ios - IOS中的正交连字词

Question

有没有正字法连字的方法？

像这样的东西：

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 会变窄，请获取下一个：
