UIImageView Animation Not Working

Just started Objective-C - trying to make 4 images fadein/fadeout continuously.

The code below is not working. I know the button is working because the text of my label changes, however no pictures animate. No errors either ...

h.

#import <UIKit/UIKit.h>

@interface ViewController : UIViewController
{

    IBOutlet UIImageView *viewer;

}

@property (nonatomic, retain) UIImageView *viewer;

@property (nonatomic,retain) IBOutlet UILabel *label1;

@end

m.

-(IBAction)startImageViewAnimation
{

label1.text = @"CHECK?";

NSArray *animationImages = [NSArray arrayWithObjects:
                            [UIImage imageNamed:@"backgrounds_app1-01.png"],
                            [UIImage imageNamed:@"backgrounds_app2-02.png"],
                            [UIImage imageNamed:@"backgrounds_app3-03.png"],
                            [UIImage imageNamed:@"backgrounds_app4-04.png"],
                            nil];

viewer = [[UIImageView alloc] initWithFrame:self.view.frame];
viewer.animationImages = animationImages ;
viewer.animationRepeatCount = 2;
viewer.animationDuration= 4.0;
[viewer startAnimating];

[NSTimer scheduledTimerWithTimeInterval:4.0 target:self
                               selector:@selector(animationDone:)
                               userInfo:nil repeats:NO];


}

-(void)animationDone:(NSTimer*)inTimer
{
[inTimer invalidate];
inTimer = nil;
NSLog(@"animationDone ");
}

After initialising the image view, you'll have to add it as a subview:

viewer = [[UIImageView alloc] initWithFrame:self.view.bounds];
[self.view addSubview:viewer];
