I want to open RSS Feed in my UIWebView, but it isn't working and opening Safari.
My code:
NSString *link = [[NSString alloc] initWithFormat:#"feed://smartfiction.disqus.com/%#/latest.rss", slug];
NSURL *url = [NSURL URLWithString:link];
NSURLRequest *requestWeb = [NSURLRequest requestWithURL:url];
[webViewComment loadRequest:requestWeb];
I found right way. I have created rss parser and showed feed in UITableView. It's more beautiful and easy.
feed:// is a URL Scheme which is handled by Safari and so will only be opened by Safari... you could try :
NSString *link = [[NSString alloc] initWithFormat:#"feed://smartfiction.disqus.com/%#/latest.rss", slug];
NSURL *url = [NSURL URLWithString:link];
NSData *rssData = [NSData dataWithContentsOfURL:url];
[webViewComment loadData:rssData MIMEtype:#"application/rss+xml" textEncodingName:#"utf-8" baseURL:nil];

I have a UIWebView which is adapted to a mobile style of a forum I have. In Safari, it looks and works great.
However, inside my WebView there is a disastrous problem.
When quoting or editing a post, HTML is displayed inside of BBcode. Furthermore, posting code results in ignored line breaks.
The webview is loaded like this:
//display the webview
NSString *fullURL = #"http://www.mysite.com";
NSURL *url = [NSURL URLWithString:fullURL];
NSMutableURLRequest *requestObj = [NSMutableURLRequest requestWithURL:url];
[_webTest loadRequest:requestObj];
Change your this line:
NSMutableURLRequest *requestObj = [NSMutableURLRequest requestWithURL:url];
With this line & check:
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
Do you want to load a html-string in your webView?
If it is the thing than following may help you:
NSString *bundlePath = [[NSBundle mainBundle] bundlePath];
NSURL *baseURL = [NSURL fileURLWithPath:bundlePath];
NSString *htmlString = [bundlePath pathForResource:#"index" ofType:#"html"] ;
[webView loadHTMLString:htmlString baseURL:baseURL];
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 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"
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]]];
}
I have made a project and when people put a keyword into UITextfield and click the button then my app will retrieve the data from website database.
It is not working here is the code:
- (IBAction) btnClickMe_Clicked:(id)sender {
NSString *kw = s.text; // <-----THIS IS THE UITextField
NSURL *url = [NSURL URLWithString:#"http://www.example.com/index.php?keyword=",kw];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[iMessageLabel loadRequest:request];
}
Any one could help me?
You aren't putting the keyword into the string. You need something like this:
NSString *kw = s.text;
NSString *encodedkw = [ky stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSString *urlString = [NSString stringWithFormat: #"http://www.example.com/index.php?keyword=%#", encodedkw];
NSURL *url = [NSURL URLWithString:urlString];
Then look at how to use NSURLConnection to figure out how to put the data into the label.
