Corner radius for a navigation bar

Question

i have developed an iPad app. In that app i have 4 separate views embedded inside a single view controller and there is a navigation bar for each view.I want to set the corner radius of each navigation bar.

i tried

       customNavigationBar.layer.cornerRadius = 25;

but this piece of code is not working. Does anyone know how to set the corner radius for each navigation bar.

Answer 1

customNavigationBar.layer.cornerRadius=25;
customNavigationBar.clipsToBounds=YES;

i have tested it successfully

Answer 2

Swift 4: Also if you only want the top edges of the navigation bar to have rounded corners , you can try this

override func viewDidAppear(_ animated: Bool) {
    self.navigationController?.navigationBar.layer.cornerRadius = 20
    self.navigationController?.navigationBar.clipsToBounds = true
    self.navigationController?.navigationBar.layer.maskedCorners = [.layerMinXMinYCorner,.layerMaxXMinYCorner]
}

Answer 3

Add an image with corner rounded as background of navigation bar to make it happen. Check this link Applying rounded corners for the whole application
