我也想做一些类似的事情，这是我发现的: (SDK 3.1.3)

我有一个视图控制器a(本身由一个导航控制器拥有)，它在一个按钮按下加载VC B:

在AViewController.m

BViewController *bController = [[BViewController alloc] initWithNibName:@"Bnib" bundle:nil];
[self.navigationController pushViewController:bController animated:YES];
[bController release];

现在VC B有它的接口从Bnib，但当一个按钮被按下，我想去一个“编辑模式”有一个独立的UI从不同的nib，但我不想要一个新的VC的编辑模式，我想新的nib与我现有的B VC相关联。

在BViewController中。M(按按钮方式)

NSArray *nibObjects = [[NSBundle mainBundle] loadNibNamed:@"EditMode" owner:self options:nil];
UIView *theEditView = [nibObjects objectAtIndex:0];
self.editView = theEditView;
[self.view addSubview:theEditView];

然后按下另一个按钮(退出编辑模式):

[editView removeFromSuperview];

我又变回了原来的Bnib

这很好，但请注意我的EditMode。nib中只有一个顶级obj，一个UIView obj。 不管这个nib中的文件所有者是设置为BViewController还是默认的NSObject，但要确保文件所有者中的视图出口没有设置为任何东西。 如果是，那么我得到一个exc_bad_access崩溃，xcode继续加载6677个堆栈帧 显示一个内部UIView方法被反复调用…看起来像一个无限循环。 (视图出口是设置在我原来的Bnib然而)

希望这能有所帮助。

对于那些需要管理多个自定义视图实例的人，也就是Outlet Collection，我合并并定制了@Gonso， @AVeryDev和@Olie的答案:

Create a custom MyView : UIView and set it as "Custom Class" of the root UIView in the desired XIB; Create all outlets you need in MyView (do it now because after point 3 the IB will propose you to connect outlets to the UIViewController and not to the custom view as we want); Set your UIViewController as "File's Owner" of the custom view XIB; In the UIViewController add a new UIViews for each instance of MyView you want, and connect them to UIViewController creating an Outlet Collection: these views will act as "wrapper" views for the custom view instances; Finally, in the viewDidLoad of your UIViewController add the following lines:

NSArray *bundleObjects; MyView *currView; NSMutableArray *myViews = [NSMutableArray arrayWithCapacity:myWrapperViews.count]; for (UIView *currWrapperView in myWrapperViews) { bundleObjects = [[NSBundle mainBundle] loadNibNamed:@"MyView" owner:self options:nil]; for (id object in bundleObjects) { if ([object isKindOfClass:[MyView class]]){ currView = (MyView *)object; break; } } [currView.myLabel setText:@"myText"]; [currView.myButton setTitle:@"myTitle" forState:UIControlStateNormal]; //... [currWrapperView addSubview:currView]; [myViews addObject:currView]; } //self.myViews = myViews; if need to access them later..

最短的版本:

RSFavoritePlaceholderView *favoritePlaceholderView = [[[NSBundle mainBundle] loadNibNamed:@"RSFavoritePlaceholderView" owner:self options:nil] firstObject];

谢谢大家。 我确实找到了做我想做的事的方法。

Create your UIView with the IBOutlets you need. Create the xib in IB, design it to you liking and link it like this: The File's Owner is of class UIViewController (No custom subclass, but the "real" one). The File Owner's view is connected to the main view and its class is declared as the one from step 1). Connect your controls with the IBOutlets. The DynamicViewController can run its logic to decide what view/xib to load. Once its made the decission, in the loadView method put something like this: NSArray* nibViews = [[NSBundle mainBundle] loadNibNamed:@"QPickOneView" owner:self options:nil]; QPickOneView* myView = [ nibViews objectAtIndex: 1]; myView.question = question;

就是这样!

主bundle的loadNibNamed方法将负责初始化视图和创建连接。

现在ViewController可以根据内存中的数据显示一个视图或另一个视图，而“父”屏幕不需要为这个逻辑而烦恼。

你也可以使用UIViewController的initWithNibName而不是loadnibname。我发现这样更简单。

UIViewController *aViewController = [[UIViewController alloc] initWithNibName:@"MySubView" bundle:nil];
[self.subview addSubview:aViewController.view];
[aViewController release];  // release the VC

现在你只需要创建MySubView。xib和MySubView.h/m。在MySubView。xib设置文件的Owner类为UIViewController，视图类为MySubView。

您可以使用父xib文件来定位子视图的位置和大小。

@AVeryDev

6)将加载的视图附加到视图控制器的视图:

[self.view addSubview:myViewFromNib];

据推测，有必要将其从视图中删除以避免内存泄漏。

澄清一下:视图控制器有几个iboutlet，其中一些连接到原始nib文件中的项(像往常一样)，一些连接到加载的nib中的项。两个nib都有相同的所有者类。加载的视图覆盖了原始视图。

提示:在加载的笔尖中设置主视图的不透明度为零，那么它将不会从原始笔尖中模糊项目。
