How to convert std::string to NSString?

Question

Hi I am trying to convert a standard std::string into an NSString but I'm not having much luck.

I can convert successfully from an NSString to a std::string with the following code

NSString *realm = @"Hollywood"; std::string REALM = [realm cStringUsingEncoding:[NSString defaultCStringEncoding]]; 

However I get a compile time error when I try the following

NSString *errorMessage = [NSString stringWithCString:REALM encoding:[NSString defaultCStringEncoding]]; 

The error I get is

Cannot convert 'std::string' to 'const char*' in argument passing 

Am I missing something here?

Thanks in advance.

Get c-string out of std::string for conversion:

NSString *errorMessage = [NSString stringWithCString:REALM.c_str()                                     encoding:[NSString defaultCStringEncoding]];
