Is the project discontinued?

The project doesn't work on ios 7 and later. Be a long time no one to maintain it. And I found that the latest committed in the Fork Network Graph is @palringosteve.

We managed to get it working from our fork on iOS 6 and later with the following steps:-

• Fork/clone our JSCocoa repo.
• Import libffi-iOS v3.0.13-ios from CocoaPods:-
  • pod 'libffi', '3.0.13'
• Drag the following files from JSCocoa into your Xcode project:-
  • iPhone/iPhone.bridgesupport
  • iPhone/BurksPool.h & .m
  • iPhone/GDataDefines.h
  • iPhone/GDataXMLNode.h & .m
  • iPhone/JavascriptCore-dlsym.h & .m
  • iPhone/JavaScriptCore.h
  • iPhone/JSBase.h
  • iPhone/JSContextRef.h
  • iPhone/JSObjectRef.h
  • iPhone/JSStringRef.h
  • iPhone/JSStringRefCF.h
  • iPhone/JSValueRef.h
  • JSCocoa/JSCocoaController.h & .m
  • JSCocoa/JSCocoaPrivateObject.h & .m
  • JSCocoa/JSCocoaFFIArgument.h & .m
  • JSCocoa/JSCocoaFFIClosure.h & .m
  • JSCocoa/JSCocoaLib.h & .m
  • JSCocoa/BridgeSupportController.h & .m
  • JSCocoa/class.js
  • JSCocoa/jslint-jscocoa.js
• Initialise JSCocoa and load Javascript with the following code:-

NSString *contents = /* load JS into this variable */

// Fetch JS symbols
[JSCocoaSymbolFetcher populateJavascriptCoreSymbols];

// Load iPhone bridge support
NSString *pathToBridgeSupport = [[NSBundle mainBundle] pathForResource:@"iPhone" ofType:@"bridgesupport"];
[[BridgeSupportController sharedController] loadBridgeSupport:pathToBridgeSupport];

// Load JS class kit
JSCocoaController *cocoaController = [JSCocoaController sharedController];
[cocoaController setDelegate:self];

// Load JS main
BOOL success = [cocoaController evalJSString:contents] != NULL;

It's worth noting that as of 1 February 2015 Apple are requiring that apps built with the iOS 8 SDK include both 32- and 64-bit binaries and as of yet we have not been able to get our setup working in 64-bit mode.

@palringosteve , I have cloned your code, but I used liffi with the latest version and not used cocoapod, and I got some errors. I will follow your steps to try it again. Thanks !

Bad luck, it can't work. I got error like this:Warning: Error creating LLDB target at path '/xxxxxxx/Build/Products/Debug-iphonesimulator/xxxxxx.app'- using an empty LLDB target which can cause slow memory reads from remote devices.
