如何获得普通的“地球"Unicode字符 [英] How to obtain plain 'globe' Unicode character

问题描述

如果您在 NSString 中包含 Unicode 字符，它们中的很多将采用该文本的颜色集 - 它们只是该字体的常规字形，因此它们像任何其他字符一样显示特点.但是有一些 Unicode 字符是彩色的，例如 ) 进入您的应用.

或者，您可以使用您想要的图标制作位图图像并

If you include Unicode characters in an NSString, a lot of them will take on the color set for that text - they're just regular glyphs for that font so they're displayed like any other character. But there are some Unicode characters that are colored, for example GLOBE WITH MERIDIANS which is a blue gradient with shadows. But I have seen this same glyph elsewhere that's a simple black outline without a shadow, for example in the iOS keyboard. I would like to use that glyph, but without the adornments, and without having to create and use an image. I wondered if a different font would render it in a different format, and while iOSFonts.com does show different styles (bolder, italics), they're all blue. Is it possible to get the simple plain version?

Surely it is possible, because that appears to be exactly what Apple has implemented with a Tip. Notice the globe is the exact same color as the text and it's included in the string along with all the other characters. Surely that's not a UIImage?

EDIT: The solution provided in the linked question doesn't work for this character, as the variant character appears to be the exact same as the original - blue with shadows.

Unfortunately, iOS doesn't have a monochrome globe symbol you can use; the only built-in font that includes U+1F310 GLOBE WITH MERIDIANS is Apple Color Emoji.

If you really want a font that renders this character as a simple black outline, you could package a copy of Symbola (downloadable here) into your app.

Alternatively, you could make a bitmap image with the icon you want and use NSTextAttachment to put it into an attributed string. Apple is likely doing something along these lines, as many of their Tips include symbols that are definitely not Unicode characters:
