in cctouchbegan method:

  for(ccsprite *s in zigblurarray)   {     if (cgrectcontainspoint(s.boundingbox, newpt1))    {        temp=s;        temp.userdata=s.userdata;        nslog(@"%d",temp.tag);         nslog(@"userdata%@",temp.userdata);     } 

finaly getting lldb error

0x170409b: movl 8(%edx), %edi exc_bad_access

the string autoreleased. userdata property of type void* , not retain object. use userobject property instead (if available in cocos2d version) or retain string.
