从plist读取时，表情符号iCons无法正确显示 [英] Emoji iCons are not displaying correctly when read from plist

问题描述

我正在尝试从plist文件中读取一些文本，并在警报框中将其显示给用户.

I am trying to read some text from a plist file and display it to the users in alert box.

当我使用此代码构建字符串时，一切正常(用户看到带有一个笑脸图标的Hello):

When I build the string using this code, everything works (users sees Hello with a smily icon):

NSString *hello = @"Hello \ue415";

但是当我从plist获取字符串时，使用此代码，使用的是"Hello \ ue415":

but when I get the string from plist, using this code, uses sees "Hello \ue415":

NString *hello =  (NSString *)[pageLiteratureDic objectForKey:litratureKey];

我必须对字符串进行不同的编码吗?任何帮助或指示将不胜感激...每个人都喜欢表情符号;)

Do I have to encode string differently? Any help or pointers will be much appreciated... everyone love emojis ;)

推荐答案

您不应该在plist文件中直接输入"\ ue415"作为文本.\ u ....是C语言中字符串和字符的语法中的转义序列.字符串本身不包含反斜杠和"u"等，它仅包含1个字符，即在代码点0xe415处的Unicode字符.如果要将其保存在plist中，则必须自己在其中手动键入该Unicode字符，并确保使用plist所需的任何编码(可能是utf-8或utf-16，不确定).或者，您可以编写一个程序从该字符串创建一个plist，然后将该plist文件中的内容复制并粘贴到您的文件中.

You shouldn't literally type "\ue415" as text into the plist file. \u.... is an escape sequence in the syntax of strings and characters in the C language. The string itself does not contain backslash and "u" and whatever, it contains just 1 character, the Unicode character at the codepoint 0xe415. If you want to save that in a plist, you have to manually type that one Unicode character in there yourself, making sure to use whatever encoding that is required of a plist (maybe utf-8 or utf-16, not sure). Alternately, you can write a program that creates a plist from that string, and then copy and paste whatever is in that plist file over to your file.
