- (void)loadData:(NSData *)data MIMEType:(NSString *)MIMEType textEncodingName:(NSString *)textEncodingName baseURL:(NSURL *)baseURL;

 UIWebView *webView = [[UIWebView alloc]initWithFrame:[UIScreen mainScreen].bounds];

    webView.delegate = self;

    webView.scalesPageToFit = YES;

    [self.view addSubview:webView];

    NSString *str = @"http://xxxxx.doc";

    //转化网址中的中文字符

    NSString *string = [str stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLFragmentAllowedCharacterSet]];

    //将字符串转化为URL类型的格式

    NSURL *url2 = [NSURL URLWithString:string];

    //加载数据

    NSData *data = [NSData dataWithContentsOfURL:url2];

    dispatch_queue_t globalQueue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0);

    dispatch_async(globalQueue, ^{

        dispatch_async(dispatch_get_main_queue(), ^{

            [webView loadData:data MIMEType:@"application/doc" textEncodingName:@"UTF-8" baseURL:url2];

        });

    });

    /**
