推荐答案

你也可以使用转义序列来让它工作:

You can also use escape sequences to get it to work:

查看您想要的字符的页面:http://en.wikipedia.org/wiki/Mac_OS_Roman

see this page for the characters you want: http://en.wikipedia.org/wiki/Mac_OS_Roman

"\x80, \xE8, \xEC, \x85, \x86" 将按顺序给出大写元音:A、E、I、O、U 带元音

"\x80, \xE8, \xEC, \x85, \x86" will give the capital vowels in order: A, E, I, O, U with umlaute

"\x8A, \x91, \x95, \x9A, \x9F" 将按顺序给出小写元音:a, e, i, o, u 带元音

"\x8A, \x91, \x95, \x9A, \x9F" will give the lowercase vowels in order: a, e, i, o, u with umlaute

MacRoman 包含您需要的字符，因此如果您更喜欢在 CoreGraphics 中工作，则无需使用 UIKit.

MacRoman includes the characters you were needing, so you don't need to use UIKit if you prefer to work in CoreGraphics.
