Question

我在我的场景/视图中设置了一个UIButton，按钮显示了ViewController调用场景的时间。问题是当我点击Button并调用我的GameScene时，Button仍然存在。我想我以错误的方式设置了按钮我想问题是，我无法在startGame函数中的button1上调用import Foundation import SpriteKit import UIKit class MenuScene: SKScene { override init(size: CGSize) { super.init(size: size) backgroundColor = SKColor.grayColor() let label = SKLabelNode(fontNamed: "CourierNewPS-BoldMT") label.text = "Start Game" label.fontSize = 40 label.fontColor = SKColor.blackColor() label.position = CGPoint(x: size.width/2, y: size.height/2) addChild(label) } override func didMoveToView(view: SKView) { let button1=UIButton(frame: CGRectMake(size.width/2, size.height/2, 300, 100)) button1.backgroundColor = UIColor.greenColor() button1.setTitleColor(UIColor.blackColor(), forState: .Normal) button1.setTitle("Unfocused", forState: .Normal) button1.setTitle("Start", forState: .Focused) button1.addTarget(self, action: "startGame:", forControlEvents: UIControlEvents.PrimaryActionTriggered) self.view?.addSubview(button1) } func startGame(sender:UIButton) { let gameView = view! as SKView gameView.ignoresSiblingOrder = true let reveal = SKTransition.flipHorizontalWithDuration(0.2) let scene = GameScene(size: self.size) gameView.presentScene(scene, transition:reveal) } required init(coder aDecoder: NSCoder) { fatalError("init(coder:) has not been implemented") } }函数。

我该如何解决这个问题？任何帮助表示赞赏！

#include <stdio.h>
int main()
{
  int N, a, divide, flag=0;
 printf("Please enter a positive integer ");
   scanf("%d",&N);
   if (N<2||N>1000000)
  {
    printf("Error!");
    return 0;
  }
  for(a=2;a<=N/2;++a)
 {
  if(N%a==0)
  {
      flag=1;
      break;
  }
 }
 if (flag==0)
  printf("The number %d is a prime number.", N);
 else
  {
     printf("The number %d is not a prime number.\nThe prime factors of %d are:",N, N);

divide = 2;

 while(N!=0&&flag==1){
    if(N%divide!=0)
        divide = divide + 1;
    else {
        N = N / divide;
        printf("%d",divide);
        if(N==1)
            break;
        }
    }
 }

  return 0;
}

您可以使用<String, Void, String>方法button1访问sender个对象。在这种情况下，它是startGame(sender:UIButton)的引用。你可以从中调用button1方法：

removeFromSuperview
