【问题描述】：
class PopPop: UIViewController {
var quickVouch = UIView()
@IBAction func closePopPop (sender: UIButton) {
self.view.removeFromSuperview()
}
override func viewDidLoad() {
super.viewDidLoad()
self.view.backgroundColor = UIColor.black.withAlphaComponent(0.2)
quickVouch.frame = CGRect.init(x: 0, y: 0, width: 260, height: 300)
quickVouch.backgroundColor = UIColor.black
quickVouch.center = self.view.center
quickVouch.layer.cornerRadius = 0
quickVouch.layer.shadowOpacity = 0.0
quickVouch.layer.shadowOffset = CGSize(width: 0.0, height: 0.0)
self.view.addSubview(quickVouch)
let btn: UIButton = UIButton(frame: CGRect(x: 100, y: 265, width: 60, height: 30))
btn.backgroundColor = UIColor.black
btn.setTitle("Close", for: .normal)
btn.addTarget(self, action: Selector(("buttonAction:")), for: UIControlEvents.touchUpInside)
btn.setTitleColor(UIColor.lightGray, for: .normal )
btn.titleLabel!.font = UIFont(name: "AvenirNextCondensed-Medium", size: 20)!
quickVouch.addSubview(btn)
}
不知道为什么我会收到此错误。按下按钮时，应用程序崩溃。代码很新，可能在这里遗漏了一些东西....
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)
}
这是来自主 ViewController 的代码。
【问题讨论】：
-
无法识别的选择器叫什么名字？
-
这是说 PopPop 按钮动作。
-
您的代码中是否有一个名为“PopPop”的方法？您是否将“PopPop”重命名为“closePopPop”并且没有重新连接笔尖中的插座？
