}

override func viewDidLoad() {
    super.viewDidLoad()

    viewControllers = [

    return settingBarButtonItem
}

@objc func btnMenuAction() {

    blackScreen.isHidden = false
    UIView.animate(withDuration: 0.3, animations: {
        self.sidebarView.frame=CGRect(x: 0, y: 0, width: 250, height: self.sidebarView.frame.height)
    }) { (complete) in
        self.blackScreen.frame=CGRect(x: self.sidebarView.frame.width, y: 0, width: self.view.frame.width-self.sidebarView.frame.width, height: self.view.bounds.height+100)
    }
}

    }
}



// sideMenu


class SidebarView: UIView, UITableViewDelegate, UITableViewDataSource {

    return btnClose
}()

func show() {
    testContainer.addSubview(btnClose)

    if let window = UIApplication.shared.keyWindow {
        window.addSubview(testContainer)

        setUpTestContainer()

        UIView.animate(withDuration: 0.5, delay:0, usingSpringWithDamping: 1, initialSpringVelocity:1, options: .curveEaseOut, animations: {

            self.testContainer.frame = CGRect(x: 0, y: 0, width: (self.frame?.width)!, height: (self.frame?.height)!)

        }, completion: nil)
    }
}


func setUpTestContainer(){
    testContainer.frame = CGRect(x: 0, y: (self.frame?.height)!, width: (self.frame?.width)!, height: (self.frame?.height)!)
}

@objc func handleDismiss() {
    UIView.animate(withDuration: 0.2, animations: {
        if let window = UIApplication.shared.keyWindow{
            self.testContainer.frame = CGRect(x: 0, y: window.frame.height, width:
                self.testContainer.frame.width, height: self.testContainer.frame.height)
        }
    }, completion: {(finished:Bool) in
        self.testContainer.removeFromSuperview()
    })
}

override init() {
    super.init()

}
}

how can I remove last uiview? I'm newbie. Please help me. Thank in advanced

why did you use a NSObject Class **TestLauncher** you can directly use a **ViewController** — iOS Geek, Jun 25 '18 at 04:57

need some modifications here

extension TabBarCtr: SidebarViewDelegate {
    func sidebarDidSelectRow(row: Row) {
        blackScreen.isHidden=true
        blackScreen.frame=self.view.bounds
        UIView.animate(withDuration: 0.3) {
            self.sidebarView.frame=CGRect(x: 0, y: 0, width: 0, height: self.sidebarView.frame.height)
        }
        switch row {
        case .Name:
            print(" Name ")
        case .test:
            let test = TestLauncher()
            /// Comment below line
            test.show()

            /// Simply  Present it
            self.present(test, animated: true, completion: nil)
        case .test1:
            print("test1")
        case .none:
            break
        }
    }
}

Now in your TestLauncher

change

class TestLauncher: NSObject

to

class TestLauncher: UIViewController

Add View Life Cycles and to retain your animation

override func viewDidAppear(_ animated: Bool) {
    self.view.backgroundColor = .white
    self.testContainer.frame = CGRect(x: 0, y: self.view.frame.size.height, width: self.view.frame.size.width, height: self.view.frame.size.height)
    self.view.addSubview(self.testContainer)
    self.testContainer.addSubview(self.btnClose)
    UIView.animate(withDuration: 0.5, delay:0, usingSpringWithDamping: 1, initialSpringVelocity:1, options: .curveEaseOut, animations: {
        self.testContainer.frame = CGRect(x: 0, y: 0, width: self.view.frame.size.width, height: self.view.frame.size.height)

    }, completion: nil)
}

Button Action

@objc func handleDismiss1(_ sender: UIButton) {
    self.dismiss(animated: true, completion: nil)
}

Thank you so much. Love you. – Thái An Nguyễn Jun 25 '18 at 06:00 — Thái An Nguyễn, Jun 25 '18 at 06:00
