好吧，抱歉，简而言之：在也从 nib 创建的多个视图控制器中重用从 nib 创建的视图的最佳/最简单/推荐方法是什么？

使用 NSBundle 的 - (NSArray *)loadNibNamed:(NSString *)name Owner:(id)owner options:(NSDictionary *)options 方法加载您的笔尖。

创建一个 nib 文件并将文件的所有者设置为您的视图控制器之一。只要所有相关属性都存在于两者中，哪一个并不重要。
设置笔尖，链接您的视图/按钮/等。文件的所有者属性。

在您的视图控制器中执行以下操作

@interface MyViewController : UIViewController {
}

@property (retain, nonatomic) IBOutlet UIView *myView;
// Add whatever other outlets you need for your nib.

@end

@implementation MyViewController

@synthesize myView;

- (void)viewDidLoad {
    [super viewDidLoad];

    // You set up your other views/ivars/etc. here

    [[NSBundle mainBundle] loadNibNamed:@"MyCustomView" owner:self options:nil];
    // Assuming that your bundle contains a single top-level object that is linked to the
    //  'myView' property in your view controller, everything should be properly retained
}

@end

Use the - (NSArray *)loadNibNamed:(NSString *)name owner:(id)owner options:(NSDictionary *)options method of NSBundle to load your nib.

Create a nib file and set the File's owner to one of your view controllers. It shouldn't matter which one as long as all the relevant properties are present in both.
Set up the nib, linking your views/buttons/etc. to the file's owner properties.

In your view controllers do the following

@interface MyViewController : UIViewController {
}

@property (retain, nonatomic) IBOutlet UIView *myView;
// Add whatever other outlets you need for your nib.

@end

@implementation MyViewController

@synthesize myView;

- (void)viewDidLoad {
    [super viewDidLoad];

    // You set up your other views/ivars/etc. here

    [[NSBundle mainBundle] loadNibNamed:@"MyCustomView" owner:self options:nil];
    // Assuming that your bundle contains a single top-level object that is linked to the
    //  'myView' property in your view controller, everything should be properly retained
}

@end
