UITabBar在頂部還是其他？

Question

我是新來的swift，打算創建一個UI，其中顯示了一個tabor，當我通過蘋果的人機界面指南時，他們表示不會在頂部使用UITabBar。我們可以通過自定義來使用它，但是很多人說在App Store中提交時會被拒絕。

因此，而不是UITabar頂部的標籤應該使用什麼？

Answer 1

你應該在這個例子中使用導航欄分段控制，形成了iOS人機界面指南：

Answer 2

這可能嗎？當然，但它違反了人機界面指南。

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 
}
