I'm looking at how to make a very simple browser in my app. Only need reload, back, forward, etc.
Does anyone have any simple code they can add here?
I have a tableviewcell that when clicked will launch this view.
Add a UIWebView.
You can use
[webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:#"http://www.google.com"]]]`
to open a website, -reload to reload, – goBack and -goForward to go back or forward.
Check out the UIWebView API, which is basically a WebKit rendering widget - the one that also powers iPhone's browser app.

I am opening many urls from my application and they are working fine. All these urls I am opening in UIWebView in a custom ViewController.
But recently I found an issue that when I am passing a url which contains a PDF, it opens fine , but when I copy something from that PDF by long pressing on the PDF from UIWebView, and then when I try to go back from that ViewController, the app crashes giving me error like:
[UIPDFPageView nextResponder]: message sent to deallocated instance
Without copying any thing I can normally go back and continue with my app. I tried a lot but could not figure out the problem.
If any one can help, It will be honor.
Thanks in advance... !!!
I guess you might be calling the below line when going back from your UIWebView's ViewController :
[webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:#"about:blank"]]];
May be to clear out your WebView before leaving. There are better and easy ways to so this like given here:
Hope this helps...
All the best!!!
I have a native iPhone app, which has a UIWebView component to it. I am trying to see if I can replicate the "Add to Home Screen" button that is present in the tab bar options in Safari.
Is this possible inside a UIWebView within a native app?
Thanks!

[I presume your question is about replicating the action associated with add to home screen, rather than replicating the appearance of the button itself (which being pedantic is what you actually wrote).]
As others have said this isn't possible.
What you could do is programatically launch Safari from within your app and give it the URL of a page to load which is your page.
When your page is loaded it has some sort of animation and shows the user where the add to home screen button is and tell them to press it after clicking a link which is displayed in your web page. When the users click on the link it takes them to whatever page it is that you would like saved to the desktop, and you hope they follow your instructions.
If you register your app to handle a proprietary url scheme the users can get back to your app from within Safari by clicking on a link using your app's url scheme.
The web pages that you seed Safari with must however be remote pages, you cannot give Safari a page in your app's bundle or that your app has downloaded as Safari cannot read pages from your app's sandbox.
The short answer is no, you can't. Apple does not let you.
Here's a similar question which may help you come up with other possibilities:
Javascript for "Add to Home Screen" on iPhone?
If I had to think of a work around off the top of my head, you could create an javascript pop-up which instructs them how to. It could say something like tap this button to go to mobile safari then tap action -> add to home screen.
Execute the Javascript with UIWebView's method:
- (NSString *)stringByEvaluatingJavaScriptFromString:(NSString *)script
Hope this helps.
You can use UIActivityViewController with your url as the activity items
NSArray *activityItems = #[title, url];
And then you can exclude the activities that you don't want. I think it´s the only way for now.
such that when the user open the application the website referenced will be loaded in the web browser
I know the code the will open a URL with in an application
[NSURL URLWithString:#"http://www.apple.com"]];
But this is not what I need I need the application to display the web browser within its form.
If you are only to show one page I suggest you should use ModalViewController to present the page inside your app and put a UIWebView in it.
If you are to render the web page as an application than you should use UIWebView
If you want to present some pages but also want to make use of navigation functions of the safari inside your app you can use DLWebView framework which suppors ModalView with navigation function.
Here you can watch the video how it works: http://dlinsin.github.com/2011/04/24/DLWebView.html
You need UIWebView class : UIWebView Class Reference
Also you can try to search for a ready webview with all needful buttons.
Have you looked into UIWebView?
If you need browser functionality within your own app, you will need to create your own, i.e. it's not possible to embed the Safari browser within a view in your own app.
We have a wifi hotspot that displays a terms of service page before people are allowed to start using it.
After acceptance, a new page with a few links is displayed. I'd like to have those links open in Safari instead of in UIWebView.
I know there's a way to program UIWebView to open links in Safari, but that's not an option as this is the default UIWebView for logging into wifi hotspots and not a custom app.
Is there another way to have the links open in Safari and not in UIWebView? I've tried javascript and I've tried setting the target to _blank.
EDIT: After reading some responses, it seems like the only way to do this is to set the UIWebView delegate. I don't think this is an option because I'm not the one launching the UIWebView.
When the iPhone connects to the network (at least with version 3.0), it checks to see if it's being redirected to a login page. If it is, it does what you're saying with authentication and such inside of a UIWebView. Have you checked to see what it's reporting as the browser in use? If it isn't Mobile Safari, then you could do something server-side the first time someone connects using Mobile Safari.
If it does report as Mobile Safari when it's checking redirection, then another alternative is to figure out what site it tries to go to - maybe apple.com? Then, on the server side, the first time a different URL is loaded, redirect to your links. This will only work when the user opens Mobile Safari, however.
Other than that, I think what you're asking to do is outside of the scope of the current iPhone OS. I'd recommend filing a ‘feature request’ with Apple at bugreport.apple.com.
The only way I know how to do this is to set up a UIWebView delegate and supply something like the following:
- (BOOL)webView:(UIWebView*)webView shouldStartLoadWithRequest:(NSURLRequest*)request navigationType:(UIWebViewNavigationType)navigationType
{
if (navigationType == UIWebViewNavigationTypeLinkClicked &&
[request.URL isFileURL] == false)
{
[[UIApplication sharedApplication] openURL:request.URL];
return NO;
}
return YES;
}
The code above will cause Safari to open a link clicked on by the user. I know you said you had little control over this UIWebView -- perhaps you have more than you think by setting the delegate?
Use the openURL method of UIApplication:
NSURL *url = [[NSURL alloc] initWithString:#"http://example.com"];
[[UIApplication sharedApplication] openURL:url];
[url release];
An Apple example of this is available as part of the LaunchMe sample.
Is it possible to Launch Safari without having the app close? Just like the in-app email compose window.
I'm aware of how to display a webpage in UIWebView. I'd like to use a full web browser, i.e. Safari.
You can use a UIWebView to display web content in your app.
You can create a UIWebView with the URL to display. It will follow any links that the user touches, but that won't give you the address bar, search, navigation buttons, bookmarks or the page (tab) control. Those you'll have to add yourself, but odds are you don't want all of that. (Do you really need Google searches in your app?)
Creating a controller to manage a UIWebView and as much or as little navigation as you need is pretty easy. With a little planning, your custom controller class will also a good thing to keep in your library for the next app.
No you can not make use of the full Safari from within your own application. Your application must terminate for Safari to open.
In iPhone OS 2.0 you also had to terminate in order to send e-mails, so some chance exists that Apple couls open up Safari in the same way for iPhone OS 4.0. Make sure to request it at http://bugreport.apple.com if you are eager.
The second best option currently available is to roll your own "Browser view controller" using UIWebView. Let it have back, forward, stop/reload buttons, and an extra button for opening in Safari if the user is not content. This is how many of the greatest apps our there, like Tweetie, does it.
