How to print Boolean flag in NSLog?

Question

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

Answer 1

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 2

%d, 0 is FALSE, 1 is TRUE.

BOOL b;  NSLog(@"Bool value: %d",b); 

or

NSLog(@"bool %s", b ? "true" : "false"); 

On the bases of data type %@ changes as follows

For Strings you use %@ For int  you use %i For float and double you use %f
