For legal reasons, I'm obligated to show Terms of Service in my application, a PDF on an external server. What I believe would be easiest to do would be to create a UIBarButton item and then create an IBAction that launches the link in Safari.
So I create a button:
IBOutlet UIBarButtonItem *legal;
Then I make it into a nonatomic property and synthesize it in my implementation file, right? I go on to create an IBAction:
-(IBAction)legalButtonPressed:(id)sender;
I go into my implementation file, and here's where the issue comes. When it comes to defining those actions, I become confused. As I am new to iOS development, I could use some guidance. I don't know how to force the link into safari in the action. Any help would be greatly appreciated!
Thanks!
IBOutlet and IBActions are used for Interface Builder connections. If you have your UIBarButtonItem on a xib file, you can connect its action to the controller by right clicking in the files owner object. The same with the outlet.
Once you have the action in the controller connected to the button in the xib file, (I see no need to get an outlet here), you just implement the method as follows:
-(IBAction)legalButtonPressed:(id)sender {
[[UIApplication sharedApplication] openURL:[NSURL URLWithString: #"http://yourdomain.com/legal.pdf"]];
}
this will automatically open safari with the given url
Take a look at UIApplication's documentation, it has a openURL method you might find useful.
Another option is to include your legal text in a UITextView.
Example:
By clicking Join you agree to company's
Terms of Service, found here: http://www.site.com/tos.html and
Privacy Policy, found here: http://www.site.com/privacy.html
Make sure Link Detection is turned on in the UITextView and it will automatically recognize URLs. Any clicks on those URLs will automatically launch Safari.
Although you can do this approach (i.e. launch the link in Safari). I would suggest that you try to keep the user as much as possible in your app. I am guessing this LEGAL TERMS is a HTML doc?
You can do that using UIWebView. Init a webView and do this -
NSURL *url = [NSURL URLWithString:webAddress];
NSURLRequest *req = [NSURLRequest requestWithURL:url];
[webView loadRequest:req];
This will open the url in your app only! You can make the UIWebView open up as a modal window or in many other ways...

Here we are using UIWebview related application.
while clicking on some links, it's automatically connect(go) to the itunes.
but it's cannot get back to the app after clicking a itunes link (with out clicking on Exit).
My Question is, how can come back to the app after clicking a itunes.
Try this one uiwebview delegate method.
-(BOOL)webView:(UIWebView*)webView shouldStartLoadWithRequest:(NSURLRequest*)request navigationType:(UIWebViewNavigationType)navigationType
{
NSURL* url = [request URL];
if (UIWebViewNavigationTypeLinkClicked == navigationType)
{
[[UIApplication sharedApplication] openURL:url];
return NO;
}
return YES;
}
I usually insert a button next to UIWebView.
Use a new view and insert button in any corner of view and then put your UIWebView, set your uiwebview is not fit to screen so you can push to exit button. When you tap to button than hide your view. ITs usually what i do for such situation, maybe it can help to you
When you click on any link and you now go to at this link of page and if you want to go previous to your application. Generally You can not go Back to your Application because Apple iOS does not provide this types of feature.
I am not sure but It may be possible in JB Device.
you can add custom tool bar at the top of your view and add back button to custom tool bar to come back to your app. Below to custom tool bar add your webview.Hope it will helps you.
If you are loading the webpage with Safri or you are opening iTunes app with custom schema, it is not possible, because you are leaving the app.
But yes you can do this, If you will load that itunes connect link through web view, and there you can place a custom back button to come back to your previous page.
For Example :
UIWebView *webView=[[UIWebView alloc]init];
[self.view addSubview:webView];
[webView loadRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:#"http://www.xyz.com"]]];
My app needs to open some file types in other apps, like dropbox app does, it could list the installed apps which could open specific types of file.
How can get the app list?
You'll want to use UIDocumentInteractionController. See also the Document Interaction Programming Guide.
You can use QLPreviewController from the official docs.
Expanding on jtbandes's answer, here's the code that worked for me:
NSURL *url = [NSURL fileURLWithPath:filePath];
UIDocumentInteractionController *popup = [UIDocumentInteractionController interactionControllerWithURL:url];
[popup setDelegate:self];
[popup presentPreviewAnimated:YES];
And don't forget to include this in your H file:
#interface MyViewController : UIViewController <UIDocumentInteractionControllerDelegate>
Also worth noting: this will open a new fullscreen view that has a Document Viewer, as well as the Share button that offers all the various apps that can open this file. If you're just looking for the Share popup, equivalent to the UIActivityViewController, this will do it, but with some extra functionality you may not want.
For a current project I am embedding a mobile site into an iOS app. I've taken use of the goback() and goforward() functions, with UIWebView. But how would I make a custom function that onClick (or onTouch which ever is the correct term) Sends the UIWebView back to the page initially loaded? Any Help would be much appreciated as I have bene unable to find anything on the web thus far.
Add something like to the implementation file:
- (IBAction)loadPage:(id)sender;
{
NSURL *url = [NSURL URLWithString:#"http://www.stackoverflow.com/"];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[webView loadRequest:request];
}
And add this to the header file (each line at the appropriate position):
- (IBAction)loadPage:(id)sender;
IBOutlet UIWebView *webView;
Then bind the button to loadPage within interface builder,
and bind webView to the UIWebView.
Response to comment:
I created this sample project, hopefully it helps:
- http://dd5.org/static/iPhone_Browser_Sample.zip
Binding the button:
Right-click and drag to the class where you added the code above.
Release the button. Now a little dark-gray panel should appear.
Then click on the loadPage: entry within that panel.
If the code was added correctly, the entry should show up there.
1) user launch application
2) user press button
3) button loads http://domain.com/mypage/?item=123
How do you trigger http://domain.com/?item=123, without opening the actual page in the browser?
NSURLConnection is the answer.
Not 100% sure of what the question is, but you could use a UIWebView. Load that UIWebView in the app with the URL and you should be good to go.
Hope this helps!
NSString* str = [NSString stringWithContentsOfURL:[NSURL URLWithString:#"http://domain.com/?item=123"] usedEncoding:NULL error:NULL]
I have used a UIWebView set to "hidden". It probably is not the most efficient way but if you normally use UIWebViews and Interface Builder then it is easy. You can also use the webview delegate methods to watch it.
On second thought - use the NSURL String method above but put it in a new thread.
In my app i want to put my website's url on home screen and on clicking on it i want it to be open as a WebView.
How should i go for this.
Thanks,
Previous commenter is incorrect. You can open any hyperlink either externally with Safari or internally with a UIWebView.
Add a UIWebViewController to your project. Then, instantiate an instance of a the UIWebViewController that will be shown inside your app--you'll do this by declaring a property & synthesizing it within your main view controller (which will need to be declared as a UIWebViewDelegate), such as:
#interface MyMainViewController: UIViewController <UIWebViewDelegate> {
// Your implementation code here
}
When a user taps the button (assuming you make it a button, rather than just a text hyperlink), you instruct your app to add the UIWebView to the view stack, loading the correct link. You'll want to either do this within a modal view or within a navigation stack so your users can get back out of the web view, of course.
In your MyMainViewController implementation file, something like this:
-(void) showWebView {
// NOTE: I have not tested this, just prototyping
// off the top of my head
UIWebView *myWebView = [[UIWebView alloc] init];
myWebView.delegate = self;
NSURL *homeUrl = [[NSURL alloc] initWithString:#"http://example.com"];
NSURLRequest *homeRequest = [NSURLRequest requestWithURL:homeURL];
[myWebView loadRequest:homeRequest];
[self.presentModalViewController: myWebView animated:YES];
// Don't forget to release objects when you're done
[myWebView release]; // etc.
}
Now, this is off the top of my head from what I know and have done. But I hope you get the general idea. I offer no warranty of any kind here, but do guarantee this is entirely possible with minimal headache. If you get stuck, check out the developer references for UIWebView. Apple's docs are top-notch & show great examples to get you up and running quickly.
Best.
