Thank you very much! The cursor's height seems to be same with the height of the textField. So I set a constraint on the textfield's height and increase the font size. – Mandeville

Answer 2

I accidentally stumbled across this question and even though it is a little old I feel compelled to answer it since the accepted answer actually isn't correct.

You can indeed change the height (or width) of the cursor. Just subclass the UITextField and override this method:

- (CGRect)caretRectForPosition:(UITextPosition *)position {
    CGRect rect = [super caretRectForPosition:position];
    rect.size.height = 42;
    return rect;
}

hi, i tried your answer and it worked so +1 for you, but when i changed the keyboard (from English(indian) to Japanes(kana) ) , the caret moves up when i enter a single character. Xcode 10.1 & Swift – Bigname

Thank you, it is a great answer! It should be selected as correct. It is far more flexible and reliable solution. in my case, I also needed to change cursor's position according to different conditions. I could achieve it through this method – Florey

Answer 3

Suppose your UITextField name is uiTextField. To set font size add the code below

_uITextField.font = UIFont.systemFont(ofSize: 10)
