IOS设置UIViewController.view.frame = CGCGRect(x : -200. .) 不能点击按钮

我想把几个 UIViewController 放在一起:

leftViewController.view.frame = CGRect(x: -200, y: 0.0, width: size.width/drawerSize, height: size.height)

    // Center Drawer
    centerViewController.view.frame = CGRect(x: leftViewController.view.frame.width, y: 0.0, width: centerWidth, height: size.height)

    // Right Drawer
    rightViewController.view.frame = CGRect(x: centerViewController.view.frame.origin.x + centerViewController.view.frame.size.width, y: 0.0, width: size.width/drawerSize, height: size.height)

在第一行我使用

leftViewController.view.frame = CGRect(x: -200, y....)

它们会正确显示，但我无法单击 leftViewController 上的按钮。

如果

leftViewController.view.frame = CGRect(x: 0.0, y...)

然后可以单击按钮，但这种布局不是我想要的。

它现在的功能如下图所示，我正在尝试将其修改为可以隐藏左右菜单的滑动菜单栏。

当您的 View 在其父 View 之外时，它无法接收任何触摸事件。您应该在 UIView(其父 View ) touchWithEvents 函数中枚举 subview 并使其接收事件。
