Question

I have a textfield that is hidden to start with and when the user touches a UISwitch the textfield.hidden= NO, however, the -(void)textFieldDidBeginEditing:(UITextField *)textField doesn’t kick in? any ideas

thanks

Answer 1

textFieldDidBeginEditing will get called when the textField becomes the first responder. If the user sets focus in the field to start changing it’s content, it becomes the first responder. It will not get called when the enabled state gets toggled. If it’s hidden, the user will not be able to edit it’s content.

See:

http://developer.apple.com/library/ios/#documentation/uikit/reference/UITextFieldDelegate_Protocol/UITextFieldDelegate/UITextFieldDelegate.html

This method notifies the delegate that the specified text field just
became the first responder. You can use this method to update your
delegate’s state information. For example, you might use this method
to show overlay views that should be visible while editing.

Implementation of this method by the delegate is optional.
