Runtime Requirements

Swift 4.0
Xcode 9.2
iOS9.0 or later

TouchVisualizer works with Swift 5.2 from version 4.0.0.

Installation and Setup

Note: Embedded frameworks require a minimum deployment target of iOS 9.0.

Information: To use TouchVisualizer with a project targeting iOS 8.0 or lower, you must include the TouchVisualizer.swift source file directly in your project.

Installing with CocoaPods

CocoaPods is a centralised dependency manager that automates the process of adding libraries to your Cocoa application. You can install it with the following command:

$ gem update
$ gem install cocoapods
$ pods --version

To integrate TouchVisualizer into your Xcode project using CocoaPods, specify it in your Podfile and run pod install.

platform :ios, '9.0'
use_frameworks!
pod "TouchVisualizer", '~> 4.0'

Installing with Carthage

Carthage is a decentralised dependency manager that automates the process of adding frameworks to your Cocoa application.

You can install Carthage with Homebrew using the following command:

$ brew update
$ brew install carthage

To integrate TouchVisualizer into your Xcode project using Carthage, specify it in your Cartfile:

github "morizotter/TouchVisualizer" "4.0.0"

Manual Installation

To install TouchVisualizer without a dependency manager, please add all of the files in /Pod to your Xcode Project.

Usage

To start using TouchVisualizer, write the following line wherever you want to start visualising:

import TouchVisualizer

Then invoke visualisation, by calling:

Visualizer.start()

and stop the presentation like this:

Visualizer.stop()

Get touch locations by this:

Visualizer.getTouches()

It is really simple, isn't it?

Customisation

TouchVisualizer also has the ability to customize your touch events. Here is an example of what can be customized:

var config = Configuration()
config.color = UIColor.redColor()
config.image = UIImage(named: "YOUR-IMAGE")
config.showsTimer = true
config.showsTouchRadius = true
config.showsLog = true
Visualizer.start(config)

Configuration properties

name	type	description	default
color	`UIColor`	Color of touch point and text.	default color
image	`UIImage`	Touch point image. If rendering mode is set to `UIImageRenderingModeAlwaysTemplate`, the image is filled with color above.	circle image
defaultSize	`CGSize`	Default size of touch point.	60 x 60px
showsTimer	`Bool`	Shows touch duration.	false
showsTouchRadius	`Bool`	Shows touch radius by scaling touch point. It doesn't work on simulator.	false
showsLog	`Bool`	Shows log.	false
