title: Custom property's getter and setter with c++ struct array in objective-c
body: <p>I've got an c-struct array, and want to define a property.
  Here is the relative code..</p>
  
  <pre><code>struct Vertex {
      float x, y, z;
      float nx, ny, nz;
      float u, v;
  };
  
  @interface Mesh : NSObject{
      Vertex m_vertices[MaxVertices];
  }
  @property (nonatomic) Vertex m_vertices[MaxVertices];
  @end
  
  @implementation Mesh;
  @synthesize m_vertices[MaxVertices];
  @end
  </code></pre>
  
  <p>I first wrote like this with an error.
  how to set the property with c-struct array, or customlize the setter and getter?
  Any tips will be appreciated!</p>
