用UIWebView就可以了
-(void)loadDocument:(NSString*)documentName inView:(UIWebView*)webView
{
    NSString *path = [[NSBundle mainBundle] pathForResource:documentName ofType:nil];
    NSURL *url = [NSURL fileURLWithPath:path];
    NSURLRequest *request = [NSURLRequest requestWithURL:url];
    [webView loadRequest:request];
}

// Calling -loadDocument:inView:
[self loadDocument:@"test.doc" inView:self.myWebview];
