Runtime Requirements

• Swift 4.0
• Xcode 9.2
• iOS9.0 or later

TouchVisualizer works with Swift 3 from version 3.0.0.

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, '8.0'
use_frameworks!
pod "TouchVisualizer", '~>3.0.0'

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" "3.0.0"

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

Miscellaneous

There is a similar touch visualization library called COSTouchVisualizer, which is written in Objective-C. COSTouchVisualizer supports earlier versions of iOS and is more mature. If TouchVisualizer isn't enough for you, try that!
