Instance Methods and Class Methods in Objective-C is very similar to the same concepts implemented in other object oriented programming languages.
Instance methods are the usual methods, and we always need some object(s) to call those specific methods. When we declare and implement them, we always start with the - (minus sign). The syntax for calling an instance method is:
[objectName instanceMethodName];
For class methods we do not need any object created in our program in order to call them.
They always start with the + (plus sign). The syntax for calling a class method is:
[ClassName classMethodName]; Instance Methods and Class Methods in Objective-C](https://i.ytimg.com/vi/sjFLaJD_cgA/mqdefault.jpg)
