OR Associate custom UILabel class on Storyboard as Label's class.

I edited a little in the accepted answer. There is a problem when <code>leftInset</code> and <code>rightInset</code> increase, a part of text will be disappeared, b/c the width of label will be narrowed but the height does not increase as figure:

<a href="https://i.stack.imgur.com/7nJjz.jpg" rel="noreferrer"><img src="https://i.stack.imgur.com/7nJjz.jpg" alt="padding label with wrong intrinsic content size"></a>

To resolve this problem you need to re-calculate height of text as follow:

<pre><code>@IBDesignable class PaddingLabel: UILabel {

 @IBInspectable var topInset: CGFloat = 20.0
 @IBInspectable var bottomInset: CGFloat = 20.0
 @IBInspectable var leftInset: CGFloat = 20.0
 @IBInspectable var rightInset: CGFloat = 20.0

 override func drawTextInRect(rect: CGRect) {
 let insets = UIEdgeInsets(top: topInset, left: leftInset, bottom: bottomInset, right: rightInset)
 super.drawTextInRect(UIEdgeInsetsInsetRect(rect, insets))
 }

 override func intrinsicContentSize() -&gt; CGSize {
 var intrinsicSuperViewContentSize = super.intrinsicContentSize()

 let textWidth = frame.size.width - (self.leftInset + self.rightInset)
 let newSize = self.text!.boundingRectWithSize(CGSizeMake(textWidth, CGFloat.max), options: NSStringDrawingOptions.UsesLineFragmentOrigin, attributes: [NSFontAttributeName: self.font], context: nil)
 intrinsicSuperViewContentSize.height = ceil(newSize.size.height) + self.topInset + self.bottomInset

 return intrinsicSuperViewContentSize
 }
}
</code></pre>

and result:

<a href="https://i.stack.imgur.com/gDAMu.jpg" rel="noreferrer"><img src="https://i.stack.imgur.com/gDAMu.jpg" alt="padding label with right intrinsic content size"></a>

I hope to help some people in the same situation as me.

Swift 3 Code with Implementation Example

<pre><code>class UIMarginLabel: UILabel {

 var topInset: CGFloat = 0
 var rightInset: CGFloat = 0
 var bottomInset: CGFloat = 0
 var leftInset: CGFloat = 0

 override func drawText(in rect: CGRect) {
 let insets: UIEdgeInsets = UIEdgeInsets(top: self.topInset, left: self.leftInset, bottom: self.bottomInset, right: self.rightInset)
 self.setNeedsLayout()
 return super.drawText(in: UIEdgeInsetsInsetRect(rect, insets))
 }
}

class LabelVC: UIViewController {

 //Outlets
 @IBOutlet weak var labelWithMargin: UIMarginLabel!

 override func viewDidLoad() {
 super.viewDidLoad()

 //Label settings.
 labelWithMargin.leftInset = 10
 view.layoutIfNeeded()
 }
}
</code></pre>

Don't forget to add class name UIMarginLabel in storyboard label object.
Happy Coding!

 open override var intrinsicContentSize: CGSize {

Similar to other answers, but with a func class to setup the padding dinamically:

<pre><code>class UILabelExtendedView: UILabel
{
 var topInset: CGFloat = 4.0
 var bottomInset: CGFloat = 4.0
 var leftInset: CGFloat = 8.0

 override func drawText(in rect: CGRect)
 {
 let insets: UIEdgeInsets = UIEdgeInsets(top: topInset, left: leftInset, bottom: bottomInset, right: rightInset)
 super.drawText(in: UIEdgeInsetsInsetRect(rect, insets))
 }

 override public var intrinsicContentSize: CGSize
 {
 var contentSize = super.intrinsicContentSize
 contentSize.height += topInset + bottomInset
 contentSize.width += leftInset + rightInset
 return contentSize
 }

 func setPadding(top: CGFloat, left: CGFloat, bottom: CGFloat, right: CGFloat){
 self.topInset = top
 self.bottomInset = bottom
 self.leftInset = left
 self.rightInset = right
 let insets: UIEdgeInsets = UIEdgeInsets(top: top, left: left, bottom: bottom, right: right)
 super.drawText(in: UIEdgeInsetsInsetRect(self.frame, insets))

entityMap|blocks|key|922a5|text|一种实用的解决方案是添加与主标签相同高度和颜色的空白标签。将主标签的前导/尾随空格设置为零，垂直居中对齐，并将宽度设置为所需的边距。|type|unstyled|depth|inlineStyleRanges|entityRanges|data^0^^$0|$]|1|@$2|3|4|5|6|7|8|C|9|@]|A|@]|B|$]]]]

One pragmatic solution is to add blank labels of the same height and color as the main label. Set the leading/trailing space to the main label to zero, align vertical centers, and make the width your desired margin.

entityMap|blocks|key|b2j9i|text|无子类化的另一种选择是：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|6aa8q|设置标签text|ordered-list-item|offset|length|style|CODE|ebo44|sizeToFit()|9mjcm|然后稍微增加标签高度以模拟填充label.text+=+"someText“label.textAlignment+=+.center+label.sizeToFit()+label.frame+=+CGRect(+x:+label.frame.x，y:+label.frame.y，宽度:+label.frame.width+%2B+20，高度:+label.frame.height+%2B+8)^0|0|4|4|0|0|B|0^^$0|$]|1|@$2|3|4|5|6|7|8|N|9|@]|A|@]|B|$]]|$2|C|4|D|6|E|8|O|9|@$F|P|G|Q|H|I]]|A|@]|B|$]]|$2|J|4|K|6|E|8|R|9|@$F|S|G|T|H|I]]|A|@]|B|$]]|$2|L|4|M|6|E|8|U|9|@]|A|@]|B|$]]]]

Another option without subclassing would be to:

<ol>
<li>Set label <code>text</code></li>
<li><code>sizeToFit()</code></li>
<li>then increase label height a little to simulate padding

<pre><code>label.text = "someText"
label.textAlignment = .center 
label.sizeToFit() 
label.frame = CGRect( x: label.frame.x, y: label.frame.y,width: label.frame.width + 20,height: label.frame.height + 8)

Just use a UIButton, its already built in. Turn off all the extra button features and you have a label that you can set edge instets on.

button.contentEdgeInsets = UIEdgeInsets(top: 5, left: 5, bottom: 5, right: 5)

button.tintColor = .white // this will be the textColor

If you don't want or need to use an @IBInspectable / @IBDesignable UILabel in Storyboard (I think those are rendered too slow anyway), then it is cleaner to use UIEdgeInsets instead of 4 different CGFloats.

 var padding = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: 0)

 public override func drawText(in rect: CGRect) {
 super.drawText(in: rect.inset(by: padding))
 }

 public override var intrinsicContentSize: CGSize {
 let size = super.intrinsicContentSize
 return CGSize(width: size.width + padding.left + padding.right,
 height: size.height + padding.top + padding.bottom)

Objective-C
Based on <a href="https://stackoverflow.com/a/32368958/9516941">Tai Le's answer</a>, which implements the feature inside an <a href="https://en.wikipedia.org/wiki/Interface_Builder" rel="nofollow noreferrer">Interface Builder</a> Designable, here's the Objective-C version.
Put this in YourLabel.h file:
<pre><code>@interface YourLabel : UILabel

@property IBInspectable CGFloat topInset;
@property IBInspectable CGFloat bottomInset;
@property IBInspectable CGFloat leftInset;
@property IBInspectable CGFloat rightInset;

@end
</code></pre>
And this would go in file YourLabel.m:
<pre><code>IB_DESIGNABLE

@implementation YourLabel

#pragma mark - Super

- (instancetype)initWithCoder:(NSCoder *)aDecoder {
 self = [super initWithCoder:aDecoder];
 if (self) {
 self.topInset = 0;
 self.bottomInset = 0;
 self.leftInset = 0;
 self.rightInset = 0;
 }
 return self;
}

- (void)drawTextInRect:(CGRect)rect {
 UIEdgeInsets insets = UIEdgeInsetsMake(self.topInset, self.leftInset, self.bottomInset, self.rightInset);
 [super drawTextInRect:UIEdgeInsetsInsetRect(rect, insets)];
}

- (CGSize)intrinsicContentSize {
 
 CGSize size = [super intrinsicContentSize];
 return CGSizeMake(size.width + self.leftInset + self.rightInset,
 size.height + self.topInset + self.bottomInset);
}

@end
</code></pre>
You can then modify YourLabel insets directly in Interface Builder after specifying the class inside the <a href="https://en.wikipedia.org/wiki/Interface_Builder" rel="nofollow noreferrer">XIB</a> file or storyboard, the default value of the insets being zero.

My solution is similar to what people answered but adds <code>sizeThatFits</code> to help <code>UIKit</code> to figure out the right size.
<pre><code>class InsetLabel : UILabel {
 @objc var textInsets: UIEdgeInsets = .zero

 override func drawText(in rect: CGRect) {
 super.drawText(in: rect.inset(by: textInsets))
 }

 override func sizeThatFits(_ size: CGSize) -&gt; CGSize {
 var s = super.sizeThatFits(CGSize(width: size.width - (textInsets.left + textInsets.right), height: size.height - (textInsets.top + textInsets.bottom)))
 s.height += textInsets.top + textInsets.bottom
 return s
 }
}
</code></pre>

I have a <code>UILabel</code> where I want to add space in the top and in the bottom. With the minimum height in constraints, I've modified it to:
<img src="https://i.stack.imgur.com/ccEWr.png" alt="Enter image description here" />
To do this I've used:
<pre><code>override func drawTextInRect(rect: CGRect) {
 var insets: UIEdgeInsets = UIEdgeInsets(top: 0.0, left: 10.0, bottom: 0.0, right: 10.0)
 super.drawTextInRect(UIEdgeInsetsInsetRect(rect, insets))
}
</code></pre>
But I've to find a different method because if I write more than two lines, the problem is the same:
