如何在单个UILabel文本上获得两个普通字符串和NSMutableString？

Question

我希望修改单个UILabel文本，如下所示。

如何使用NSMutableString或UILabel的attributedText属性完成它？帮助感谢。

注意：姓名＆＃39; John Doe＆＃39;是从API派生的用户帐户名称。

Answer 1

请参阅此示例，添加相应的Attribute。

let text = NSMutableAttributedString(string: "Welcome John Doe")
text.addAttribute(NSFontAttributeName, value: UIFont(name: "YourFont", size: 18)!, range: NSMakeRange(8, text.characters.count - 8))
label.attributedText = text

Answer 2

您可以使用属性字符串：

let text = "Welcome John Doe"
let textWithColor = "John Doe"
let range = text.rangeOfString(textWithColor)

let attributedString = NSMutableAttributedString(string:text)
attributedString.addAttribute(NSForegroundColorAttributeName, value: UIColor.orangeColor() , range: range)

label.attributedText = attributedString

我修改了Ronit的答案并在下面分享。

var userNameString:String?

    override func viewWillAppear(animated: Bool) {

        self.makeAttributedUserNameTitleLabelText()
    }
    func makeAttributedUserNameTitleLabelText()
    {
        userNameString = "John Doe"
        let text = "Welcome  "+userNameString!
        let range =  NSMakeRange(8, text.characters.count - 8)
        let attributedString = NSMutableAttributedString(string:text)
        attributedString.addAttribute(NSForegroundColorAttributeName, value: UIColor.orangeColor(), range: range)
        attributedString.addAttribute(NSFontAttributeName, value: UIFont(name: "Roboto-Bold", size: 14)!, range: range)
        self.userNameTitleLabel.attributedText = attributedString

    }

Answer 4

info.name = "John Doe" //which come from api

let nameValue = "Welcome " + "\(info.name!)" 

let bSerString = "\(info.name!)" 

let nameAttribt = NSMutableAttributedString(string: nameValue)
let bSRange = nameValue.rangeOfString(bSerString as String)

nameAttribt.addAttribute(NSFontAttributeName, value: UIFont(name: "OpenSans-Semibold", size: 14)!, range: bSRange)

nameAttribt.addAttribute(NSForegroundColorAttributeName, value: UIColor.orangeColor(), range: bSRange)

self.lblName.attributedText = nameAttribt
