title: How to add horizontal spacing and vertical spacing programmatically in ios?
body: <p>I have created an app in ios 8. In that I have 4 labels which are available as vertically (it should change the position for certain conditions), I have disabled auto layout and setting constraints programmatically. Now, the problem is however I can set constraints for horizontal and vertical positions, width and height, I could not find any way to add constraints for horizontal and vertical spacing between the labels.</p>
  
  <p>Can anyone please help me to do this.</p>
  
  <p>So far I have the following code:</p>
  
  <pre><code>NSArray *constraint_V_WebUrl = [NSLayoutConstraint constraintsWithVisualFormat:@"V:[weburl(31)]" options:0 metrics:nil views:contentDictionary];
      NSArray *constraint_H_WebUrl = [NSLayoutConstraint constraintsWithVisualFormat:@"H:[weburl(196)]" options:0 metrics:nil views:contentDictionary];
      NSArray *constraint_POS_H_WebUrl = [NSLayoutConstraint constraintsWithVisualFormat:@"H:|-13-[weburl]" options:0 metrics:nil views:contentDictionary];
  [self.cardDetails addConstraints:constraint_POS_V_WebUrl];
      [self.cardDetails addConstraints:constraint_POS_H_WebUrl];
  [self.cardDetails addConstraint:[NSLayoutConstraint constraintWithItem:self.weburl attribute:NSla relatedBy:NSLayoutRelationEqual toItem:self.cardDetails attribute:NSLayoutAttributeTopMargin multiplier:1 constant:0.0]];
  </code></pre>
  
  <p>Code above works fine. But I want to set horizontal and vertical spacing between the labels.</p>
