Indicator within alert, indicator doesn't show up (resolved using UIAlertController)

I'm trying to follow the accepted solution from here on Xcode 6.3.2 but the indicator refuses to show up or I can't see it on my iPhone 6 plus for some reason. No error messages, the alert with the title, etc shows up and empty space.

What am I doing wrong? The alert is triggered after the connect button on the app is pressed...

UIAlertView *alertWithInd;
UIActivityIndicatorView *alertInd;
alertWithInd = [[UIAlertView alloc] initWithTitle:@"Connecting..." message:@"Please wait...\n\n\n\n\n\n\n\n\n" delegate:self cancelButtonTitle:nil otherButtonTitles:nil];

alertInd = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleGray];
alertInd.frame=CGRectMake(0, 20, 270, 100);
[alertInd startAnimating];

[alertWithInd addSubview:alertInd];
[alertWithInd show];

After doing some further research and for anyone else interested in finding the solution in one spot (as there are parts in many other posts) I post the code that uses an UIAlertController (instead of a UIAlert), has an indicator and also the code for dismissal without the need for a button to be pressed.

UIAlertController *alertController = [UIAlertController
                                      alertControllerWithTitle:@"Connecting"
                                      message:@"Please wait...\n\n"
                                      preferredStyle:UIAlertControllerStyleAlert];


UIActivityIndicatorView *alertInd = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleGray];
alertInd.frame=CGRectMake(0, 40, 270, 100);
[alertInd startAnimating];

[alertController.view addSubview:alertInd];


id rootViewController=[UIApplication sharedApplication].delegate.window.rootViewController;
if([rootViewController isKindOfClass:[UINavigationController class]])
{
    rootViewController=[((UINavigationController *)rootViewController).viewControllers objectAtIndex:0];
}
[rootViewController presentViewController:alertController animated:YES completion:nil];

// to dismiss the alert with no button use:
[alertController dismissViewControllerAnimated:YES completion:nil];

I was faced same issue in my one of project . I have resolved this in this way -

Define below in .h file 

@property (strong, nonatomic) UIAlertView *alertViewProcessing;

.m file - 

-(void)processing
{


    self.alertViewProcessing = [[UIAlertView alloc] initWithTitle:@"Requesting...." message:nil delegate:nil cancelButtonTitle:nil otherButtonTitles: nil];
    UIActivityIndicatorView *indicator = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleGray];
    [indicator startAnimating];


    if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"8.0"))
    {
        UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0.0, 0.0, 40.0, 40.0)];
        view.backgroundColor =[UIColor clearColor];
        indicator.frame = CGRectMake(120.0, 0.0, 20.0, 20.0 );
        [view addSubview:indicator];

        [self.alertViewProcessing setValue:view forKey:@"accessoryView"];
    }
    else
    {
        [self.alertViewProcessing setValue:indicator forKey:@"accessoryView"];
    }

    [self.alertViewProcessing show];

}

Subclassing Notes

The UIAlertView class is intended to be used as-is and does not support subclassing. The view hierarchy for this class is private and must not be modified.
