I'm using an UIWebView for viewing .pdf, .txt, .xls, .ppt files. I used webView loadRequest method for viewing these files and its working fine. I need to view files such as .odp, .odt, .ods etc, but its showing only blank page in UIWebView. Is there any effective method for viewing these files using UIWebView or any direct method for doing the same?
Have you tried using the UIWebView method load, specifying the MIME type? For example for an .odt file:
webView.load(loadedData as Data, mimeType: "application/vnd.oasis.opendocument.text", textEncodingName: "utf-8", baseURL: NSURL() as URL)
If that does not work, then I'm afraid you'll have to write your own open office document loader...
WebODF libs integration with UIWebView: Integrated WebODF libs with UIWebView and it's working fine. Please find the below steps
1) Load index.html file from WebODF libs on UIWebView
2) Inject .odt file On webViewDidFinishLoad using below code snippet
let jsFunction = "createEditor(\"../default.odt\", \"Test\", 375, 667)"
webView.stringByEvaluatingJavaScript(from: jsFunction)
3) Successfully load the odt file.

I am trying to load html page in WKWebView which is linked to external javascript and css files. My web view shows me the html page but it does not seem like that its respecting css file values. Can anyone please suggest me as to what am I doing wrong here. Following my code to add html page in WKWebView:
override func viewDidLoad() {
super.viewDidLoad()
let path = NSBundle.mainBundle().pathForResource("index", ofType: "html");
let htmlString = String.stringWithContentsOfFile(path, encoding: NSUTF8StringEncoding, error: nil);
self.webView.loadHTMLString(htmlString, baseURL: NSURL.fileURLWithPath(NSBundle.mainBundle().bundlePath));
}
Also, here is the project structure where .css, .js and .html files re added.
Any help would be appreciated.
The problem is that the WKWebView renders page content inside a sandbox process that cannot access files in your application bundle. This effectively means that file:// URLs do not work.
I ended up including a small web server in my application to make it easier to serve content to the WKWebView.
Currently I have a basic WebView set up with JavaFX and a html file that I need to load in my local home folder. However, when I set a URL object to the home folder and try to load that URL using the WebEngine's load function, the page does not load. The page content.html is perfectly fine. Here is my code:
String contentURL = new URL("file://" + System.getProperty("user.home") + "/content.html").toExternalForm();
webEngine.load(contentURL);
System.out.println(contentURL);
Put an extra slash to file protocol; "file:///". For more info follow this wiki.
I'm doing the task of changing the rtf files to html files. However,how to read .html files to NSTextView or other Object.I test the following API works well in reading HTML file.
NSTextView *showHtml;
[showHtml readRTFDFromFile:[[NSBundle mainBundle] pathForResource:#"test" ofType:#"html"]];
The object showHtml can shows Html files as the browse does.
But The API readRTFDFromFile descript like that only read rtf or rtfd files.
Are there any API or method to shows Html file in xib.
I also test the API:
[[NSAttributedString alloc] initWithHTML:(NSData *) data documentAttributes:(NSDictionary **) docAttributes],
setAttributedStringValue:(NSAttributedString *) aAttributeString
But It can't shows the attribution except the string .
Thanks for your reply.
Trying to fix an old .asp site to work on an ipad. One of the features is the users ability to download their search results into an excel worksheet. The code uses:
Response.ContentType = "application/vnd.ms-excel"
Response.AddHeader "Content-Disposition", "attachment;filename=results.xls"
Response.CharSet = "iso-8859-1"
When viewing the site on the ipad, when the link is click for the page with the code above it does nothing, just spins. Is it the fact that I am trying to export the data as excel, I have read in some posts how it is the encoding! Should I convert the code to export the results page as a csv file and then allow the user to open it in anything they want/have available? What's the best way to do it to hit the most devices...
Thanks
In the past i'd a same scenario so what i did:
FILE: DOWNLOAD.ASP
<%
' get the file to download
myFile = request.querystring("File")
myFullPath = "c:\name_folder\" & myFile ' example of full path and filename
' set headers
Response.ContentType = "application/octet-stream"
Response.AddHeader "Content-Disposition", "attachment; filename=" & myFile
' send the file using the stream as
Set adoStream = CreateObject("ADODB.Stream")
adoStream.Open()
adoStream.Type = 1
adoStream.LoadFromFile(myFullPath)
Response.BinaryWrite adoStream.Read()
adoStream.Close
Set adoStream = Nothing
%>
FILE: HTML
Download Excel file
This example is full working with Ipad using the native browser Safari.
The file Result.xls is downloaded and loaded in the Viewer whitout the capability to be edit.
My iPad users use the App QuickOffice to let the file be saved in a virtual folder, rename the file, delete, ... but they cant edit the file, that App is just for manage the files and isnt required for download the file.
If your user need also edit the XLS file on the iPad i suggest to use (for example) the Google App Document, it let the user to edit and manage the file directly in the browser.
Hope it help
How do I (in my controller) send a pdf that opens in the browser. I have tried this but it only downloads the file (both ie and firefox) without asking.
public ActionResult GetIt()
{
var filename = #"C:\path\to\pdf\test.pdf";
// Edit start
ControllerContext.HttpContext.Response.AddHeader("Content-Disposition", String.Format("inline;filename=\"{0}\"", "test.pdf"));
// Edit stop
return File(filename, "application/pdf", Server.HtmlEncode(filename));
}
After adding the edit above it works as it should, thanks.
You need to set the Content disposition HTTP header to inline to indicate to the browser that it should try to use a PDF plugin if it is available.
Something like: Content-Disposition: inline; filename=test.pdf
Note that you cannot force the use of the plugin, it is a decision made by the browser.
This (in addition to the other headers) does the trick for me in a plain .net web app:
Response.AddHeader("Content-Disposition", String.Format("inline;filename=""{0}""", FileName))
I'm not familiar with MVC, but hopefully this helps.
I think this relies on how the client handles PDF files. If it has setup to let Adobe Reader open the files in the browser plugin it will do that, but maybe you have set it up to download the file rather than opening it.
In any case, there is no way of controlling how PDF files will be opened on the user's machine.
