title: CGRect Center for Ipad
body: <p>I am creating an image frame using CGRect. I want to center the rectangle that is created. </p>
  
  <p>I've looked on here, as well as in the Apple documentation for the best way to do this, and found CGRectGetMidY and CGRectGetMidX which get the center coordinates.</p>
  
  <p>When I try implementing this into my own code I run into problems. I get a Property size not found on object of type UIIMageView error</p>
  
  <pre><code>       #import "MyViewController.h"
  
  
  
      @interface MyViewController ()
  
      @end
  
      @implementation MyViewController
  
      @synthesize mySignatureImage;
      @synthesize lastContactPoint1, lastContactPoint2, currentPoint;
      @synthesize imageFrame;
      @synthesize fingerMoved;
      @synthesize navbarHeight;
  
      - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
      {
          self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
          if (self) {
              // Custom initialization
          }
          return self;

          [super viewDidLoad];
  
  
  
          self.view.backgroundColor = [UIColor lightGrayColor];
  
          CGRect mySignatureImageFrame = CGRectMake(
                                         CGRectGetMidX(self.view.frame) - (mySignatureImage.size.width/ 2.0),
