Class Form not found

Begin by installing this package through Composer. Edit your project's composer.json file to require laravelcollective/html.

"require": {
    "laravelcollective/html": "5.1.*"
}

Next, update Composer from the Terminal:

composer update

Next, add your new provider to the providers array of config/app.php:

  'providers' => [
    // ...
    Collective\Html\HtmlServiceProvider::class,
    // ...
  ],


Finally, add two class aliases to the aliases array of config/app.php:


  'aliases' => [
    // ...
      'Form' => Collective\Html\FormFacade::class,
      'Html' => Collective\Html\HtmlFacade::class,
    // ...
  ],

Hide Tab Bar

You might have a table view in a tab bar controller, and in certain view you would like to hide the tab bar.

However, the scroll view's(table view)'s height/constraints have been defined when you enter the view controller, hence self.tabBarController?.tabBar.hidden = true will mess up your scrollable height

Add the following line to prepareforsegue when you enter that controller

segue.destinationViewController.hidesBottomBarWhenPushed = true

disable cell highlight/select color

We don't always want our SDK to "act smart" XD

In a table view cell there is always a highlight background color upon tap, if you don't like it simply disable selection style with

cell.selectionStyle = UITableViewCellSelectionStyle.None

How to call tableview controller method within cell class

I was removing cells from table view today with a button in the cell.

So after calling the remove function from the API, here comes the question, how do you refresh the table view's content.

Firstly, create a protocol method in your cell class

protocol BookingTableViewCellDelegate {

    func reloadTableViewData()

}

then 

var delegate: BookingTableViewCellDelegate?

in table view controller

    func reloadTableViewData() {

        println("reloading data")

        self.items.removeAllObjects()

        getBookings()

        self.myBookingTableView.reloadData()

    }

and add 

cell.delegate = self at cellForRowAtIndexPath

then finally, in your cell class:

self.delegate?.reloadTableViewData()
