title: Custom UI View Change frame size
body: <p>I have a custom UIView that draws an image in the draw rect method.  My problem is UIView wants me to initWithFrame when I allocate the object.  The frame of the view needs to be the same as the image size and width.  The problem is that I don't get that image size and width until the drawRect method of the view I am creating.  Inside the drawRect view changing the UIView's frame to the image dimensions seems to have no effect.  So what I want to do is something like this:</p>
  
  <pre><code>MyCustomView *myCustomView = [[MyCustomView alloc] initWithFrame: CGrectMake(0,0,0,0)];
  </code></pre>
  
  <p>Then inside MyCustomView's drawRect method I want to somehow change the frame of the view to be the frame size of the image I am creating.</p>
  
  <p>How do I get my desired outcome? An no, creating the image before I init my custom view and putting the size dimensions into the initWithFrame is not an option.</p>
  
  <p>This is my current code in the view's drawRect method</p>
  
  <pre><code>UIImage *image = [UIImage imageNamed:[NSString stringWithFormat:@"%@",self.imgName]];
  CGSize imgSize = [image size];
  CGRect newrect = CGRectMake(self.frame.origin.x, self.frame.origin.y, imgSize.width, imgSize.height);
  self.frame = newrect; //This does nothing!!
  CGRect imgRect = CGRectMake(0, 0, imgSize.width, imgSize.height);
  [image drawInRect:imgRect];
  </code></pre>
