Not Able to get graph using cocoapods - ios

Question

I am following this github project : Here.In that they mentioned to do :
Cocoapods
CocoaPods is the recommended way to add PNChart to your project.
Add a pod entry for PNChart to your Podfile pod 'PNChart'
Install the pod(s) by running pod install.
Include PNChart wherever you need it with #import "PNChart.h".
What i did is :
start the new project and add all frame works.
then i use terminal to create podfile like ( touch podfile )
then i move to my project folder to podfile file and i add this code
pod 'PNChart', '~> 0.8.7'
Then i use pod install to run .
then i add PNChart folder to my project, after that when i build i am not able to see my graph.
But when i download their project from github , then when i see their podfile file .its like this below code:
source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '6.0'
pod 'UICountingLabel','~> 1.2.0'
target :PNChartTests do
pod 'Expecta'
end
But when i copy these files to my podfile and when i run pod install in terminal . i am getting error no PNChartTest are seen
What i need to do first to work with line graph. please some one guid me to do,thanks!

Create new project.
Right click on 'Xcode project' in Xcode project navigator and choose others & empty file name 'Podfile' and select the destination as project directory level (Podfile should be at the xcodeproject file level) and add following lines
pod 'PNChart'
Close xcodeproject
Go to project directory and run the 'pod install' command from the termial
Open workspace i.e. .xcworkspace file
Import charts file in view controller such as
#import "ViewController.h"
#import "PNChart.h"
