更改 statusBarOrientation 时应用程序生命周期错误

Question

当我打电话给UIApplication.shared.setStatusBarOrientation(.landscapeRight, animated: true)

应用程序进入后台并返回，打印

“ApplicationWillResignActive”

“ApplicationDidBecomeActive”

“ApplicationWillResignActive”

“ApplicationDidBecomeActive”

为什么？我只有两个动作

@objc fileprivate func handleApplicationWillResignActive() {
    debugPrint("ApplicationWillResignActive")
    if self.playerPlayStatus == .playing {
        self.currentPlayTime = self.player.currentTime()
        self.player.pause()
    }
}

@objc fileprivate func handleApplicationDidBecomeActive() {
    debugPrint("ApplicationDidBecomeActive")
    switch self.playerPlayStatus {
        case .pause:
            self.player.seek(to: self.currentPlayTime, toleranceBefore: kCMTimeZero, toleranceAfter: kCMTimeZero, completionHandler: { (finished) in
                if finished {
                    self.player.play()
                }
            })
        default: break
    }
}

Answer 1

ApplicationWillResignActive 和 Background 都是不同的东西。甚至前台应用程序中的应用程序也可能变为非活动状态。 所以请简述，你想做什么？
