iOS7 custom loading screen. PNG sequence, GIF, or animated UIimages

In our iOS app, we want a loading image which is just our logo, animated. I'm wondering what the best practice is to do this? Would it be to use a series of .png images, or one long .png image. I can also thing of using a .gif but the colour quality is not the greatest.

It may also be possible, since the animation is just resizing of certain elements, to do the animation programatically using several UIimages and resizing them, though it may not be as smooth.

UIImage* img1 = [UIImage imageNamed:@"image_1.png"];
UIImage* img2 = [UIImage imageNamed:@"image_2.png"];
UIImage* img3 = [UIImage imageNamed:@"image_3.png"];
UIImage* img4 = [UIImage imageNamed:@"image_4.png"];
UIImage* img5 = [UIImage imageNamed:@"image_5.png"];

NSArray *images = [NSArray arrayWithObjects:img1,img2,img3,img4,img5,nil];

UIImageView* imageView = [[UIImageView alloc] 
         initWithFrame:CGRectMake((self.view.frame.size.width-80)/2, 50, 80.0, 80.0)];

[imageView setAnimationImages:images];
[imageView setAnimationRepeatCount:100];
[imageView setAnimationDuration:3.0];
[imageView startAnimating];
imageView.tag = 100;
[self.view addSubview:imageView];
