![]() ![]() #import ”ViewController.h ” : This line is to import our.This is also called as an implementation file. Now go to viewController.m and describe the method which is defined in. : This indicates that our interface part is over.showMessage is an method name (we can give any name to this method). When we want to perform some action on tapping a button, we use IBAction. – (IBAction)showMessage : This is a method which we created manually.It inherits UIViewController class, which is used to handle the flow of our screen or view. ![]() ViewController : UIViewController – This is an interface for class ViewController.h.doesn’t need to be imported manually now. For example: UIViewController.h, UIView.h or UIButton.h. After importing this header file, we don’t have to import other UIHeader manually. The UIKit header file imports all other header files available in UIKit framework. UIKit is a framework which contains all the inbuilt library file for UI part. #import – This is a header file which we are importing in our code.The showMessage method will use the UIAlertview function to display a pop-up in our example application. Int (nonatomic, strong) NSString *recipeName If we want to declare variables, then it is declared under the braces of interface, and property and methods are defined outside the braces.įor example: ViewController : UIViewController h file is an interface file of our project in which we declare the property and method. On the left panel, click on viewcontroller.h, and write the following method in it. Now, it is time to write the code for our app. In this example, we’ll name this button as “Hello”.įor this basic example, the UI part is over. On the right side panel, there are a lot of components (button, label, text field, etc).ĭrag and drop button component from right side Panel. Currently, this is an empty view controller. This is where you will design the UI layout for your app. Story board provides the view to your application. Under “MyFirstApp”, select “Main.storyboard” from left side panel. The left side panel contains the declaration of classes. This will launch the Xcode editor with the new project as shown below. Next, this will ask you to save your project in a directory. In the Devices drop-down list, select iPhone. In this screen, you’ll specify: Production Name, Organization Name, Company Identifer, Bundle Identifier, Class Prefix, and Devices. Now specify the details about this new project. This provides a view controller to manage the view, and a storyboard or nib file that contains the view. As it shows in the description, this template provides a starting point for an application that uses a single view. iOS is for touch devices (iPhone, iPad, iPod, etc.) and OS X is for desktop devices.įor iOS Application, it shows 8 different templates that you can use.įor this example, we will choose single view application. On the left side, under “iOS”, click on Application. Xcode provide various templates that you can use when you are creating a new project. Since we are creating our first iPhone app, click on “Create a new Xcode project”. In right side panel of this screen, you’ll see your existing projects that you can open. When you launch Xcode, it will start the “welcome to Xcode” dialogue. This simulator is provided as an extension as part of Xcode IED itself. iOS simulator acts as a virtual iOS device. Once you write the app code, you can run the app in a simulator to see how the app will behave on a real iPhone or iPad. If you have some knowledge of C Programming or C++ Programming, it is very easy to get started on Objective C. To create an iPhone app you need to understand Objective C. Xcode is an IDE used for iOS application development. If you are a newbie to iPhone app development, this tutorial will guide you through step-by-step on how to create your first iPhone app. Objective C is an extension of C Programming Language and it’s an Object Oriented Language.įor creating an iPhone app you need two things: 1) Apple’s Mac Laptop or Desktop 2) Xcode for IDE. Apple iOS apps are written in Objective C language.
