强制标签文本从左到右，同时包含一些从右到左的文本 [英] Forcing label text to left-to-right while including some right-to-left text

问题描述

我有一个字符串د.إ.，它代表货币符号，是从 NSLocale(localeIdentifier:"ar_AE").objectForKey(NSLocaleCurrencySymbol)中获得的！字符串

I have a string د.إ. that represent a currency symbol and that I get from NSLocale(localeIdentifier: "ar_AE").objectForKey(NSLocaleCurrencySymbol) as! String

在我的 UILabel 中，当我将文本设置为 theSymbol + aNumber 时(我什至无法在此处写下它，它也被颠倒了)，显示为 aNumber + theSymbol ，因为该符号最有可能由应该从右到左显示的字符串组成.

In my UILabel, when I set the text to theSymbol + aNumber (I cannot even write it down here, it gets reversed as well), it is displayed as aNumber + theSymbol as most probably the symbol is made of strings that should be displayed right-to-left.

无论符号是什么，如何强制我的标签从左到右显示?

How can I force my label to display this left-to-right, whatever the symbol is?

推荐答案

我找到了一种使其工作的方法:

I found a way to make it work:

label.text = "\u{202A}" + symbol + "\u{202C}" + "1234"

\ u {202A} 用于从左到右的嵌入，而 \ u {202C} 用于Pop-Directional-Formatting.

\u{202A} is for Left-to-Right Embedding and \u{202C} is for Pop-Directional-Formatting.
