Add a UITableView to an Existing ViewController in Xcode

Quick and dirty checklist for adding a table view to an existing view controller:

  1. Embed existing view controller in a NavigationController
  2. Drag a UITableView object into the view controller in the storyboard
  3. Make the UITableView the same width and height as the view controller and set the constraints to all four sides with no margins
  4. Create an outlet and connection for the tableView in the view controller class
  5. Add UITableViewDataSource and UITableViewDelegate to the class declaration. Your class should look something like this
    import UIKit
    class ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate {
        @IBOutlet weak var tableView: UITableView!
        override func viewDidLoad() {
  6. Select the table view, open the connections inspector and connect the table view’s dataSource and delegate methods to the View Controller object.
  7. If you’re not using static cells, open the attributes inspector and set the number of Prototype Cells to 1

Setting Up Delegates in iOS

This is copied from the iOS Apprentice tutorial on but I wanted to put it where I could easily access it. These are the basic steps for setting up a delegate pattern between two objects, where object A is the delegate for object B, and object B will send messages back to A.

  1. Define a delegate protocol for object B
  2. Give object B an optional delegate variable. This variable should be weak
  3. Make object B send messages to its delegate when something interesting happens, such as the user pressing the Cancel or Done buttons, or when it needs a piece of information. You write delegate?.methodName(self, ...)
  4. Make object A conform to the delegate protocol. It should put the name of the protocol in its class line and implement the methods from the protocol.
  5. Tell object B the object A is now its delegate


Create keyboard shortcut to toggle Document Outline in Xcode

In Xcode, open Preferences and go to the “Key Bindings” section. Type “outline” in the search filter box. Select “Show Document Outline” and double-click to the right, in the “Key” column. A text box should appear and you can type in your new shortcut. I used Cmd+9.

Installing the Html and Form Builder package back into Laravel 5

Here’s how to get the Form and Html Builder package back when using Laravel 5.

composer require illuminate/html

Then, in /config/app.php add the following to the providers and aliases arrays:

'providers' => [
'aliases' => [
	'Form'=> 'Illuminate\Html\FormFacade', 
	'HTML'=> 'Illuminate\Html\HtmlFacade',


Using Laravel 5 Auth Middleware

To restrict pages in your app to authentication status, add the middleware to the controller’s constructor.

To restrict a page to guests only (not signed in):

public function __construct()

For signed in users:

public function __construct()

If you want to make exceptions for certain methods, just pass those parameters in as an array for the second argument.

$this->middleware('auth', ['except' => 'show']);
