pushViewController 在 swift 3 中不起作用

Question

我添加按钮以通过此代码查看：

btnMarkerInfo.setImage(imgInfo, for: .normal)
btnMarkerInfo.setTitleColor(UIColor.white, for: .normal)
btnMarkerInfo.frame = CGRect(x: w, y: UIScreen.main.bounds.height-70-56, width: 56, height: 56)
btnMarkerInfo.addTarget(self, action: #selector(vcMain.markerDidTap(_:)), for: .touchUpInside)
btnMarkerInfo.isHidden = true
btnMarkerInfo.alpha = 0
self.view.addSubview(btnMarkerInfo)

markerDidTap() 在这里：

func markerDidTap(_ sender: UIButton){
    let vcPointTitles = storyboard?.instantiateViewController(withIdentifier: "vcPointTitles") as! vcPointTitles
    vcPointTitles.pointId = sender.tag
    self.navigationController?.pushViewController(vcPointTitles, animated: false)
}

当用户点击此按钮功能 markerDidTap 运行和 vcPointTitles 时必须显示，功能执行但 vcPointTitles 不显示。 class 和 storyBoardId 设置如下： vcPointTitles 定义如下：

class vcPointTitles: UIViewController, UITableViewDelegate, UITableViewDataSource { .... }

我该如何解决这个问题？

试试这个，虽然来晚了，但对其他面临这种情况的人有帮助

func markerDidTap(_ sender: UIButton){
   let storyBoard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
   let vcPointTitles = 
       storyBoard.instantiateViewController(withIdentifier: "vcPointTitles") as! 
       VCPointTitlesViewController
    vcPointTitles.pointId = sender.tag

   self.present(vcPointTitles, animated: true, completion: nil)
}
