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。
完整代码由@Kevin Scardina Slide Sidebar Menu IOS 8 Swift 发布
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。
/*
To use simply instantiate NVMDrawerController as your root view in your AppDelegate, or in the
StoryBoard.
Once NVMDrawerController is instantiated, set the drawerSize of the NVMDrawerController,
and its leftViewControllerIdentifier, centerViewControllerIdentifier, and
rightViewControllerIdentifier to the Storyboard Identifier of the UIViewController
you want in the different locations.

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。
关于IOS设置UIViewController.view.frame = CGCGRect(x : -200. .) 不能点击按钮，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/35100177/
