I created an HTML file programmatically with images sources. The images are stored in the documents directory. The problem is that when I give the image source path as document directory path the images are not shown in Windows.
So, I choose the second option is to give only the image's name instead of whole path. Then it work well on Mac & Windows, but now images are not shown on the device's UIWebView.
Then I selected to open the HTML file in Safari insted of UIWebView, but the safari could not be opened because URL becomes NULL.
My code to open Safari is as follow:
NSLog(#"%#",documentsDirectory);
NSString *urlStr = [NSString stringWithFormat:#"%#/AccReport1.html",documentsDirectory];
NSLog(#"urlStr :: %#",urlStr);
NSURL *url1=[[NSURL alloc]init ];
url1 = [NSURL fileURLWithPath:urlStr];
NSLog(#"url :: %#",url1);
[[UIApplication sharedApplication]openURL:url1];
I want to mail the HTML file that contains images. And these HTML file and images are stored in document directory. I want to show this HTML file with images in windows browser, mac browser and iphone's safari.
How to do this?
One of the simple way to solve your problem is to keep Images and HTML file in same directory and refer those images in HTML files just by name and if you put them in a folder then give the complete path.
The images are not showing because the image path specified within the HTML code is not the documents directory path.
I suggest you might have to construct an html string and then subject the uiwebview to load that string
NSString *htmlString = [NSString stringWithFormat:#"<html><body><img src=\" %#/image.png \"></img></body></html>",documentsDirectoryPath];
[webView loadHTMLString:htmlString baseURL:nil];

I have a link that contains a downloadable pdf file. This link doesn't have its extension as .pdf, its just a normal link. Its a web-service where i pass "PDF" as a parameter that returns me a PDF file. Whenever I open such link on a desktop browser, it directly ask for downloading the pdf. Into my ipad app, i need to display such pdf in a web view. What can be the possible solution?
You should make a url request and load that in to a Webview like this,
NSURLRequest *request = [[NSURLRequest alloc] initWithURL:url];
[webView loadRequest:request];
The url is your link to the PDF file and webview is UIWebView object where you can view the PDF.
I am attempting to open an iWork 10 Numbers file placed on a Web site into a UIWebView. I tried with the following, and what happens is that the UIWebView loads blank. If I download the file to local the Documents folder and then load it in the UIWebView it then works. I'd like to read an iWork file without downloading them...
FYI, I have no issues with PDF, PPT, DOC, XLS...
Can anyone tell me how to load an iWork file from NSdata to UIWebView?
[webView loadData:receivedData
MIMEType:file.mediaMimetype
textEncodingName:nil
baseURL:[NSURL URLWithString:PATHTOFILE]
];
The tested values for mediaMimetype are:
application/vnd.apple.numbers
application/x-iwork-numbers-sffnumbers
You need to compress iWork file with .zip extension to display in webview.
refer this link for detail:

Given a pdf created with pages that includes working imbedded hyperlink, stored as a resource with my app and displayed in a UIWebView, what needs to be done to make the hyperlink work in in the UIWebView.
Scouring the posts here and elsewhere on this subject it appears that a link should just work if you want it to display in Safari. I can't get them to work.
In pages I created the document and created a hyperlink to http://www.excite.com/ for testing purposes. I then exported the document as a pdf. The link works fine when the pdf is displayed in Preview. I then added the pdf to my app resources folder and loaded it into the UIWebView. The link does not work.
The UIWebView was created with IB and I have the Links property checked.
I am loading the pdf with the following code...
NSString *pdfPath =[[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:[documents objectAtIndex:documentNumber]];
pdfUrl = [NSURL fileURLWithPath:pdfPath];
[webView loadRequest:[NSURLRequest requestWithURL:pdfUrl]];
What more do I need to do?
For now I just would like the link to open in Safari. Eventually I will need to have links that allow me to link to other pdfs in my resource folder and display them in the same UIWebView. To do this I understand I will need to implement a UIWebViewDelegate.
Thanks,
John
I am trying to load the contents of a rtf file in the UIWebView. I am successful in loading the contents, but it is unformatted. the fonts are too large and it doesn't have any format. it displays the color of the rtf content, but not the font or size.
So what should i do now. is there any other way to load the rtf and format it? I load the rtf in following way:
NSString *path = [[NSBundle mainBundle] pathForResource:#"Home" ofType:#"rtf"];
NSURL *url=[NSURL fileURLWithPath:path];
NSURLRequest *req=[NSURLRequest requestWithURL:url];
[menuWeb loadRequest:req];
So what should i do now?
Use HTML instead, it's the only way you're going to get the control you want.

This page is a WYSIWYG HTML generator. It generates extremely clean HTML (*), which I can then save and insert in my project. I can then modify this HTML file from within Xcode. All very nice!
(*) provided you use it right... flip between the normal view, HTML view and final view -- don't make it export into the second text box otherwise everything comes out in an impenetrable chunk.
i want to load just the html from the web and show the images from the local resource.
This helped me a lot, but is the path to the resource on every device the same? Or does it depend on an installation path or similar?
Load Content in the UIWebView on the Iphone
the path to resources is different on every device, that's why you use the function
[[NSBundle mainBundle] pathForResource:nameOfImage ofType:#"jpg"]
the html loading from the web you can do all kinds of ways. The easiest is just:
NSString *myHTML = [NSString stringWithContentsOfURL:[NSURL URLWithString:#"http://web.site.com/file.html"]];
