如何使用Xcode 4.2区分多个目标 [英] How to differentiate multiple targets with Xcode 4.2

问题描述

我已经开发了精简版的应用程序.现在，我想创建一个付费版本. 因此，我复制了目标，更改了名称(因此，用该名称更改了plist和其他内容)，现在我必须区分代码.我正在使用Xcode 4.2，并且在网络上看到必须创建预处理器标志.我的问题是Xcode 4.2中的此标志仅在项目的构建设置中，而不在目标的构建设置中.

I've developed a lite version of an app. Now I want to create a paid version. So I've duplicated the target, changed its name (so change plist and other stuff with that name) and now I have to differentiate in code. I'm using Xcode 4.2 and I see on the web that I have to create a preprocessor flag. My problem is that this flag in Xcode 4.2 is only in the project's build setting and not in the target's build setting.

我将需要能够执行以下操作:

I will need to be able to do something like this:

#ifdef paid
    ...
#else
    ...
#endif

推荐答案

使用预处理程序宏来执行此操作. 转到目标->构建设置，然后选择所有配置"(这非常重要). 接下来找到预处理器宏"字段.

Use preprocessor macros to do this. Go to Target -> Build Setting and choose "All configurations" (this is very important). Next find field "Preprocessor Macros".

在此字段中，将标记添加到ex中. PAID_VERSION.现在，您可以在代码中使用此标志:

In this field, add the flag in ex. PAID_VERSION. Now you can use this flag in code:

#ifdef PAID_VERSION
    NSLog(@"Paid version");
#else
    NSLog(@"Lite version");
#endif
