Join NSArray into String

Question

If I have an array with the following:

NSArray *array = [NSArray arrayWithObjects:@"dog", "brown", "kid"];

And I loop over that

for (NSString *strings in [array reverseObjectEnumerator] { }

How do I join that those individual words in one final string?

Please make some effort to search or look at the docs for `NSArray`. — rmaddy, Mar 11 '15 at 03:36

NSArray* reversedArray = [[array reverseObjectEnumerator] allObjects];
[reversedArray componentsJoinedByString:" "]

Don't loop over them. Just use:

[array componentsJoinedByString:" "]

... assuming you want a space between each word.

Have to loop over them because I am reversing them first. – qweqweqwe Mar 11 '15 at 03:09
Certainly the functional way would be to loop over the one array, reversing words and depositing them in a second array, then join the second array to make the output string. – Tommy Mar 11 '15 at 03:16
trying to do that now. Cannot figure out how to make the output string. – qweqweqwe Mar 11 '15 at 03:17
