如何使用一个UIButton隐藏和取消隐藏图像.迅速

Question

我想隐藏这些图像并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
}

你应该使用!在实际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
}
