Create Navigation Bar Programmatically in Swift

In your UIPopoverPresentationControllerDelegate:

func presentationController(controller: UIPresentationController, viewControllerForAdaptivePresentationStyle style: UIModalPresentationStyle) -> UIViewController? {
    let presentedViewController = controller.presentedViewController
    let navigationController = UINavigationController(rootViewController: presentedViewController)
    let dismissButton = UIBarButtonItem(barButtonSystemItem: UIBarButtonSystemItem.Done, target: self, action: "dismissPopover:")
        
    presentedViewController.navigationItem.rightBarButtonItem = dismissButton
        
    return navigationController
}
    
func dismissPopover(sender: AnyObject) {
    self.dismissViewControllerAnimated(true, completion: nil)
}

Override Application Transport Security in xCode

When you get the error App Transport Security has blocked a cleartext HTTP (http://) resource load since it is insecure. Temporary exceptions can be configured via your app’s Info.plist file., you can override the security and allow all http urls through by adding this to your info.plist file:

<key>NSAppTransportSecurity</key>  
     <dict>  
          <key>NSAllowsArbitraryLoads</key><true>  
     </true></dict>

However, before doing this, check to see if there is an https version of the url. That will work just as well, and https won’t throw that error.

    var input = NSString(data: stdin.availableData, encoding: NSUTF8StringEncoding)

Display formatted date from DatePicker in iOS

Disable Registration in Laravel 5

A new Laravel 5 installation comes with user registration out of the box. If you don’t want to use this feature, here is a clean way to disable it. Open up app\Http\Controllers\Auth\AuthController.php and add the following methods:

public function getRegister()
{
    return redirect('auth/login'); // Or wherever
}

public function postRegister()
{

}

These will override the parent methods in the AuthenticatesAndRegistersUsers trait.
