+
+## Classes, Methods & Objects
+
+* Declare an **interface** with the **properties** & **methods**
+
+```objectivec
+// Declare the interface of the class
+@interface MyVehicle : NSObject
+
+// Declare the properties
+@property NSString *vehicleType;
+@property int numberOfWheels;
+
+// Declare the methods
+- (void)startEngine;
+- (void)addWheels:(int)value;
+
+@end
+```
+
+* **Implement** the **class** from the interface
+
+```objectivec
+@implementation MyVehicle : NSObject
+
+// No need to indicate the properties, only define methods
+
+- (void)startEngine {
+    NSLog(@"Engine started");
+}
+
+- (void)addWheels:(int)value {
+    self.numberOfWheels += value;
+}
+
+@end
+```
+
+* **Create an object** of the class & **call** a **method**
+
+To create an instance of a class the **`alloc`** method is called which **allocate memory** for each **property** and **zero** those allocations. Then **`init`** is called, which **initilize the properties** to the **required values**.
+
+```objectivec
+// Something like this:
+MyVehicle *newVehicle = [[MyVehicle alloc] init];
+
+// Which is usually expressed as:
+MyVehicle *newVehicle = [MyVehicle new];
+
+// To call a method
+// [myClassInstance nameOfTheMethodFirstParam:param1 secondParam:param2]
+[newVehicle addWheels:4];
+```
+
+* **Class methods**
+
+Class methods are defined with the **plus sign** (+) not the hyphen (-) that is used with instance methods. Like the **NSString** class method **`stringWithString`**:
+
+```objectivec
++ (id)stringWithString:(NSString *)aString;
+```
+
+* **Setter** & **Getter** Methods
+
+To **set** & **get** properties, you could do it with a **dot notation** or like if you were **calling a method**:
+
+```objectivec
+// Set
+newVehicle.numberOfWheels = 2;
+[newVehicle setNumberOfWheels:3];
+
+// Get
+NSLog(@"Number of wheels: %i", newVehicle.numberOfWheels);
+NSLog(@"Number of wheels: %i", [newVehicle numberOfWheels]);
+```
+
+* **Instance Variables**
+
+Alternatively to setter & getter methods you can use instance variables. These variables have the same name as the properties but starting with a "\_":
+
+```objectivec
+- (void)makeLongTruck {
+    _numberOfWheels = 10000;
+}
+```
