How do I configure full URLs in xcconfig files
提问by atreat
I have an xcconfig file which contains a configuration for which server my app should hit. In debug mode, this will be a different server than for release builds.
我有一个 xcconfig 文件，其中包含我的应用程序应该访问的服务器的配置。在调试模式下，这将是与发布版本不同的服务器。
The problem I have is that a URL of the form http://www.stackoverflow.comis treated as a comment after the double slash. So the string I get in code is 'http:'
我遇到的问题是形式为http://www.stackoverflow.com的 URL被视为双斜杠后的注释。所以我在代码中得到的字符串是 'http:'
I have read that I can put a -traditional build flag on Info.plist, I was wondering if someone else has had a similar issue and has solved it?
我已经读到我可以在 Info.plist 上放置一个 -traditional build 标志，我想知道是否有人遇到过类似的问题并解决了它？
Thanks.
谢谢。

from the Xcode-users mailing list: In the xcconfigfile, save the URL without the http scheme:
来自 Xcode-users 邮件列表：在xcconfigfile 中，保存不带 http 方案的 URL：
MYURL = stackoverflow.com
In the Info.plist, set the property value to
在Info.plist 中，将属性值设置为

Just declare
只需声明
SIMPLE_SLASH=/
Then your URL becomes
然后你的网址变成
http:$(SIMPLE_SLASH)/www.stackoverflow.com

SLASH=/
API_URL=http:$(SLASH)/endpoint.com

You shouldn't use a xcconfig file for this setting.
您不应为此设置使用 xcconfig 文件。
A xcconfig file is not a "normal" header or module file which is the input of the preprocessor and eventually the input for the compiler. It's nowhere specified how the xcconfig file parser treats character encoding, whether it recognizes escape sequences, whether it expands macros, and how character literals are defined and much more.
xcconfig 文件不是“正常”的头文件或模块文件，它是预处理器的输入并最终是编译器的输入。没有指定 xcconfig 文件解析器如何处理字符编码、是否识别转义序列、是否扩展宏以及如何定义字符文字等等。
It's far better in this case, to have a "config.h" header file and use a conditional based on a preprocessor definition:
在这种情况下，使用“config.h”头文件并使用基于预处理器定义的条件要好得多：
#if defined (DEBUG)
NSURL* url = ...
#else
NSURL* url = ...
#endif
Here, DEBUGis defined for Debug configuration by default. You may #define any other definition in the build settings under "Preprocessor Macros".
此处，DEBUG默认为 Debug 配置定义。您可以在“预处理器宏”下的构建设置中#define 任何其他定义。

You can use backslashes to escape:
您可以使用反斜杠来转义：
URL = "http:\/\/mydomain.com"
URL = "http:\/\/mydomain.com"

Don't forget to Clean your project before re-build.
不要忘记在重新构建之前清理您的项目。
