I want to write html code locally and show it in UIWebview ,so for this ,I have taken a simple html code ,as below and created a .html extension file..
<html>
<body>
<h1>My First Heading</h1>
<p>My first paragraph.</p>
</body>
</html>
I added this file into my xcode project ,now I want to load this file inside webview ,so I have written this code
[m_websiteView loadRequest:[NSURLRequest requestWithURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:#"test" ofType:#"html"]isDirectory:NO]]];
but the output I get when I run this code in UIWebView is same htmlcode, I cant figure out what the problem is..but when I tried using this code
NSString *path = [[NSBundle mainBundle] bundlePath];
NSURL *baseURL = [NSURL fileURLWithPath:path];
NSString *testString = #"<h1><i>This is an image using reference in HTML</i></h1>"
"<img src='active.png'></img>";
[m_websiteView loadHTMLString:testString baseURL:baseURL];
this works perfect.also I want to localize the strings in this html code,so in the above code,how can I localize this string "This is an image using reference in HTML"..
Regards
Ranjit
Add localization, use this
NSString *testString = [NSString stringWithFormat:
#"<h1><i>%#</i></h1><img src='active.png'></img>",
NSLocalizedString(#"This is an image using reference in HTML", #"htmlText")];
and specify the localize strings in the file Localizable.strings in the correct language directory.
You can also localized entire (HTML) files with the locale directory scheme.
HTML syntax is
<html>
<head>
</head>
<body>
</body>
</html>
after that you can preview your html file using something like that in your view controller
CGRect webFrame = CGRectMake(0.0, 0.0, 320.0, 460.0);
UIWebView *webView = [[UIWebView alloc] initWithFrame:webFrame];
[webView setBackgroundColor:[UIColor whiteColor]];
NSString *urlAddress = #"http://www.istoselidas.gr";
NSURL *url = [NSURL URLWithString:urlAddress];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
[webView loadRequest:requestObj];
[self addSubview:webView];
[webView release];
just replace url with your html file

I'm trying to load a javascript file but it doesn't work.
My code :
NSString *html = [NSString stringWithFormat:#"<html><head></head><body><script type=\"text/javascript\" src=\"http://mywebsite.com/file.js\"></script></body></html>"];
[_webView loadHTMLString:html baseURL:nil];
This code is supposed to display a video, but nothing happens.
This code displays correctly the video in Desktop browser, my JS is correct.
use url in baseURL
NSURL *base=[NSURL URLWithString:#"website.com"];
Do not use string description. Instead use:
[_webView loadHTMLString:html baseURL:nil];
Write following code in - webViewDidFinishLoad:
NSString * strJavaScript = [NSString stringWithContentsOfURL:[NSURL URLWithString:#"http://mywebsite.com/file.js"] encoding:NSUTF8StringEncoding error:nil];
[_webView stringByEvaluatingJavaScriptFromString:strJavaScript];
In iOS, I need to load a website in uiwebview and I want to add a local image at the beginning of the webpage.
I added < img src="logo.png"/> after < body > tag but it only showed a null pic(a small white box).
How can I load my local image as the src of the img inside the html? Thanks
Using relative paths or file: paths to refer to images does not work with UIWebView. Instead you have to load the HTML into the view with the correct baseURL:
NSString *path = [[NSBundle mainBundle] bundlePath];
NSURL *baseURL = [NSURL fileURLWithPath:path];
[webView loadHTMLString:htmlString baseURL:baseURL];
You can then refer to your images like this:
(from uiwebview revisited)
You have to define the extact path of the image source see code below
NSString *imagePath=[[NSBundle mainBundle] pathForResource:#"image" ofType:#"png"];
imagePath=[NSString stringWithFormat:#"file://%#",imagePath];
NSString *html=[NSString stringWithFormat:#"<html><body><img src=\"%#\"/></body></html>",imagePath];
[webView loadHTMLString:html baseURL:nil];
Cheers.
I am using Webview to load a image file stored in my app Library Directory, first i tried use resourcePath, and bundle path
NSString * html = [[NSString alloc] initWithFormat:#"<img src=\"file://%#\"/>", filename];
[self.webView loadHTMLString:newhtml baseURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] resourcePath]]];
the problem is no matter what i set in the baseUrl, i can not load the image correctly , i also tried filePath:
[self.webView loadHTMLString:newhtml baseURL:[NSURL fileURLWithPath:[[NSBundle mainBundle] filePath]]];
but if i set the absolute path of the image file in the html , all the things is ok, i wonder why?
Have a look at this post: Using HTML and Local Images Within UIWebView
The top answer clearly said that using file: paths to refer to images does not work with UIWebView.
All you need to do is to pass the basepath. Example:
NSString *path = [[NSBundle mainBundle] bundlePath];
NSURL *baseURL = [NSURL fileURLWithPath:path];
[webView loadHTMLString:htmlString baseURL:baseURL];
Then just need to reference it like this: <img src="myimage.png">
I am trying to load a local html content into uiwebview. I already have the html content ready with me, and i am adding a reference a online css file to the content by the mechanism as shown in the code below. However, the problem i am facing is when i load the webview, there is no styling. Also, I verified in the Charles Proxy, there is no outgoing call for fetching iphone.css file to my base server. Ideally, while loading a html page, uiwebview should get all the referred resources, but for some reason unknown to me, it is not fetching the css file.
Please review and let me know if there is some issue with my code that i am not able to identify here?
NSString* htmlString = #"<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.0 Transitional//EN\" \"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd\"> <html xmlns=\"http://www.w3.org/1999/xhtml\" xml:lang=\"he\" lang=\"he\"><head><link type=\"text/css\" href=\"http://<base_server>/resources/iphone.css\" /><meta http-equiv=\"Content-Type\" content=\"text/html; charset=UTF-8\" /></head><body>%#</body></html>";
UIWebView *webview = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0, frame.size.width, frame.size.height)];
NSLog(#"%#",[NSString stringWithFormat:htmlString,entry.body]);
[webview loadHTMLString:[NSString stringWithFormat:htmlString,entry.body] baseURL:[NSURL URLWithString:#"http://<base_server>/"]];
[self addSubview:webview];
It's hard to tell if there are any typos in the HTML with all of the double quote escaping going on in that string. Why don't you pull the HTML out of the string and into a file, read that file in and place your content in the body. There may be a mistake with the markup in that string. This would allow you to read it easier in a seperate file.
Something like:
NSError *error;
NSStringEncoding encoding;
NSString *htmlFilePath = [[NSBundle mainBundle] pathForResource: #"Sample"
ofType: #"html"];
NSString *htmlString = [NSString stringWithContentsOfFile:htmlFilePath
usedEncoding:&encoding
error:&error];
NSString *html = [NSString stringWithFormat:htmlString, entry.body];
NSString *path = [[NSBundle mainBundle] bundlePath];
NSURL *baseURL = [NSURL fileURLWithPath:path];
[webview loadHTMLString:html baseURL:baseURL];
I've a problem that i couldn't solve, i wanna run the Apple - HTML5 Showcase - Gallary
in UIWebView inside my ipad app.
I've tried a local html file:
NSString *strr = [[NSBundle mainBundle] pathForResource:#"photo-gallery" ofType:#"html"];
NSString *str = [[NSString alloc] initWithContentsOfFile:strr encoding:NSASCIIStringEncoding error:nil];
NSLog(#"%#",str);
[webView loadHTMLString:str baseURL:nil];
and also a server html file, but it didn't work, can anyone help me, i wanna show an html5/css3 in UIWebView.
thx in advance.
hi this is what you can do
UIWebView *aWebView = [[UIWebView alloc] initWithFrame:webFrame];
//getthe path of the local html file
NSURL *baseURL = [NSURL fileURLWithPath:fileNamePath];
NSURLRequest *aRequest = [NSURLRequest requestWithURL:baseURL];
//load the html file into the web view.
[aWebView loadRequest:aRequest];
//add the web view to the content view
[view addSubview:aWebView];
For server html you simply skip the second line, and put the address.
Hope it helps
You can take a look at phonegap. Its a complete framework for building html5 apps inside a UIWebview with native capabilities.
