    Change the animation duration to what ever length you want.

    UIImageView *myImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"myImage.png"]];
    myImageView.center = CGPointMake(100, 100);
    myImageView.alpha = 0.0;
    [self.view addSubview:myImageView];
    [UIView animateWithDuration:5.0 animations:^{
         myImageView.alpha = 1.0;
    }];
