objective-c - iOS 上的核心文本段落空间太大

Question

我使用 CoreText 来渲染文本如下:

Another very common typesetting operation is drawing a single line of text to use as a label for a user-interface element.
In Core Text this requires only two lines of code, one to create the line object with an attributed string and another to draw the line into a graphic context.
but it shows how to create an attributes dictionary and use it to create.

显然有 3 个段落。我使用默认的 CTParagraphStyleSetting 以便 ParagraphSpacing 和 ParagraphSpacingBefore 默认设置为 0。

但渲染结果显示空间太大

有减少段落空间的想法吗？
