NSAttributedString - add writing direction for Arabic Language

Question

I have an html content that i want to show on UILabel.

NSAttributedString *attrStr = [[NSAttributedString alloc] initWithData:[htmlString dataUsingEncoding:NSUnicodeStringEncoding] options:@{ 
NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType} 
documentAttributes:nil error:nil];
return attrStr;

This works good for English Language (LTR semantic), but since i want to support arabic as well the above method keeps the attributed string LTR. Inspite of using this code : self.view.semanticContentAttribute = UISemanticContentAttributeForceRightToLeft;

I've tried

NSMutableAttributedString *mutableAttributedString = [[NSMutableAttributedString alloc]initWithData:[htmlString dataUsingEncoding:NSUnicodeStringEncoding] options:@{ NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType} documentAttributes:nil error:nil];
[mutableAttributedString addAttribute:NSWritingDirectionAttributeName value:@[@(NSWritingDirectionRightToLeft | NSWritingDirectionOverride)] range:NSMakeRange(0, string.length)];
return mutableAttributedString;

Still the same. Any suggestions are welcome. Thanks

Hope will helpful to you for right side alignment!!

NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init];
paragraphStyle.lineBreakMode = NSLineBreakByWordWrapping;
paragraphStyle.alignment = NSTextAlignmentRight;

NSDictionary *attr = @{NSDocumentTypeDocumentAttribute: NSHTMLTextDocumentType,
                   NSCharacterEncodingDocumentAttribute: @(NSUTF8StringEncoding)};

NSError *error = nil;

NSMutableAttributedString *attributedText =
[[NSMutableAttributedString alloc]initWithData:[text dataUsingEncoding:NSUTF8StringEncoding] options:attr documentAttributes:nil error:&error];

[attributedText addAttribute:NSParagraphStyleAttributeName
                   value:paragraphStyle
                   range:NSMakeRange(0, attributedText.length)];
return attributedText;
