SLCPageFlowLayout

SLCPageFlowLayout

1、卡片

SLCPageFlowLayout *layout = [[SLCPageFlowLayout alloc] init];

2、循环卡片

SLCPageFlowLayout *layout = [[SLCPageFlowLayout alloc] init];
// 循环通过设置CollectionView的datasource和contentOffset实现

3、卡片、居中放大

SLCPageFlowLayout *layout = [[SLCPageFlowLayout alloc] init];
layout.transformBlock = ^CGAffineTransform(CGFloat apartScale) {
    CGFloat scale = fabs(cos(apartScale * M_PI/4));
    return CGAffineTransformMakeScale(1.0, scale);
};

4、卡片，居中放大，覆盖

SLCPageFlowLayout *layout = [[SLCPageFlowLayout alloc] init];
layout.transformBlock = ^CGAffineTransform(CGFloat apartScale) {
	CGFloat scale = fabs(cos(apartScale * M_PI/4));
	return CGAffineTransformMakeScale(1.2, scale);
};
