ios – 无法将值类型’TableViewController.Type’转换为预期的参数类型’UIViewController’

概述我正在制作一个注册并登录的应用程序.我为此使用了Parse.如果登录/注册成功,我想将View Controller移动到TableViewController.但是我收到此错误：“无法将值类型’TableViewController.Type’转换为期望的参数类型’UIViewController’. 这是我收到错误的行： func logInViewController(logInContro 我正在制作一个注册并登录的应用程序.我为此使用了Parse.如果登录/注册成功,我想将VIEw Controller移动到tableVIEwController.但是我收到此错误：“无法将值类型’tableVIEwController.Type’转换为期望的参数类型’UIVIEwController’.

这是我收到错误的行：

func logInVIEwController(logInController: PFLogInVIEwController,dIDLogInUser user: PFUser) {    self.dismissVIEwControllerAnimated(true,completion: nil)    self.presentVIEwController(TimelinetableVIEwController,animated: true,completion: nil)}

这是整个代码：

解决方法 首先,您尝试从登录视图控制器呈现您的新视图控制器即将解散.那是不对的.您可能希望从呈现登录视图控制器的稳定视图控制器呈现它.这是关于如何做到这一点的 nice example.这是基于objective-c所以请耐心等待.

其次,您需要创建一个TimelinetableVIEwController对象以显示在视图层次结构中(再次查看我上面分享的链接).像这样的东西：

let timelinetableVC = TimelinetableVIEwController()self.presentVIEwController(timelinetableVC,completion: nil)
