title: Build simple iOS app with text field that prints value using NSLog
body: <p>I'm trying to learn Objective C and iOS development, but am having trouble. I am trying to create a very basic app that has a text field and that prints out the value entered into the text field using NSLog when the return key is pressed. I have added the text field via storyboard, but am unsure how to create the delegate method needed to make this work. I have thus far added the following code to the <strong>ViewController.h</strong> file: <code>@property (weak, nonatomic) IBOutlet UITextField *textfld;</code></p>
  
  <p>Thanks in advance for any help.</p>
