iOS14崩溃问题修改建议

if (@available(iOS 13.0, *)) {
    NSEnumerator *frontToBackWindows = [UIApplication.sharedApplication.windows reverseObjectEnumerator];
    for (UIWindow *window in frontToBackWindows) {
        BOOL windowOnMainScreen = window.screen == UIScreen.mainScreen;
        BOOL windowIsVisible = !window.hidden && window.alpha > 0;
        BOOL windowLevelNormal = window.windowLevel == UIWindowLevelNormal;
        if (windowOnMainScreen && windowIsVisible && windowLevelNormal) {
            return [window hitTest:point withEvent:event];
            break;
        }
    }
// return [UIApplication.sharedApplication.keyWindow hitTest:point withEvent:event];
}

这样取最上层window而不是直接拿keyWindow.

swift版本依然会闪退，参考了上面写法

仍然会崩溃

BOOL windowIsVisible = !window.hidden && window.alpha > 0;
BOOL windowLevelNormal = window.windowLevel == UIWindowLevelNormal;
if (windowOnMainScreen && windowIsVisible && windowLevelNormal) {
return [window hitTest:point withEvent:event];
break;
}
}
// return [UIApplication.sharedApplication.keyWindow hitTest:point withEvent:event];
}

貌似只有iOS14会崩溃，iOS15高版本，都是低版本都不会崩溃。。。不过还是建议作者修复一下。
