推荐答案

对不起，这太晚了……但这也许会对尚未找到答案的人有所帮助.如果您将图像放在一个数组中，您可以简单地参考图像大小并从那里调整单元格大小:

Sorry this is super late... But maybe this will help people who haven't found an answer yet. If you have your images in an array, you can simply reference the image size and make the adjustments to the cell size from there:

- (CGSize)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout sizeForItemAtIndexPath:(NSIndexPath *)indexPath
{
    UIImage *image = [imageArray objectAtIndex:indexPath.row];
//You may want to create a divider to scale the size by the way..
    return CGSizeMake(image.size.width, image.size.height); 
}

希望这会有所帮助..
