我将屏幕分成小块,然后设置每个块的动画以执行转换:

    for (int x=0; x<number_of_x_splits; x++) {

    for (int y=0; y<number_of_y_splits; y++) {

        CGSize splitSize = CGSizeMake(screenBounds.width / number_of_x_splits, screenBounds.height / number_of_y_splits);

        CATransformLayer *transformLayer = [CATransformLayer layer];
        [transformLayer setFrame:CGRectMake(splitSize.width * x, splitSize.height * y, splitSize.width, splitSize.height)];
        [transformLayer setPosition:CGPointMake((splitSize.width * x) + splitSize.width / 2, (splitSize.height * y) + splitSize.height / 2)];

        ... adding some sublayers to transformLayer...

        CABasicAnimation *rotate = [CABasicAnimation animationWithKeyPath:@"transform.rotation.y"];
        [rotate setDuration:5.0];
        [rotate setFromValue:[NSNumber numberWithFloat:0]];
        [rotate setToValue:[NSNumber numberWithFloat:M_PI]];
        [rotate setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut]];
        [rotate setTimeOffset:(1 / (number_of_x_splits + number_of_y_splits)) * …
