Swift导航栏项目未调用操作 [英] Swift Navigation Bar item not calling action

问题描述

我在导航栏上有一个调用动作的项目.它停止工作了.我已从操作中断开该项目并重新连接.仍然没有动作.动作附在情节提要中.如何调试或解决此问题?

I have an item on the navigation bar that calls an action. It stopped working. I have disconnected the item from the action and re-attached. Still no action. The action is attached in the storyboard. How do I debug or solve this issue?

推荐答案

尝试类似的方法

如果有参数

 override func viewDidLoad() {
    super.viewDidLoad()

    self.navigationItem.rightBarButtonItem = UIBarButtonItem(title: "ButtonName", style: .done, target: self, action: #selector(YourViewController.yourAction(_:)))

}

无参数

 override func viewDidLoad() {
    super.viewDidLoad()

    self.navigationItem.rightBarButtonItem = UIBarButtonItem(title: "ButtonName", style: .done, target: self, action: #selector(YourViewController.yourAction))

}
