title: How do I get a view in Interface Builder to load a custom view in another nib?
body: <p>I am making a custom widget that I would like to use in multiple nibs.  So I make a new view nib Screen3, add some buttons, and now want my UIAwesomeSauce widget.  </p>
  
  <p>If I just add a view and then change the Class Identity, it doesn't get the subelements from the UIAwesomeSauce nib.  Same thing if I go to the Library and switch to Classes.  It seems only a UIViewController has the field for "Load from nib", which would be beautiful.</p>
  
  <p>I know I can load the UIAwesomeSauce nib from code, get the top level objects, and place it by hand.  But the point of IB is so you don't have to place things in code.  Even better would be if I could get UIAwesomeSauce to show up in the Library list itself.</p>

  <p>Anyway, dood, that is great.  I can make my own widget classes now for goofy Awesome stuff.  Make the FileOwner of your UI nib your class, and in it just have a normal UIView with all your stuff.  (The single view in the widget's nib can't be the class itself, or you get recursive in initWithCoder.)  Then in the nib you want to use it, make a vanilla UIView and change its class.  You won't be able to actually see the widget inside that square, but deal.</p>
  
  <p>Self is now a blank view, and tMyActualSelf is the single view that you did the work in in the other nib.  Yay!  </p>
  
  <pre><code>- (id)initWithCoder:(NSCoder*)coder 
  {
      if ((self = [super initWithCoder:coder])) 
      {
          UIView *tMyActualSelf = nil;
          // Initialization code
          NSArray *tNibItems = [[NSBundle mainBundle] loadNibNamed:@"UIAwesomeSauce" owner:self options:nil];
          for (id object in tNibItems) 
          {
              if ([object isKindOfClass:[UIView class]])
                  tMyActualSelf = (UIView *)[object retain];
          }   
          if( tMyActualSelf ) 
          {
              tMyActualSelf.frame = CGRectMake(0, 0, self.frame.size.width, self.frame.size.height);
              [self addSubview:tMyActualSelf];
          }
      }
      return self;
  }
