SideViewManager

Description

SideViewManager enables developers the ability to add swipe in/out functionality to a view in 1 line using 1 dependency. SideViewManager allows the frames for on and off screen to be customizable, so that the position of "on" and "off" can defined by the developer. In addition, there are gestures for swiping the view on and off screen as well as tap away to dismiss the view.

Example

To run the example project, clone the repo, and run pod install from the Example directory first.

Requirements

Requires iOS 8.0 or later
Requires Automatic Reference Counting (ARC)

Features

Swipe view on and off screen
Custom on and off positions
Tap to dismiss
Manual presentation and dismissal
Delegate to listen for movement of the SideView

Future Features

Open an issue to begin the discussion about features to add. I'd like this pod to be lightweight, but also versatile.

Installation

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

pod 'SideViewManager'

You can add import SideViewManager to your classes with the following line:

import SideViewManager

Usage

Initialization

There are two ways to initialize a SideViewManager, either with a UIViewController (the manager will cooperate with the controller's view) or with a UIView. Then, the view must also be given an endingFrame and startingFrame. These frames basically specify the two positions that the screen transitions between.

let startingFrame = CGRect(x: self.view.frame.width, y: 0, width: self.view.frame.width, height: self.view.frame.height)
let endingFrame = self.view.frame

// Initialize with controller
let sideController = UIViewController()
let manager = SideViewManager(controller: sideController, startingFrame: startingFrame, endingFrame: endingFrame)

// Initialize with view
let sideView = UIView()
let manager = SideViewManager(view: sideView, startingFrame: startingFrame, endingFrame: endingFrame)

There are gestures available for swiping the view on and off screen, as well as tapping away the view to dismiss it. These values should be set after your view has appeared, so preferrably in your viewDidAppear(anaimated:) function.

// Allows the view to be swipable between on and off frames
manager.setSwipeGesture(isEnabled: true)

// Allows the view to be tapped to dismiss
manager.setDismissGesture(isEnabled: true)

Then, the next step is you can set the swipeDirection on your SideViewManager instance in order to specify the direction that swiping the screen on and off screen can work. SideViewManager's swipe gesture is bi-directional, so the swipe direction is either .horizontal (left and right) or .vertical (up and down). By default the swipeDirection is horizontal.

manager.swipeDirection = .horizontal
manager.swipeDirection = .vertical

Lastly, in terms of usage, there are functions to manually present and dismiss the SideView, as well as manually set the offset of the SideView.

// Presents the sideView with an animation speed of 1 second. 
// By default, the animation speed is 0.25. 
// To remove animation set the animationDuration value to 0.
manager.present(animationDuration: 1.0)

// Dismisses the sideView with an animation speed of 0.5 seconds. 
// By default, the animation speed is 0.25.
// To remove animation set the animationDuration value to 0.
manager.dismiss(animationDuration: 0.5)

// Moves the sideView off screen (0 is off-screen, 1 is on-screeen, 0.5 is halfway, etc.)
// Set the duration of time it takes to move the sideView to this position.
manager.move(to: 0.0, duration: 1.0)

Delegate

There are two delegate methods for listening to changes to the SideViewManager

// The SideViewManager did finish moving to a given offset, where 0 is off-screen, 1 is on-screen, and values can vary between 0 and 1.
func didFinishAnimating(to offset: CGFloat)

/// Listen for whether a gesture (dismiss or swipe) in the SideViewManager has been enabled/disabled
func didChange(gesture: UIGestureRecognizer, to isEnabled: Bool)
