blocks|key|3372720|text|在AppDelegate.m上，您必须更新jsCodeLocation并用机器ip地址替换localhost。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|3372721|或者将编译后的源代码打包到应用程序中，在AppDelegate.m上也可以将其注释为选项2。下载编译后的代码，并将其添加到Xcode项目中。|3372722|entityMap^0|L|E|19|9|0|K|D|0^^$0|@$1|2|3|4|5|6|7|J|8|@$9|K|A|L|B|C]|$9|M|A|N|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|O|8|@$9|P|A|Q|B|C]]|D|@]|E|$]]|$1|H|3|-4|5|6|7|R|8|@]|D|@]|E|$]]]|I|$]]

On your AppDelegate.m you have to update the <code>jsCodeLocation</code> and replace <code>localhost</code> with your machine ip address.

Either that or bundle the compiled source into your application, which is commented as option 2 on <code>AppDelegate.m</code> as well. You download the compiled code, and add it to your Xcode project.

blocks|key|148459|text|在我的例子中，我刚刚安装了一个非常旧的node.js版本(版本0.8.6)。在将node.js更新到0.12.2版本之后，react-native+init+AwesomeProject创建的默认项目运行良好。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|148460|entityMap^0|1P|W|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|K|8|@]|D|@]|E|$]]]|G|$]]

In my case, I just had a very old version of node.js installed (version 0.8.6). After updating node.js to version 0.12.2, the default project that <code>react-native init AwesomeProject</code> created worked perfectly.

blocks|key|3372770|text|另一个可能导致完全相同错误的潜在问题是iOS9+9中的(ATS)+--这发生在我身上，尽管其他的设置都是正确的。参见我在https://stackoverflow.com/a/34880394/2397068的描述和解决方案。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|3372771|entityMap|0|LINK|mutability|MUTABLE|url|https://stackoverflow.com/a/34880394/2397068^0|1O|18|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

Another potential issue which can cause the exact same error is App Transport Security (ATS) in iOS9--this happened to me, even though everything else was set up correctly.

I have prepared a small instruction which will help to solve this problem.

When your application cannot connect to the server, you will see the message like this:

<a href="https://i.stack.imgur.com/yilNV.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/yilNV.png" alt="enter image description here"></a>

Open a file AppDelegate.m in your Xcode project and look for

<code>jsCodeLocation = [NSURL URLWithString:@"http://localhost:8081/index.ios.bundle?platform=ios&amp;dev=true"];</code>

You have to replace this address with your local address.

<a href="https://i.stack.imgur.com/bOetv.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/bOetv.png" alt="enter image description here"></a>

To look up your local IP address in Mac OS X open Terminal application (located in /Applications/Utilities) and type <code>ipconfig getifaddr en1</code> for wireless, or <code>ipconfig getifaddr en0</code> for ethernet.

<a href="https://i.stack.imgur.com/j5iAN.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/j5iAN.png" alt="enter image description here"></a> 

You can check It in browser. And you will see React Native Debugger page 

<a href="https://i.stack.imgur.com/5jKGB.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/5jKGB.png" alt="enter image description here"></a>

Just replace <code>localhost</code> in AppDelegate.m with your IP address. <code>localhost</code> to <code>192.168.1.100</code> in my case.

<a href="https://i.stack.imgur.com/ex45h.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/ex45h.png" alt="enter image description here"></a>

Run your application in Xcode again.

I'm using React-Native, when I run the AwesomeProject with Xcode and iPhone simulator everything works well, but when I connected my iPad and built the project on my iPad I receive an error on the iPad when the app starts:

<blockquote>
 "Could not connect to development server. Ensure node server is
 running. The operation couldn't be completed (NSURLErrorDomain error
 -1004)".
</blockquote>

I also ensured that the node package is running. I even restarted Xcode and started it all over with running npm start.

Could you please assist?
