## Requirements

iOS 6.0+

## Installation

HWJavaScriptBridge is available through [CocoaPods](https://cocoapods.org). To install

it, simply add the following line to your Podfile:

```ruby

pod 'HWJavaScriptBridge'

```

## Usage

### For  WKWebView

```objective-c

 HWWebViewJavaScriptBridge *bridge = [[HWWebViewJavaScriptBridge alloc] initWithWebView:self.webView];

    self.bridge = bridge;

    [bridge registerHandler:@"invoke" handler:^(id  _Nonnull data, HWJBResponseCallback  _Nonnull responseCallback) {

        NSDictionary *clientData = @{

            @"code":@(0),

            @"msg":@"success",

            @"data":@{@"company":@"tencent"}

        };

        responseCallback(clientData);

    }];

```

```objective-c

 [self.bridge callHandler:@"dispatchEvent" data:@{@"func": @"preRender"} responseCallback:^(id  _Nonnull responseData) {

        NSLog(@"[preRender] callback =%@", responseData);

    }];

```

### For  JSContext

```objective-c

    JSVirtualMachine *vm = [[JSVirtualMachine alloc] init];

    JSContext *ctx = [[JSContext alloc] initWithVirtualMachine:vm];

    self.ctx  = ctx;

    HWJSContextJavaScriptBridge *bridge = [[HWJSContextJavaScriptBridge alloc] initWithJSContext:ctx];

    self.bridge = bridge;

    

    // 监听JS调用的postMessage方法

    [bridge registerHandler:@"invoke" handler:^(id  _Nonnull data, HWJBResponseCallback  _Nonnull responseCallback) {

        NSDictionary *clientData = @{

            @"code":@(0),

            @"msg":@"success",

            @"data":@{@"company":@"tencent"}

        };

        responseCallback(clientData);

    }];

```

```objective-c

 // 客户端主动调用JS，并得到JS的回应

    NSDictionary *data = @{

        @"func":@"preRender",

        @"params":@{

            @"url":@"https://m.film.qq.com"

        }

    };

    [self.bridge callHandler:@"dispatchEvent" data:data responseCallback:^(id responseData) {

        NSLog(@"[preRender] recieve callback data=%@", responseData);

    }];

```
