Installing LFHeatMap via CocoaPods

Step 1: Download CocoaPods

CocoaPods is a dependency manager for Objective-C, which automates and simplifies the process of using 3rd-party libraries like LFHeatMap in your projects.

CocoaPods is distributed as a ruby gem, and is installed by running the following commands in Terminal.app:

$ sudo gem install cocoapods
$ pod setup

Depending on your Ruby installation, you may not have to run as sudo to install the cocoapods gem.

Step 2: Create a Podfile

Project dependencies to be managed by CocoaPods are specified in a file called Podfile. Create this file in the same directory as your Xcode project (.xcodeproj) file:

$ touch Podfile
$ open -e Podfile

TextEdit should open up showing an empty file. You just created the pod file and opened it! Ready to add some content to the empty pod file?

Copy and paste the following lines into the TextEdit window:

platform :ios, '5.0'
pod 'LFHeatMap'

Make sure the quotes are straight, not slanted/apostrophes. If TextEdit gives you trouble, use Sublime, vi, or copy/paste the code above instead of typing it in.

Step 3: Install Dependencies

Now you can install the dependencies in your project:

$ pod install

From now on, be sure to always open the generated Xcode workspace (.xcworkspace) instead of the project file when building your project:

$ open <YourProjectName>.xcworkspace

Step 4: Dive In!

At this point, everything's in place for you to start using LFHeatMap. Import the headers (#import <LFHeatMap.h>) and get to it!
