pushViewController在迅速3

Question

不行我添加按钮，通过这个代码查看：

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（）是在这里：

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

时，这个按钮的功能markerDidTap运行和vcPointTitles必须的用户水龙头显示，功能执行但vcPointTitles不显示。 类和storyBoardId设置类似如下： vcPointTitles如下定义：

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

我怎样才能解决这一问题？

试试这个，但它的到来晚了，但是这可能是帮助他人面对这样

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) 
}
