我正在尝试以编程方式在我的应用程序中实现侧边菜单。所以我设计了一个视图控制器，它的一半视图作为表格视图。设计和编码已经完成，现在我希望将此视图控制器用作侧边菜单控制器。我的 SideMenu 故事板是：
现在我的代码如下所示：
import UIKit
class SideBarViewController: UIViewController {
@IBOutlet weak var menu: UIView!
@IBOutlet weak var menuTableView: UITableView!
var fieldImages = [UIImage]()
var isFirstSectionHidden: Bool = true
var isSecondSectionHidden: Bool = true
var selectedIndex: Int = 0
var menuTag: Int = 0
var name = ""
var email = ""
var imageURL = ""
var language = "English"
var accountNames: [String] = ["My Subscriptions", "My Proposals","My Interests"]
var languageNames: [String] = ["English", "Arabic", "Malayalam"]
override func viewDidLoad() {
super.viewDidLoad()
selectedIndex = -1
self.menu.isHidden = true
menuTag = 0
// self.profile()
let swipeRight = UISwipeGestureRecognizer(target: self, action: #selector(self.respondToSwipeGesture))
swipeRight.direction = UISwipeGestureRecognizerDirection.right
self.view.addGestureRecognizer(swipeRight)
let swipeLeft = UISwipeGestureRecognizer(target: self, action: #selector(self.respondToSwipeGesture))
swipeLeft.direction = UISwipeGestureRecognizerDirection.left
self.view.addGestureRecognizer(swipeLeft)
self.fieldImages.append(UIImage(named: "my_subscription_icon")!)
self.fieldImages.append(UIImage(named: "my_proposal_icon")!)
self.fieldImages.append(UIImage(named: "my_interest_icon")!)
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
func respondToSwipeGesture(gesture: UIGestureRecognizer) {
if let swipeGesture = gesture as? UISwipeGestureRecognizer {
switch swipeGesture.direction {
case UISwipeGestureRecognizerDirection.right:
menuAction()
print("Swiped right")
case UISwipeGestureRecognizerDirection.left:
menuAction()
print("Swiped left")
default:
break
}
}
}
func menuAction() {
if menuTag == 0 {
UIView.animate(withDuration: 0.5, animations: {() -> Void in
self.menu.frame = CGRect(x: 0, y: 0, width: self.menu.frame.size.width, height: self.menu.frame.size.height)
self.menu.isHidden = false
self.menuTag = 1
self.menuTableView.reloadData()
})
}
else {
UIView.animate(withDuration: 0.5, animations: {() -> Void in
self.menu.frame = CGRect(x: -self.menu.frame.size.width, y: 0, width: self.menu.frame.size.width, height: self.menu.frame.size.height)
self.menu.isHidden = true
self.menuTag = 0
self.menuTableView.reloadData()
})
selectedIndex = -1
}
}
func profile() {
if Utility.isConnectedToInternet {
Utility.startActivityIdicator()
VanpoolAPI.profile { (response) in
Utility.stopActivityIndicator()
if response == nil {
Utility.showAlert(title: Constants.error, message: Constants.someThingWrong, delegate: self)
} else {

self.name = (response?.name)!
self.email = (response?.email)!
self.imageURL = (response?.displayPictureUrl)!
} else {
Utility.showAlert(title:Constants.appName, message:response?.message?.key ?? "", delegate: self)
}
}
}
} else {
Utility.showAlert(title: Constants.appName, message: Constants.noNetwork, delegate: self)
}
}
func logout() {

知道如何以编程方式将此视图控制器作为我的侧视图控制器。请注意，我尽量避免使用第三方课程。
