iOS-8 and later - UITableView inside an UIAlertController

I know how to add any

Custom UI
inside
UIAlertView
by using
accessoryView
like
UITableView
but I am now curious that if we still have option to add
Custom UI
inside an
UIAlertController
, what I am wanting to have is a
UITableViewController
inside an
UIAlertController
with clear understanding.

Answer

Courtesy of StackOverflow users I was able to do this task.

Here is my code:

UIViewController *controller = [[UIViewController alloc]init];
UITableView *alertTableView;
CGRect rect;
if (array.count < 4) {
    rect = CGRectMake(0, 0, 272, 100);
    [controller setPreferredContentSize:rect.size];

}
else if (array.count < 6){
    rect = CGRectMake(0, 0, 272, 150);
    [controller setPreferredContentSize:rect.size];
}
else if (array.count < 8){
    rect = CGRectMake(0, 0, 272, 200);
    [controller setPreferredContentSize:rect.size];

}
else {
    rect = CGRectMake(0, 0, 272, 250);
    [controller setPreferredContentSize:rect.size];
 }

alertTableView  = [[UITableView alloc]initWithFrame:rect];
alertTableView.delegate = self;
alertTableView.dataSource = self;
alertTableView.tableFooterView = [[UIView alloc]initWithFrame:CGRectZero];
[alertTableView setSeparatorStyle:UITableViewCellSeparatorStyleSingleLine];
[alertTableView setTag:kAlertTableViewTag];
[controller.view addSubview:alertTableView];
[controller.view bringSubviewToFront:alertTableView];
[controller.view setUserInteractionEnabled:YES];
[alertTableView setUserInteractionEnabled:YES];
[alertTableView setAllowsSelection:YES];
UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"Title" message:@"Message" preferredStyle:UIAlertControllerStyleAlert];
[alertController setValue:controller forKey:@"contentViewController"];
UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:@"Cancel" style:UIAlertActionStyleDestructive handler:^(UIAlertAction *action) {

}];
[alertController addAction:cancelAction];
[self presentViewController:alertController animated:YES completion:nil];
