Accessor Methods

• Accessor methods are used to interact with Object Attributes. One can set or get the values on the Object.

• You should always use any provided accessor methods when manipulating another object's attributes. Never reach into an object and change values directly.

• As per Cocoa naming convention Setter methods are named after the attribute they change, preceded by the world “set”. Example setAge, setName setFillColor

• Getter names are simply named after the attribute they return. For example for above setters getter methods will be age,name,fillColor.

• Preceding get with attribute name will actually violate Cocoa naming conventions.
