Objective-C Language Logging NSLog and BOOL type
Example
There is no format specifier to print boolean type using NSLog. One way to print boolean value is to convert it to a string.
BOOL boolValue = YES;
NSLog(@"Bool value %@", boolValue ? @"YES" : @"NO");
Output:
2016-07-30 22:53:18.269 Test[4445:64129] Bool value YES
Another way to print boolean value is to cast it to integer, achieving a binary output (1=yes, 0=no).
BOOL boolValue = YES;
NSLog(@"Bool value %i", boolValue);
Output:
2016-07-30 22:53:18.269 Test[4445:64129] Bool value 1
