Is it possible to add a hyperlink to a UIAlertController?

问题

Technology: Objective-C, xCode 7

@property (nonatomic, copy) NSString *notes;
@synthesize notes;

example.notes = @"Click <a href='http://www.google.com'>here</a>";

NSString *msg = [@"" stringByAppendingFormat:@"%@", myAnnotation.notes];

UIAlertController *alertViewController = [UIAlertController alertControllerWithTitle: @"Title of Alert Box" message: msg preferredStyle: UIAlertControllerStyleAlert];
[alertViewController addAction: [UIAlertAction actionWithTitle: @"Close" style: UIAlertActionStyleCancel handler: nil]];
[self presentViewController: alertViewController animated: YES completion: nil];

Trying to get a link to appear in the Alert Box, but having no luck. Just outputs as plain text.

Is this even possible? If so, using my example above, how would you implement it?

Just like this.

UIAlertController* alert = [UIAlertController alertControllerWithTitle:@"Alert Title"
                               message:msg
                               preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction* defaultAction = [UIAlertAction actionWithTitle:@"GO" 
                                   style:UIAlertActionStyleDefault    
                                   handler:^(UIAlertAction * action) 
{
    NSString *urlString = @"someurl.com";
    NSURL *url = [NSURL URLWithString:urlString];
    if (NSClassFromString(@"SFSafariViewController"))
    {
        SFSafariViewController *safariViewController = [[SFSafariViewController alloc]initWithURL:url];
        safariViewController.delegate = self;
        [self presentViewController:safariViewController animated:YES completion:nil];
    }
    else
    {
        if ([[UIApplication sharedApplication] canOpenURL:url])
        {
            [[UIApplication sharedApplication] openURL:url];
        }
    }
}];
[alert addAction:defaultAction];
[self presentViewController:alert animated:YES completion:nil];

I've added code for opening link in SFSafariController only for iOS 9. In iOS 8 devices, it will open with safari browser as SFSafariController does not exist in iOS 8. This is done because apple now considers it bad user experience to exit the app to go to external links. So you can either open links in a web view or Safari Controller.
