AppDelegate 實(shí)現(xiàn)下面的代理方法，并且判斷對(duì)應(yīng)的旋轉(zhuǎn)方向

    static var isPortrait = true
    func application(_ application: UIApplication, supportedInterfaceOrientationsFor window: UIWindow?) -> UIInterfaceOrientationMask {
        return AppDelegate.isPortrait ? .portrait : .landscapeLeft
    }

需要旋轉(zhuǎn)的 controller 重寫(xiě)下面兩個(gè)屬性，例子中是強(qiáng)制向左旋轉(zhuǎn)

class XXViewController: UIViewController {
    override var shouldAutorotate: Bool {
        true
    }

    override var supportedInterfaceOrientations: UIInterfaceOrientationMask {
        .landscapeLeft
    }
}

iOS 16 之前的版本，需要手動(dòng)調(diào)用 setOrientation 方法。

向左旋轉(zhuǎn)

        AppDelegate.isPortrait = false
        if #unavailable(iOS 16) {
            let value = UIInterfaceOrientation.landscapeLeft.rawValue
            if UIDevice.current.responds(to: #selector(setValue(_:forKey:))) {
                // 及時(shí)更新旋轉(zhuǎn)的方向，如果不更新，可能造成旋轉(zhuǎn)失敗
                _ = (UIApplication.shared.delegate as? AppDelegate)?.application(UIApplication.shared, supportedInterfaceOrientationsFor: view.window)
                UIDevice.current.setValue(value, forKey: "orientation")
                UIViewController.attemptRotationToDeviceOrientation()
            }
        }
        
        let vc = XXViewController()
        navigationController?.pushViewController(vc, animated: true)

還原旋轉(zhuǎn)方向

        AppDelegate.isPortrait = true
        if #unavailable(iOS 16) {
            let value = UIInterfaceOrientation.portrait.rawValue
            if UIDevice.current.responds(to: #selector(setValue(_:forKey:))) {
                // 及時(shí)更新旋轉(zhuǎn)的方向，如果不更新，可能造成旋轉(zhuǎn)失敗
                _ = (UIApplication.shared.delegate as? AppDelegate)?.application(UIApplication.shared, supportedInterfaceOrientationsFor: view.window)
                UIDevice.current.setValue(value, forKey: "orientation")
                UIViewController.attemptRotationToDeviceOrientation()
            }
        }
        navigationController?.popViewController()
