以编程方式使用手势将子视图控制器添加到父视图控制器
Add Child View Controllers to parent View Controller with gestures programmatically
我正在尝试以编程方式制作汉堡菜单。到目前为止，我已经成功地构建了一些在使用 UIViews 并将手势附加到它们时有效的东西（减去一些错误）。
现在我想将我的 UIView 换成名为 UIViewController 的 UIViewController：
jobListController // This is the root controller
sideBarController // This is the side bar
如何将我的 UIViewController 添加到我的汉堡包菜单中 class 并应用我创建的在我的 UIView 上运行良好的手势。
我尝试使用 addChildViewController(jobListController) 添加它们，但这似乎不起作用。
我试图将手势识别器添加到我的汉堡菜单中的视图控制器 class 但我收到此错误：
Type 'jobListController' has no member 'addGestureRecognizer'
我意识到这是因为我没有将视图控制器作为 class 的父级，但我只是在尝试。
我这几天一直在扯头发，不知道该怎么做，任何帮助都会很棒！
