ios - IOS 中的正字连字词

Question

有正字断字的方法吗？

像这样:

NSStiring *string = @"In June 2010 at the World Wide Developers Conference, Apple announced version 4 of Xcode during the Developer Tools State of the Union address.";
UILabel *label = [[UILabel alloc] init];
label.text = string;

如果框架 UILabel 变窄，则获取下一个:

In June 2010 at
the World Wide
Developers Con-
ference, Apple
announced ver-
sion 4 of Xcode
during the Devel-
oper Tools State
of the Union ad-
dress.

Answer 1

使用带有 hyphenationFactor 为 1 的 NSParagraphStyle 的 NSAttributedString。
