Supporting RTL languages

[LogiStack]

The expandableLabel's textAlignment is always .left without referring textAlignment property.

I've set it to .Right or .Natural, but the label shows the text always as .Left

Please help me solve this issue.

I fixed the issue by changing some code in Library. Notes : when ever you update your pods you must have to change this code again this might be the drawback

1. Open the "ExpandableLabel.swift" file.

2. Initialise a variable in the class. i.e open var customTextAlignment: NSTextAlignment?

3. Replace copyWithParagraphAttribute function with following function

   func copyWithParagraphAttribute(_ font: UIFont,_ alignment: NSTextAlignment) -> NSAttributedString {
       let paragraphStyle = NSMutableParagraphStyle()
       paragraphStyle.lineHeightMultiple = 1.05
       paragraphStyle.alignment = alignment
       paragraphStyle.lineSpacing = 0.0
       paragraphStyle.minimumLineHeight = font.lineHeight
       paragraphStyle.maximumLineHeight = font.lineHeight
   
       let copy = NSMutableAttributedString(attributedString: self)
       let range = NSRange(location: 0, length: copy.length)
       copy.addAttribute(.paragraphStyle, value: paragraphStyle, range: range)
       copy.addAttribute(.baselineOffset, value: font.pointSize * 0.08, range: range)
       return copy
   }

4. Replace the attributedText variable with following code

   open override var attributedText: NSAttributedString? {
       set(attributedText) {
           if let attributedText = attributedText?.copyWithAddedFontAttribute(font).copyWithParagraphAttribute(font, self. customTextAlignment ?? .left),
               attributedText.length > 0 {
               self.collapsedText = getCollapsedText(for: attributedText, link: (linkHighlighted) ? collapsedAttributedLink.copyWithHighlightedColor() : self.collapsedAttributedLink)
               self.expandedText = getExpandedText(for: attributedText, link: (linkHighlighted) ? expandedAttributedLink?.copyWithHighlightedColor() : self.expandedAttributedLink)
               super.attributedText = (self.collapsed) ? self.collapsedText : self.expandedText
           } else {
               self.expandedText = nil
               self.collapsedText = nil
               super.attributedText = nil
           }
       }
       get {
           return super.attributedText
       }
   }

5. Clean the build folder

6. Set the alignment of label in your class label.customTextAlignment = .center
