18 | } 19 | 20 | if (isiOS) { 21 | window.webkit.messageHandlers.onSayHello.postMessage('Hello'); 22 | } 23 | 24 | // 现在 iOS使用CXYWebScript后, H5无需引入任何库，iOS和Android统一调用： 25 | window.App?.onSayHello('Hello') 26 | ``` 27 | 28 | > Tip1: 以上 window.App 是可以自定义的，如 window.CXY 29 | > 30 | > Tip2: 判断当前环境是客户端还是其他H5端，可直接使用 if (window.App) 就行 31 | 32 | 33 | 34 | ##### iOS 端的简化 35 | 36 | ```objective-c 37 | // 以前 38 | CXYWeakScriptMsgHander *weakSelf = [[CXYWeakScriptMsgHander alloc] initWithHandler:self];

80 | 81 | ``` 82 | 83 | 84 | 85 | ### [CXYWebScript](https://github.com/iHongRen/CXYWebScript) 有以下特点： 86 | 87 | - H5 在调用原生 App 方法是时，不需要区分是 Android 还是 iOS 环境 88 | - 支持使用 block，async-block 和 target-action 方式注册 js 方法 89 | - 支持原生 App 传递返回值给 H5 (限字符串类型或 nil ) 90 | - 支持 OC 与 Swift， **iOS 10+** 91 | - 不到 **200** 行代码 92 | 93 | 94 | 95 | 96 | 97 | ### 如何使用 98 | 99 | #### H5 端 JS代码，详细见 [Demo.html](./CXYWebScript/Demo.html) 100 | 101 | ```js 102 | // 调用原生App方法，并能接收App端方法的返回值 103 | function onBtn1Click() { 104 | if (window.App) { 105 | // 接收 App 端的返回值 106 | const ret = window.App.onSayHello('Hello') 107 | console.log(ret) 108 | } 109 | } 110 | 111 | // 传递多个参数给App端 112 | function onBtn2Click() { 113 | const imgs = [ 114 | 'https://www.baidu.com/img/1.png', 115 | 'https://www.baidu.com/img/2.png', 116 | 'https://www.baidu.com/img/3.png'] 117 | 118 | window.App?.onPreviewImages(imgs, 1) 119 | } 120 | 121 | // App 端调用此方法，修改body背景 122 | function onChangeTheme(theme) { 123 | document.body.style.backgroundColor = theme 124 | return '修改成功' // 返回一个字符串给App端 125 | } 126 | ``` 127 | 128 | #### App 端 OC代码，详细见 [ViewController.m](./CXYWebScript/CXYWebScript/ViewController.m)： 129 | 130 | ```objective-c 131 | #import "CXYWebScript.h" 132 | 133 | - (void)setupWebScript { 134 | // 初始化 CXYWebScript 135 | self.webScript = [[CXYWebScript alloc] initWithWebView:self.webView];

\ 252 | }; \ 253 | } \ 254 | });" 255 | 256 | WKUserScript *script = [[WKUserScript alloc] initWithSource:js injectionTime (WKUserScriptInjectionTimeAtDocumentStart) forMainFrameOnly:NO]; 257 | [self.webView.configuration.userContentController addUserScript:script]; 258 | ``` 259 | 260 | > 提示: 261 | > 262 | > 使用` window.webkit.messageHandlers[name].postMessage(args);` 亦可，只是后续实现略有不同。 263 | > 264 | > 问：为什么选用window.prompt方式呢？ 265 | > 266 | > 答：因为它能直接同步返回值。 267 | 268 | 269 | 270 | **Proxy** 的作用是拦截对 `window.App` 对象属性的访问。重写` window.App` 的 `get` 方法，当访问它的属性(name)时，会返回一个**匿名函数** ； 271 | 272 | - 该函数的参数是可变的，类数组 273 | 274 | - 该函数返回了` window.prompt(window.App.属性名, args的json字符串数组);` 275 | 276 | 那么当 H5 端 js 调用： 277 | 278 | ```js 279 | window.App.onSayHello('Hello') 等价于 => window.prompt('onSayHello',\"['Hello']\"); 280 | ``` 281 | 282 | 283 | 284 | 2、而在 iOS H5 里调用 `window.prompt` 会执行 WKWebView.UIDelegate 的方法： 285 | 286 | ```objective-c 287 | - (void)webView:(WKWebView *)webView 288 | runJavaScriptTextInputPanelWithPrompt:(NSString *)prompt 289 | defaultText:(nullable NSString *)defaultText 290 | initiatedByFrame:(WKFrameInfo *)frame 291 | completionHandler:(void (^)(NSString * _Nullable result))completionHandler; 292 | 293 | // 调用completionHandler后，能同步返回值给H5端。 294 | completionHandler('返回值') 295 | ``` 296 | 297 | 其中的两个参数分别对应**方法名**和**参数列表JSON数组**： 298 | 299 | ``` 300 | (NSString *)prompt => 'onSayHello' 301 | (nullable NSString *)defaultText => '[\'Hello\']' 302 | ``` 303 | 304 | 305 | 306 | 3、对于 **target-action** 方式，根据方法名得到对应的 `SEL`，使用`NSInvocation`类，可以构造一个表示方法调用的对象，包括方法选择器、目标对象、参数和返回值。可以处理具有多个参数的方法调用。 307 | 308 | ```objective-c 309 | self.scriptMap = {@"onSayHello": NSStringFromSelector(onSayHello:)} 310 | NSString *selString = self.scriptMap[prompt]; 311 | SEL sel = NSSelectorFromString(selString); 312 | NSArray *args = [self arrayWithJSON:defaultText]; 313 | 314 | NSMethodSignature *signature = [self methodSignatureForSelector:aSelector]; 315 | NSInvocation *invocation = [NSInvocation invocationWithMethodSignature:signature]; 316 | [invocation setTarget:self]; 317 | [invocation setSelector:aSelector]; 318 | ... 详细见源码 319 | ``` 320 | 321 | 322 | 323 | 4、对于 **block**、**async-block** 方式，根据方法名找到对应的 block，直接执行 block 就行： 324 | 325 | ```objective-c 326 | // self.blockMap = {@"onSayHello": CXYBlock} 327 | CXYBlock block = self.blockMap[prompt]; 328 | NSArray *args = [self arrayWithJSON:defaultText]; 329 | block(args); 330 | ``` 331 | -------------------------------------------------------------------------------- /screenshot.png: -------------------------------------------------------------------------------- https://raw.githubusercontent.com/iHongRen/CXYWebScript/20f07c354ac8991b989c6c2b2a13d065fe3d207c/screenshot.png --------------------------------------------------------------------------------
