title: UITextView inside UIAlertView subclass
body: <p>I'm trying to put a UITextView inside a custom subclass of UIAlertView that I create using a background image of mine. The UITextView is only for displaying large quantities of text (so the scrolling).
  Here is the code of my subclass</p>
  
  <pre><code>- (id)initNarrationViewWithImage:(UIImage *)image text:(NSString *)text{
      if (self = [super init]) {
          self.backgroundImage = image;  
          UITextView * textView = [[UITextView alloc] initWithFrame:CGRectZero];
          self.textualNarrationView = textView;
          [textView release];
          self.textualNarrationView.text = text;
          self.textualNarrationView.backgroundColor = [UIColor colorWithRed:0.0 green:1.0 blue:0.0 alpha:1.0];
          self.textualNarrationView.opaque = YES;
          [self addSubview:textualNarrationView];
      }
      return self;
  }
  
  - (void)drawRect:(CGRect)rect {
  
      NSLog(@"DRAU");
      CGSize imageSize = self.backgroundImage.size;
      [self.backgroundImage drawInRect:CGRectMake(0, 0, imageSize.width, imageSize.height)];
  }
  
  - (void)layoutSubviews {
  
  
      CGSize imageSize = self.backgroundImage.size;
      self.textualNarrationView.bounds = CGRectMake(0, 0, imageSize.width - 20, imageSize.height - 20);
      self.textualNarrationView.center = CGPointMake(320/2, 480/2);
  
  
  }
  
  - (void)show{
      [super show];
      NSLog(@"SCIO");
      CGSize imageSize = self.backgroundImage.size;
      self.bounds = CGRectMake(0, 0, imageSize.width, imageSize.height);
      self.center = CGPointMake(320/2, 480/2);
  }
  </code></pre>
  
  <p>This is my first time subclassing a UIView, I'm surely missing something since the background image appears correctly, the UITextview also but after a fraction of a second it jumps all up (seems like a coordinate problem).</p>
