UIVideoAtPathIsCompatibleWithSavedPhotosAlbum generates error implicit declaration of function, why?
<p>In my project I am trying to save video to the iPhone after being taken by the camera.</p>

<p>When I call the method:</p>

<p>UIVideoAtPathIsCompatibleWithSavedPhotosAlbum(path)</p>

<p>It reports the error:</p>

<p>Implicit declaration of function 'UIVideoAtPathIsCompatibleWithSavedPhotosAlbum'</p>

<p>I've imported MobileCoreServices/UTCoreTypes.h</p>

<p>I was previously using this same code for saving camera pictures, and it worked fine.</p>

<p>In another class, in the same project, I am able to reference the UIKit method:</p>

<p>UIImagePNGRepresentation()</p>

<p>without any problems</p>

<p>So why does it give me this error?</p>
