custom header UIView to all the VC?

Question

I am trying to create a custom header file to all the ViewControllers in project. The following image is an actual design.

So that I am trying to create Custom view with Xib file as below :

import UIKit

class HamburgrView: UIView {
    override init(frame: CGRect) {
        // 1. setup any properties here
        // 2. call super.init(frame:)
        super.init(frame: frame)
        // 3. Setup view from .xib file
        xibSetup()
    }
    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
        xibSetup()
    }
    override open func prepareForInterfaceBuilder() {
        super.prepareForInterfaceBuilder()
        xibSetup()
    }
    override func layoutSubviews() {

    }
    func xibSetup() {

       let  tempView = loadViewFromNib()
        // use bounds not frame or it'll be offset
        tempView.frame = bounds
        // Make the view stretch with containing view
        tempView.autoresizingMask = [.flexibleWidth, .flexibleHeight]
        // Adding custom subview on top of our view (over any custom drawing > see note below)
        addSubview(tempView)

    }

    func loadViewFromNib() -> UIView {
        let bundle = Bundle(for: type(of:self))
        let nib = UINib(nibName: "HamburgrView", bundle: bundle)

        // Assumes UIView is top level and only object in CustomView.xib file
        let view = nib.instantiate(withOwner: self, options: nil)[0] as! UIView
        return view
    }


}

We don't know how to draw that Hamburger menu icon with curve and its start position from SafeArealayoutGuide.

I trying one view with x position negative -40 and giving cornerRadius not coming perfect curve like above image.

Output look not good.

My ViewController Code :

override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view.

        let hamView = HamburgrView(frame: .zero)
        self.view.addSubview(hamView)
        hamView.translatesAutoresizingMaskIntoConstraints = false
        NSLayoutConstraint.activate([
            hamView.topAnchor.constraint(equalTo: self.view.safeAreaLayoutGuide.topAnchor, constant: 0),
            hamView.leadingAnchor.constraint(equalTo: self.view.leadingAnchor, constant: 0),
            hamView.widthAnchor.constraint(equalToConstant: 120),
            hamView.heightAnchor.constraint(equalToConstant:  80)
            ])
    }

As @sandip answer I have changed like below :

func xibSetup() {

       let  tempView = loadViewFromNib()
        // use bounds not frame or it'll be offset
        tempView.frame = bounds
        // Make the view stretch with containing view
        tempView.autoresizingMask = [.flexibleWidth, .flexibleHeight]
        // Adding custom subview on top of our view (over any custom drawing > see note below)
        addSubview(tempView)
        let layer = CAShapeLayer()
        layer.path = UIBezierPath.init(arcCenter: CGPoint(x: 0, y: self.center.y), radius: 50, startAngle: -1.5708, endAngle: 1.5708, clockwise: true).cgPath
        layer.fillColor = UIColor.red.cgColor
        self.layer.addSublayer(layer)
    }

Output Looks Below :

Any idea would be appreciate.

Answer 1

Is this what you wanted?

You can easily achieve it with CAShapeLayer and UIBezierPath

    let layer = CAShapeLayer()
    layer.path = UIBezierPath.init(arcCenter: CGPoint(x: 0, y: self.view.center.y), radius: 30, startAngle: -1.5708, endAngle: 1.5708, clockwise: true).cgPath
    layer.fillColor = UIColor.red.cgColor
    view.layer.addSublayer(layer)

In your code change arc centre as x to be zero and y to hamburger view's vertical centre and add it to self.view

Hope it helps

EDIT 1:

As OP has asked for complete code in comment updating the answer

class HamburgrView: UIView {
    override init(frame: CGRect) {
        // 1. setup any properties here
        // 2. call super.init(frame:)
        super.init(frame: frame)
        // 3. Setup view from .xib file
        xibSetup()
    }
    required init?(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
        xibSetup()
    }
    override open func prepareForInterfaceBuilder() {
        super.prepareForInterfaceBuilder()
        xibSetup()
    }
    override func layoutSubviews() {

    }
    func xibSetup() {

       let  tempView = loadViewFromNib()
        // use bounds not frame or it'll be offset
        tempView.frame = bounds
        // Make the view stretch with containing view
        tempView.autoresizingMask = [.flexibleWidth, .flexibleHeight]
        // Adding custom subview on top of our view (over any custom drawing > see note below)
        addSubview(tempView)

    }

    func loadViewFromNib() -> UIView {
        let bundle = Bundle(for: type(of:self))
        let nib = UINib(nibName: "HamburgrView", bundle: bundle)

        // Assumes UIView is top level and only object in CustomView.xib file
        let view = nib.instantiate(withOwner: self, options: nil)[0] as! UIView
        return view
    }

    override func didMoveToSuperview() {
        super.didMoveToSuperview()
        let layer = CAShapeLayer()
        layer.path = UIBezierPath.init(arcCenter: CGPoint(x: 0, y: 40), radius: 50, startAngle: -1.5708, endAngle: 1.5708, clockwise: true).cgPath
        layer.fillColor = UIColor.red.cgColor
        self.layer.addSublayer(layer)
    }
}

EDIT 2:

Reason OPs arc coming outside hamburger view is because of wrong arc centre

changing to CGPoint(x: 0, y: 40) from self.view.center.y should solve the issue. Updated the code to reflect the same

Why 40?

Because OP is setting height of hamburger view to 80. So 80/2 = 40

Why cant we use bounds.size.height / 2 or self.view.center.y?

because in didMoveToSuperview OP's constraint has not kicked in yet so it is taking the height view in xib which I don't think is 80 so it sets the arc centre with that value but then your constraint changes height to 80.

Here is final O/P:
