NSMutableAttributedStringを使用する

小さな例

let yourAttributes = [NSForegroundColorAttributeName: UIColor.blackColor(), NSFontAttributeName: UIFont.systemFontOfSize(15)]
let yourOtherAttributes = [NSForegroundColorAttributeName: UIColor.redColor(), NSFontAttributeName: UIFont.systemFontOfSize(25)]

let partOne = NSMutableAttributedString(string: "This is an example ", attributes: yourAttributes)
let partTwo = NSMutableAttributedString(string: "for the combination of Attributed String!", attributes: yourOtherAttributes)

let combination = NSMutableAttributedString()

combination.appendAttributedString(partOne)
combination.appendAttributedString(partTwo)

スイフト3

let yourAttributes = [NSForegroundColorAttributeName: UIColor.black, NSFontAttributeName: UIFont.systemFont(ofSize: 15)]
let yourOtherAttributes = [NSForegroundColorAttributeName: UIColor.red, NSFontAttributeName: UIFont.systemFont(ofSize: 25)]

let partOne = NSMutableAttributedString(string: "This is an example ", attributes: yourAttributes)
let partTwo = NSMutableAttributedString(string: "for the combination of Attributed String!", attributes: yourOtherAttributes)

let combination = NSMutableAttributedString()

combination.append(partOne)
combination.append(partTwo)

combinationは、yourAttributesとyourOtherAttributesによって提供される両方のフォーマットを含む最終的な文字列を表します

@ glace's answer 、空のNSMutableAttributedString宣言を避けるために修正。 Swift 3.1で有効：

let yourAttributes = [NSForegroundColorAttributeName: UIColor.blackColor(), NSFontAttributeName: UIFont.systemFontOfSize(15)]
let yourOtherAttributes = [NSForegroundColorAttributeName: UIColor.redColor(), NSFontAttributeName: UIFont.systemFontOfSize(25)]

let partOne = NSMutableAttributedString(string: "This is an example ", attributes: yourAttributes)
let partTwo = NSMutableAttributedString(string: "for the combination of Attributed String!", attributes: yourOtherAttributes)

partOne.append(partTwo)

partOneは、すべての属性を含む最終的な文字列です。中間の「コンバイナ」は必要ありません。

Swift 4

let yourAttributes: [NSAttributedString.Key: Any] = [.foregroundColor: UIColor.black, .font: UIFont.systemFont(ofSize: 15)]
let yourOtherAttributes: [NSAttributedString.Key: Any] = [.foregroundColor: UIColor.red, .font: UIFont.systemFont(ofSize: 25)]

let partOne = NSMutableAttributedString(string: "This is an example ", attributes: yourAttributes)
let partTwo = NSMutableAttributedString(string: "for the combination of Attributed String!", attributes: yourOtherAttributes)

partOne.append(partTwo)

「グレイス」の回答に従って、フォント属性とSwiftバージョンを更新するだけです。

    let boldFontAttributes = [NSAttributedString.Key.foregroundColor: UIColor.black, NSAttributedString.Key.font: UIFont.boldSystemFont(ofSize: 17)]
    let normalFontAttributes = [NSAttributedString.Key.foregroundColor: UIColor.darkGray, NSAttributedString.Key.font: UIFont.systemFont(ofSize: 15)]
    let partOne = NSMutableAttributedString(string: "This is an example ", attributes: boldFontAttributes)
    let partTwo = NSMutableAttributedString(string: "for the combination of Attributed String!", attributes: normalFontAttributes)

    let combination = NSMutableAttributedString()

    combination.append(partOne)
    combination.append(partTwo)
    lblUserName.attributedText = combination

拡張機能を使用して、

extension NSMutableAttributedString{
    func getAttributedStringByAppending(attributedString:NSMutableAttributedString) -> NSMutableAttributedString{
        let newAttributedString = NSMutableAttributedString()
        newAttributedString.append(self)
        newAttributedString.append(attributedString)
        return newAttributedString
    }
}

使用法：attributedString1、attributedString2は2つのNSMutableAttributedStringであり、

let combinedAttributedString = attributedString1.getAttributedStringByAppending(attributedString: attributedString2)
