Swift custom UIView IBOutlet nil , awakeFromNib() never called - ios

Question

I am trying to custom a UIView but when I call it, the outlets of custom view always nil, and awakeFromNib() never called, too. Here my CustomView:
class DropdownMenuView: UIView {
//MARK: Outlets
#IBOutlet var view: DropdownMenuView!
#IBOutlet weak var fadeView: UIView!
#IBOutlet weak var tableView: UITableView!
var selection:Selection = .Default
var iconType:IconType = .Default
var menuTitles:[String] = []
var cellHeight:CGFloat = 44
var textColorNomal:UIColor = UIColor.blackColor()
var textColorHighlight:UIColor = UIColor.redColor()
var isShown: Bool!
//MARK: Lifecycle
override func awakeFromNib() {
print("awakeFromNib")
super.awakeFromNib()
initSubviews()
configView()
}
override func layoutSubviews() {
super.layoutSubviews()
}
override init(frame: CGRect) {
super.init(frame: frame)
}
required init(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)!
}
func initSubviews() {
if let nibsView = NSBundle.mainBundle().loadNibNamed("DropdownMenuView", owner: self, options: nil) as? [UIView] {
let nibRoot = nibsView[0]
self.addSubview(nibRoot)
nibRoot.frame = self.bounds
}
}
required init(uSelection: Selection = Selection.Default, uIconType:IconType = IconType.Default, uMenuTitles:[String]) {
self.selection = uSelection
self.iconType = uIconType
self.menuTitles = uMenuTitles
super.init(frame: CGRect(x: 0, y: 0, width: 0, height: 0))
}
private func configView() {
switch (selection) {
case Selection.Multiple:
tableView.allowsMultipleSelection = true
default:
tableView.allowsMultipleSelection = false
}
tableView.registerNib(UINib(nibName: "DropdownMenuCell", bundle: nil), forCellReuseIdentifier: "DropdownMenuCell")
}
override func touchesEnded(touches: Set<UITouch>, withEvent event: UIEvent?) {
hideMenu()
}
internal func show() {
if self.isShown == false {
self.showMenu()
}
}
internal func hide() {
if self.isShown == true {
self.hideMenu()
}
}
func showMenu() {
self.isShown = true
if let app = UIApplication.sharedApplication().delegate as? AppDelegate, let window = app.window {
window.bringSubviewToFront(self)
}
// Animation
UIView.animateWithDuration(0.3, animations: { () -> Void in
self.alpha = 1
})
}
func hideMenu() {
self.isShown = false
// Animation
UIView.animateWithDuration(0.3, animations: { () -> Void in
self.alpha = 0
})
}
}
//MARK: UITableViewDelegate methods
extension DropdownMenuView: UITableViewDelegate {
func tableView(tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
return CGFloat(menuTitles.count) * cellHeight
}
func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {
return cellHeight
}
func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCellWithIdentifier("DropdownMenuCell") as! DropdownMenuCell
cell.lblTitle.text = menuTitles[indexPath.row]
cell.iconType = iconType
return cell
}
}
//MARK: UITableViewDataSource methods
extension DropdownMenuView: UITableViewDataSource {
func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return menuTitles.count
}
}
I tried to remove outlets and connect again, but I wasn't lucky. It isn't working anymore. You can check my full demo project here:

You click on "Label" on StartVC to call custom UIView.
I hope what I ask is possible. Any helps always are appropriate!
