I want to load a specific part of a webpage on a UIWebView
[_webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:#"http://jlhs.schoolloop.com/mobile/login"]]];
[_webView loadHTMLString:#"<html><body><div class="slideshow_outer"></div></body></html>" baseURL:nil];
[_webView setNeedsDisplay];
The first is the website address
The second is the part of the HTML I want to load
and the third is to display it.
I get an error on the HTML string I put. How do I fix this or is there a better way of writing it?
It won't work, how do I go on with this?
// show HTML content in webview there is two different types, as follow
// 1. Using URL
// for show web view with online url
[_webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:#"http://jlhs.schoolloop.com/mobile/login"]]];
// 2. Using string
// for show web view with help of string, local page
NSString * htmlPage = #"<html><head><meta http-equiv=\"Content-type\" content=\"text/html charset=UTF-8\" /><meta name=\"viewport\" content=\"width=device-width; initial-scale=1.0; maximum-scale=1.5; user-scalable=0;\"/></head><body style=\"font-size:13px;font-family:Arial;-webkit-user-select:none;\">Write here your HTML content </body></html>";
[_webView loadHTMLString:htmlPage baseURL:nil];
// you can't use it at a time, as per your requirement use one of these.
I hope you undersand want I want to explain.

I have an iPhone app that has a Twitter page tab... however, every time someone goes to it... it loads the following splash page, I can't figure out how to remove this splash screen when loading a twitter page?
My current code is
[webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:#"http://twitter.com/TwitterNAME"]]];
I would prefer not to use a table view to show tweets...
Just append this string to the URL: ?skip_interstitial=true, so it results as:
http://twitter.com/TwitterNAME?skip_interstitial=true
Probably you wanna format a string with the whole URL structure:
[NSString stringWithFormat:#"http://twitter.com/%s?skip_interstitial=true",TwitterNameVar]
Resulting something like:
[webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:[NSString stringWithFormat:#"http://twitter.com/%s?skip_interstitial=true",TwitterNameVar]]]];
I'm trying to make a WebView load a page from HTML code I have stored as an NSData. I get a blank page when I try to do this. Is there anything wrong with what I'm doing when I load the page? If not, I need to look elsewhere in my program.
if (essence.html){ //essence.html is an NSData
NSLog(#"Inserting HTML code into browser window: %#", [[NSString alloc] initWithData:essence.html encoding: NSUTF8StringEncoding]);
[webView.mainFrame loadData:essence.html MIMEType: #"text/html" textEncodingName: #"utf-8" baseURL:nil]; //webView is a WebView
}
I created the conditions so essence.html contains HTML code from the page http://kathleenmelian.com/test.html (which just says "hello"). The NSLog prints this when the above code runs:
Inserting HTML code into browser window: <html><head></head><body>hello</body></html>
So essence.html definitely contains valid code that a browser should be able to load.
You could use
[webView loadHTMLString:
[[NSString alloc] initWithData:essence.html encoding:NSUTF8StringEncoding]
baseURL:nil];
The other idea would be to replace "utf-8" with "UTF-8", which in some cases is known to make a difference (not sure about UIWebView).
Sorry to bother you guys. I fixed some other bug in my program's model, and that somehow fixed THIS problem as well. I don't know how. Crisis averted.
i want to take a normal html page (a page from tf2 wiki) and convert it into a view.
For example it should take a text and put it into a label or a Image into an UIImageView.
Is there any Framework to do something like that or should i convert the site on a webserver
to make it easier for the app at runtime to render ?
Hope you understand, what i want to do.

there could be different ways depending on your scenario, you could load them in UIWebView within IOS, If you don't want show the UIWebView then you can get the html from it ans use it however you want. or other way you could transfer the HTML as json data to IOS and then show that data via UIView, UILabel or anything else. otherwise as suggested by Zakaria, you could use PhoneGap.
UPDATE with sample code for sending a request and getting its contents if you don't want to use UIWebView
//your html page with url
NSURL *url = [NSURL URLWithString:#"www.google.com"];
NSURLRequest *request=[NSURLRequest requestWithURL:url cachePolicy:NSURLRequestReloadIgnoringLocalAndRemoteCacheData timeoutInterval:30.0f];
NSOperationQueue *queue=[[NSOperationQueue alloc]init];
[NSURLConnection sendAsynchronousRequest:request queue:queue completionHandler:^(NSURLResponse *response, NSData *data, NSError *error) {
if ([data length]>0 && error==nil) {
NSString *html=[[NSString alloc]initWithData:data encoding:NSUTF8StringEncoding];
NSLog(#"this string contains all html page you have \n %#",html);
}
}
];
Not sure if i understand the question properly, but Cordova lets you develope iOS apps in html/css/js.
Check their website: http://cordova.apache.org/
If your page is a static one, then use PhoneGap : It will embed your HTML+JS+CSS in an iOS app and will be loaded in a webview.
But there is no framework that will allow you to convert your HTML elements into native ones.
I have a requirement for my project . I want to generate html file dynamically from the user
inputs. I have searched a lot , but I couldn't find any links for this.Any help on this ?
I have done similar thing. I think what you need to do is. create a template html page with container divs with id and load that file. On the delegate method of webview onPagefinishedloading run java script to add the information dynamically on the divs to the template html page.
NSBundle *bundle = [NSBundle bundleForClass:[self Class]];
NSString *htmlPath = [bundle pathForResource:#"html file name" ofType:#"htm"];
NSString *htmlContent = [NSString stringWithContentOfFile:htmlPath encoding:NSUTF8StringEncoding error:nil];
//Do your HTML edits here
[[self webView] loadHTMLString:htmlContent baseURL:nil];
I am trying to pull down the code from an HTML website that has no more than 2 lines on it. The code contains a word that I need to retrieve. Is there a simple way to pull down that code and put it in an NSString?
Further details: I am going to have an app that checks for a word on a page. If that word is what I am looking for, the app will show the text "confirmed". The purpose of the app is to check to see if the page is accessible.
If you need a http library to hit the server try asihttp. Apart from this i need more info of what you are trying to do...
If you just want to check if that website is reachable, you can go with HTTP Success Status Codes.
Using ASIHTTPRequest simplifies communication over the web.
If you still want to evaluate the text on that website, can also just retrieve it using:
[request responseString];
Depending on what you get from the website, it's up to you how to update the UI.
Just change the link between the quotes and it'll work!
-(void) viewDidLoad {
NSString * sFeedURL = [NSString stringWithFormat:#"http://www.google.com/ig/api?weather=,,,270000,960000"];
//RSS Feed URL goes between quotes
NSString * sActualFeed = [NSString stringWithContentsOfURL:[NSURL URLWithString:sFeedURL] encoding:1 error:nil];
NSLog(#"%#", sActualFeed);
}
