Question

使用SWiFT SpriteKit我想删除＆＃39; createLeftButtonFirst＆＃39;和＆＃39; createLeftButtonFirst＆＃39;屏幕上的按钮当按下“按下第一个”按钮时和＆＃39; buttonPressedRightFirst＆＃39;被压了。你有机会帮我这个吗？

以下是代码：

func createLeftButton () {
    let button = UIButton();
    button.frame = CGRectMake(self.frame.width - self.frame.width, 0, self.frame.width / 2, self.frame.height) // X, Y, width, height
    button.backgroundColor = UIColor.greenColor()
    button.addTarget(self, action: "buttonPressedRight:", forControlEvents: .TouchUpInside)
    self.view!.addSubview(button)
    button.layer.zPosition = 0

}

func createRightButton () {

    let buttonRight = UIButton();

    buttonRight.frame = CGRectMake(self.frame.width / 2, 0, self.frame.width / 2, self.frame.height) // X, Y, width, height
    buttonRight.backgroundColor = UIColor.blueColor()
    buttonRight.addTarget(self, action: "buttonPressedLeft:", forControlEvents: .TouchUpInside)
    self.view!.addSubview(buttonRight)
    buttonRight.layer.zPosition = 0

}

func createLeftButtonFirst () {
    let buttonFirst = UIButton();
    buttonFirst.frame = CGRectMake(self.frame.width - self.frame.width, 0, self.frame.width / 2, self.frame.height) // X, Y, width, height
    buttonFirst.backgroundColor = UIColor.grayColor()
    buttonFirst.addTarget(self, action: "buttonPressedRightFirst:", forControlEvents: .TouchUpInside)
    self.view!.addSubview(buttonFirst)
    buttonFirst.layer.zPosition = 1

}

func createRightButtonFirst () {

    let buttonRightFirst = UIButton();

    buttonRightFirst.frame = CGRectMake(self.frame.width / 2, 0, self.frame.width / 2, self.frame.height) // X, Y, width, height
    buttonRightFirst.backgroundColor = UIColor.blackColor()
    buttonRightFirst.addTarget(self, action: "buttonPressedLeftFirst:", forControlEvents: .TouchUpInside)
    self.view!.addSubview(buttonRightFirst)
    buttonRightFirst.layer.zPosition = 1

}


func buttonPressedRight(sender: UIButton!) {


    if buttonPressed == 0 {

    player.physicsBody?.applyImpulse(CGVector(dx: -15, dy: 0))
        buttonPressed = 1


    }

}
func buttonPressedLeft(sender: UIButton!) {
    if buttonPressed == 1 {

    player.physicsBody?.applyImpulse(CGVector(dx: 15, dy: 0))
        buttonPressed = 0

    }
}


/* First Buttons*/
func buttonPressedRightFirst(sender: UIButton!){

    player.physicsBody?.applyImpulse(CGVector(dx: -15, dy: 0))
    buttonPressed = 1




}

func buttonPressedLeftFirst(sender: UIButton!){

    player.physicsBody?.applyImpulse(CGVector(dx: 15, dy: 0))
    buttonPressed = 0
    self.removeFromParent()
}

也许有人会在寻找与我相似的答案，所以我正在发布简单的解决方案-要删除点击的按钮，您应该调用函数：

union

此行应放置在按钮操作目标中：

<div *ngIf= isIdleState" >
<div class="modal-dialog modal-sm" style="display:block;">
  <div class="modal-content">
    <div class="modal-header">
      <h4>Session Timeout warning</h4>
    </div>
    <div class="modal-body">
      you will be timed out in {{countdown}}
    </div>
    <div class="modal-footer">
      <button type="button" class="btn btn-primary" (click)="reset()">Continue</button>
    </div>
  </div>
</div>

Answer 2

按下它们时，只需让它们hidden：

func leftButtonPressed(sender: UIButton!) {
    leftButton.hidden = true
    rightButton.hidden = true
}

func rightButtonPressed(sender: UIButton!) {
    leftButton.hidden = true
    rightButton.hidden = true
}
