#PNChart
You can also find swift version at here https://github.com/kevinzhow/PNChart-Swift
A simple and beautiful chart lib with animation used in Piner and CoinsMan for iOS
PNChart works on iOS 7.0+ and is compatible with ARC projects. If you need support for iOS 6, use PNChart <= 0.8.1. Note that 0.8.2 supports iOS 8.0+ only, 0.8.3 and newer supports iOS 7.0+.
It depends on the following Apple frameworks, which should already be included with most Xcode templates:
- Foundation.framework
- UIKit.framework
- CoreGraphics.framework
- QuartzCore.framework
You will need LLVM 3.0 or later in order to build PNChart.
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
