相信有些人在iPhone X上玩游戏的时候,总是误触底部白条(Home键指示器,暂且先叫“底部白条”),专业术语:“App需要有从状态栏下拉或底部栏上滑的操作,而这个会和系统的下拉或上滑调出通知中心手势冲突。” 。 于是开始 百度一下
这是什么鬼这并不是我们想要的解决办法....... how to 办?
经过一系列的尝试, 在iOS11之后iOS增加的新的API,是关于解决手势冲突的问题。
@interface UIViewController (UIScreenEdgesDeferringSystemGestures)
// Override to return a child view controller or nil. If non-nil, that view controller's screen edges deferring system gestures will be used. If nil, self is used. Whenever the return value changes, -setNeedsScreenEdgesDeferringSystemGesturesUpdate should be called.
- (nullable UIViewController *)childViewControllerForScreenEdgesDeferringSystemGestures API_AVAILABLE(ios(11.0)) API_UNAVAILABLE(watchos, tvos);
// Controls the application's preferred screen edges deferring system gestures when this view controller is shown. Default is UIRectEdgeNone.
- (UIRectEdge)preferredScreenEdgesDeferringSystemGestures API_AVAILABLE(ios(11.0)) API_UNAVAILABLE(watchos, tvos);
// This should be called whenever the return values for the view controller's screen edges deferring system gestures have changed.
- (void)setNeedsUpdateOfScreenEdgesDeferringSystemGestures API_AVAILABLE(ios(11.0)) API_UNAVAILABLE(watchos, tvos);
@end
API我们知道了,可是加到哪里?然后通过分析Unity打包后的Xcode工程,在工程目录
Classes->UI->UnityViewControllerBaseiOS.mm
的脚本中,发现被重写的方法,如下:
- (UIRectEdge)preferredScreenEdgesDeferringSystemGestures
{
UIRectEdge res = UIRectEdgeNone;
if(UnityGetDeferSystemGesturesTopEdge())
res |= UIRectEdgeTop;
if(UnityGetDeferSystemGesturesBottomEdge())
res |= UIRectEdgeBottom;
if(UnityGetDeferSystemGesturesLeftEdge())
res |= UIRectEdgeLeft;
if(UnityGetDeferSystemGesturesRightEdge())
res |= UIRectEdgeRight;
return res;
}
我们只需要改成如下即可:
UIRectEdge res = UIRectEdgeNone;
//if(UnityGetDeferSystemGesturesTopEdge())
//res |= UIRectEdgeTop;
//if(UnityGetDeferSystemGesturesBottomEdge())
//res |= UIRectEdgeBottom;
//if(UnityGetDeferSystemGesturesLeftEdge())
//res |= UIRectEdgeLeft;
//if(UnityGetDeferSystemGesturesRightEdge())
//res |= UIRectEdgeRight;
return UIRectEdgeAll;
设置后第一次下拉“底部白条”只会展示指示器,继续下拉才能将通知中心拉出来。如果返回UIRectEdgeNone则会直接下拉出来。
