I need to add image in Action sheet item using UIAlertController. I add using:

[alertAction setValue:image forKey:@"image"];
And results as:
The problem is that: I need the image & text to be centrally aligned and resize the height of Cancel button
How can i do that, please share some code.
Thanks!

Well, here is the Runtime Header file for UIAlertAction. You can neither change the frame of image nor you can change the height of Cancel button.
So what is the solution?
The only solution that I could figure is to make a custom view with UIVisualEffect and show/animate it like UIActionSheet. Basically you need to imitate UIActionSheet.
That said, I would like to welcome other solutions as well.
