How to change the font-style and color or action sheet in objective c?

I have a action sheet 'selectedActionSheet'. I created a alertcontroller with actionsheet

UIAlertController *alertController = [selectedActionSheet valueForKey:@"_alertController"];

Now, I change the tint color as follows: 

if ([alertController isKindOfClass:[UIAlertController class]])
{
   alertController.view.tintColor = [UIColor colorWithRed:0.0/255.0 green:99.0/255.0 blue:65.0/255.0 alpha:1.0];
}

This changes the color of the tint but when I click on the action sheet, Again i see the default blue color. Can somebody help me resolving this? I am new to Objective c.

Try this code

UIActionSheet actually uses UIAlertController in iOS 8, and it has a private property _alertController.

SEL selector = NSSelectorFromString(@"_alertController");
if ([actionSheet respondsToSelector:selector])
{
    UIAlertController *alertController = [actionSheet valueForKey:@"_alertController"];
    if ([alertController isKindOfClass:[UIAlertController class]])
    {
        alertController.view.tintColor = [UIColor blueColor];
    }
}

To change all buttons colour

[[UIView appearanceWhenContainedIn:[UIAlertController class], nil] setTintColor:[UIColor redColor]];

Thanks

For font to set to alert view controller below is code...

UIAlertController *alertVC = [UIAlertController alertControllerWithTitle:@"Your Alert Title" message:@"" preferredStyle:UIAlertControllerStyleActionSheet];
NSMutableAttributedString *hogan = [[NSMutableAttributedString alloc] initWithString:@"Your alert description..."];
[hogan addAttribute:NSFontAttributeName
              value:[UIFont systemFontOfSize:50.0]
              range:NSMakeRange(24, 11)];
[alertVC setValue:hogan forKey:@"attributedTitle"];

For UIAlertController tint color...

alertVC.view.tintColor = [UIColor colorWithRed:1.0/255.0 green:99.0/255.0 blue:265.0/255.0 alpha:1.0];

Just set the alertController tintColor after the presentViewController i.e. 

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

alertController.view.tintColor = [UIColor colorWithRed:0.0/255.0 green:99.0/255.0 blue:65.0/255.0 alpha:1.0];

this will change default as well as highlighted color. Hope this will solved your problem.

If you simply want to present actionSheet, then please try below code-

UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"Hello Dear" message:@"I'm an actionSheet!" preferredStyle:UIAlertControllerStyleActionSheet];


UIAlertAction *ok = [UIAlertAction actionWithTitle:@"OK"
                                                 style:UIAlertActionStyleDefault
                                               handler:^(UIAlertAction *action){
                                                   //add code to make something happen once tapped
                                               }];

[alertController addAction: ok];

UIAlertAction *Cancel = [UIAlertAction actionWithTitle:@"Cancel"
                                             style:UIAlertActionStyleDestructive
                                           handler:^(UIAlertAction *action){
                                               //add code to make something happen once tapped
                                           }];

[alertController addAction: Cancel];

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

alertController.view.tintColor = [UIColor colorWithRed:0.0/255.0 green:99.0/255.0 blue:65.0/255.0 alpha:1.0];

actionSheet will look like this-
