Question

Silly as it may sound, I am trying to write a simple function in objective-c which returns a string and displays it, the following code nearly works but I can’t get printf to accept the functions return value …

NSString* getXMLElementFromString();

int main(int argc, char *argv[])
{
    printf(getXMLElementFromString());
    return NSApplicationMain(argc,  (const char **) argv);
}

NSString* getXMLElementFromString() {
    NSString* returnValue;
    returnValue = @"Hello!";
    return returnValue;
}

Answer 1

I don’t know that printf can handle an NSString. Try somethign like:

 printf ("%s\n", [getXMLElementFromString()cString]);
