Official iOS Dev Tutorial: Chinese Edition30

This guide is an unofficial translation of Apple's official iOS Development Tutorial. It is intended to help Chinese developers who are new to iOS development get started with building their first iOS apps.

Getting Started

To get started with iOS development, you will need the following:
A Mac with macOS 10.15 or later
Xcode 11 or later
An Apple Developer account

Once you have these requirements, you can follow the steps in this tutorial to create your first iOS app.

Creating a New Project

To create a new iOS app project, open Xcode and click on the "Create a new Xcode project" button. In the "Project Template" section, select the "iOS" tab and then choose the "Application" template. Enter a name for your project and click on the "Create" button.

Adding a View Controller

A view controller is a class that manages the user interface of a screen in your app. To add a view controller to your project, click on the "File" menu and select "New" -> "File...". In the "New File" dialog box, select the "Objective-C class" template and enter a name for your view controller class. Click on the "Create" button to add the new class to your project.

Editing the Interface Builder

Interface Builder is a tool in Xcode that allows you to create and edit the user interface of your app. To open Interface Builder, click on the "Interface Builder" button in the Xcode toolbar. The Interface Builder window will show a graphical representation of the user interface of your app. You can add and rearrange elements on the screen by dragging and dropping them from the "Library" pane.

Adding Code to the View Controller

Once you have created the user interface for your app, you need to add code to the view controller to make it work. To do this, open the ".m" file for your view controller class in the Xcode editor. In the ".m" file, you will find the implementation of the methods for your view controller. You can add code to these methods to handle events, update the user interface, and perform other tasks.

Building and Running Your App

Once you have added code to your view controller, you can build and run your app. To do this, click on the "Build" menu and select "Build and Run". Xcode will build your app and launch it on your device or simulator.

Conclusion

This tutorial has covered the basics of iOS development. For more information, you can refer to the Apple documentation or take an iOS development course.
