If I touch urls on UIWebView and hold 2, 3 seconds, it will display an option window for url with items:
Open, Copy
Is it possible to change the items or add new option? Such as
Open, Copy, Download
Welcome any comment
Not using UIKit's built in UIWebView, no. The only way to do this would be to rewrite/subclass it, but that's going to be a massive pain.
Note: Open and download are basically the same thing in iOS.

I want to make "Open in.." function in my iOS application.
Is there any way to check if any app on this device is associated with file extension that i want to share?
If there are no apps on current device to open file with such an extension than UIDocumentInteractionController will not be displayed after clicking on "Open in.." button, but i want not to show this button in such case.
So the question is: how to check if any app on device can open some file with specific extension?
Update:
For example UIDocumentInteractionController has NSArray property icons.
It contains images of all aplications that can open the file with my extension. But if there are no applications it contans image of empty application.
So i can't check it using docInteractionController.icons.count == 0 for example. I am looking for other tricks.'
Thanks, in advance.
Although UIDocumentInteractionController does not offer a way to discover in advance whether there are any applications that can handle a document, -presentOpenInMenuFromRect: will return a flag indicating whether there were any applications that could open a document. This requires you to have already set up and presented the controller, which is not optimal.
There is a workaround for this, a little hacky but is functional: Before you invoke the "real" interaction controller, create a dummy one using a dummy document, and present it from the rect of the window's bounds. This guarantees that it will "appear" offscreen, so your user won't see it. At that point, you have the flag returned from -present, and you can immediately dismiss the dummy controller, and the proceed to show your UI appropriately.
On OSX, you can get a list of application bundle identifiers capable of handling a specific content type using LSCopyAllRoleHandlersForContentType. But on iOS, I don't think there is such a way.
If I find, I'll edit my answer.
Considering you are looking for other tricks, you can check if that one image in the icons array is the generic document icon.
If it is then you know that there is no app associated to handle that file type. But this approach will be OS version dependent as generic file icon may change.
From the official documentation:
To declare its support for file types, your app must include the
CFBundleDocumentTypes key in its Info.plistproperty list file. (See
“Core Foundation Keys”.) The system adds this information to a
registry that other apps can access through a document interaction
controller.
To me this indicates that the registry can only be accessed through UIDocumentInteractionController and so no, you would not be able to know in advance if there are any available apps for the file format (which would be totally in line with Apple's philosophy of not letting apps interact directly with each other).
UPDATE:
as you said the icons property contains an image even with no applications present. I checked and all the other methods and properties of the controller do not give an hint about the apps that may open the current file format.
You said in case that no app can open the specified file format there is an "image of empty application". Maybe you can extract that icon and when the array icons only has one image check if the extracted image and the icon are the same?
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.
I know how to open an URL from app in Safari using [[UIApplication sharedApplication] openURL:url];. This is great, but what I need to do is that I have multiple URLs and I want to start Safari with more tabs opened with those URLs.
I tried calling openURL multiple times but it just opens Safari once and other urls are ignored.
Is there any way of opening multiple tabs in Safari from my app?
Thanks.
When you call UIApplication openURL:, your application will be put in the background and will no longer be allowed to perform these operations. I do not think that opening multiple tabs is something that iOS Safari supports. Tabs are probably implemented in a more memory-efficient way (i.e. loading only the tab you see, saving a picture of the others until you switch to them). It would help knowing why you want to open multiple tabs.
Some suggestions:
Open a link to a "launcher" page, which takes you to the page you want
Use UIWebView and implement the tabs yourself
Create a menu of some sorts in your app, opening only one page at once
i am making an app for iphone and for that i am using certain free libraries.My problem is that i want to show their complete license of nearly 4-5 pages in my application bundle so that a user can open settings in iphone and see that licensing page at one time but i am unable to do it.I have read these Specifiers for making an application bundle .
PSGroupSpecifier
PSTitleValueSpecifier
PSTextFieldSpecifier
PSSliderSpecifier
PSToggleSwitchSpecifier
PSMultiValueSpecifier
PSChildPaneSpecifier
but i want to show a page full of text like Settings->General->About->Leagl
just like in iphone through PSChildPaneSpecifier .Please help me how to do this>???
Thanks
You can create the same effect as used by Apple's iWorks apps for the license > section of the settings, without using any custom preference controller. Note this works for iOS 5 on the iPad, I have not tried it elsewhere. Use a PSChildPaneSpecifier for the initial control in the root plist. This points to the name of another plist file which will be the displayed child pane. You do not add .plist to the name within the root.plist file, it is implied. This plist file must be within the settings bundle. Next, use PSGroupSpecifiers in the child pane as the controls. For each paragraph use another PSGroupSpecifier - so the thing will scroll. Only use the Title section of the PSGroupSpecifier. The next gotcha that I found, was that by putting the strings in the plist file, the text was clipped in portrait orientation, so a placeholder string needs to go in the plist file and a StringTable used to point to a strings file. Text read from the strings file is properly kerned and displays without clipping.
The iPhone's "Legal" page is a custom preference controller which you can't use (not even with undocumented methods – you need to write a preference bundle in system locations which AppStore apps can't reach at all).
If you'd like to display the license, show it in the app.
I think you are going to need to use something like a UITextView, just make it non-editable. You can make in unobtrusive in your app but I think that is the only way to have 4-5 pages.
I don't think there is a nice way of displaying this in the preferences bundle. Personally I would either provide a series of url links or bring the preferences into the app itself. There is a good framework on github here that you may be able to modify.
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.
