UISearchController在以模态方式解除时发出问题

Question

单击导航栏按钮时，我以模态方式呈现视图。此视图具有tableview视图。单击tableview行时，视图将被关闭。当我添加UISearchController时遇到问题。当我从搜索栏的结果中单击某个项目时，它会以模态方式消失但在其后面是相同的视图，但是tableview正在显示完全填充的视图。一秒后，视图以模态消失，我回到导航视图。我已经包含了一个gif来帮助直观地解释我的问题。这是代码片段。

在具有UISearchBar的视图控制器中：

在方法cellforRowAtIndexPath

中

    //Check to see if results for search bar
if ([self.searchController isActive] && ![self.searchController.searchBar.text isEqualToString:@""]) {
    restaurantCellData = self.searchResults[indexPath.row];
} else {
    restaurantCellData = self.restaurantLocations[indexPath.row];
}

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { 
    RestaurantLocationData *restaurantCellData = (RestaurantLocationData *)[self.restaurantLocations objectAtIndex:indexPath.row];
    if (self.restaurantSelectedCallBack) {
        self.restaurantSelectedCallBack(restaurantCellData);
    }
   [self.nearByTableView deselectRowAtIndexPath:indexPath animated:YES];
}

在呈现视图控制器中，我有回调块来关闭呈现的视图

vc.restaurantSelectedCallBack = ^(RestaurantLocationData *restaurantValue) {

    self.restaurantInfo = restaurantValue;
    [[API sharedInstance] setRestaurantInfoCustom:restaurantValue];

    [self dismissViewControllerAnimated:YES completion:nil];
};

vc.searchSelectedCallBack = ^(RestaurantLocationData *restaurantValue) {
    self.restaurantInfo = restaurantValue;

    [[API sharedInstance] setRestaurantInfoCustom:restaurantValue];

    [self dismissViewControllerAnimated:NO completion:nil];
};

如果您有此definesPresentationContext = true->删除它或将其设置为 false

并确保在关闭ViewController之前添加此代码

if searchController.isActive == true { // Set the search controller active to false to prevent crash searchController.isActive = false }
