UITabBar on top or any other?

Question

I'm new to swift, going to create an UI in that a tabor is being shown in it , As i gone through the apple's human interface guidelines , they said not use UITabBar on top. We can use it by custom , but many of them said while submitting in App Store it will get rejected.

So instead of UITabar what should use for the tab on top?

Answer 1

You should use a segmented control in the navigation bar, as in this example form the iOS Human Interface Guidelines:

Answer 2

Is it possible? Sure, but it violates the human interface guidelines.

Swift Version

import UIKit

class TabViewController: UITabBarController, UITabBarControllerDelegate {

override func viewDidLoad() {
  super.viewDidLoad()
  self.delegate = self
  // Do any additional setup after loading the view.
}
override func viewWillLayoutSubviews() {
 super.viewWillLayoutSubviews()
 self.tabBar.invalidateIntrinsicContentSize()
 var tabSize: CGFloat = 44.0
 let orientation = UIApplication.sharedApplication().statusBarOrientation
 if UIInterfaceOrientationIsLandscape(orientation)
 {
    tabSize = 32.0;
 }
 var tabFrame = self.tabBar.frame
 tabFrame.size.height = tabSize
 tabFrame.origin.y = self.view.frame.origin.y
 self.tabBar.frame = tabFrame
 self.tabBar.translucent = false
 self.tabBar.translucent = true
}
