How to determine the length of the text in a UITextfield

Question

I have a UITextField from which I'd like to determine the width of the entered text.

The bounds property has just the size of the Textfield but not of the text

Answer 1

CGFloat width =  [aTextField.text sizeWithFont:aTextField.font].width;

Answer 2

Now that sizeWithFont: is deprecated in iOS 7.0 use

CGFloat width =  [tf.text sizeWithAttributes: @{NSFontAttributeName:tf.font}].width;

Answer 3

If you are looking for character count it is this

int textLength = [someTextField.text length]

If you are looking for pixel width try this

CGSize size = [someTextField.text sizeWithFont:someTextField.font];
//size.width contains the width

Answer 4

In Swift 3.0

let size:CGSize = aTextField.attributedText.size()
let height = size.height
let width = size.width

Answer 5

CGSize size = [myTextField.text sizeWithFont:myTextField.font];
