On iOS 26 not able to control size of UITabBar. Sharing code below.
Colour is applying correctly but somehow _UITabBarPlatterView which turns out as TabBar is not extending; leaving spaces on left, right & bottom sides.
class CustomTabBar: UITabBar {
override init(frame: CGRect) {
super.init(frame: frame)
backgroundColor = .red
let firstItem = UITabBarItem(title: "Home", image: UIImage(systemName: "house"), tag: 0)
let secondItem = UITabBarItem(title: "Search", image: UIImage(systemName: "magnifyingglass"), tag: 1)
let thirdItem = UITabBarItem(title: "Profile", image: UIImage(systemName: "person.circle"), tag: 2)
items = [firstItem, secondItem, thirdItem]
selectedItem = firstItem
}
required init?(coder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
}
class ViewController: UIViewController {
let tabBar: CustomTabBar = {
let tb = CustomTabBar()
tb.translatesAutoresizingMaskIntoConstraints = false
return tb
}()
override func viewDidLoad() {
super.viewDidLoad()
view.backgroundColor = .systemBackground
view.addSubview(tabBar)
NSLayoutConstraint.activate([
tabBar.leadingAnchor.constraint(equalTo: view.leadingAnchor, constant: 25),
tabBar.trailingAnchor.constraint(equalTo: view.trailingAnchor, constant: -25),
tabBar.bottomAnchor.constraint(equalTo: view.safeAreaLayoutGuide.bottomAnchor)
])
}
}
when specifying height in CustomTabBar explicitly...
func alignInternalSubViews() {
subviews.forEach { subView in
subView.translatesAutoresizingMaskIntoConstraints = false
NSLayoutConstraint.activate([
subView.topAnchor.constraint(equalTo: topAnchor),
subView.leadingAnchor.constraint(equalTo: leadingAnchor),
subView.trailingAnchor.constraint(equalTo: trailingAnchor),
subView.bottomAnchor.constraint(equalTo: bottomAnchor),
subView.heightAnchor.constraint(equalToConstant: 62)
])
}
}
What should I need to do in order to get this capsule _UITabBarPlatterView and its subviews resize accordingly?
