NSString.sizeWithAttributes支持的属性键列表？

Question

iOS 7用于NSString::sizeWithAttributes计算NSString给定NSDictionary属性的边界框的大小.但是,我找不到列出可用于其中的所有枚举键的资源NSDictionary.

在的NSString UIKit的添置参考说,

这些属性可以应用于NSAttributedString对象

但是没有列出它们,它们也没有在NSAttributedString文档中列出.

另外:可用的属性键,这是调整多线标签的最基本的？似乎字体大小和换行模式是最重要的,但没有可用选项的列表,很难说...

Answer 1

我搜索了20分钟,然后在SO上发布后立即找到答案.叹.

为了将来参考,可用属性列在NSAttributedString - Foundation Reference的底部,在Character Attributes部分中.
