将字体大小和自定义字体名称添加到UITextView中的属性字符串

Question

I have the following code to add the attributed string to the UITextView text. I need to add the custom font and font size to it in swift. How to do it?

    func setAttributedString(string: String) -> NSAttributedString {
    let attrString = NSMutableAttributedString(string: string)
    let paragraphStyle = NSMutableParagraphStyle()
    paragraphStyle.lineSpacing = 7
    paragraphStyle.minimumLineHeight = 7
    attrString.addAttribute(NSParagraphStyleAttributeName, value:paragraphStyle, range:NSRange(location: 0, length:attrString.length))
    attrString.addAttribute(NSFontAttributeName, value: UIFont.systemFont(ofSize: 30), range: NSRange(location: 0, length:attrString.length))
    return attrString
  }

I need to add the custom font and font size to the following function. How to achieve this?

Answer 1

In Swift 3

let attributes = [NSAttributedStringKey.font: UIFont(name: "HelveticaNeue-Bold", size: 17)!, 
              NSAttributedStringKey.foregroundColor: UIColor.white]

let attributedString  = NSMutableAttributedString(string: "Your string" , attributes: attributes)

Answer 2

Use the initializer init(string:attributes:)

https://developer.apple.com/documentation/foundation/nsattributedstring/1408136-init

let attrString = NSMutableAttributedString(string: string, attributes:
            [NSFontAttributeName:UIFont(
            name: "Georgia",
            size: 18.0)!])
    //Add more attributes here
