Question

我正在为iPad开发一款应用。出于测试目的，我需要我的应用程序在iPad屏幕上显示盲文字符。使用objective-c我将字体名称设置为“Apple Braille”：

outletText.font = [UIFont fontWithName:@"Apple Braille" size:fontSize];

但它不起作用。我的iPad上只有默认的字母字符，就像“Apple Braille”字体名称一样，无法识别。

有任何帮助吗？谢谢。

Answer 1

Apple Braille不是iOS上的内置系统字体之一。有关如何在iOS应用中使用自定义字体，请参阅this question。

我从未使用过@＆＃34; Apple Braille＆＃34;字体，我怀疑它是预装的。基于this article，iPhone上的可用字体列表如下所示：

另外一个问题是你是如何提供角色的？你使用过普通的拉丁字符＆＃34; a-z＆＃34;用这个字体？也许您应该尝试使用Unicode characters specific for Braille，这应该使用标准字体。

解决使用：

    brailleSymbol = [[NSMutableString alloc] initWithBytes:&brailleUnicode length:sizeof(brailleUnicode) encoding:NSUTF32LittleEndianStringEncoding];
