How to limit text input to UITextField dimensions?

Question

Swift

Good evening! Can you please tell me how to limit text input to the size of UITextField?

Answer 1

You can define text sizes with
[textField.text sizeWithAttributes: @{NSFontAttributeName:tf.font}].width;
Override the delegate method to change the text in the textfield. Next, using the method described above, determine the size of the entered text. If the dimensions are greater than frame TexField'a return false in the delegate method.
