How to print Boolean flag in NSLog?

Question

Is there a way to print value of Boolean flag in NSLog?

Answer 1

Apple's FixIt supplied %hhd, which correctly gave me the value of my BOOL.

Answer 2

Note that in Swift, you can just do

let testBool: Bool = true
NSLog("testBool = %@", testBool.description)

This will log testBool = true

Answer 3

We can check by Four ways

The first way is

BOOL flagWayOne = TRUE; 
NSLog(@"The flagWayOne result is - %@",flagWayOne ? @"TRUE":@"FALSE");

The second way is

BOOL flagWayTwo = YES; 
NSLog(@"The flagWayTwo result is - %@",flagWayTwo ? @"YES":@"NO");

The third way is

BOOL flagWayThree = 1;
NSLog(@"The flagWayThree result is - %d",flagWayThree ? 1:0);

The fourth way is

BOOL flagWayFour = FALSE; // You can set YES or NO here.Because TRUE = YES,FALSE = NO and also 1 is equal to YES,TRUE and 0 is equal to FALSE,NO whatever you want set here.
NSLog(@"The flagWayFour result is - %s",flagWayFour ? YES:NO);

Answer 4

Here is how you can do it:

BOOL flag = NO;
NSLog(flag ? @"YES" : @"NO");

Answer 5

Here's how I do it:

BOOL flag = YES;
NSLog(flag ? @"Yes" : @"No");

?: is the ternary conditional operator of the form:

condition ? result_if_true : result_if_false

Substitute actual log strings accordingly where appropriate.

Answer 6

//assuming b is BOOL. ternary operator helps us in any language.
NSLog(@"result is :%@",((b==YES)?@"YES":@"NO"));
