How to use Vue.js and Objective-C to develop innovative iOS app experiences

Vue.js is a popular JavaScript framework that focuses on building user interfaces. Objective-C is a mainstream programming language for iOS application development. This article will introduce how to use Vue.js and Objective-C together to develop innovative iOS application experiences, and provide code examples.

1. Environment preparation
   First, you need to install and configure the following environment:
2. Node.js: used to run the Vue.js development environment;
3. Xcode: used to write and run Objective-C code;
4. Vue CLI: used to create and manage Vue.js projects.

5. Create Vue.js project
   Open the terminal and install the Vue CLI by running the following command:

   $ npm install -g @vue/cli

   After the installation is complete, you can create a new Vue by running the following command .js project:

   $ vue create my-app

   Enter the project directory:

   $ cd my-app

   Start the development server:

   $ npm run serve

   Now, you can visit http://localhost in the browser :8080 to view Vue.js applications.

6. Integrate Objective-C
   Create a new Objective-C project in Xcode. In your project, you can use Objective-C to write view controllers, data models, and other code that needs to interact with the iOS system.

In Objective-C projects, you can use the WebView component of Vue.js to display Vue.js applications. First, import the WebKit library in the Objective-C project:

@import WebKit;

Create a WebView object:

@property (nonatomic, strong) WKWebView *webView;

Load the URL of the Vue.js application for the WebView:

NSString *urlString = @"http://localhost:8080";
NSURL *url = [NSURL URLWithString:urlString];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[self.webView loadRequest:request];

Place the WebView Add to the view:

[self.view addSubview:self.webView];

4. Implementing interaction between Vue.js and Objective-C
   In a Vue.js application, you can use Vue.js’ vue-bridge Library to realize the interaction between Vue.js and Objective-C. First, install vue-bridge in the Vue.js project:

   $ npm install vue-bridge

   In the Vue.js application, you can use the vue-bridge library callNative method to call Objective-C methods:

   import VueBridge from 'vue-bridge';
   
   // ...
   
   Vue.use(VueBridge);
   
   // ...
   
   this.$bridge.callNative('methodName', { param1: 'value1', param2: 'value2' })
     .then(response => {
    // 处理Objective-C的响应
     })
     .catch(error => {
    // 处理错误
     });

   In Objective-C, you can use

   WKScriptMessageHandler to listen for messages sent by Vue.js applications:

   @interface ViewController () <WKScriptMessageHandler>
   
   // ...

5. (void)userContentController:(WKUserContentController

   )userContentController didReceiveScriptMessage:(WKScriptMessage )message { if ([message.name isEqualToString:@"methodName"]) {
   

    // 处理Vue.js发送的消息

   }

   }
   

   @end

Through the above method, you can achieve two-way communication between Vue.js and Objective-C , thereby achieving innovative iOS application experience.

To sum up, by combining Vue.js and Objective-C, we can develop applications with innovative iOS application experience. Vue.js focuses on building user interfaces, while Objective-C is used for interacting with the iOS system. By properly calling their respective functions, we can build powerful and user-friendly applications.

The code example provided in this article is just a simple method, and can be further adjusted and optimized according to needs in actual development. I hope this article can be helpful to you in developing iOS applications using Vue.js and Objective-C.
