ios - barButtonItem操作异常

我在viewDidLoad方法中设置navigationBarItem

var button = UIBarButtonItem(title: "Menu", style: UIBarButtonItemStyle.Bordered, target: self, action: Selector("goToMenu:"))
self.navigationItem.rightBarButtonItem = button

我有一个方法可以选择此按钮操作

func goToMenu() {
    var destinationViewController = UIStoryboard(name: "Main", bundle: nil).instantiateViewControllerWithIdentifier("menuBoard") as MenuViewController
    self.navigationController?.presentViewController(destinationViewController, animated: true, completion: nil)
}

但我有例外

goToMenu:]: unrecognized selector sent to instance 0x15678990'

我做错了什么？

最佳答案

修改代码为：

func goToMenu(sender: AnyObject) {
    var destinationViewController = UIStoryboard(name: "Main", bundle: nil).instantiateViewControllerWithIdentifier("menuBoard") as MenuViewController
    self.navigationController?.presentViewController(destinationViewController, animated: true, completion: nil)
}

原因是您的Selector("goToMenu:")寻找带有一个参数的方法，但是您的goToMenu实际上没有参数
