By adding this line, it will detect the properties mentioned in the Product.h file. You can create an instance in Objective C in 3 different ways:Īdd the line #import "Product.h" in main.m file. Here we will be creating instance(object) of the Product class. (void)setProductName:(NSString *)prodName Return _productID // retrieving the value of the property _productID = productID // assigning the value of NewName to the original property Here we will be assigning the value of NewName to that of the original property name and also retrieving the property values. Setters are used to change the value of the property and are denoted as follows: -(return type)setName:(type)NewName.Getters are used to retrieve the value of the property and are denoted as follows: -(type)name.(void)setProductName:(NSString The next step will be to create accessors i.e getters and setters for the properties. Declaring getters and setters for the above properties Now, open Product.h file and let's declare some properties inside the block as shown below. In the Header file, we declare properties and functions whereas in the. h extension is the Header file and the other one with. Now, you can see 2 new files added in your Project Navigator with the extensions.Also, make sure the subclass was selected as NSObject while entering Class Name. Select Cocoa Class -> Next -> Enter the Class Name as 'Product' -> Next -> Create. To add new files, right-click on your Project and select New File.This file is similar to the main function in C programming. Now, in the Project Navigator, you will see a 'main' file.Select the desired location and save your project.Name your project and select the language as Objective C. We will be displaying the output in the Xcode console.Ĭlick on Next. Open XCode and create a new project by selecting macOS -> Command Line Terminal as shown in the below image. So, let's get familiar with Objective C by implementing a simple example. It is one of the first object-oriented programming languages. Objective C is a programming language used to develop iOS/Mac applications. This article explains creating Class, Instance/Object, and Accessors in Objective C. This article is for beginners who want to learn and develop iOS apps in Objective C.
