DEInfiniteTileMarqueeView is a self-contained widget that takes an image, tiles it horizontally or vertically, and makes the tiles scroll forever. Great for futuristic UI effects (or a marquee screensaver). Both IB and programmatic friendly.
(The framerate is slow in the gif: the actual widget will render smoothly.)
First, make sure that your marquee view's width (or height, if the animation is vertical) is an integer multiple of the tileImage width(height), otherwise there will be visual looping issues. Also, the marquee view's height(width, if animation is vertical) should match the image's height(width).
Then, specify a direction (left-to-right, right-to-left, top-to-bottom, or bottom-to-top), an image to tile, and how long it takes for a tile to scroll across its width, and you're done.
-(void)viewDidLoad {
// width is 5x image width, height is the same as image height
self.marqueeView = [[DEInfiniteTileMarqueeView alloc] initWithFrame:CGRectMake(0.f,0.f,100.f,20.f)];
self.marqueeView.direction = DEInfiniteTileMarqueeViewDirectionRightToLeft;
// this will load an image where width = height = 20pt
UIImage *marqueeImage = [UIImage imageNamed:@"..."];
self.marqueeView.tileImage = marqueeImage;
self.marqueeView.tileDuration = 0.5;
}
