从几个不同的 UIViewControllers 的 NIB 文件加载视图
我已经使用此 site
[[NSBundle mainBundle] loadNibNamed:@"YourNibName" owner:self options:nil];
问题是，因为我们必须设置文件所有者，所以这个 nib 文件会“附加”到这个视图控制器。这个视图是 UITableViewCell 的子类，我想从几个不同的 vc 加载这个 nib 文件。 感谢您的帮助。
I have been loading view from Nib files successfully using the approach found on this site
[[NSBundle mainBundle] loadNibNamed:@"YourNibName" owner:self options:nil];
The problem is that, because we have to set the File Owner, this nib file becomes "attached" to this view controller. This view is subclass of UITableViewCell and I wanted to load this nib file from several different vc's.
Thanks for your help.

笔尖只是一个模板，您可以一遍又一遍地加载它。
如果使用 iOS4，您可能需要查看 UINib，它提高了重复笔尖加载的性能。
A nib is just a template, you can load it over and over again.
If using iOS4, you might want do look at UINib which gives improved performance for repeated nib loading.
我将提供两个选项：
@property（非原子，保留）IBOutlet id mainObject;和一个名为loadNibNamed:bundle:的方法创建一个 NibLoader 类。然后，执行MyView * v = [[NibLoader loadNibNamed:"MyView" bundle:nil] mainObject];。 （GCC 4.0 属性访问错误意味着 [...].mainObject 将调用 [...] 两次；已在 4.2 中修复。）@property 的，并将文件的所有者类更改为@protocol MyNibOwner（非原子，保留）IBOutlet MyView * myView;id或NSObject。I'll present two options:
@property (nonatomic, retain) IBOutlet id mainObject;and a method calledloadNibNamed:bundle:). Then, doMyView * v = [[NibLoader loadNibNamed:"MyView" bundle:nil] mainObject];. (A GCC 4.0 property access bug meant that [...].mainObject would call [...] twice; it's been fixed in 4.2.)@protocol MyNibOwnerwhich has@property (nonatomic, retain) IBOutlet MyView * myView;, and change the file's owner class toid<MyNibLoader>orNSObject<MyNibLoader>.迂腐地说，笔尖可能应该有一个控制器。我可能会做的是创建一个新的 UIViewController 子类来控制您的笔尖中的内容，然后每当您需要笔尖中的内容时，创建这些视图控制器之一并询问 它用于内容，而不是直接加载笔尖。
Pedantically, a nib should probably have a single controller. What I would probably do is create a new
UIViewControllersubclass that controls the stuff in this nib of yours, and then whenever you want the stuff in the nib, create one of these view controllers and ask it for the stuff, instead of loading the nib directly.
