body: <p>I cannot link the ImageView component in main.storyboard to the imageView property in ViewController.m</p>
  
  <p>below are my ViewController.h file </p>
  
  <p>ViewController.h</p>
  
  <pre><code>#import &lt;UIKit/UIKit.h&gt;
  //#import "opencv2/videoio/cap_ios.h"
  
  @interface ViewController : UIViewController{
      cv::CascadeClassifier faceDetector;
  }
  
  @property (nonatomic, weak) IBOutlet UIImageView* imageView;
  @end
  </code></pre>
  
  <p>in main story board I just added a UIImageView inside the view</p>
