textField.clearButtonMode = /* whatever */ doesn't work

Question

I'm creating a textField and adding it to a view like this:

UITextField *textField = [[UITextField alloc] initWithFrame:CGRectMake(/*blah blah */)];
textField.borderStyle = UITextBorderStyleRoundedRect;
textField.clearButtonMode = UITextFieldViewModeAlways;

[otherView addSubview:textField];

The text field is rendered as expected in otherView, but the clear button is never rendered, no matter what value I assign to clearButton. Anyone know what might be causing this?

Answer 1

The answer is that UITextField.clearButtonMode works. When the text field has a value, the button is there. I guess I assumed "Always" means "Always", when it really means, "when .text != nil".
