大家都知道，使用UIWebView加载本地或远程服务器上的网页，sdk提供了三个加载接口：- (void)loadRequest:(NSURLRequest *)request; - (void)loadHTMLString:(NSString *)string baseURL:(NSURL *)baseURL;- (void)loadData:(NSData *)data MIMEType:(NSString *)MIMEType textEncodingName:(NSString *)textEncodingName baseURL:(NSURL *)baseURL;- (void)loadRequest:(NSURLRequest *)request; 这个接口一般用于加载url所指定的某个远程服务器网页，其实它也能用来加载本地网页资源。//加载远程网页[self.myWebView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:@"http://www.baidu.com"]]];//加载本地网页NSString *filePath = [[NSBundle mainBundle] pathForResource:@"kline71" ofType:@"html" inDirectory:@"XiangJie"];[self.myWebView loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:filePath]]];注意：网页可能会使用其他的如图片资源，css样式文件，loadRequest会在网页的当前目录下（如本例中的XiangJie目录下查找）- (void)loadHTMLString:(NSString *)string baseURL:(NSURL *)baseURL;这个接口用于直接加载html代码。如果html直接写在了代码中，推荐使用这种方法。当然你也可以先从本地读取html代码，然后加载。请注意baseURL地址目录要正确，否则html中引用的资源是找不到的。NSString *filePath = [[NSBundle mainBundle] pathForResource:@"kline71" ofType:@"html" inDirectory:@"XiangJie"];NSString *htmlString = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:nil];NSString *baseURL = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"XiangJie/img"];[_myWebView loadHTMLString:htmlString baseURL:[NSURL URLWithString:baseURL]];- (void)loadData:(NSData *)data MIMEType:(NSString *)MIMEType textEncodingName:(NSString *)textEncodingName baseURL:(NSURL *)baseURL;这个接口用于加载html文件。MIMEType值一般为"text/html"。同样，请注意baseURL地址目录要正确，否则html中引用的资源是找不到的。NSString *filePath = [[NSBundle mainBundle] pathForResource:@"kline71" ofType:@"html" inDirectory:@"XiangJie"];NSData *data = [NSData dataWithContentsOfFile:filePath];NSString *baseURL = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"XiangJie/img"];[self.myWebView loadData:data MIMEType:@"text/html" textEncodingName:@"utf-8" baseURL:[NSURL URLWithString:baseURL]];
