I usually build a form or control for editing the server address. The button for the form would only be available in debug builds (make it ugly and red so you don't ship it :-) ) then have it hidden in release builds.

Since it's already a URL, you could use the hostname instead of the IP, and it'll be resolved with Bonjour. For example, the laptop I'm using to write this is called Jura, which means it has a Bonjour hostname of <code>jura.local</code>.

You can find out the Bonjour DNS name of your computer by heading to the Sharing preferences pane. Under computer name, there's a sentence that starts, "Computers on your local network..." and ends with the name you want to use.

Then you can change the above code to:

<pre><code>#define API_BASE @"http://my-macbook-pro.local:3000/api"
</code></pre>

because the same mechanism will resolve the URL in the simulator and on the device.

blocks|key|1733259|text|好的，所以它需要与多个开发环境一起工作，这意味着Bonjour不会削减它。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1733260|我不太熟悉XCode构建环境。您能以某种方式设置由shell计算的环境变量吗？如果您可以以某种方式得到以下评估：|1733261|DEV_IP_ADDRESS=$(/sbin/ifconfig+%7Cawk+'/inet+127.0.0.1/+{+next+}+/inet+/+{+print+$2;+exit+}')|code-block|syntax|javascript|1733262|然后作为预处理器define传入|offset|length|style|CODE|1733263|gcc+<...>+-DDEV_IP_ADDRESS="${DEV_IP_ADDRESS}"|1733264|在守则中：|1733265|#define+API_BASE+"http://"+DEV_IP_ADDRESS+":3000/api"|1733266|(我有点生疏，但我隐约记得，预处理程序连接着连续的字符串，对吗？)|1733267|如果你能加入他们的话，那就可以了。-)|1733268|或者你可以和糖果结合在一起，让神秘的黑客更能忍受。$HOSTNAME可能已经在您的环境中定义了，所以如果您可以将其作为预处理器#define进行排序。|1733269|entityMap^0|0|0|0|8|6|0|0|0|0|0|0|P|9|1R|7|0^^$0|@$1|2|3|4|5|6|7|12|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|13|8|@]|9|@]|A|$]]|$1|D|3|E|5|F|7|14|8|@]|9|@]|A|$G|H]]|$1|I|3|J|5|6|7|15|8|@$K|16|L|17|M|N]]|9|@]|A|$]]|$1|O|3|P|5|F|7|18|8|@]|9|@]|A|$G|H]]|$1|Q|3|R|5|6|7|19|8|@]|9|@]|A|$]]|$1|S|3|T|5|F|7|1A|8|@]|9|@]|A|$G|H]]|$1|U|3|V|5|6|7|1B|8|@]|9|@]|A|$]]|$1|W|3|X|5|6|7|1C|8|@]|9|@]|A|$]]|$1|Y|3|Z|5|6|7|1D|8|@$K|1E|L|1F|M|N]|$K|1G|L|1H|M|N]]|9|@]|A|$]]|$1|10|3|-4|5|6|7|1I|8|@]|9|@]|A|$]]]|11|$]]

OK, so it needs to work with multiple development environments, which means Bonjour's not going to cut it.

I'm not terribly familiar with the XCode build environment. Can you set environment variables that are evaluated by a shell in some way? If you can somehow get the following evaluated:

<pre><code>DEV_IP_ADDRESS=$(/sbin/ifconfig |awk '/inet 127.0.0.1/ { next } /inet / { print $2; exit }')
</code></pre>

then passed in as a preprocessor <code>define</code>:

<pre><code>gcc &lt;...&gt; -DDEV_IP_ADDRESS="${DEV_IP_ADDRESS}"
</code></pre>

and, in the code:

<pre><code>#define API_BASE "http://" DEV_IP_ADDRESS ":3000/api"
</code></pre>

(I'm rusty, but I dimly recall that the preprocessor concats consecutive strings, right?)

If you can join 'em up, that should do the trick. :-)

Or you can combine with bonjour to make the arcane hackery a little more bearable. Chances are <code>$HOSTNAME</code> is already defined in your environment, so if you can get that in as a preprocessor <code>#define</code> you're sorted.

I'm working on some iPhone apps that communicate with an HTTP-based API server (which happens to be Rails, but that's irrelevant here), and oftentimes I've been bitten by the IP (un)reachability from the iPhone device to my MacBook Pro - the iPhone device must hit the URLs on the MBP.

Right now, I have something like this in Config.h:

<pre><code>#if (TARGET_IPHONE_SIMULATOR)
// for iPhone Simulator
#define API_BASE @"http://127.0.0.1:3000/api"
#else
// for iPhone Device
#define API_BASE @"http://10.0.0.1:3000/api"
#endif
</code></pre>

It works fine, as long as: 1. you work by yourself, 2. or you have full control over the DHCP server, 3. or you can work only with the iPhone simulator and use the loopback address (that is, without push notification or in-app purchase).

But I work remotely with other people, often from cafes or libraries, so it bothers me a lot - now I have to manually find my MBP's assigned IP address, rewrite the above constant API_BASE from "10.0.0.1" to the new address, and not forget to revert to the original before committing to git or svn.

Is there any ways to programatically get the IP address of the development machine from inside Xcode and send it to the iPhone device on a per-build basis?

UPDATE

Using Bonjour is not enough because every machine in the team has a different name.
