I'm trying to compile the code below and I'm getting the following
error.

PatternWrapper.mm:57: error: request for member 'str_pattern' in 'self-

Here's what I'm trying to compile in my project.

@interface PatternWrapper : NSObject {
    NS::Pattern *pattern;
}
...
@end

- (void)encodeWithCoder:(NSCoder *)encoder
{
       ...
      //Fails on this line here ...
    std::string pat = pattern.str_pattern();
    ...
}

Here's my native c++ method, this compiles into my dylib fine.

string NS::Pattern::str_pattern() {
    std::string str;

    std::stringstream ss;
    ss << id;

    cout << "pattern: " << ss << endl;

    return ss.str();
}

Any help much appreciated.
