Is there a way to catch a “valueDidChange”-Event for a Textfield? oO
I’ve got a modalView with an UITextField.
When the UITextField is empty, the “Done”-Button in the NavigationBar should be disabled
and when there is Text entered, it should become enabled.
Right now the only way to accomplish this by using the “textFieldShouldReturn”-Method.
This works but is simply horrible for usability.
Isn’t there a way to check the requirements every time a letter is being entered or removed?
Implement
-textField:shouldChangeCharactersInRange:replacementString:.
