title: UITextField and UIButton are not clickable
body: <p>I am implementing simple UI for URL checking. For this, I used textField and button objects. </p>
  
  <p>When I run the program first time, textField and button will work fine but when I click on the done button on the keyboard then the keyboard is dismissed. Now I want to edit the textField and when I am trying to click on textField it is not clickable or not showing the keyboard. same thing happened to the button, next button is also not clickable.</p>
  
  <p>Here is the code I wrote for the button action</p>
  
  <pre><code>- (IBAction)urlNextButtonAction:(id)sender {
  
      [self.urlTextfield resignFirstResponder];
  
      [SVProgressHUD showWithStatus:@"Verifying URL"];
      [self URLValidationMethod];
  }
  </code></pre>
