How to apply text shadow to UITextView?

Actually I love UILabel. They're sweet. Now I had to go to UITextView because UILabel is not aligning text vertically to the top. Damn. One thing I really need is a text shadow. UILabel has it. UITextView seems to not have it. But I guess that guy just uses the same underlying UIKit NSString additions?? Maybe someone already has a solution for that problem? What would I overwrite?

text.layer.shadowColor = [[UIColor whiteColor] CGColor];
text.layer.shadowOffset = CGSizeMake(1.0f, 1.0f);
text.layer.shadowOpacity = 1.0f;
text.layer.shadowRadius = 1.0f;

And don't forget to add up top:

#import <QuartzCore/QuartzCore.h>

The answer with

text.layer.shadowColor

adds shadow to whole textView, perhaps it works, but it adds shadow not only to text.

The correct answer is:

CALayer *textLayer = ((CALayer *)[textView.layer.sublayers objectAtIndex:0]);
textLayer.shadowColor = [UIColor whiteColor].CGColor;
textLayer.shadowOffset = CGSizeMake(0.0f, 1.0f);
textLayer.shadowOpacity = 1.0f;
textLayer.shadowRadius = 1.0f;

Swift 3

let textView = UITextView(frame: view.frame)
textView.font = UIFont(name: "Helvetica", size: 64.0)
textView.textColor = .red
textView.text = "Hello World"

textView.layer.shadowColor = UIColor.black.cgColor
textView.layer.shadowOffset = CGSize(width: 2.0, height: 2.0)
textView.layer.shadowOpacity = 1.0
textView.layer.shadowRadius = 2.0
textView.layer.backgroundColor = UIColor.clear.cgColor

Swift 2.3

let textView = UITextView(frame: view.frame)
textView.font = UIFont(name: "Helvetica", size: 64.0)
textView.textColor = UIColor.redColor()
textView.text = "Hello World"    

textView.layer.shadowColor = UIColor.blackColor().CGColor
textView.layer.shadowOffset = CGSize(width: 2.0, height: 2.0)
textView.layer.shadowOpacity = 1.0
textView.layer.shadowRadius = 2.0
textView.layer.backgroundColor = UIColor.clearColor().CGColor
