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

- (void)webView:(WKWebView *)webView didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge completionHandler:(void (^)(NSURLSessionAuthChallengeDisposition disposition, NSURLCredential *credential))completionHandler {  if ([challenge.protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust]) {    if ([challenge previousFailureCount] == 0) {      NSURLCredential *credential = [NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust];      completionHandler(NSURLSessionAuthChallengeUseCredential, credential);    } else {      completionHandler(NSURLSessionAuthChallengeCancelAuthenticationChallenge, nil);    }  } else {   completionHandler(NSURLSessionAuthChallengeCancelAuthenticationChallenge, nil);  }}
