iOS開發：加載本地文件到UIWebView的方法

關鍵是生成“文件URL”

1. NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUSErDomainMask, YES);
2. NSString *documentsDirectory = [paths objectAtIndex:0];
3. NSString *path = [documentsDirectory stringByAppendingPathComponent:docName];
4. NSURL *url = [NSURL fileURLWithPath:path];
5. NSURLRequest *request = [NSURLRequest requestWithURL:url];
7. self.myWebView.scalesPageToFit = YES;
9. [self.myWebView loadRequest:request];

如果是資源文件，則用獲取路徑

1. NSString *mainBundleDirectory = [[NSBundle mainBundle] bundlePath];
2. NSString *path = [mainBundleDirectory stringByAppendingPathComponent:docName];
