swift - 带有字符串插值的属性字符串不起作用(swift)

Question

我想在字符串插值中使用属性字符串。但它的工作原理如屏幕截图中所示。属性字符串的格式不正确。为什么会发生这种情况？有没有其他方法可以解决这个问题？

@IBOutlet weak var denemeLabel: UILabel!

    override func viewDidLoad() {
        super.viewDidLoad()


        var nameString: String = "any String"
            denemeLabel.text = ""

            let nameAttribute = [NSAttributedString.Key.font: UIFont(name: "Chalkduster", size: 18)]
            let attributedNameString = NSMutableAttributedString(string: nameString, attributes: nameAttribute)

            let nsAttributedString =  NSMutableAttributedString(string:"\(attributedNameString) another String")
            denemeLabel.attributedText = nsAttributedString

    }

Xcode 10.1 Swift 4.2

var nameString: String = "any String"

// Set Attributes for the first part of your string
let att1 = [NSAttributedString.Key.font : UIFont(name: "Chalkduster", size: 18.0)]

// Set Attributes for the second part of your string
let att2 = [NSAttributedString.Key.font : UIFont.systemFont(ofSize: 18)]

// Create the first part of your attributed string
let attributedString1 = NSMutableAttributedString(string: nameString, attributes: att1)

// Create the second part of your attributed string
let attributedString2 = NSMutableAttributedString(string: "another String", attributes: att2)

// Append the second string to the end of the first string
attributedString1.append(attributedString2)

// Update your label
denemeLabel.attributedText = attributedString1
