swift – 禁用UIButton无法正常工作

所以我正在尝试在某个条件满足(或不满足)的情况下禁用按钮的功能/可点击性.所以在它之前,如果条件不满足则禁用所有条件,然后如果在(动态)它满足之后,它理论上应该启用.话虽这么说,当我开始使用.isEnabled = false时,它最初不会禁用按钮.

我知道这个条件正在得到满足,因为@L_675_3@打印语句和其他测试(比如标签被删除了fromuperview还是.isEnabled = false因为按钮不起作用.有人遇到过这些问题或有任何解决方案吗？

代码如下：

override func viewDidLoad()
{
    super.viewDidLoad()
    trumpMoneyDefault.SETVALue(50,forKey: "TrumpMoney")
    print("UnoViewController")
    //make all the buttons that shouldn't be clickable unlcickable
    locklvl2.isEnabled = false
    locklvl3.isEnabled = false
    trumplvl2.isEnabled = false
    trumplvl3.isEnabled = false
    lvl2.isEnabled = false
    lvl3.isEnabled = false

    //make level2/3 unclickable by defeault
    //lvl2.isEnabled = false
    //lvl3.isEnabled = false
    //update trumpmoney label depending on if they have enough cash
    //also here check if they have already unlocked all via purchase of unlock all. If so,then skip all this
    if trumpMoneyDefault.value(forKey: "TrumpMoney") != nil
    {
        trumpmoney.text = trumpMoneyDefault.value(forKey: "TrumpMoney") as? String

        //remove locks if they got the money by default.
        let tempTrumpMoneyDefault = trumpMoneyDefault.value(forKey: "TrumpMoney") as! Int
        if tempTrumpMoneyDefault >=  100
        {
            locklvl2.removeFromSuperview()
            moneylvl2.removeFromSuperview()
            trumplvl2.removeFromSuperview()
            lvl2.isEnabled = true
            if tempTrumpMoneyDefault >=  500
            {
                locklvl3.removeFromSuperview()
                moneylvl3.removeFromSuperview()
                trumplvl3.removeFromSuperview()
                lvl3.isEnabled = true
            }
        }
    }
}
