ios webview加载本地网页并解决乱码问题

例如 NSString *htmlpath = [[[NSBundle mainBundle]resourcePath]stringByAppendingPathComponent@"xx.html"];
NSString *htmlstring = [NSString stringWithContentsOfFile:htmlpath];
[webview loadHTMLString:htmlstring baseUrl:nil];

如果需要用本地图片的话 BASEURL 路径设置为自己的RESOURCE

如果有乱码问题；

//加载本地的html文件
NSString *resourcePath = [[NSBundle mainBundle] resourcePath];    
NSString *filePath = [resourcePath stringByAppendingPathComponent:@"common_problem.html"];    

//以utf8的编码格式加载html内容
NSString *htmlString = [[NSString alloc] initWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:nil]; 
//self.wbProblems.scalesPageToFit = YES;
//将文字内容显示到webview控件上
[self.wbProblems loadHTMLString: htmlString baseURL: [NSURL fileURLWithPath:[[NSBundle mainBundle] bundlePath]]];
