Question

Below image is from AppFlow welcome page animation.

Not launch image, this is just part of welcome page , part of…. not all welcome page and I can’t show the animation here, so I screen shot some frames of this animation and rearrange here.

I am sure that is not a gif or any image animation, should finished by objc code. Anyone could give me some thread or sample code will be great!

Thanks

There are plenty of ways of displaying animations in iOS. For the animation you described above, I would recommend making one PNG image per frame. Then you can display the animation in a UIImageView similar to below:

imageView.animationImages = [NSArray arrayWithObjects:[UIImage imageNamed:@"1.png"], [UIImage imageNamed:@"2.png"], nil];
imageView.animationDuration = 1;
imageView.animationRepeatCount = 0;
[imageView startAnimating];

Place the UIImageView on the welcome view controller.
