Copy link

frame.size.width += CGRectGetMaxX(glyphRect) - CGRectGetMaxX(frame)

这个是让前面的一个layer的宽度放大, 防止这个layer截断glyph？但是放大的值是
CGRectGetMaxX(glyphRect) - CGRectGetMaxX(frame),是为什么呢？
拿单词“WAY”举例，每个字母都有那个kerning，
"我们需要将前一个 textLayer 取出来调整其 Rect 的宽度至新的 glyphRect 的最右边"看到文章是这么说的，但是实际上我看到的结果是：“W”的layer的宽度是到了“Y”的最左边，而不是“A”的最右边，是需要这个效果吗？
