I use this line of code to load a local html file into a web view:
NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:#"index" ofType:#"html" inDirectory:#"html"]];
However I want to add some http parameters to the url with no luck so far.
I've tried this:
url = [url URLByAppendingPathComponent:#"?param1=1"];
But after this a html doesn't load in webview.
Is there a way to load local html file in webview with params ?
Do this:
NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:#"index" ofType:#"html" inDirectory:#"html"]];
NSString *URLString = [url absoluteString];
NSString *queryString = #"?param1=1";
NSString *URLwithQueryString = [URLString stringByAppendingString: queryString];
NSURL *finalURL = [NSURL URLWithString:URLwithQueryString];
NSURLRequest *request = [NSURLRequest requestWithURL:finalURL cachePolicy:NSURLRequestReloadIgnoringCacheData timeoutInterval:(NSTimeInterval)10.0 ];
[web loadRequest:request];
The most upvoted answer by Prince doesn't always work.
In iOS 7 Apple introduced NSURLComponents class, we can leverage that to securely add a query into NSURL.
NSURL *contentURL = ...;
NSURLComponents *components = [[NSURLComponents alloc] initWithURL:contentURL resolvingAgainstBaseURL:NO];
NSMutableArray *queryItems = [components.queryItems mutableCopy];
if (!queryItems) queryItems = [[NSMutableArray alloc] init];
[queryItems addObject:[NSURLQueryItem queryItemWithName:#"access_token" value:#"token_here"]];
components.queryItems = queryItems;
NSURL *newURL = components.URL;
I use like this way:
NSURL *url=[NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:#"index" ofType:#"xml"]];
If your file included into the Resource folder of project navigator. otherwise you have to set your full path in NSString and use that in your NSURL path.

I want to use an HTML file in my code currently I am using following line of code:
NSString *htmlFile = [[NSBundle mainBundle] pathForResource:#"index" ofType:#"htm" inDirectory:nil];
NSString* htmlString = [NSString stringWithContentsOfFile:htmlFile encoding:NSUTF8StringEncoding error:nil];
[WebView loadHTMLString:htmlString baseURL:nil];
But the problem which I am facing is: the HTML Page contains some images, and all that images are in a folder in my project but I am not able to see that images in the HTML page at run time.
You can set the baseURL to your resource folder, where your images are located:
NSString *htmlFile = [[NSBundle mainBundle] pathForResource:#"index" ofType:#"htm" inDirectory:nil];
NSString *htmlString = [NSString stringWithContentsOfFile:htmlFile encoding:NSUTF8StringEncoding error:nil];
NSString *resourcePath = [[NSBundle mainBundle]resourcePath];
NSURL *baseUrl = [[NSURL alloc]initFileURLWithPath:resourcePath];
[self.myWebView loadHTMLString:htlmString baseURL:baseUrl];
Here the possible ways to use HTML into the project,
Following code for the load HTML file into xcode project
Example 1, loading the content from a URLNSURL
NSURL *url = [NSURL URLWithString:#"http://google.com"];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[webView loadRequest:request];
Example 2, loading the content from a string
NSString *HTMLData = #"<h1>Hello this is a test</h1>";
[webView loadHTMLString:HTMLData baseURL:nil];
Example 3, loading the content from a local file
NSString *htmlFile = [[NSBundle mainBundle] pathForResource:#"sample" ofType:#"html"];
NSData *htmlData = [NSData dataWithContentsOfFile:htmlFile];
[webView loadData:htmlData MIMEType:#"text/html" textEncodingName:#"UTF-8" baseURL:[NSURL URLWithString:#""]];
Hope this code helping to develop a application
I am trying to eneble a button to download a pdf file from a server.
(Onto the divice)
I'm not being successful with this code (to post this question, i've changed the address)
Would you give me some advice to make it work..?
Thanks in advance.
NSData *pdfData = [[NSData alloc] initWithContentsOfURL:[NSURL URLWithString:#"http://www.mydomain.com/mypdffile.pdf"]];
//Store the Data locally as PDF File
NSString *resourceDocPath = [[NSString alloc] initWithString:[[[[NSBundle mainBundle] resourcePath] stringByDeletingLastPathComponent] stringByAppendingPathComponent:#"<Application_Home>/Documents/"]];
NSString *filePath = [resourceDocPath stringByAppendingPathComponent:#"myPDF.pdf"];
[pdfData writeToFile:filePath atomically:YES];
//Now create Request for the file that was saved in your documents folder
NSURL *url = [NSURL fileURLWithPath:filePath];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
[webView setUserInteractionEnabled:YES];
[webView setDelegate:self];
[webView loadRequest:requestObj];
You are not building a correct NSURL object to reach a server. fileURLWithPath: is a method to build URL that points to files in the file system.
Use URLWithString: writing the complete url, that is for example "http://myserver.com/myfile.pdf"
NSURL *pdfURL = [[NSBundle mainBundle] URLForResource:#"sampleLayout.pdf" withExtension:nil];
This above line warns NSBundle may not respond to -URLForResource:withExtension:
and the app crashes while loading the PDF file from this URL path.
Why dont you try like this..?
NSString *urlPath = [[NSBundle mainBundle] pathForResource:#"test" ofType:#"pdf"];
NSURL *url = [NSURL fileURLWithPath:urlPath];
NSURLRequest *urlRequest = [NSURLRequest requestWithURL:url];
[webViewOutlet loadRequest:urlRequest];
NSURL *pdfPath = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource:#"test" ofType:#"pdf"]];
i got working from this above line, i think this is alternative for ipad 3.2 from iphone 4.0 os
I have HTML files that I want to load locally. I have included the files in the resources folder in XCode. I am not sure what the syntax is to load them.
This is the code I use to connect to say google.
NSString *urlAddress=#"http\\someurl";
NSURL *url = [NSURL URLWithString:urlAddress];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
[webHelpView loadRequest:requestObj];
Could someone provide an example where a HTML file is loaded locally.
Thanks in advance.
This is the only code that worked for me.
NSString *path = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:#"SettingsHelp.html"];
NSURL *url = [NSURL fileURLWithPath:path isDirectory:NO];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
Thanks all for the help.
Can't you just do
NSURL *url = [NSURL URLWithString:#"file:///path/to/file"];
?
Sure, here is some code from an app that loads a locallly stored html page into a web view:
- (void) viewDidLoad
{
// Load the content into the view
NSString* path = [NSString stringWithFormat: #"%#/index.html",
[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex: 0]];
[webView_ loadRequest: [NSURLRequest requestWithURL: [NSURL fileURLWithPath: path]]];
}
Here is my code :
NSString *path1 = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:#"NewSouthWales.html"];
NSURL *pageURL = [NSURL fileURLWithPath:path1];
//URL Requst Object
NSURLRequest *requestObj = [NSURLRequest requestWithURL:pageURL];
//Load the request in the UIWebView.
[self.webView loadRequest:requestObj];
I am getting output in my webview as :
like
........
instead of giving me proper look of that file it shows page source code.
Please help ...
Thanks in advance
First prefer pathForRessource ofType
pathNSString *path1 = [[NSBundle mainBundle] pathForResource:#"NewSouthWales" ofType:#"html"];
And then if the file is local why send a request ?
Just use :
NSString *html = [NSString stringWithContentsOfFile:path1 encoding:NSUTF8StringEncoding error:nil];
[self.webView loadHTMLString:html baseURL:[NSURL fileURLWithPath:[[NSBundle mainBundle]bundlePath]]];
NSString *path1 = [[NSBundle mainBundle] pathForResource:#"NewSouthWales" ofType:#"html"];
NSURL *baseurl = [NSURL fileURLWithPath:path1];
NSData *pathData = [NSData dataWithContentsOfFile:path1];
//Check first if the file path's data is captured. if true, load the html on the web view
if (pathData) {
[webView loadData:pathData MIMEType:#"text/html" textEncodingName:#"UTF-8" baseURL:baseurl];
}
