How do I add a space between two concatenated NSStrings?

Question

I have three string objects:

NSString *firstName;
NSString *lastName;
NSString *fullName;

The values for firstName and lastName are received from NSTextFields.

I then want to concatenate the two strings and place the result in fullname.

This is the code that I'm using:

fullName = [firstName stringByAppendingString:lastName];

However, the result does not put a space between the two names (e.g. JohnSmith).

How do I add in the space? I'd like the result to look like (John Smith).

Answer 1

The simplest way is this:

fullname = [[firstName stringByAppendingString:@" "] stringByAppendingString:lastName];

i.e. append the space, and then append the lastName.

Answer 2

I'm amazed by the length of the other answers:

fullname = [NSString stringWithFormat:@"%@ %@", firstname, lastname];

Answer 3

fullName = [@[firstName, lastName]
             componentsJoinedByString:@" "];

Answer 4

That is normal. You will have to add the space yourself.

(NSString*) description { return [[[NSString alloc] 
                          initWithFormat:" %@ %@”, 
                          firstname, 
                          lastname] autorelease]; }
