UIAlertController title is always nil with iOS8

问题

I have a problem since iOS8 and Xcode 6.0.1, the title of my alert dialogs doesn't appear. So I changed my UIAlertView to UIAlertController but I have the same issue...

The title of my alert is always to nil and the displaying is very ugly because I don't have the serparator lines.

Do you know why i have this ?

    UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"title" message:@"message" preferredStyle:UIAlertControllerStyleAlert];

    [alert addAction:[UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault handler:^(UIAlertAction *action) {
        [self dismissViewControllerAnimated:YES completion:nil];
    }]];

    [self presentViewController:alert animated:YES completion:nil];

But this is the result

(lldb) po alert.title
nil
(lldb) po alert.message
message

Thank you.

Try calling the UIAlertView like this:

[[[UIAlertView alloc] initWithTitle:<#title#>
                            message:<#msg#>
                           delegate:nil
                  cancelButtonTitle:<#cancel button#>
                  otherButtonTitles:<#buttons#>,nil] show];

Does the title still not show?
