How do I mirror an NSAttributedString with an icon and text in right-to-left mode
I have a UIButton
that holds an NSAttributedString
that contains an icon (which is an NSAttributedString
itself) followed by a text.
It looks something like this:
I want to make it look like this when the device is configured for an RTL language (e.g. Arabic, Hebrew):
The string is built like this:
var iconText = NSAttributedString(fontName: fontName, fontSize: fontPointSize, fontValue: fontValue, color: color ?? iconColor)
let iconTextRange = NSRange(location: 0, length: iconText.count)
let iconAttrs: [NSAttributedString.Key: Any] = [.font: icon.font(pointSize: pointSize),
.foregroundColor: iconColor]
if !text.isEmpty {
iconText = "\(iconText) \(text)"
}
let attributeString = NSMutableAttributedString(string: iconText, attributes: textAttrs)
attributeString.addAttributes(iconAttrs, range: iconTextRange)
return attributeString
As you can see, first the icon is created using a font, then it's concatenated to the text.
In other parts of the app, I managed to make NSAttributedString
's RTL-compliant with this little piece of code:
public extension NSAttributedString {
/// Returns an identical attributed string that'll adjust its direction based on the device's configured language.
func rightToLeftAdjusted() -> NSAttributedString {
let paragraphStyle = NSMutableParagraphStyle()
paragraphStyle.baseWritingDirection = .natural
let attrs: [NSAttributedString.Key: Any] = [.paragraphStyle: paragraphStyle]
let range = NSRange(location: 0, length: length)
let copy = NSMutableAttributedString(attributedString: self)
copy.addAttributes(attrs, range: range)
return copy
}
}
Unfortunately, in this specific case, it doesn't seem to work, the star ALWAYS stays to the left of the text.
Are there any other ways of achieving this?
