Getting an Instance Method to return a string

Question

This should be simple but I'm clearly doing something painfully wrong. I want to write a test method that returns a string.

In my classTest.h I have

 @interface classTest : NSObject

 - (NSString *)returnTestString; 

 @end

classTest.m

- (NSString *)returnTestString; {
    NSString *currentTestString = @"123.456";
    return currentTestString;
}

and in the calling module.m I have #import "classTest.h" and then to call the module if I add [classTest returnTestString];

I get

"No known class method for selector 'callTestString'"

Can some point out the bleedin' obvious? - thanks EH

And the reason is that `-` signifies instance methods. If you want a class method, use `+` instead. — , Jun 17 '13 at 21:02
Well, the method above is named "returnTestString", not "callTestString". — Hot Licks, Jun 17 '13 at 21:15
Your code is horribly formatted. The actual problem is the ; after returnTestString in your implementation file (.m) — Taum, Jun 17 '13 at 21:22
Many thanks, I had tried this with a + but got a different compiler error - apologies for the final bit of layout - looked OK before I submitted it. — Edward Hasted, Jun 17 '13 at 21:44
@Taum: Actually that semicolon is not against the language. Try it. It is allowed to have a semicolon there. — yonosoytu, Jun 17 '13 at 21:51

 @interface ClassTest : NSObject // classes always begin w/capital letters.

 - (NSString *)returnTestString; 

 @end

You want to call that?

 ClassTest *ct = [[ClassTest alloc] init];
 [ct returnTestString];
