无法将类型为uibutton的值转换为预期的参数字符串

Question

我一直试图在YouTube上的指南中创建一个共享按钮，然而我收到的错误对我来说没有意义 “无法转换类型的值（VideoViewController） - >（的UIButton） - >（）预期参数 “字符串” 在这行代码：

cell.shareButton.addTarget(self, action: Selector(VideoViewController.shareAction(_:)), forControlEvents: .TouchUpInside) 

我的继承人按钮代码

@IBAction func shareAction(sender: UIButton) 
{ 
    let post = timelineComponent.content[sender.tag] 
    let titleString = post.labelTitle 

    let firstActivityItem = "\(titleString)" 

    let activityViewController : UIActivityViewController = UIActivityViewController(activityItems: [firstActivityItem], applicationActivities: nil) 

    self.presentViewController(activityViewController, animated: true, completion: nil) 

} 

Answer 1

尝试这样，它应该工作

cell.shareButton.addTarget(self, action: #selector(VideoViewController.shareAction(_:)) , forControlEvents: .TouchUpInside)
