在集合视图单元格中更改文本NSString的大小

Question

I have text in collection cell. How can I change size of the text which is NSString? I've tried something like

cell.author.text.font = [UIFont systemFontOfSize:12.0];

But it's not allowed, it says Property 'font' not found on object of type 'NSString'

CollectionCell *cell = [collectionView dequeueReusableCellWithReuseIdentifier:identifier forIndexPath:indexPath];

cell.author.text = detailData.author;

Answer 1

I think, this:

cell.author.text.font = [UIFont systemFontOfSize:12.0];

should be, this:

cell.author.font = [UIFont systemFontOfSize:12.0];

Answer 2

由于NSString没有字体信息（仅body = text），因此您必须在显示该字体的对象（作者）中指定字体。

cell.author.font = [UIFont systemFontOfSize:12.0];

Answer 3

cell.author.text.font = [UIFont systemFontOfSize:12.0];

用以下代码替换

cell.author.font = [UIFont systemFontOfSize:12.0];
