iphone - [NSCFString stringValue]: unrecognized selector sent to instance -

-

my created application crashed when executing below lines of code c1 integer variable.

nsstring *path = c1.stringvalue;

shows following error in log:

-[nscfstring stringvalue]: unrecognized selector sent instance 0x5566e80 2011-05-11 14:56:15.813 e-trend[1552:207] uncaught exception happens!! (nsinvalidargumentexception: -[nscfstring stringvalue]: unrecognized selector sent instance 0x5566e80) 2011-05-11 14:56:15.816 e-trend[1552:207] * terminating app due uncaught exception 'nsinvalidargumentexception', reason: '-[nscfstring stringvalue]: unrecognized selector sent instance 0x5566e80'

if have idea solve issue , please answer accordingly.

where c1 integer variable

what mean? how c1 declared?

if c1 int, c1.stringvalue wouldn't compile.

the dot syntax works when object reference -- c1 -- of specific object reference type (not id) , reference-- class-- responds method.

so, have like:

mythingthatrespondstostringvalue *c1;

and are, somewhere, assigning instance of nsstring variable leads crash.
