Macro compiler error: "Parse Issue" when an argument name appears elsewhere - objective-c

Question

I tried making a straightforward macro for creating and showing a simple "ok" dialog box in iOS:
#define ALERT_DIALOG(title,message) \
do\
{\
UIAlertView *alert_Dialog = [[UIAlertView alloc] initWithTitle:(title) message:(message) delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];\
[alert_Dialog show];\
} while ( 0 )
If I try to use it in my code:
ALERT_DIALOG(#"Warning", #"Message");
I get the error:
Parse Issue. Expected ']'
And the error seems to be pointing at the second # right before "Message".
However, if I simply copy paste the macro I do not get this error:
NSString *title = #"Warning";
NSString *message = #"Message";
do
{
UIAlertView *alert_Dialog = [[UIAlertView alloc] initWithTitle:(title) message:(message) delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alert_Dialog show];
} while ( 0 );
Is there something against using Objective-c constructs in macros? Or is that something else?

Answer 1

The problem with your macro is that both occurrences of message in
... [[UIAlertView alloc] initWithTitle:(title) message:(message) ...
are replaced by #"Message", resulting in
.... [[UIAlertView alloc] initWithTitle:(#"Warning") #"Message":(#"Message") ...
and that causes the syntax error.
I don't think that it is really worth defining this as a macro, but if you do, you have to use macro arguments which do not occur at places where they should not be expanded, e.g.
#define ALERT_DIALOG(__title__,__message__) \
do\
{\
UIAlertView *alert_Dialog = [[UIAlertView alloc] initWithTitle:(__title__) message:(__message__) delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];\
[alert_Dialog show];\
} while ( 0 )
or similar.

Instead of declaring it as a macro, you can declare it as a C function instead:
void ALERT_DIALOG(NSString *title, NSString *message) {
UIAlertView *alert_Dialog = [[UIAlertView alloc] initWithTitle:(title) message:(message) delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];\
[alert_Dialog show];
}
