How to apply text shadow to UITextView?

Question

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. O

This Swift example uses the attributed string method of adding shadow to text. See this answer for more about attributed strings in Swift. This method (as opposed to using the layer method) gives you the flexibility to set the shadow on a range of text if you want to.

// Create a string
let myString = "Shadow"

// Create a shadow
let myShadow = NSShadow()
myShadow.shadowBlurRadius = 3
myShadow.shadowOffset = CGSize(width: 3, height: 3)
myShadow.shadowColor = UIColor.gray

// Create an attribute from the shadow
let myAttribute = [ NSAttributedStringKey.shadow: myShadow ]

// Add the attribute to the string
let myAttrString = NSAttributedString(string: myString, attributes: myAttribute)

// set the attributed text on a label
myLabel.attributedText = myAttrString // can also use with UITextView
