Status Bar

If you want to have different status bar styles for root, left and right views, then you need to override prefersStatusBarHidden, preferredStatusBarStyle and preferredStatusBarUpdateAnimation in corresponding view controller or instead you can use these properties:

rootViewStatusBarHidden: BOOL
rootViewStatusBarStyle: UIStatusBarStyle
rootViewStatusBarUpdateAnimation: UIStatusBarAnimation

leftViewStatusBarHidden: BOOL
leftViewStatusBarStyle: UIStatusBarStyle
leftViewStatusBarUpdateAnimation: UIStatusBarAnimation

rightViewStatusBarHidden: BOOL
rightViewStatusBarStyle: UIStatusBarStyle
rightViewStatusBarUpdateAnimation: UIStatusBarAnimation

These properties have greater priority than overridden inside controllers prefersStatusBarHidden, preferredStatusBarStyle, preferredStatusBarUpdateAnimation.

For example, you had sideMenuController with rootViewController, leftViewController and rightViewController. For rootViewController, you can override it's default methods or use sideMenuController's properties:

// In RootViewController.swift

override var prefersStatusBarHidden : Bool {
    return false
}

override var preferredStatusBarStyle : UIStatusBarStyle {
    return .default
}

override var preferredStatusBarUpdateAnimation : UIStatusBarAnimation {
    return .none
}

// OR in SideMenuController.swift

isRootViewStatusBarHidden = false
rootViewStatusBarStyle = .default
rootViewStatusBarUpdateAnimation = .none

// OR in SideMenuController.swift

override var isRootViewStatusBarHidden: Bool {
    get { return false }
    set { super.isRootViewStatusBarHidden = newValue }
}

override var rootViewStatusBarStyle: UIStatusBarStyle {
    get { return .default }
    set { super.rootViewStatusBarStyle = newValue }
}

override var rootViewStatusBarUpdateAnimation: UIStatusBarAnimation {
    get { return .none }
    set { super.rootViewStatusBarUpdateAnimation = newValue }
}

For leftViewController and rightViewController approach is the same.
