NSAttributedString with fonts, paragraph Style, line spacing using NSMutableAttributedString

// create a Attributed string and adding different parameters like font, paragraph Style, etc

    // Create UIFont -

    UIFont *systemFont = [UIFont fontWithName:@"HelveticaNeue-Light" size:17.0];

    // Create a paragraphStyle -

    NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init];

    paragraphStyle.maximumLineHeight = 45;

    paragraphStyle.minimumLineHeight = 30;

    paragraphStyle.lineSpacing = 15;

    paragraphStyle.lineHeightMultiple = 10;

    

    // create a dictionary of Attributed -

    NSDictionary * fontAttributes = [[NSDictionary alloc] initWithObjectsAndKeys:systemFont,  NSFontAttributeName,NSParagraphStyleAttributeName,paragraphStyle, nil];

    

    // create a Attributed  string and adding parameters dictionary-

    NSMutableAttributedString *libTitle = [[NSMutableAttributedString alloc] initWithString:@"Hello there, \n" attributes:fontAttributes];

    

    // create second Attributed  string with different font-

    UIFont *subTextFont = [UIFont fontWithName:@"HelveticaNeue-Thin" size:15.0];

    NSDictionary * subTitlefontAttributes = [[NSDictionary alloc] initWithObjectsAndKeys:subTextFont, NSFontAttributeName,, nil];

    NSMutableAttributedString *subTitleString = [[NSMutableAttributedString alloc] initWithString:@"MacOS & iOS developments tips" attributes: subTitlefontAttributes];

    

    // Append Attributed string and create a single string-

    [libTitle appendAttributedString: subTitleString];

    // Set Attributed string on the label

    [self.myLabel setAttributedText:libTitle];
