blocks|key|2114686|text|对于这种类型的错误，我通常会看到：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2114687|+Undefined+symbols+for+architecture+armv6:

For this type of error, this is what I typically see:

<pre><code> Undefined symbols for architecture armv6:
 "_OBJC_CLASS_$_MyCustomController", referenced from:
 objc-class-ref in SomeOtherController.o
ld: symbol(s) not found for architecture armv6
</code></pre>

Almost every time I see this error it is caused by hidden/invisible characters in the import statement in <code>SomeOtherController.h</code> or <code>SomeOtherController.m</code>. So, look at both your .h and .m file, find the line that looks like this:

<pre><code>#import "MyCustomController.h"
</code></pre>

Delete this line and retype it (do not copy/paste it -- you'll just repaste the offending hidden character).

Here's how I got this problem:

I added a <code>.h</code>, <code>.m</code> and NIB from another project by dragging them onto my project navigator. Xcode didn't add them to the Build Phases properly.

My solution for this problem:

<img src="https://i.stack.imgur.com/BvuA5.png" alt="enter image description here">

<ul>
<li>Click on the Project icon</li>
<li>Go to the Target in the navigator menu</li>
<li>Click on the "Build Phases" tab</li>
<li>Add the <code>.m</code> file to "Compile Sources" (either drag it across, or use the + button)</li>
<li>Add the <code>.xib</code> or Storyboard file to "Copy bundle resources"</li>
<li>Clean and build</li>
</ul>

I had a similar issue popping-up all suddenly - more specifically, I was getting <code>Undefined symbols for architecture armv6: "_OBJC_CLASS_$_CLLocationManager", referenced from: objc-class-ref in MyCLController.o</code>

Note that I had CoreLocation.framework listed in my frameworks (in xcode' Project left nav, under the Frameworks folder); and had previously geolocation working just fine. 

I got rid of the issue by re-installing CoreLocation.framework.

If you're not sure how to do that in xcode: 
* click on your project in xcode left nav bar 
* Go in the General tab of your project settings 
* Navigate down - you'll see the list of frameworks installed under <code>Linked Frameworks and Libraries</code> 
* Click on the <code>+</code> icon to add the CoreLocation.framework

I am patching upp an application from iOS 4.2 to 4.3 using new xcode4.
With no changes made, except setting iOS to 4.3, I created entitlements and go!

Message I get is:

<pre><code>Undefined symbols for architecture armv6:"function", referenced from:

Ive tried to Clean the project, reinstalling xcode. 
I uninstalled also the xcode4 demo version.
I also tried to set to Optimized armv7.

I would be very happy for some help, I'm stuck. Really.

Thanks very much in advance!
