![Language - Objective-C
LEARNING TO LOVE [ ]
• The Objective-C language is a simple computer language
designed to enable sophisticated object-oriented programming.
• Knowing or having an understanding of C will help you
understand this language
• It is a C superset based and built on Smalltalk

![Syntax
YOU’LL GET USED TO IT
• NSString *string = [NSString string]
• [NSString stringWithFormat:[prefs format]];
• return [object name] (same as) return object.name
• More as we dive into the code
