ios - 在 Swift 3 中更改状态栏背景颜色

Question

在 XCode 7.3.x 中，我更改了 StatusBar 的背景颜色:

func setStatusBarBackgroundColor(color: UIColor) {
guard  let statusBar = UIApplication.sharedApplication().valueForKey("statusBarWindow")?.valueForKey("statusBar") as? UIView else {
    return
}
statusBar.backgroundColor = color
}

但它似乎不再适用于 Swift 3.0。

我会尝试:

func setStatusBarBackgroundColor(color: UIColor) {
guard  let statusBar = (UIApplication.shared.value(forKey: "statusBarWindow") as AnyObject).value(forKey: "statusBar") as? UIView else {
    return
}
statusBar.backgroundColor = color
}

但它给了我:

this class is not key value coding-compliant for the key statusBar.

关于如何用 XCode8/Swift 3.0 改变它有什么想法吗？

Answer 1

extension UIApplication {
    var statusBarView: UIView? {
        if responds(to: Selector(("statusBar"))) {
            return value(forKey: "statusBar") as? UIView
        }
        return nil
    }
}

UIApplication.shared.statusBarView?.backgroundColor = .red

iOS 13 更新

App called -statusBar or -statusBarWindow on UIApplication: this code must be changed as there's no longer a status bar or status bar window. Use the statusBarManager object on the window scene instead.
