How to edit UIAlertAction text font size and color

by

You can update text color using 

       UIAlertAction *myGoalAction = [UIAlertAction
                                    actionWithTitle:NSLocalizedString(@"My Title", @"My Title")
                                    style:UIAlertActionStyleDefault
                                    handler:^(UIAlertAction *action)
                                    {

                                    }];
       [myGoalAction setValue:[UIColor greenColor] forKey:@"titleTextColor"];

There is no efficient way to update font size.I will suggest you to use standard font size.

UIAlertAction title label is private variable and not accessible directly. Label comes inside 3 level private view hierarchy. Showing logout action with bigger font make sense for app.

There are many open source solution available.I will recommend to try this
