用户可以切换到禁用了用户交互的UITextField

Question

I have disabled user interaction in a UITextField:

textField.isUserInteractionEnabled = false

and still (at least in the simulator) the user can tab to that field and enter data. To work around this, I've had to do the following in my UITextFieldDelegate:

func textFieldShouldBeginEditing(_ textField: UITextField) -> Bool {
    // This seems really odd.
    return isUserInteractionEnabled
}

A bug in the UITextField? Or behavior as intended? (This is with iOS 11.4 running under Xcode 9.4.1.)

Answer 1

Try setting textField.enabled = false.

This is a property of UIControl interface on UIView.

From UIControl.h comment: if NO, ignores touch events and subclasses may draw differently.
