I've replaced the still crash tip:

Sep 19 14:18:35 XXXX[718] : CGContextTranslateCTM: invalid context 0x0. If you want to see the backtrace, please set CG_CONTEXT_SHOW_BACKTRACE environmental variable. Sep 19 14:18:35 XXXX[718] : CGContextRestoreGState: invalid context 0x0. If you want to see the backtrace, please set CG_CONTEXT_SHOW_BACKTRACE environmental variable.

@BadSuNian I have same problem. I thought it was because of JSONKit, but I still have crash after applied @h532930330's patch. And then I find out that another third party library TXJSONKitSerializing defines same category method which crashes app. How I fix: I changed JSONKit's category method name to another to avoid using TXJSONKitSerializing because TXJSONKitSerializing is inside some lib.a so I can't change. Chinese comment (中文解释) 我根据上面的comment解决后，还是有问题，后来发现，在运行的时候，方法JSONString其实是调用了某个第三方库的TXJSONKitSerializing定义的方法，而不是JSONKit里的。 看样子，在运行时，第三方库的方法覆盖了源码里的同样的方法。 解决办法就是，把JSONKit里的方法加个前缀，然后代码里面使用这个加了前缀的方法，这样就不会误用到TXJSONKitSerializing里的。 这也强调了一个写Category方法的要求，尤其是提供给别人使用的第三方库的时候，一定要加上前缀，以防影响到使用者。
