Underline covers text in NSAttributedString

Question

I'm trying to create an attributed string but the underline covers my text instead of appearing behind it: Is there a way to fix this? I'm using the following code: ``` let paragraphStyle = NSMutableParagraphStyle() paragraphStyle.lineSpacing = 10.0 let attributes = [NSForegroundColorAttributeName: UIColor.white, NSUnderlineStyleAttributeName: NSUnderlineStyle.styleThick.rawValue, NSUnderlineColorAttributeName: UIColor.red, NSParagraphStyleAttributeName: paragraphStyle] let attributedString = NSAttributedString(string: "Story", attributes: attributes) ``` Thanks! EDIT: To give more context: I'm displaying the attributed string on a UILabel placed in a .xib file: ``` view.textLabel.attributedText = attributedString ``` The label has the following font: System Bold 32.0 I'm running the code on iPhone 6 - iOS 10.3 simulator. EDIT 2: I should have mentioned that the label may, at some point, contain more than one line of text. That's why the numberOfLines is set to 0. EDIT 3: If anybody e…

Accepted Answer

Yes, there is such problem as you have described. It shows up when you use multiline `UILabel`, so not only setting `numberOfLines` to 0, but type more than 1 line in it.

Example

```
let selectedStringAttributes: [String: Any]
    = [NSFontAttributeName: UIFont.boldSystemFont(ofSize: 28),
       NSForegroundColorAttributeName: UIColor.green,
       NSUnderlineStyleAttributeName: NSUnderlineStyle.styleSingle.rawValue,
       NSUnderlineColorAttributeName: UIColor.green]

let label = UILabel(frame: CGRect(x: 100, y: 100, width: 500, height: 100))
label.numberOfLines = 0

label.attributedText = NSAttributedString(string: "String to test underline", attributes: selectedStringAttributes)
```

And everything will look pretty good.

But if you want to use such text:

```
label.attributedText = NSAttributedString(string: "String to
test underline", attributes: selectedStringAttributes)
```

or label's width is too short, than:

So the reason for such behaviour is of course bug in `NSAttributedString`. As it mentioned in radar there is a workaround

You should add this attribute to your `NSAttributedString`

```
NSBaselineOffsetAttributeName: 0
```

And magic will happen.
