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..

前面的答案没有考虑iPhone SDK 2.0到2.1之间发生的NIB (XIB)结构的变化。用户内容现在从索引0开始，而不是1。

你可以使用2.1宏，它适用于所有2.1及以上版本(在IPHONE前面加两个下划线):

 // Cited from previous example
 NSArray* nibViews =  [[NSBundle mainBundle] loadNibNamed:@"QPickOneView" owner:self options:nil];
 int startIndex;
 #ifdef __IPHONE_2_1
 startIndex = 0;
 #else
 startIndex = 1;
 #endif
 QPickOneView* myView = [ nibViews objectAtIndex: startIndex];
 myView.question = question;

我们在大多数应用程序中都使用类似的技术。

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。

这是一个很好的问题(+1)，答案几乎是有帮助的;)抱歉，伙计们，虽然Gonso和AVeryDev都给出了很好的提示，但我花了很长时间才读完这篇文章。希望这个答案能帮助到其他人。

MyVC是持有这些东西的视图控制器。

MySubview是我们想从xib中加载的视图

In MyVC.xib, create a view of type MySubView that is the right size & shape & positioned where you want it. In MyVC.h, have IBOutlet MySubview *mySubView // ... @property (nonatomic, retain) MySubview *mySubview; In MyVC.m, @synthesize mySubView; and don't forget to release it in dealloc. In MySubview.h, have an outlet/property for UIView *view (may be unnecessary, but worked for me.) Synthesize & release it in .m In MySubview.xib set file owner type to MySubview, and link the view property to your view. Lay out all the bits & connect to the IBOutlet's as desired Back in MyVC.m, have NSArray *xibviews = [[NSBundle mainBundle] loadNibNamed: @"MySubview" owner: mySubview options: NULL]; MySubview *msView = [xibviews objectAtIndex: 0]; msView.frame = mySubview.frame; UIView *oldView = mySubview; // Too simple: [self.view insertSubview: msView aboveSubview: mySubview]; [[mySubview superview] insertSubview: msView aboveSubview: mySubview]; // allows nesting self.mySubview = msView; [oldCBView removeFromSuperview];

对我来说棘手的一点是:其他答案中的提示从xib加载了我的视图，但没有替换MyVC中的视图(呸!)——我必须自己交换。

同样，为了访问mySubview的方法，.xib文件中的view属性必须设置为mySubview。否则，它会返回一个普通的UIView。

如果有一种方法来加载mySubview直接从它自己的xib，那将摇滚，但这让我在我需要的地方。

Swift用户可设计选项:

Create a custom UIView subclass and a xib files, that we will name after our own class name: in our case MemeView. Inside the Meme View class remember to define it as designable with the @IBDesignable attribute before the class declaration Rember to set the File’s Owner in the xib with our custom UIView subclass in Indetity Inspector panel In the xib file now we can build our interface, make constraints, create outlets, actions etc. We need to implement few methods to our custom class to open the xib once initialized class XibbedView: UIView { weak var nibView: UIView! override convenience init(frame: CGRect) { let nibName = NSStringFromClass(self.dynamicType).componentsSeparatedByString(".").last! self.init(nibName: nibName) } required init?(coder aDecoder: NSCoder) { super.init(coder: aDecoder) let nibName = NSStringFromClass(self.dynamicType).componentsSeparatedByString(".").last! let nib = loadNib(nibName) nib.frame = bounds nib.translatesAutoresizingMaskIntoConstraints = false addSubview(nib) nibView = nib setUpConstraints() } init(nibName: String) { super.init(frame: CGRectZero) let nibName = NSStringFromClass(self.dynamicType).componentsSeparatedByString(".").last! let nib = loadNib(nibName) nib.frame = bounds nib.translatesAutoresizingMaskIntoConstraints = false addSubview(nib) nibView = nib setUpConstraints() } func setUpConstraints() { ["V","H"].forEach { (quote) -> () in let format = String(format:"\(quote):|[nibView]|") addConstraints(NSLayoutConstraint.constraintsWithVisualFormat(format, options: [], metrics: nil, views: ["nibView" : nibView])) } } func loadNib(name: String) -> UIView { let bundle = NSBundle(forClass: self.dynamicType) let nib = UINib(nibName: name, bundle: bundle) let view = nib.instantiateWithOwner(self, options: nil)[0] as! UIView return view } } In our custom class we can also define some inspecatable properties to have full control over them from interface builder @IBDesignable class MemeView: XibbedView { @IBInspectable var memeImage: UIImage = UIImage() { didSet { imageView.image = memeImage } } @IBInspectable var textColor: UIColor = UIColor.whiteColor() { didSet { label.textColor = textColor } } @IBInspectable var text: String = "" { didSet { label.text = text } } @IBInspectable var roundedCorners: Bool = false { didSet { if roundedCorners { layer.cornerRadius = 20.0 clipsToBounds = true } else { layer.cornerRadius = 0.0 clipsToBounds = false } } } @IBOutlet weak var label: UILabel! @IBOutlet weak var imageView: UIImageView!

}

一些例子:

如果我们需要在一个故事板或另一个xib中显示视图时添加更多信息，为此我们可以实现prepareForInterfaceBuilder()，此方法仅在接口生成器中打开文件时执行。 如果你做了我写的所有事情，但没有任何工作，这是一种通过在实现中添加断点来调试单个视图的方法。 这是视图层次结构。

希望这对您有所帮助，完整的示例可以在这里下载

我做了一个我喜欢的分类:

UIView + NibInitializer.h

#import <UIKit/UIKit.h>

@interface UIView (NibInitializer)
- (instancetype)initWithNibNamed:(NSString *)nibNameOrNil;
@end

UIView + NibInitializer.m

#import "UIView+NibInitializer.h"

@implementation UIView (NibInitializer)

- (instancetype)initWithNibNamed:(NSString *)nibNameOrNil
{
    if (!nibNameOrNil) {
        nibNameOrNil = NSStringFromClass([self class]);
    }
    NSArray *viewsInNib = [[NSBundle mainBundle] loadNibNamed:nibNameOrNil
                                                        owner:self
                                                      options:nil];
    for (id view in viewsInNib) {
        if ([view isKindOfClass:[self class]]) {
            self = view;
            break;
        }
    }
    return self;
}

@end

然后，像这样调用:

MyCustomView *myCustomView = [[MyCustomView alloc] initWithNibNamed:nil];

如果你的nib不是你的类名，请使用一个nib名。

为了在你的子类中覆盖它以获得额外的行为，它可以看起来像这样:

- (instancetype)initWithNibNamed:(NSString *)nibNameOrNil
{
    self = [super initWithNibNamed:nibNameOrNil];
    if (self) {
        self.layer.cornerRadius = CGRectGetHeight(self.bounds) / 2.0;
    }
    return self;
}
