How to hide UITextField border?

Question

If you want to remove the textfield border you can do it directly with interface builder:

Just use this..

textOption.borderStyle = UITextBorderStyleNone;
[textOption setBackgroundColor:[UIColor clearColor]];

Swift 4 and 5 :

yourTextfield.borderStyle = .none

In Swift this worked for me :

 passwordTextField.borderStyle = UITextBorderStyle.none

If you are using Interface Builder or Storyboard, you can select the textField, go on the Attributes inspector's tab, under the option Border Style you have 4 styles to chose from, the first one is without border.

If doing it in code, this should work

textOption.borderStyle = UITextBorderStyleNone;
[textOption setBackgroundColor:[UIColor clearColor]];
