Question

我想要隐藏这些图片并使用相同的按钮取消隐藏它们。现在我有一个按钮连接2个动作。触摸向下和触摸向下重复。触摸向下重复按下按钮两次以取消隐藏图像。我只想按下它一次取消隐藏，就像我按下隐藏时一样。任何人都知道如何处理这个问题？

@IBAction func settingsCheck(sender: UIButton) {
    c.hidden = true
    d.hidden = true
    e.hidden = true
    f.hidden = true
    g.hidden = true
    a.hidden = true
    b.hidden = true
    cFour.hidden = true
    settingsCheck.hidden = false
}

@IBAction func settingCheckButtonsUnhide(sender: UIButton) {
    c.hidden = false
    d.hidden = false
    e.hidden = false
    f.hidden = false
    g.hidden = false
    a.hidden = false
    b.hidden = false
    cFour.hidden = false
    settingsCheck.hidden = true
}

Answer 1

你应该使用！在实际的隐藏状态前面如下反转它：

@IBAction func settingsCheck(sender: UIButton) {
     c.hidden = !c.hidden
     d.hidden = !d.hidden
     e.hidden = !e.hidden
     f.hidden = !f.hidden
     g.hidden = !g.hidden
     a.hidden = !a.hidden
     b.hidden = !b.hidden
     cFour.hidden = !cFour.hidden
}

Answer 2

正如@matt在评论中建议的那样，你可以使用：

@IBAction func settingsCheck(sender: UIButton) {

if c.hidden == false {
 c.hidden = true
 d.hidden = true
 e.hidden = true
 f.hidden = true
 g.hidden = true
 a.hidden = true
 b.hidden = true
 cFour.hidden = true}

else {
c.hidden = false
d.hidden = false
e.hidden = false
f.hidden = false
g.hidden = false
a.hidden = false
b.hidden = false
cFour.hidden = false
  }
}
