问题描述

我想在app delegate中设置rootViewController ..

  func application（application：UIApplication，didFinishLaunchingWithOptions launchOptions：NSDictionary ？） - > Bool {
 
 var rootView：MyRootViewController = MyRootViewController（）
 //将viewController设置为根视图的代码?? 
 
 
返回true 
 
}

  func application（application：UIApplication， didFinishLaunchingWithOptions launchOptions：NSDictionary？） - > Bool {
 
 var rootView：MyRootViewController = MyRootViewController（）
 
 if let window = self.window {
 window.rootViewController = rootView 
} 
 
返回true 
}

I want to set the rootViewController in the app delegate ..

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: NSDictionary?) -> Bool {

     var rootView: MyRootViewController = MyRootViewController()
     //Code to set this viewController as the root view??


     return true

}

解决方案

You can do something like this.

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: NSDictionary?) -> Bool {

     var rootView: MyRootViewController = MyRootViewController()

     if let window = self.window{
            window.rootViewController = rootView
     }

     return true
}
