  <p>my code is as follows:</p>
  
  <pre><code>-(UIView *)createView:(NSArray *)_data{
  
      UIView *_view = [[UIView alloc ] initWithFrame:CGRectMake(0, 0, 1024, 768)];
      pageData = [[NSMutableArray alloc] init]; 
      self.imageData = _data;
      [_view setBackgroundColor:[UIColor colorWithRed:1.0 green:1.0 blue:0 alpha:1.0]];
      [self addSubview:_view];
  
      UIButton *_button1= [[UIButton buttonWithType:UIButtonTypeRoundedRect] retain];
      _button1.frame = CGRectMake(110.0, 360.0, 100.0, 30.0);
      [_button1 setTitle:@"Play" forState:UIControlStateNormal];
      _button1.backgroundColor = [UIColor clearColor];
      [_button1 addTarget:self action:@selector(buttonClicked:) forControlEvents:UIControlEventTouchUpInside];
      [_view addSubview:_button1];  
  
      [_button1 release];
      [_view release];
  
      return _view;
  }
  
  - (IBAction)buttonClicked:(id)sender
  {
      NSLog(@"Hi!");
  }
  </code></pre>
  
  <p>I can't for the life of me figure out what is going on here...
  Any help or insight would be greatly appreciated!
  Thanks</p>
