TouchVG for iOS

A lightweight 2D vector drawing framework using vgcore for iOS. It uses the CoreGraphics and UIKit frameworks to render shapes and handle gestures.

Features described in Online document. Please visit demo projects (vgios-demo, vgios_examples and iOSColorPad to see more examples.

How to Compile

Compile TouchVG with CocoaPods

Type pod install or pod update --no-repo-update, then open TouchVG.xcworkspace in Xcode, then build the TouchVG or TouchVG-SVG target.

• Remove libPods-TouchVG-TouchVG-SVG.a and libPods-TouchVG.a from Link Binary With Libraries.
• libTouchVG.a does not support SVG display.
• libTouchVG-SVG.a can display SVG shapes using SVGKit.

Compile TouchVG without CocoaPods

Alternatively, you can build as one of the following methods:

• Open TouchVG/TouchVG.xcodeproj in Xcode, then build the TouchVG or TouchVG-SVG target.

  • libTouchVG.a does not support SVG display.
  • libTouchVG-SVG.a can display SVG shapes using SVGKit.

• Or type ./build.sh to compile static libraries to the output directory.

  • Type ./build.sh -arch arm64 to make for iOS 64-bit.
  • Type ./build.sh clean to remove object files.it).

Use TouchVG with CocoaPods

TouchVG is available on CocoaPods. Just add the following to your project Podfile:

pod 'TouchVG'

Or use the develop version:

pod 'TouchVG', :podspec => 'https://raw.githubusercontent.com/touchvg/vgios/develop/podspec/TouchVG.podspec'

Or add the following to use SVG rendering feature with SVGKit:

pod 'TouchVG-SVG', :podspec => 'https://raw.githubusercontent.com/touchvg/vgios/develop/podspec/TouchVG-SVG.podspec'

Then type pod install or pod update --no-repo-update. Need to copy podspec/SVGKit.podspec to ~/.cocoapods/repos/master/Specs/SVGKit/2.0/ to use the lastest version of SVGKit.

Use TouchVG without CocoaPods

• Add libTouchVG.a and libTouchVGCore.a to your project, or set OTHER_LDFLAGS as -lTouchVGCore -lTouchVG.

• If the error Undefined symbols for architecture ...in libTouchVGCore.a occurs, then change the source file which uses TouchVG as *.mm rather than *.m to link with C++ classes.

Add more shapes and commands

• You can use newproj.py to create library project containing your own shapes and commands. So the TouchVG and TouchVGCore libraries does not require changes.

  • Checkout and enter DemoCmds directory, then type python newproj.py YourCmds:

    git clone https://github.com/rhcad/DemoCmds.git
    cd DemoCmds
    python newproj.py MyCmds
