viewDidLoad not being called after addSubview

[CrystalBlue]

I don't know if I'm doing something wrong or not, but I can't find the problem in my code yet.

I have two main views that I'm trying to get to work. One has been working, the other one won't show up when I call addSubview. And just to be sure, I am commenting their lines of code out to load each one individually for testing.

Here's my code...

UtilAppAppDelegate.h

#import <UIKit/UIKit.h>

@class UtilAppViewController;
@class DataSynchViewController;

@interface UtilAppAppDelegate : NSObject <UIApplicationDelegate> {
    UIWindow *window;
	
    UtilAppViewController *dwgViewController;
    DataSynchViewController *dsViewController;
}

@property (nonatomic, retain) IBOutlet UIWindow *window;

@property (nonatomic, retain) IBOutlet UtilAppViewController *dwgViewController;
@property (nonatomic, retain) IBOutlet DataSynchViewController *dsViewController;

@end

UtilAppAppDelegate.m

#import "UtilAppAppDelegate.h"

#import "UtilAppViewController.h"
#import "DataSynchViewController.h"

@implementation UtilAppAppDelegate

@synthesize window;
@synthesize dwgViewController;
@synthesize dsViewController;

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    
    
    // Override point for customization after app launch
    //[window addSubview:dwgViewController.view];
    [window addSubview:dsViewController.view];
    [window makeKeyAndVisible];

	return YES;
}


- (void)dealloc {
    [dsViewController release];
    [dwgViewController release];
    [window release];
    [super dealloc];
}


@end

UtilAppViewController.h

#import <UIKit/UIKit.h>

@interface UtilAppViewController : UIViewController {

}

@end

UtilAppViewController.m

#import "UtilAppViewController.h"

@implementation UtilAppViewController

// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
    NSLog(@"Hellos");
}

- (void)dealloc {
    [super dealloc];
}

@end

DataSynchViewController.h

#import <UIKit/UIKit.h>

@interface DataSynchViewController : UIViewController {

}

@end

DataSynchViewController.m

#import "DataSynchViewController.h"

@implementation DataSynchViewController

// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
    NSLog(@"Hellos");
}

- (void)dealloc {
    [super dealloc];
}

@end

Anyways, when I load up the UtilAppViewController (dwgViewController) I get the NSLog just fine. But when I, instead, try to load up the DataSynchViewController (dsViewController) nothing hapapens. It never gets to the viewDidLoad for that controller. What am I doing wrong here?

After hitting my head against the computer enough times, I realized that I don't like Interface Builder. I had to set a reference outlet on the dsViewController. I'm still not getting any controls to show up, but as least I got to the viewDidLoad.
