我正在为 iPad 开发一个应用程序。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。我在 iPad 上只有默认字母字符，好像“Apple Braille”字体名称无法识别。

有什么帮助吗？谢谢你。

使用解决：

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

Apple Braille 不是 iOS 上的内置系统字体之一。请参阅此问题以了解如何在 iOS 应用程序中使用自定义字体。

还有一个问题是你是如何提供角色的？您是否在此字体中使用了常规拉丁字符“az”？也许您应该尝试使用特定于盲文的 Unicode 字符，这应该适用于标准字体。
