iPhone-X-如何强制用户两次滑动主屏幕指示器以进入主屏幕

问题描述

我正在使用下面的代码在iPhone X上隐藏主页指示器，该指示器在模拟器中可以正常工作.

I'm using the code below to hide the home indicator on iPhone X, which is working fine in the emulator.

-(BOOL)prefersHomeIndicatorAutoHidden
{
    return YES;
}

但是即使它被隐藏了，我仍然可以从底部向上滑动，并且游戏进入主屏幕.

But even though it's hidden, I am still able to swipe up from the bottom and my game goes to the home screen.

我看过一些游戏，用户必须向上滑动一次以显示主屏幕指示器，然后再次向上滑动以进入主屏幕.

I have seen a few games where the user has to swipe up once to bring up the home indicator and swipe up again to go to the home screen.

那么，如何强制用户两次滑动主屏幕指示器以使用Objective-C进入iOS 11的主屏幕?

So, how can I force the user to swipe the home indicator twice to go to the home screen in iOS 11 with Objective-C?

这种行为对于全屏游戏是必需的.

This behavior is required for full-screen games.

推荐答案

我遇到了同样的问题.

PrefersHomeIndicatorAutoHidden必须返回NO，但PreferredScreenEdgesDeferringSystemGestures也必须被覆盖并返回UIRectEdgeBottom.

PrefersHomeIndicatorAutoHidden must return NO but also PreferredScreenEdgesDeferringSystemGestures must be overridden and return UIRectEdgeBottom.

override var prefersHomeIndicatorAutoHidden: Bool {
  return false
}

override var preferredScreenEdgesDeferringSystemGestures: UIRectEdge {
  return UIRectEdge.bottom
}
