不确定我为什么会收到此错误。按下按钮时,应用程序崩溃。代码很新,可能会遗漏一些东西......
func mapView(_ mapView: GMSMapView, didTapInfoWindowOf marker: GMSMarker) {
let PopOverViewController = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "PopPopID") as! PopPop
self.addChildViewController(PopOverViewController)
PopOverViewController.view.frame = CGRect(x: 0, y: -70, width: 1000, height: 1000)
self.view.addSubview(PopOverViewController.view)
PopOverViewController.didMove(toParentViewController: self)
}
这是主ViewController的代码。
答案 0 :(得分:0)
我改变了这行代码,现在一切都按计划进行了!
btn.addTarget(self, action: #selector(PopPop.buttonAction(_:)), for: UIControlEvents.touchUpInside)
