我尝试实现左侧面板，但是当我实现时，它似乎除了容器之外不会显示任何内容。
下面是我的代码:
override func viewDidLoad() {
super.viewDidLoad()
initCenter(screen: showVC)
}
func initCenter(screen: ShowWhichVC) {
var presetingController: UIViewController
showVC = screen
if dashboardVC == nil {
dashboardVC = UIStoryboard.dashboardController()
dashboardVC.delegate = self
}
presetingController = dashboardVC
if let con = centerController {
con.view.removeFromSuperview()
con.removeFromParentViewController()
}
centerController = presetingController
view.addSubview(centerController.view)
self.addChildViewController(centerController)
centerController.didMove(toParentViewController: self)
}
private extension UIStoryboard {
class func mainStoryboard() -> UIStoryboard {
return UIStoryboard(name: "Main", bundle: Bundle.main)
}
class func leftPanelController() -> LeftPanelController? {
return mainStoryboard().instantiateViewController(withIdentifier: "LeftPanelController") as? LeftPanelController
}
class func dashboardController() -> DashboardController? {
return mainStoryboard().instantiateViewController(withIdentifier: "DashboardController") as? DashboardController
}
}
注意:DashboardController 和 LeftPanelController UI 是以编程方式编写的，这有什么关系吗？谢谢!

我认为现在它与 GMSMapview 有关
最佳答案
我找到了解决办法!经过彻底检查，我发现 centerController View 大小设置为 0，所以我所做的是为其添加一个绑定(bind)到屏幕的大小尺寸。
centerController.view.frame = CGRect(x: 0, y: 0, width: self.view.bounds.width, height: self.view.bounds.height)
关于ios - UIViewController 容器不显示 ChildViewController，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/51003551/
