載入檔案檔案，如 .pdf .txt .doc 等

我們也可以將文件檔案載入到 iOS WebView 中，而不是網頁，如 .pdf，.txt，.doc 等 .loadData 方法用於將 NSData 載入到 webview 中。

迅速

//Assuming there is a text file in the project named "home.txt".
let localFilePath = NSBundle.mainBundle().pathForResource("home", ofType:"txt");
let data = NSFileManager.defaultManager().contentsAtPath(localFilePath!);
webview.loadData(data!, MIMEType: "application/txt", textEncodingName:"UTF-8" , baseURL: NSURL())

Objective-C

//Assuming there is a text file in the project named "home.txt".
NSString *localFilePath = [[NSBundle mainBundle] pathForResource:@"home" ofType:@"txt"];
NSData *data = [[NSFileManager defaultManager] contentsAtPath:localFilePath];
[webview loadData:data MIMEType:@"application/txt" textEncodingName:@"UTF-8" baseURL:[NSURL new]];
