title: How to catch event of switch changed in custom tableViewCell?
body: <p>I have a question ... </p>
  
  <p>I have Custom TableViewCell class:</p>
  
  <pre><code>// Class for Custom Table View Cell.
  @interface CustomTableViewCell : UITableViewCell {
      // Title of the cell.
      UILabel*     cellTitle;
      // Switch of the cell.
      UISwitch*    cellSwitch;
  }
  </code></pre>
  
  <p>How you can see in my custom UITableViewCell I have Label and Switch controller.</p>
  
  <pre><code>- (id)initWithStyle: (UITableViewCellStyle)style reuseIdentifier: (NSString *)reuseIdentifier tableType:(TableTypeEnumeration)tabletypeEnum {
          // Get Self.
          self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
          if (self) {
              // Create and initialize Title of Custom Cell.
              cellTitle = [[UILabel alloc] initWithFrame:CGRectMake(10, (44 - TAGS_TITLE_SIZE)/2, 260, 21)];
              cellTitle.backgroundColor      = [UIColor clearColor];
              cellTitle.opaque               = NO;
              cellTitle.textColor            = [UIColor blackColor];
              cellTitle.highlightedTextColor = [UIColor whiteColor];
              cellTitle.font                 = [UIFont boldSystemFontOfSize:TAGS_TITLE_SIZE];
              cellTitle.textAlignment        = UITextAlignmentLeft;
              // Create and Initialize Switch of Custom Cell.
              cellSwitch = [[UISwitch alloc] initWithFrame:CGRectMake(185, 10, 10, 10 )];
  
              [self.contentView addSubview:cellTitle];
              [self.contentView addSubview:cellSwitch];
  
              [cellTitle release];
              [cellSwitch release];
          }
          return self;
  }
  </code></pre>
