1、首先让前端的同事打一个包（index.html,static文件包含css、资源文件、js等）导入项目；
:warning: 注意：
把index.html放入项目根目录下，command+n创建一个资源文件.bundle，资源文件里也的包含一份 index.html
下面开始代码：
懒加载WKWebView
引入#import <WebKit/WebKit.h> #import <WebKit/WKWebView.h>
继承 WKNavigationDelegate,WKUIDelegate,
- (WKWebView *)wkWebView{ if (!_wkWebView) { //设置网页的配置文件 WKWebViewConfiguration * Configuration = [[WKWebViewConfiguration alloc]init]; //允许视频播放 if (@available(iOS 9.0, *)) { Configuration.allowsAirPlayForMediaPlayback = YES; } else { // Fallback on earlier versions } // 允许在线播放 Configuration.allowsInlineMediaPlayback = YES; // 允许可以与网页交互，选择视图 Configuration.selectionGranularity = YES; // 关于 WKWebView 无法跳转新页面 设置 Configuration.preferences.javaScriptCanOpenWindowsAutomatically = YES; // web内容处理池 Configuration.processPool = [[WKProcessPool alloc] init]; //自定义配置,一般用于 js调用oc方法(OC拦截URL中的数据做自定义操作) WKUserContentController * UserContentController = [[WKUserContentController alloc]init]; // 添加消息处理，注意：self指代的对象需要遵守WKScriptMessageHandler协议，结束时需要移除 [UserContentController addScriptMessageHandler:self name:@"download"];//DownloadPolicy // 是否支持记忆读取 Configuration.suppressesIncrementalRendering = YES; // 允许用户更改网页的设置 Configuration.userContentController = UserContentController; _wkWebView = [[WKWebView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width, kIs_iPhoneX? self.view.frame.size.height-34:self.view.frame.size.height) configuration:Configuration]; _wkWebView.backgroundColor = [UIColor colorWithRed:240.0/255 green:240.0/255 blue:240.0/255 alpha:1.0]; // 设置代理 _wkWebView.navigationDelegate = self; _wkWebView.UIDelegate = self; // 垂直滚动 [_wkWebView.scrollView setShowsVerticalScrollIndicator:NO]; _wkWebView.scrollView.contentSize = CGSizeMake(self.view.frame.size.width, kIs_iPhoneX? self.view.frame.size.height-34:self.view.frame.size.height); //开启手势触摸 _wkWebView.allowsBackForwardNavigationGestures = YES; // 设置 可以前进 和 后退 //适应你设定的尺寸 [_wkWebView sizeToFit]; [self.view addSubview:_wkWebView]; } return _wkWebView; }
iOS 9 以后和 iOS 8 之前 加载方法不一样，做区分
- (void)viewDidLoad { [super viewDidLoad]; NSFileManager *fileManager = [NSFileManager defaultManager]; NSArray *array1 = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *matPath1 = [[array1 objectAtIndex:0] stringByAppendingPathComponent:@"QueHTML"];; if (![fileManager fileExistsAtPath:matPath1]) { NSString *matString = [[NSBundle mainBundle] pathForResource:@"QueHTML" ofType:@"bundle"]; dispatch_async(dispatch_get_global_queue(0, 0), ^{ [fileManager removeItemAtPath:matPath1 error:nil]; [fileManager copyItemAtPath:matString toPath:matPath1 error:nil]; dispatch_async(dispatch_get_main_queue(), ^{ NSLog(@"创建完了"); if ([[[UIDevice currentDevice] systemVersion] floatValue] < 9.0) { [self ios8Load]; } else{ [self ios9Load]; } }); }); } else{ if ([[[UIDevice currentDevice] systemVersion] floatValue] <9.0) { [self ios8Load]; } else{ [self ios9Load]; } } } - (void)ios8Load { NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *path = [paths objectAtIndex:0]; NSString *basePath = [NSString stringWithFormat:@"%@/%@",path,@"QueHTML/"]; [self.wkWebView loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:[NSTemporaryDirectory() stringByAppendingPathComponent:[NSString stringWithFormat:@"www/QueHTML/index.html"]]]]]; } - (void)ios9Load { NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); NSString *path = [paths objectAtIndex:0]; NSString *basePath = [NSString stringWithFormat:@"%@/%@",path,@"QueHTML/"]; NSString *htmlPath = [NSString stringWithFormat:@"%@/%@",path,@"QueHTML/index.html"]; NSURL *fileURL = [NSURL fileURLWithPath:htmlPath]; if (@available(iOS 9.0, *)) { [self.wkWebView loadFileURL:fileURL allowingReadAccessToURL:[NSURL fileURLWithPath:basePath isDirectory:YES]]; } }
实现代理方法
// 接收到服务器跳转请求之后调用 - (void)webView:(WKWebView *)webView didReceiveServerRedirectForProvisionalNavigation:(WKNavigation *)navigation{ NSLog(@"接收到服务器跳转请求----%@",navigation); } // 在收到响应后，决定是否跳转 - (void)webView:(WKWebView *)webView decidePolicyForNavigationResponse:(WKNavigationResponse *)navigationResponse decisionHandler:(void (^)(WKNavigationResponsePolicy))decisionHandler{ NSLog(@"在收到响应后，决定是否跳转---%@",navigationResponse.response.URL.absoluteString); //允许跳转 decisionHandler(WKNavigationResponsePolicyAllow); //不允许跳转 //decisionHandler(WKNavigationResponsePolicyCancel); } // 在发送请求之前，决定是否跳转 - (void)webView:(WKWebView *)webView decidePolicyForNavigationAction:(WKNavigationAction *)navigationAction decisionHandler:(void (^)(WKNavigationActionPolicy))decisionHandler{ NSLog(@"在发送请求之前，决定是否跳转---%@",navigationAction.request.URL.absoluteString); //允许跳转 decisionHandler(WKNavigationActionPolicyAllow); //不允许跳转 //decisionHandler(WKNavigationActionPolicyCancel); } #pragma mark - WKNavigationDelegate // 页面开始加载时调用 - (void)webView:(WKWebView *)webView didStartProvisionalNavigation:(WKNavigation *)navigation{ NSLog(@"页面开始加载"); } // 当内容开始返回时调用 - (void)webView:(WKWebView *)webView didCommitNavigation:(WKNavigation *)navigation{ NSLog(@"内容开始返回"); } // 页面加载完成之后调用 - (void)webView:(WKWebView *)webView didFinishNavigation:(WKNavigation *)navigation{ NSLog(@"页面加载完成"); } // 页面加载失败时调用 - (void)webView:(WKWebView *)webView didFailProvisionalNavigation:(WKNavigation *)navigation{ NSLog(@"页面加载失败"); }
如果是https访问需加上一下代码
