I'm trying to use Associated Objects on my objective-c category and I'm getting this warning. <pre class="prettyprint"><code>Implicit declaration of function 'objc_getAssociatedObject' is invalid in C99 </code></pre> Also I'm using arc if that makes a difference.

have you added <pre class="prettyprint"><code>#import <objc/runtime.h> </code></pre> at the beginning of your file?
