Objective-C formatting string for boolean?

Question

What formatter is used for boolean values?

EDIT:

Example: NSLog(@\" ??\", BOOL_VAL);, what is ?? ?

Answer 1

Just add the below function and pass it the BOOL value and method will return back the NSString

- (NSString *)boolValueToString:(BOOL)theBool {
    if (theBool == 0)
        return @"NO"; // can change to No, NOOOOO, etc
    else
        return @"YES"; // can change to YEAH, Yes, YESSSSS etc
}

Answer 2

I believe the easiest way to do this is:

NSLog(@" %@", @(BOOL_VAL));

@(expression)

Dynamically evaluates the boxed expression and returns the appropriate object literal based on its value (i.e. NSString for const char*, NSNumber for int, etc.).

Answer 3

Use the integer formatter %d, which will print either 0 or 1:

NSLog(@"%d", myBool);
