本文介绍如何使用UIWebView加载工程内的本地网页及图片资源，并通过JavaScript动态设置图片路径。

UIWebView加载工程本地网页与本地图片

- (void)viewDidLoad
{
    [super viewDidLoad];

    NSString *filePath = [[NSBundle mainBundle]pathForResource:@"1" ofType:@"html"];
    NSString *htmlString = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:nil];

    myWebView = [[UIWebView alloc] initWithFrame:self.view.bounds];
    myWebView.delegate = self;
    [self.view addSubview:myWebView];

    [myWebView loadHTMLString:htmlString baseURL:[NSURL URLWithString:filePath]];

}

-(void)webViewDidFinishLoad:(UIWebView *)webView
{
    NSString *imagePath = [[NSBundle mainBundle] resourcePath];
    imagePath = [imagePath stringByReplacingOccurrencesOfString:@"/" withString:@"//"];
    imagePath = [imagePath stringByReplacingOccurrencesOfString:@" " withString:@"%20"];
    NSString * js = [NSString stringWithFormat:@"document.images[0].src='file:/%@//%@'",imagePath,@"icon-04.png"];

    [myWebView stringByEvaluatingJavaScriptFromString:js];
    NSString *path = [myWebView stringByEvaluatingJavaScriptFromString:@"document.images[0].src"];
    NSLog(@"path:%@", path);
}

图片+文字是最好的说明，希望可以帮到忙。
