#19 Zero lines counted int Obj c code

[Andrey Manov]

I have a file TestClass.m written in Objective-C with following contents:

#import "TestClass.h"

NSString *const ADDITION_SFX = @"123321";

@implementation TestClass

+ (NSString*) testMethod:(NSString*)originalString
{
    NSString *resultString = nil;
    if (originalString != nil && originalString.length > 0) {
        resultString = [NSString stringWithFormat:@"%@ + %@", originalString, ADDITION_SFX];
    } else {
        resultString = @"";
    }
    return resultString;
}

@end

When I count lines for it, I'm having zero output:

andreys-imac:TestProject andreymanov$ sloccount TestClass.m 
Have a non-directory at the top, so creating directory top_dir
Adding /Users/andreymanov/Documents/projects/iOSWorkspace/TestProject/TestClass.m to top_dir

SLOC    Directory   SLOC-by-Language (Sorted)
0       top_dir         (none)
SLOC total is zero, no further analysis performed.

Though when I'm adding one more method in the file, it starts working correct.

TestClass2.m

#import "TestClass.h"

NSString *const ADDITION_SFX = @"123321";

@implementation TestClass

+ (void) initialize {
}

+ (NSString*) testMethod:(NSString*)originalString
{
    NSString *resultString = nil;
    if (originalString != nil && originalString.length > 0) {
        resultString = [NSString stringWithFormat:@"%@ + %@", originalString, ADDITION_SFX];
    } else {
        resultString = @"";
    }
    return resultString;
}

@end

Output:
