Trying to understand how to use xib files - objective-c

Question

I have a custom view that I'm using in a xib file. I load the view and add it to a window. It adds the view just fine as I can see the default text of the labels in the view, but when I try to change the label with a method call, it doesn't change the text.
The custom view isn't anything to fancy, just draws a rounded, transparent background.
NotificationView.h
#import <Cocoa/Cocoa.h>
#interface NotificationView : NSView
#property (weak) IBOutlet NSTextField *primaryLabel;
#property (weak) IBOutlet NSTextField *secondaryLabel;
#property (weak) IBOutlet NSTextField *identifierLabel;
#end
NotificationView.m
#implementation NotificationView
#synthesize primaryLabel;
#synthesize secondaryLabel;
#synthesize identifierLabel;
- (id) initWithFrame:(NSRect)frameRect
{
self = [super initWithFrame:frameRect];
if (self)
{
return self;
}
return nil;
}
- (void)drawRect:(NSRect)dirtyRect
{
NSColor *bgColor = [NSColor colorWithCalibratedWhite:0.0 alpha:0.6];
NSRect rect = NSMakeRect([self bounds].origin.x + 3, [self bounds].origin.y + 3, [self bounds].size.width - 6, [self bounds].size.height - 6);
NSBezierPath *path = [NSBezierPath bezierPathWithRoundedRect:rect xRadius:5.0 yRadius:5.0];
[path addClip];
NSShadow *shadow = [[NSShadow alloc] init];
[shadow setShadowColor:[NSColor redColor]];
[shadow setShadowBlurRadius:2.0f];
[shadow setShadowOffset:NSMakeSize(0.f, -1.f)];
[shadow set];
[bgColor set];
NSRectFill(rect);
[super drawRect:dirtyRect];
}
#end
In the xib I have a custom view set to the type NotificationView. I've added 3 labels to the view and connected them to the above IBOutlets. (I ctrl-click & drag from the label to the .h file to make the connection.)
I'm loading the view and adding it to a window with the following method. It looks through an array of windows, if an existing match is found it used that window, if not it creates a new window.
- (void) popupNotificationWithTag:(NSString *)tag fade:(double)msFade lineOne:(NSString *)lineOneText lineTwo:(NSString *)lineTwoText
{
NotificationWindow *notificationWindow;
NotificationWindow *tmpWindow;
NSEnumerator *enumerator;
// Walk the notification windows in the array
enumerator = [self.notificationWindows objectEnumerator];
if(enumerator)
{
while((tmpWindow = [enumerator nextObject]))
{
if([tmpWindow.tag isEqualToString:tag])
{
notificationWindow = tmpWindow;
}
}
}
// Make a new notification window
if (!notificationWindow)
{
int width = [[NSScreen mainScreen] frame].size.width;
int height = [[NSScreen mainScreen] frame].size.height;
notificationWindow = [[NotificationWindow alloc] initWithRect:NSMakeRect(width - 420, height - 130, 400, 100)];
NSNib *nib = [[NSNib alloc] initWithNibNamed:#"Notification" bundle: nil];
NSArray *objects;
[nib instantiateNibWithOwner:self topLevelObjects:&objects];
for (id obj in objects) {
if ([[obj class] isSubclassOfClass:[NSView class]])
[notificationWindow setContentView:obj];
}
[notificationWindow setTag:tag];
[self.notificationWindows addObject:notificationWindow];
}
// Display window
[notificationWindow makeKeyAndOrderFront:nil];
[notificationWindow display];
notificationWindow.fadeOut = msFade;
[notificationWindow setPrimaryText:lineOneText];
[notificationWindow setSecondaryText:lineTwoText];
[notificationWindow setIdentifierText:tag];
}
The window class is NotificationWindow.h
#import <Foundation/Foundation.h>
#interface NotificationWindow : NSWindow
#property (nonatomic, strong) NSString *tag;
#property (nonatomic) double fadeOut;
- (id)initWithRect:(NSRect)contentRect;

So I assume I'm doing something wrong connecting the labels to the IBOutlets, but I can't figure out what. I suppose I could create the view in code, but I was trying to be good and use the interface builder.
I'm in XCode 4.2.1.
