Ios 如何使用全局函数以编程方式返回根视图控制器？
我有三个主要的VC（我的帐户，注册，登录）。然后我有一个Swift文件（Manager.Swift），我在其中设置了一个类函数，在注册或登录之后，它将关闭VC 斯威夫特经理Ios 如何使用全局函数以编程方式返回根视图控制器？,ios,swift,swift2,Ios,Swift,Swift2,我有三个主要的VC（我的帐户，注册，登录）。然后我有一个Swift文件（Manager.Swift），我在其中设置了一个类函数，在注册或登录之后，它将关闭VC 斯威夫特经理 class Manager { class func registerUser(vc: UIViewController?, user_email : String, user_password : String){ let myUrl = NSURL(string: hostURL + "userRegist
