title: Importing Custom Class .h file into AppDelegate.h with relative route doesn't work
body: <p>In my Cocoa Application I have created a Custom View Class (subclass of NSView), named "DragAndDropView". Its .h and .m files are placed in the same folder than the AppDelegate.h.</p>
  
  <p>Into the AppDelegate.h, I need to declare an outlet of my DragAndDropView. It looks like this:</p>
  
  <pre><code>#import &lt;Cocoa/Cocoa.h&gt;
  #import &lt;DragAndDropView.h&gt;
  
  @interface AppDelegate : NSObject &lt;NSApplicationDelegate&gt; {
  @private
      NSWindow        *window;
  
      DragAndDropView *dragAndDropView;
  
      // Files
      NSFileManager   *fileMgr;
  }
  
  // Outlets
  @property (assign) IBOutlet NSWindow *window;
  @property (assign) IBOutlet DragAndDropView *dragAndDropView;
  
  @end
  </code></pre>
  
  <p>With the import of my class (#import ), I become the following error:</p>
  
  <pre><code>'DragAndDropView.h' file not found
  </code></pre>
  
  <p>Anyone knows how can I fix it?</p>
