32 | - (void)webViewDidFinishLoad:(VDWebView *)webView; 33 | - (void)webView:(VDWebView *)webView didFailLoadWithError:(NSError *)error; 34 | - (BOOL)webView:(VDWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType; 35 | ``` 36 | * 对`WKUIDelegate`和`WKScriptMessageHandler`代理的合并 37 | 38 | ``` 39 | /** 40 | JS调原生代理方法(注册了过的方法将全部通过此方法回调) 41 | */ 42 | - (void)webView:(VDWebView *)webView didReceiveScriptMessage:(WKScriptMessage *)message; 43 | 44 | /** 45 | JS弹框拦截方法--如果需要自定义弹框建议声明此方法 46 | */ 47 | - (void)webView:(VDWebView *)webView showAlertWithType:(VDJSAlertType)type title:(NSString *)title content:(NSString *)content completionHandler:(void (^)(id))completionHandler; 48 | ``` 49 | 50 | #### 新增了哪些属性和方法 51 | 52 | 详情可见`VDWebViewProtocol` 53 | 54 | ``` 55 | ///预估网页加载进度 56 | @property (nonatomic, readonly) CGFloat estimatedProgress; 57 | // 是否显示进度条 默认不显示 58 | @property (nonatomic, assign) BOOL isShowProgressBar; 59 | ///进度条 60 | @property (nonatomic, strong) UIView *progressBar; 61 | /** 62 | web页面加载完毕后的内容高度(在页面加载完成后获取) 63 | */ 64 | @property (nonatomic, readonly) CGFloat *contentHeight; 65 | /// 是否启用js调用原生弹框 默认为NO 禁止(默认加载弹框在根试图) 66 | @property (nonatomic, assign) BOOL enableAllAlert;

73 | - (void)gobackWithStep:(NSInteger)step; 74 | 75 | ``` 76 | 77 | ## JS调用OC方法的绑定 78 | 79 | 在使用`WKWebView`时我们需要调用`WKWebView`内`configuration`中的`userContentController`所属类`WKUserContentController`提供的实例方法进行注册，具体方法如下: 80 | 81 | ``` 82 | - (void)addScriptMessageHandler:(id )scriptMessageHandler name:(NSString *)name; 83 | ``` 84 | 对应的注销方法为: 85 | 86 | ``` 87 | - (void)removeScriptMessageHandlerForName:(NSString *)name; 88 | ``` 89 | 90 | #### 已知的循环引用问题 91 | 92 | 在使用`addScriptMessageHandler:name:`方法注册时传入的这个handler被循环引用，如果不调用对应的注销方法就会导致handler这个对象无法被释放，如果你这个handler传入是webView所在的控制器，那么你就要在销毁这个控制器前注销掉你注册的方法. 93 | 94 | tip： 如何知道控制器有没有被释放，重写dealloc()，没走此方法说明未被释放 95 | 96 | #### VDWebView是如何解决循环引用问题 97 | 98 | 简要分析可分为下面三步 99 | 100 | * 使用`VDScripMessageHandler`作为注册的handler 101 | * 继承协议`WKScriptMessageHandler` 102 | * 提供target-action回调方式 103 | * 保存注册记录 104 | * 在`VDWebView`的`dealloc()`方法中获取注册记录并注销 105 | 106 | 这些做的好处在于你在使用VDWebView时无需自己去一个个手动注销了(如果你注册的方法多的话那就是噩梦了) 107 | 108 | #### VDWebView是如何进行方法的注册和回调的 109 | 110 | * 方法的注册 111 | 112 | ``` 113 | - (void)addScriptMessageHandler:(id)scriptMessageHandler name:(NSString *)name; 114 | ``` 115 | 116 | * JS调用说明 117 | 118 | ``` 119 | // 没效果可使用try-catch 120 | window.webkit.messageHandlers.#OC方法名#.postMessage(#参数#) 121 | 122 | ``` 123 | 124 | 回调方式分两种：delegate和target-action; 两种方式只能存一，优先delegate 125 | 126 | * delegate方式，只需在控制器中声明`VDWebViewDelegate`中的方法 127 | 128 | ``` 129 | - (void)webView:(VDWebView *)webView didReceiveScriptMessage:(WKScriptMessage *)message; 130 | ``` 131 | * target-action方式 132 | * 不能声明上述的代理方法 133 | * 在控制器(方法注册传入的scriptMessageHandler)中声明同名的OC方法 134 | 135 | #### 为什么要增加target-action的方式 136 | > target-action：目标－动作模式,拜C语言所赐,更是灵活很多,编译期没有任何检查,都是运行时的绑定 137 | 138 | * 在`VDWebView`中就是通过`NSSelectorFromString()`动态加载方法，再通过`NSMethodSignature`和`NSInvocation`进行方法的签名和调用 139 | * 这样就可以充分的体现JS调用对应的OC方法和一对一更加清晰和方便处理 140 | 141 | ## JS的调用和注入 142 | 143 | 可通过两种方式进行JS方法的调用，推荐第一种 144 | 145 | * WKWebView的同名方法 146 | 147 | ``` 148 | - (void)evaluateJavaScript:(NSString *)javaScriptString completionHandler:(void (^)(id, NSError *))completionHandler; 149 | 150 | ``` 151 | * UIWebView的同名方法（不建议使用这个办法，因为会在内部等待执行结果） 152 | 153 | ``` 154 | - (NSString *)stringByEvaluatingJavaScriptFromString:(NSString *)javaScriptString; 155 | ``` 156 | 157 | 脚本的注入和移除 158 | 159 | ``` 160 | /** 161 | 注入脚本(js...) 162 | */ 163 | - (void)addUserScriptWithSource:(NSString *)source injectionTime:(WKUserScriptInjectionTime)injectionTime forMainFrameOnly:(BOOL)mainFrameOnly; 164 | 165 | /** 166 | 移除所有注入的脚本 167 | */ 168 | - (void)removeAllUserScripts; 169 | ``` 170 | ## cookie的处理(待优化)`VDWebViewCookiesProtocol` 171 | 172 | #### 提供cookie的共享 173 | 由于WKWebView的cookie是和NSHTTPCookieStorage不共享，这就造成使用WKWebView打开的web页面无法获取到通过原生请求登录的cookie，当然其它解决方案有很多种，比如 174 | * 通过URL的拼接把登录信息传递过去 175 | * 通过js方法传值 176 | 177 | 但是用了VDWebView就不需要考虑cookie的问题了，因为它已经默认把cookie带过去了，当然你也可以手动去关闭 178 | 179 | ``` 180 | /** 181 | 不同步NSHTTPCookieStorage存储的cookies 默认同步:NO 182 | 同步NSHTTPCookieStorage中的cookie到WKWebView中，有可能会污染WKWebView中的cookie管理 183 | */ 184 | @property (nonatomic, assign)BOOL httpCookiesDisable; 185 | ``` 186 | 187 | #### 对cookie的操作 188 | ``` 189 | /** 190 | 设置cookie 191 | */ 192 | - (void)setCookieWithKey:(NSString *)key value:(NSString *)value expires:(NSTimeInterval)expires domain:(NSString *)domain; 193 | - (void)setCookies:(NSString *)cookies; 194 | /** 195 | 获取cookie 196 | */ 197 | - (NSArray *)getCookies; 198 | ``` 199 | 200 | ## iOS和Android通用的JS与OC交互方法`VDWebViewJSBridge` 201 | 202 | #### 关于使用方法 203 | 204 | 你只需要调用`VDWebView`继承的协议`VDWebViewProtocol`所提供的初始化方法`bridgeInitialized`即可 205 | 206 | ``` 207 | // 调用初始化 在webView的控制器中实现同名方法 208 | self.webView.delegate = self; 209 | [self.webView bridgeInitialized]; 210 | ``` 211 | 212 | ### js调用原生 213 | 214 | 与对应的js配套使用，此方案适用于iOS和Android对应的js文件如下 215 | 216 | [VDJSWebBridge.js传送门](https://github.com/VolientDuan/VDWebView/blob/master/VDWebView/Source/html/static/js/VDJSWebBridge.js) 217 | ``` 218 | // 在js中直接调用VDJSWebBridge.js提供的方法,详情请查看js 219 | // methodName为控制器中声明的方法名，params为json字符串 220 | vd_jsBridge(methodName, params) 221 | ``` 222 | #### 从JS方法触发开始整个调用的过程如下 223 | 1. 对params进行了base64编码 224 | 2. 最终的请求URL格式为 vdjsbridge://methodName?params=base64(params) 225 | 3. APP拦截请求，解析URL匹配scheme(vdjsbridge)，获取方法名，base64解码和json转对象获取参数值 226 | 4. 接受到第三步获取的方法名和参数后通过Target-Action方法调用对应的方法 227 | 228 | ### OC调用JS方法 229 | 230 | ``` 231 | // JS 方法 232 | function jsMethod(param1, param2, param3) { 233 | alert("使用jsBridge调用js方法成功参数为："+param1+param2+param3) 234 | return "success"; 235 | } 236 | 237 | // OC调用JS方法 238 | [self.webView.bridge executeJsMethod:@"jsMethod" params:@[@"1",@"2",@"3"] completionHandler:^(id result, NSError *error) { 239 | NSLog(@"\njs方法执行h结果回调：%@\n错误信息:%@",result,error); 240 | }]; 241 | 242 | ``` 243 | 244 | ## 后续版本思考和设计中 245 | * ~~cookie的处理~~ 246 | * ~~拦截webView内部请求通过自定义URL的方式进行JS交互~~ 247 | * APP和web资源共享问题：比如图片 248 | 249 | -------------------------------------------------------------------------------- /VDWebView.podspec: -------------------------------------------------------------------------------- 1 | Pod::Spec.new do |s| 2 | s.name = 'VDWebView' 3 | s.version = '1.0.3' 4 | s.summary = 'a great webView for iOS' 5 | s.homepage = 'https://github.com/VolientDuan/VDWebView' 6 | s.license = 'MIT' 7 | s.authors = { 'volientDuan' => 'volientduan@163.com' } 8 | s.platform = :ios, '8.0' 9 | s.framework = "UIKit" 10 | s.source = { :git => 'https://github.com/VolientDuan/VDWebView.git', :tag => s.version } 11 | s.requires_arc = true 12 | s.source_files = 'VDWebView/VDWebView/**.{h,m}' 13 | end 14 | -------------------------------------------------------------------------------- /VDWebView.xcodeproj/project.pbxproj: -------------------------------------------------------------------------------- 1 | // !$*UTF8*$! 2 | { 3 | archiveVersion = 1;
