OPTION 1

选项1

Use this

用这个

- (void)loadHTMLString:(NSString *)string baseURL:(NSURL *)baseURL

Read the contents of the file in your project into an NSString. Then use the above method to load the html content

将项目中文件的内容读入NSString. 然后使用上面的方法来加载HTML内容

Use

用

+ (id)stringWithContentsOfFile:(NSString *)path encoding:(NSStringEncoding)enc error:(NSError **)error

to obtain the string from the file and then use

从文件中获取字符串，然后使用

[webView loadHTMLString:urHTMLString baseURL:baseURL];

OPTION 2

选项 2

NSURLRequest *urlReq = [NSURLRequest requestWithURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"fileName" ofType:@"html"]]];
[webView loadRequest:urlReq];

UPDATE

更新

- (void)loadAboutHTML {
UIWebView *aboutHTML = [[UIWebView alloc] init];
NSURLRequest *urlRequest = [NSURLRequest requestWithURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:@"yourFileName" ofType:@"html"]]];
[aboutHTML loadRequest:urlRequest;
[self addSubview:aboutHTML];
}

may be the answer of the solution

CGRect applicationFrame = [[UIScreen mainScreen] applicationFrame];
    applicationFrame.origin.y = 0;
    webView = [[UIWebView alloc] initWithFrame:applicationFrame];
    webView.autoresizingMask = (UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight);

    NSString *basePath = [[NSBundle mainBundle] bundlePath];
    NSURL *baseURL = [NSURL fileURLWithPath:basePath];
    NSString *filePath = [[NSBundle mainBundle] pathForResource:@"index" ofType:@"html"];
    NSString *htmlString = [NSString stringWithContentsOfFile:filePath];
    if (htmlString) {
        [webView loadHTMLString:htmlString baseURL:baseURL];
    }

    [self.view addSubview:webView];

}
//delegates
- (void)webViewDidFinishLoad:(UIWebView *)webView

}

- (void)webView:(UIWebView *)webView didFailLoadWithError:(NSError *)error

}

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType

    if(UIWebViewNavigationTypeOther == navigationType)
