vue項目iOSWKWebView加載

1、首先讓前端的同事打一個包（index.html,static文件包含css、資源文件、js等）導入項目；

創(chuàng)新互聯(lián)建站-專業(yè)網(wǎng)站定制、快速模板網(wǎng)站建設、高性價比高邑網(wǎng)站開發(fā)、企業(yè)建站全套包干低至880元,成熟完善的模板庫,直接使用。一站式高邑網(wǎng)站制作公司更省心,省錢,快速模板網(wǎng)站建設找我們，業(yè)務覆蓋高邑地區(qū)。費用合理售后完善，10年實體公司更值得信賴。

:warning: 注意：

把index.html放入項目根目錄下，command+n創(chuàng)建一個資源文件.bundle，資源文件里也的包含一份 index.html

vue 項目 iOS WKWebView 加載

下面開始代碼：

懶加載WKWebView

引入#import #import

繼承 WKNavigationDelegate,WKUIDelegate,

- (WKWebView *)wkWebView{
  if (!_wkWebView) {
    //設置網(wǎng)頁的配置文件
    WKWebViewConfiguration * Configuration = [[WKWebViewConfiguration alloc]init];
    //允許視頻播放
    if (@available(iOS 9.0, *)) {
      Configuration.allowsAirPlayForMediaPlayback = YES;
    } else {
      // Fallback on earlier versions
    }
    // 允許在線播放
    Configuration.allowsInlineMediaPlayback = YES;
    // 允許可以與網(wǎng)頁交互，選擇視圖
    Configuration.selectionGranularity = YES;
    // 關于 WKWebView 無法跳轉新頁面 設置
    Configuration.preferences.javaScriptCanOpenWindowsAutomatically = YES;
    // web內(nèi)容處理池
    Configuration.processPool = [[WKProcessPool alloc] init];
    //自定義配置,一般用于 js調(diào)用oc方法(OC攔截URL中的數(shù)據(jù)做自定義操作)
    WKUserContentController * UserContentController = [[WKUserContentController alloc]init];
    // 添加消息處理，注意：self指代的對象需要遵守WKScriptMessageHandler協(xié)議，結束時需要移除
    [UserContentController addScriptMessageHandler:self name:@"download"];//DownloadPolicy
    // 是否支持記憶讀取
    Configuration.suppressesIncrementalRendering = YES;
    // 允許用戶更改網(wǎng)頁的設置
    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];
    // 設置代理
    _wkWebView.navigationDelegate = self;
    _wkWebView.UIDelegate = self;
    // 垂直滾動
    [_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);
    //開啟手勢觸摸
    _wkWebView.allowsBackForwardNavigationGestures = YES;
    // 設置 可以前進 和 后退
    //適應你設定的尺寸
    [_wkWebView sizeToFit];
    [self.view addSubview:_wkWebView];
  }
  return _wkWebView;
}

iOS 9 以后和 iOS 8 之前加載方法不一樣，做區(qū)分

- (void)viewDidLoad {
  [super viewDidLoad];
  NSFileManager *fileManager = [NSFileManager defaultManager];
  NSArray *array1 = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
  NSString *matPath2 = [[array1 objectAtIndex:0] stringByAppendingPathComponent:@"QueHTML"];;
  if (![fileManager fileExistsAtPath:matPath2]) {
    NSString *matString = [[NSBundle mainBundle] pathForResource:@"QueHTML" ofType:@"bundle"];
    dispatch_async(dispatch_get_global_queue(0, 0), ^{
      [fileManager removeItemAtPath:matPath2 error:nil];
      [fileManager copyItemAtPath:matString toPath:matPath2 error:nil];
      dispatch_async(dispatch_get_main_queue(), ^{
        NSLog(@"創(chuàng)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]];
  }
}

實現(xiàn)代理方法

// 接收到服務器跳轉請求之后調(diào)用
- (void)webView:(WKWebView *)webView didReceiveServerRedirectForProvisionalNavigation:(WKNavigation *)navigation{
  NSLog(@"接收到服務器跳轉請求----%@",navigation);
}
// 在收到響應后，決定是否跳轉
- (void)webView:(WKWebView *)webView decidePolicyForNavigationResponse:(WKNavigationResponse *)navigationResponse decisionHandler:(void (^)(WKNavigationResponsePolicy))decisionHandler{
  NSLog(@"在收到響應后，決定是否跳轉---%@",navigationResponse.response.URL.absoluteString);
  //允許跳轉
  decisionHandler(WKNavigationResponsePolicyAllow);
  //不允許跳轉
  //decisionHandler(WKNavigationResponsePolicyCancel);
}
// 在發(fā)送請求之前，決定是否跳轉
- (void)webView:(WKWebView *)webView decidePolicyForNavigationAction:(WKNavigationAction *)navigationAction decisionHandler:(void (^)(WKNavigationActionPolicy))decisionHandler{
  NSLog(@"在發(fā)送請求之前，決定是否跳轉---%@",navigationAction.request.URL.absoluteString);
  //允許跳轉
  decisionHandler(WKNavigationActionPolicyAllow);
  //不允許跳轉
  //decisionHandler(WKNavigationActionPolicyCancel);
}
#pragma mark - WKNavigationDelegate
// 頁面開始加載時調(diào)用
- (void)webView:(WKWebView *)webView didStartProvisionalNavigation:(WKNavigation *)navigation{
  NSLog(@"頁面開始加載");
}
// 當內(nèi)容開始返回時調(diào)用
- (void)webView:(WKWebView *)webView didCommitNavigation:(WKNavigation *)navigation{
  NSLog(@"內(nèi)容開始返回");
}
// 頁面加載完成之后調(diào)用
- (void)webView:(WKWebView *)webView didFinishNavigation:(WKNavigation *)navigation{
  NSLog(@"頁面加載完成");
}
// 頁面加載失敗時調(diào)用
- (void)webView:(WKWebView *)webView didFailProvisionalNavigation:(WKNavigation *)navigation{
  NSLog(@"頁面加載失敗");
}

如果是https訪問需加上一下代碼

- (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);
  }
}
