How to enter unicode characters in a UILabel in Interface Builder?

iphoneiosunicodeutf-8interface-builder

提问by ragnarius

I would like to display a unicode character (the speaker symbol U+1F50A) in label. Is it possible to enter this symbol in Interface Builder?

我想在标签中显示一个 unicode 字符(扬声器符号 U+1F50A)。是否可以在 Interface Builder 中输入此符号?

Yes, you can click "Edit" > "Special Characters…" — there you can find all unicode characters (including the emoji) and copy/paste them where you set the label text in Interface Builder.

是的,您可以单击“编辑”>“特殊字符...”——在那里您可以找到所有 unicode 字符(包括表情符号)并将它们复制/粘贴到您在 Interface Builder 中设置标签文本的位置。

EDIT: In Xcode 6 it's "Edit" > "Emoji & Characters"

编辑:在 Xcode 6 中,它是“编辑”>“表情符号和字符”

Xcode 7+: "Edit" > "Emoji & Symbols"

Xcode 7+:“编辑”>“表情符号和符号”

For those who tried doing it programmatically, but failed, just use this:

对于那些尝试以编程方式执行但失败的人,只需使用以下命令:

label.text = @"\U0001F50A";

回答by Phillip

Do it programmatically.

以编程方式执行此操作。

Declare an IBOutlet for the Label, with the means of NSString type:

为 Label 声明一个 IBOutlet,方式为 NSString 类型:

// UTF-8 Hexadecimal Encoding
NSString *myString = [NSString stringWithUTF8String:"0xF09F948A"];

myLabel.text = myString;

Also, take a look at thisquestion.

另外,看看这个问题。

In Xcode 8/Swift 3 the easiest is to use the unicode escape:

在 Xcode 8/Swift 3 中,最简单的方法是使用 unicode 转义:

let a = "\u{1F50A}"

It's fun why few people knew this. You can enter Unicode-symbols directly by holding "Option" and entering hex digit. All you need: (Sierra example) goto "Preference -> Keyboards -> Input Sources" and search for "Unicode Hex". It should appears under "Others" section. Next add it and then you be able enter Unicode-char anywhere just selecting this input source.

有趣的是为什么很少有人知道这一点。您可以通过按住“Option”并输入十六进制数字来直接输入 Unicode 符号。您只需要:(Sierra 示例)转到“首选项 -> 键盘 -> 输入源”并搜索“Unicode Hex”。它应该出现在“其他”部分下。接下来添加它,然后你就可以在任何地方输入 Unicode-char 只需选择这个输入源。

For example: ? = (Alt+2713), - (20ac), etc. Most interesting section from 2100 to 2800. Full list you can found here - Unicode table

例如: ?= (Alt+2713)、- (20ac) 等。从 2100 年到 2800 年最有趣的部分。您可以在此处找到完整列表 - Unicode 表

P.S.: This method sutable only for four-digit Unicodes

PS:此方法仅适用于四位 Unicodes
