無法識別的選擇器Swift 2 Purelayout Xcode7

Question

您好，無法識別的選擇器發送到實例異常時遇到了問題，我已經搜索了一下，但是找不到解決方案。

我相信我在使用PureLayout時會發生該錯誤，但仍不確定是什么引起了該問題。 一件奇怪的事情是，在使用迦太基制作我的purelayout框架之后，我必須使用一個奇怪的橋接頭來導入purelayout，通常您需要導入PureLayout.h，但是除非我在橋接頭中導入PureLayout_Ios / Purelayout.h，否則我的代碼將無法編譯。 。 因此，我必須在我的viewcontroller中導入PureLayout_iOS。

視圖：

var presenter: SignUpPresenterProtocol?
//lazy var logoImageView: UIImageView = UIImageView()
lazy var nextButton: UIButton = {
    var button = UIButton()
    button.backgroundColor = Styles.BUTTON_COLOR
    return button
}()

override func viewDidLoad() {
    super.viewDidLoad()
    self.setupSubviews()
    self.setupConstraints()
    self.setNeedsStatusBarAppearanceUpdate()
    self.presenter?.viewDidLoad()
}

private func setupSubviews()
{
    self.view.addSubview(self.nextButton)
    self.view.addSubview(self.userNameTextField)
    self.nextButton.addTarget(self, action: Selector("userDidSelectNext:"), forControlEvents: UIControlEvents.TouchUpInside)
    //self.view.addSubview(self.logoImageView)
}

private func setupConstraints()
{
    self.nextButton.translatesAutoresizingMaskIntoConstraints = false
    self.nextButton.autoMatchDimension(.Width, toDimension: .Width, ofView: self.view, withMultiplier: 0.8)
    self.nextButton.autoSetDimension(.Height, toSize: Styles.BUTTON_HEIGHT)
    self.nextButton.autoCenterInSuperview()x
}

func userDidSelectNext(sender: AnyObject)
{
    self.presenter?.userDidSelectNext()
}

這是錯誤堆棧跟蹤：

Answer 1

嘗試更換這條線...

 self.nextButton.addTarget(self, action: Selector("userDidSelectNext:"), forControlEvents: UIControlEvents.TouchUpInside)

與此相反...

 self.nextButton.addTarget(self, action: "userDidSelectNext:", forControlEvents: UIControlEvents.TouchUpInside)

Answer 2

使用迦太基更新我的purelayout庫后，它已修復，但不確定是什么問題，這是github上的最新changlog 。
