macOS returning strings (novice question)

[Darkroom]

my coffee doesn't seem to be working just yet:

if (licenseDictionary == nil)
	return @"Goodbye!";
	else
	[B]return @"Hello " [licenseDictionary objectForKey:@"Full Name"];[/B]

i can't seem to remember how to properly merge the bold statement above... "Hello " will always be there, but Full Name will change... it's a syntax error, and i'm not even sure i can change portions of a string dynamically...

any thoughts?

Can you add a "+" between the 2 items or my guess would be you need to use a concatinating method in NSString. Something like

 return [NSString stringFromObjects:@"Hello ", <Other Obj...>];

.

This woul dbe just a guess as I haven't done that yet and I haven't finished my book yet either.

the comma doesn't work, as only the last object in the sentence is executed... and adding "+" only seems to give syntax errors...

Hi,

+[NSString stringWithFormat] will do what you want:

if (licenseDictionary == nil)
    return @"Goodbye!";
else
    [B]return [NSString stringWithFormat:@"Hello %@", [licenseDictionary objectForKey:@"Full Name"]];[/B]

The %@ symbol applies to objects. The -[NSObject description] message is sent to the object, which for an NString object is equal to the string value.

I knew it was something like that. I use StringFormat alot in my C# programming but C# is all dot modifiers. Messaging is completely new to me and I do not know all the static methods in each class yet. Sorry about that!

If you really are just tacking two strings together, you might also consider -stringByAppendingString

return [@"Hello " stringByAppendingString:[licenseDictionary objectForKey:@"Full Name"]];
