在 iOS 5 中，PurchaseNewItems 控制器需要告诉其
parentViewController的presentingViewController关闭模态视图控制器。 （您不能再将模态视图的呈现者称为模态视图控制器的parentViewController。）In iOS 5, the PurchaseNewItems controller needs to tell its
parentViewController'spresentingViewControllerto dismiss the modal view controller. (You can no longer refer to the presenter of a modal view as the modal view controller'sparentViewController.)
