Make UILabel text Right Aligned if the text is in Arabic

I have implemented Language Localization in my iOS App. So, now user can set the Arabic Language in my iPad Application.

I am getting the localized string response from the server and now I want to set this localized string to my UILabel in Right To Left format with Right Alignment.

Update :

My server response is already in RTL format. Now, I just wanted to set the text alignment to right when I have Arabic text in my UILabel.

Right now I have to write code to set the alignment of UILabel based on the language.

So, I just want to know if there is any property available for UILabel by setting which I can make the text of UILabel Right Aligned in case of Arabic Language.

For anyone wanting an example using the NaturalLanguage library (NSLinguisticTagger is deprecated). This builds on @jaspreetkour's answer, and also works with attributed text.

extension UILabel {

    func decideTextDirection () {
        let recognizer = NLLanguageRecognizer()
        var txt = self.text ?? ""
        if txt.isEmpty {
            // check attributed text
            txt = self.attributedText?.string ?? ""
        }
        if !txt.isEmpty {
            recognizer.processString(txt)
            if let language = recognizer.dominantLanguage {
                switch language {
                case .arabic:
                    self.textAlignment = .right
                default:
                    self.textAlignment = .left
                }
            }
        }
    }
}

For Swift3 //MARK: UILabel extension

extension UILabel {
func decideTextDirection () {
    let tagScheme = [NSLinguisticTagSchemeLanguage]
    let tagger    = NSLinguisticTagger(tagSchemes: tagScheme, options: 0)
    tagger.string = self.text
    let lang      = tagger.tag(at: 0, scheme: NSLinguisticTagSchemeLanguage,
                                      tokenRange: nil, sentenceRange: nil)

    if lang?.range(of:"ar") != nil {
        self.textAlignment = NSTextAlignment.right
    } else {
        self.textAlignment = NSTextAlignment.left
    }
}

to use this add following with your label :

detailLabel.text = details[0]

detailLabel.decideTextDirection()

Make your text label the entire width of the view. Then the text will right align from the right side of the screen.

have you try this. 

 [[self label] setTextAlignment:NSTextAlignmentNatural];

AutoLayout + RTL + UILabel text alignment

Hope this will solve your problem.

Display the text normally as you do in english if you are getting arabic text from server no need to align it. Just right align the text.
