How to setup AWS lambda function to talk to the internet and VPC

I'm going to walk you through the steps for setting up a AWS Lambda to talk to the internet and a VPC. Let's dive in.

So it might be really unintuitive at first but lambda functions have three states.

1. No VPC, where it can talk openly to the web, but can't talk to any of your AWS services.
2. VPC, the default setting where the lambda function can talk to your AWS services but can't talk to the web.
3. VPC with NAT, The best of both worlds, AWS services and web.

Suppose we want to add support for a new iOS 8 API in our framework that replaces an older iOS 7 API. There are a few problems we might face:

1. The new API will crash if we call it on iOS 7
2. The new API won't compile if we build it using the iOS 7 SDK
3. The old API will raise a deprecation warning if built with a deployment target of iOS 8 and up

These three problems require three different technical solutions:

1. We can avoid calling the new API on an old OS version by using runtime detection (e.g. respondsToSelector:)
2. We can avoid compiling new APIs on old SDKs using the __IPHONE_OS_VERSION_MAX_ALLOWED macro

UIStatusBarStyle in iOS 7

• The status bar in iOS 7 is transparent, the view behind it shows through.

• The style of the status bar refers to the appearances of its content. In iOS 7, the status bar content is either dark (UIStatusBarStyleDefault) or light (UIStatusBarStyleLightContent). Both UIStatusBarStyleBlackTranslucent and UIStatusBarStyleBlackOpaque are deprecated in iOS 7.0. Use UIStatusBarStyleLightContent instead.

How to change UIStatusBarStyle

• If below the status bar is a navigation bar, the status bar style will be adjusted to match the navigation bar style (UINavigationBar.barStyle):
