我正在尝试以编程方式制作汉堡包菜单。到目前为止，我已经设法在使用UIViews并将手势附加到它们时构建一些有效（减去一些错误）的东西。
现在我想将UIViews换成名为的
的UIViewControllersjobListController // This is the root controller
sideBarController // This is the side bar
如何将我的UIViewControllers添加到我的汉堡菜单类中，并应用我创建的手势，这些手势似乎在我的UIViews上正常工作。
我尝试使用addChildViewController(jobListController)添加它们，但这似乎不起作用。
我尝试将手势识别器添加到我的汉堡菜单类中的viewcontrollers但是我收到此错误：
输入＆＃39; jobListController＆＃39;没有会员＆＃39; addGestureRecognizer＆＃39;
我意识到这是因为我没有将视图控制器教给班级，但我只是在尝试。
我已经把头发撕了几天了，不知道怎么做，任何帮助都会很棒！
这是我的汉堡包菜单代码（我已经离开了UIViews，所以你可以看到我想要做的事情：

我的2个控制器的代码，代码完全相同，除了我上面提到的类名：
class sideBarController：UIViewController {
let screenHeight = UIScreen.main.bounds.height
let screenWidth = UIScreen.main.bounds.width
var greyBackground: UIView! = {
let greyBackground = UIView()
greyBackground.backgroundColor = UIColor(red:0.18, green:0.20, blue:0.21, alpha:1.0)
greyBackground.translatesAutoresizingMaskIntoConstraints = false
return greyBackground
}()
override func viewDidLoad() {
super.viewDidLoad()
view.addSubview(greyBackground)
setupLayout()
}
private func setupLayout(){
greyBackground.rightAnchor.constraint(equalTo: view.leftAnchor, constant: 0).isActive = true
greyBackground.centerYAnchor.constraint(equalTo: view.centerYAnchor).isActive = true
greyBackground.heightAnchor.constraint(equalToConstant: screenHeight).isActive = true
greyBackground.widthAnchor.constraint(equalToConstant: screenWidth).isActive = true
}
}
答案 0 :(得分：1)
我假设jobListController是一个UIViewController？您需要在其视图中添加手势识别器（jobListController.view）。不确定这是否是您遇到的唯一问题，但这将解决崩溃问题。
