ios UISearchController ios 11.4.1版本 Application tried to present modal view controller on itself

最近发现bugly记录了这样的bug,都集中在了ios 11.4.1版本上面,并且只出现了 2次，无法复现，所以就是看代码，各种查阅了,最后找了这么一个有用的文章https://stackoverflow.com/questions/31487824/error-application-tried-to-present-modal-view-controller-on-itself-while-activ

[searchController setActive：NO]设置UISearchController 的active状态来解决UISearchController重复弹出viewController,因为active是UISearchController的活跃状态，设置之后将会无法弹出。因此

- (void)didDismissSearchController:(UISearchController *)searchController

{

    BLYLogInfo(@"----------%s--" , __PRETTY_FUNCTION__);

    [searchController setActive:NO];

}

在UISearchControllerDelegate的dismiss方法上面将UISearchControlleter Active设置为NO，后续待观察
