ViewState

Adds an ability to check current view controller's view state and also to subscribe to view state changes notifications. Also, adds several helpful properties to easily configure some complex behaviors in xibs and storyboards.

Example

Clone the repo and then open Pods Project/ViewState.xcodeproj

Installation

CocoaPods

ViewState is available through CocoaPods. To install it, simply add the following line to your Podfile:

pod 'ViewState', '~> 2.1'

Swift Package Manager

The Swift Package Manager is a tool for automating the distribution of Swift code and is integrated into the swift compiler.

Once you have your Swift package set up, adding ViewState as a dependency is as easy as adding it to the dependencies value of your Package.swift.

⚠️ WARNING You must call ViewState.setupOnce() somewhere in you code or it won't work. The issue is that SPM doesn't support mixed source code and the framework can't load himself without Objective-C part.

dependencies: [
    .package(url: "https://github.com/APUtils/ViewState.git", .upToNextMajor(from: "2.1.0"))
]

Usage

UIViewController subclasses

• Extends UIViewController with .viewState enum property. Possible cases: .notLoaded, .didLoad, .willAppear, .didAppear, .willDisappear, .didDisappear.

You could check userInfo notification's dictionary for parameters if needed.
