How do I check the TARGET_NAME of my iPhone app on XCode?
提问by onigiri
I'm trying to have 2 version of my iPhone application within the same XCode project.
The codebase it's almost the same and where I need to have different behaviours I've decided to use preprocessor's conditionals and the ${TARGET_NAME}tag.
我正在尝试在同一个 XCode 项目中拥有 2 个版本的 iPhone 应用程序。代码库几乎相同，我决定使用预处理器的条件和${TARGET_NAME}标记在哪些地方需要有不同的行为。
I've set the OTHER_CFLAGSto contain "-DTARGET_NAME=${TARGET_NAME}".
我已将 设置OTHER_CFLAGS为包含“ -DTARGET_NAME=${TARGET_NAME}”。
Then in my code I tried to do
然后在我的代码中我试图做
#if TARGET_NAME == myApp
NSLog(@"pro");
#elif TARGET_NAME == myAppLite
NSLog(@"lite");
#endif
Unfortunately I always get "lite" printed out since TARGET_NAME == myAppit's always true: since TARGET_NAMEis defined. I cannot for the life of me figure out how to evaluate this string comparison.
Any idea?
不幸的是，我总是打印出“lite”，因为TARGET_NAME == myApp它总是正确的：因为TARGET_NAME已定义。我一生都无法弄清楚如何评估这个字符串比较。任何的想法？
thanks in advance
提前致谢

You can't compare strings like that in an #ifblock. Instead, add the defines to each specific target. For instance, on the full version's target, open the Info panel and go to the build tab and add something like FULL_VERSIONto the GCC_PREPROCESSOR_DEFINITIONSbuild setting. Then, for the lite target, enter something like LITE_VERSION. In your code, you can do:
你不能在#if块中比较这样的字符串。相反，将定义添加到每个特定目标。例如，在完整版本的目标上，打开“信息”面板并转到“构建”选项卡并FULL_VERSION在GCC_PREPROCESSOR_DEFINITIONS构建设置中添加类似内容。然后，对于 lite 目标，输入类似LITE_VERSION. 在您的代码中，您可以执行以下操作：
#ifdef FULL_VERSION
NSLog(@"Full");
#else
NSLog(@"Lite");
#endif

Actually you can get the target's name to compare it, but this will not skip unnecessary code from other targets at compile time, to do this:
实际上，您可以获取目标的名称以进行比较，但这不会在编译时跳过其他目标中不必要的代码，以执行以下操作：
First go to menu Product -> Scheme -> Edit Scheme... (or CMD + <) Then in the arguments section, add inside environment variables something like:
首先转到菜单 Product -> Scheme -> Edit Scheme...（或 CMD + <）然后在参数部分，添加内部环境变量，例如：
In your code you can get the target's name as:
在您的代码中，您可以将目标名称设为：
NSString *targetName = [[NSProcessInfo processInfo] environment][@"TARGET_NAME"];
NSLog(@"target = %@", targetName); // Will print the target's name
You can compare that string now in runtime.
您现在可以在运行时比较该字符串。
But following your example: if you want that all the Pro version code to be omitted at compile time. You should do what @jason-coco says. And go to preprocessor macrosin build settings, and add $(TARGET_NAME)there:
但是按照您的示例：如果您希望在编译时省略所有 Pro 版本代码。你应该按照@jason-coco 所说的去做。并转到构建设置中的预处理器宏，并在$(TARGET_NAME)那里添加：
The code inside the #define will be compiled and executed if my target is "MLBGoldPA"
如果我的目标是“MLBGoldPA”，#define 中的代码将被编译和执行
#if defined MLBGoldPA
NSLog(@"Compiling MLBGoldPA");
#endif

to get your conditional evaluation working, you have to do something like:
要使条件评估起作用，您必须执行以下操作：
#define myApp 1
#define myAppLite 2
beforehand, like in your _Prefix.pch file.
事先，就像在你的 _Prefix.pch 文件中一样。
