1. In Interface Builder, create a new xib with the View template.
   • Click on the view in the list of objects in the xib (you should also see "File s Owner and "First Responder").
   • Push Cmd-4 to open the Identity pane of the inspector.
   • Type your class s name into the "Class Name" field and push return.

您应该能够拖动按钮来收起它们。要从代码中访问符尖方式，请使用- [NSBundle loadNibNamed:owner:options:] 。您的视图应该是返回的数组中的第一个对象。

在我的情况下，我不希望我的视图控制器了解我的视图.xib的IBOutlets。我想让我的视图子类拥有IBOutlets。不幸的是，UIView没有一个initWithNibName：方法，所以我只创建了自己的类别。

这是我做的：

• In IB, click on your main UIView, and in the Identity Inspector, set the class to your subclass
• In IB, click on File s Owner, and in the Identity Inspector, set the class to your subclass
• Use your new category method initWithNibName: to instantiate your view.

这是我创建的分类：

- (instancetype)initWithNibName:(NSString *)nibName
{
    NSArray *arrayOfViews = [[NSBundle mainBundle] loadNibNamed:nibName owner:self options:nil];
    if (arrayOfViews.count < 1) {
        return nil;
    }

    self = arrayOfViews[0];

    return self;
}

受到此帖子的启发。

Note though, that so far the frame will adjust automatically, so unlike the code in the post, I haven t yet had to explicitly set the frame. Also, unlike the post s code, I needed to set owner:self so the IBOutlets would be wired up correctly.
