cordova - Weird bug with phonegap ios -

-

i writing iphone application using phonegap , ios. have weird problem. have nsstring holds json string in objective c plugin class. , call callback function provided running phonegap.exec, callback neither success or failure gets called. here code:

pluginresult* pluginresult = [pluginresult resultwithstatus: pgcommandstatus_ok messageasstring: jsonstring ];         [self writejavascript:[pluginresult tosuccesscallbackstring:self.callbackid]];

my success callback alerts argument passed. weird thing that, if pass in non jsonstring example replacing jsonstring regular message, @"hello-word" works, , success callback gets called , argument gets alerted. have idea going on?

the problem had literal quote in jsonstring, jsonstring hardcoded. instead of doing this, used messageasdictionary appropriate mapped values, , still interpret data recieved javascript json object.
