title: How to add an integer value into NSMutableArray?
body: <pre><code>NSMutableArray * val;
  val = [[NSMutableArray alloc] initWithCapacity:15];
  
  /*int outlineWidth = barOutlineWidth;
  int outlineHalfWidth = (outlineWidth &gt; 1) ? outlineWidth * 0.5f : 0;
   */
  for ( Bar * obj in values )
  {  
    // calcualte the bar size
    float value  = [obj value];
    float scale  = ( value / maxValue );
  
    // shift the bar to the top or bottom of the render line
    int pointY   = lineHeight + ( (lineWidth * 0.5f) * ( ( value &gt;= 0.0f ) ? -1 : 1 ) );
    int barHeight = height * scale;
    NSLog(@"%d", barHeight);   
    CGRect barRect = CGRectMake(pointX, pointY, width, -barHeight);
    [val addObject:[NSNumber numberWithInt:barHeight]];
                       NSLog(@"%d", val);

  <p>I want to add the barheight (int) into array val. 
  Is this possible?
  while running the code,</p>

  <p>this is the output.</p>
  
  <p>Here the actual barheights are 78,235,156,
  while printing the array val.</p>
  
  <p>Im getting like values like "69398112"</p>
  
  <p>What should I do?</p>
