简易代码
class PreferencesTabBar: UITabBar {
override func drawRect(rect: CGRect) {
super.drawRect(rect)
self.backgroundColor = UIColor(red: 166.0/255.0, green: 142.0/255.0, blue: 83.0/255.0, alpha: 0.5)
}
}
我将IB中的UITabBar类设置为我的自定义类,但背景并不是我想要的颜色,而是变得完全透明,就像没有UITabBar一样所有(当然除了UITabBarItems,我仍然可以看到它们)

一种解决方案是通过从标签栏创建@IBOutlet
(按住Ctrl键拖动),从包含标签栏的视图控制器设置标签栏的背景。
// ViewController.swift
class ViewController: UIViewController {
@IBOutlet weak var myTabBar: UITabBar!
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
myTabBar.backgroundColor = UIColor(red: 166.0/255.0, green: 142.0/255.0, blue: 83.0/255.0, alpha: 0.5)
}
// ...
}
