Usually the windows you display in your application will come from a NibFile inside your application’s main bundle. But this may not always be the case; sometimes it might be better to load a window from some other bundle than your own.

Loading a NibFile from a bundle is a little more difficult than from your application code. Why? *+[NSBundle loadNibNamed:] * will only look for the NibFile in your main bundle (your app). So, you’ll need to use the correct bundle to find and load your NibFile. Here’s an example:

• (void)loadMyNib { //The nib loading code expects parameters in a dictionary. We’ll make a quick one here. //Note: there are easier ways of making a dictionary. Just make sure self is the value for @”NSOwner” NSDictionary* table = [NSDictionary dictionaryWithObjectsAndKeys:self, @”NSOwner”, nil];

  //Get your bundle with [NSBundle bundleForClass:[self class]] //Pass in the name of your bundle (remember, don’t use an extension!) //Pass in our table //Get your zone (not that we pay much attention to them these days) with [self zone] [[NSBundle bundleForClass:[self class]] loadNibFile:@”myNib” externalNameTable:table withZone:[self zone]]; }
