What is Boolean in Objective C?

What is Boolean in Objective C?

Objective-C defines the BOOL type to encode truth values. By convention, we use the BOOL type for Boolean parameters, properties, and instance variables and use YES and NO when representing literal Boolean values. Because NULL and nil zero values, they evaluate to “false” in conditional expressions.

How do I print a Boolean in Objective-C?

Objective-C Language Logging NSLog and BOOL type There is no format specifier to print boolean type using NSLog. One way to print boolean value is to convert it to a string. Another way to print boolean value is to cast it to integer, achieving a binary output (1=yes, 0=no).

What is the use of nscfboolean?
