ios - 无法检测到 ScrollView 中的 Swift UI 组件

Question

我在 ScrollView 中有一个 UIView。但是这个 UIVIew 中的每个组件甚至它本身都无法检测到手势。

我必须使用文本字段输入昵称，还必须点击 UIView 以启用/禁用男性/女性性别状态。

这是我的代码。即使我尝试了在 Internet 上找到的其他解决方案，它仍然无法正常工作。

let tapViewMale = UITapGestureRecognizer()
    tapViewMale.addTarget(self, action:#selector(viewMaleClicked))
    self.viewMain!.addGestureRecognizer(tapViewMale)
    let tapViewFemale = UITapGestureRecognizer()#imageLiteral(resourceName: "Screen Shot 2017-11-09 at 12.15.55 PM.png")
    tapViewFemale.addTarget(self, action:#selector(viewFemaleClicked(_:)))
    self.checkboxFemale.isUserInteractionEnabled = true
    self.checkboxFemale.addGestureRecognizer(tapViewFemale)
}

@objc func viewMaleClicked(tapGestureRecognizer: UITapGestureRecognizer) {
    print ("viewMaleClicked")
    if gender == "" || gender == "F" {
        print ("1")
        checkboxMale.image = UIImage(named: "checked_checkbox")
        checkboxFemale.image = UIImage(named: "unchecked_checkbox")
        gender = "M"
    } else {
        print ("2")
        checkboxMale.image = UIImage(named: "unchecked_checkbox")
        gender = ""
    }
}

@objc func viewFemaleClicked(_ sender:AnyObject) {
    print ("viewFemaleClicked")
    if gender == "" || gender == "M" {
        print ("1")
        checkboxFemale.image = UIImage(named: "checked_checkbox")
        checkboxMale.image = UIImage(named: "unchecked_checkbox")
        gender = "F"
    } else {
        print ("2")
        checkboxFemale.image = UIImage(named: "unchecked_checkbox")
        gender = ""
    }
}

我认为使用透明按钮而不是在 scrollView 中向 uiview 提供手势的简单方法。

@IBAction func onClickBtnMale(_ sender: Any)
    { if gender == "" || gender == "F" {
        print ("1")
        checkboxMale.image = UIImage(named: "checked_checkbox")
        checkboxFemale.image = UIImage(named: "unchecked_checkbox")
        gender = "M"
    } else {
        print ("2")
        checkboxMale.image = UIImage(named: "unchecked_checkbox")
        gender = ""
    }
}

• 您可以使 uibutton 的宽度与您的 View 相等，并将其用于点击。
