title: Add padding into UIlabel text?
body: <p>I've a label in a table cell and I wish to add padding to top,bottom,left and right.</p>
  <pre><code>CGRect initialFrame = CGRectMake(10,10,100,20);
  UIEdgeInsets contentInsets = UIEdgeInsetsMake(5, 0, 5, 0);
  CGRect padd = UIEdgeInsetsInsetRect(initialFrame, contentInsets);
  self.rewardLabel = [[UILabel alloc] initWithFrame:padd];
  self.rewardLabel.backgroundColor =[UIColor colorWithRed:0.192 green:0.373 blue:0.561 alpha:1];
  self.rewardLabel.layer.cornerRadius = 5.0f;
  self.rewardLabel.layer.masksToBounds = YES;
  self.rewardLabel.textColor = [UIColor whiteColor];
  self.rewardLabel.lineBreakMode = NSLineBreakByWordWrapping;
  self.rewardLabel.numberOfLines = 1;
  self.rewardLabel.font = [UIFont fontWithName:@&quot;HelveticaNeue&quot; size:14];
  [self.contentView addSubview:self.rewardLabel];    
  </code></pre>
  <p>But it seem like not working. Can anyone tell me how to do?</p>
