实现的效果是这样

大概意思就是第一组没有数据就直接将改组的cell高度变成0
效果实现了，但是第二组数据创建cell就出问题了--奇葩问题

- 代码问题在这
-(CGSize)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout *)collectionViewLayout sizeForItemAtIndexPath:(NSIndexPath *)indexPath{
if (indexPath.section == 0) {
if (self.couponDataArr.count) {
return CGSizeMake(SCREEN_WIDTH, AUTO_SCALE_H(103));
}else{
return CGSizeMake(SCREEN_WIDTH, 0);
}
}else if(indexPath.section == 1){
return CGSizeMake((MainScreenWidth- 10)/2, (MainScreenWidth- 10)/2+98);
}else{
return CGSizeZero;
}
}
就这样加个.1就好了

if (indexPath.section == 0) {

return CGSizeMake(SCREEN_WIDTH, AUTO_SCALE_H(103));
}else{
return CGSizeMake(SCREEN_WIDTH, 0.1);
}
}else if(indexPath.section == 1){
return CGSizeMake((MainScreenWidth- 10)/2, (MainScreenWidth- 10)/2+98);

三张图，应该很是明了
