I am working on a small app, which can open a pdf. My question is, if it is possible to access a hyperlink from a pdf? Because when am trying to click on hyperlink nothing is happening and it's not redirecting me to the link. I tried searching a lot but didn't got any luck on this. Am expecting a quick response as my work is getting delayed because of this issue. If it's possible then what would be the approach? Right now am using UIWebView to open the pdf. Any sample app or code will be of great help.
Thanks for your time .
The only way I know is to use a third party library (or perhaps parse the PDF yourself), find the links, get their rects and catch user taps and compare that to the list of link/hyperlinks/gotos for that particular page.
Unfortunatelly - nothing in the SDK that can help. You can search for a opensource pdf library, like muPDF for instance.
There is a reason why not many applications have that functionality :D

I'm fairly new at iOS development so please forgive my ignorance.
I have web view with a search form, sending request to display different pages depending on the search query. When displaying a selected page I want to have a normal html link at the top which will give the user the possibility to display all images available using the very nice MWPhotoBrowser.
So somehow I need to tell Xcode to open MWPhotoBrowser using a link and when this link is pressed send a variable to MWPhotoBrowser and in that viewController somehow loop through a my url.com/variable.
Is this the best way to do this and is it even possible? I have searched as much as possible but I'm not sure what to look for so I would really appreciate if you could point me in the right direction.
Judging from this link at github project it should be fine.
I am very interested in building an app like http://brdrck.me/settings/. My first questions are what is inside a web clip file? Is it a html or something else? The second question is how to add the icon to home screens programmatically. As you can see from the page I mentioned above http://brdrck.me/settings/. I tried to check its source code from browser but it turns out to be some normal CSS and javascript code in my Chrome browser and I don't know how to check the source in my Mobile Safari. Any one help?
You won't be able to get any valuable code from the source. Trust me. :D
But, I can help you out.
I use two different methods: The "Add to Homescreen" and .mobileconfig files (the one you have to install)
For adding to the homescreen check out this resource. With the help of some creative work-arounds, it isn't too difficult.
http://mobile.tutsplus.com/tutorials/iphone/iphone-web-app-meta-tags/
The mobileconfig file is a bit more difficult, esp trying to get it signed, but this might help you a bit. Try to create one with a webclip then view the generated files source: http://support.apple.com/kb/DL1465
Hope this helps.
Is it possible to get the page number and line number of particular text from doc/rtf/pdf in iPhone sdk?
Can QLPreviewController or UIDocumentInteractionController be of any help?
EDIT:
I am trying to create something like iAnnotate,Sente. Application where in user will be able to select some text and can add comments for selected text.
I have gone through the fastpdfkit api's which seems the only api which can be of some help.
Can you guys guide me in the right direction.

Go with this link, it will help you for PDF reader and you can see there how I am doing total page and current page.
If you're looking at doing this with PDF, RTF and DOC it might be best to approach it in a different way as they are all very different formats.
Instead - if you consider attaching comments to an area of the page as opposed to a specific text selection then all you need to know about the document is which page you're looking at. A much easier task. Then you get the user to 'drag out' a comments box for an area of that page. Think of them more like sticky-notes.
This way you can add comments to images as well as text and it allows a much more flexible system for support of other file formats in the future.
I realise this isn't I direct answer to the question, but thought it relevant enough to post.
Is it possible to create a hyperlink in an sms in an iPhone?
For example, if I want the word 'foo' hyperlinked in HTML then I'll write foo in a normal situation.
If I want to have a certain word in my sms to be hyperlinked to something, is there any way I can do this? Like "I have a surprise for you" and the receiver taps on the hyperlinked word 'surprise' which will take the user to the destined page.
Any suggestions as to how this can be done? Examples and samples welcome!
Thanks in advance :)
No, you cannot use html tags in sms / text messages. All you can do is insert the URL without the tag. It then depends on the receivers device whether the URL is presented to the user as link or as plain text.
I experimented with exactly this just yesterday. It seems you can't include a nicely formatted hyperlink, unfortunately. I hope to be proven wrong by somebody else, though :-)
However, as you've probably seen yourself, iPhone is able to recognize an URL and you can tap on it to open the URL in Safari (or tap the disclosure button next the message to get more options on what to do with the URL). As far as I can tell the only thing you can do is format your SMS accordingly: "I have a surprise for you: http://foo.com" even though that might spoil the surprise ;-)
No, you can't do this due to privacy issues. Apple thinks that giving you this ability would allow you to link users to malware and such. Sorry!
i don't think it's possible to create hyperlinks in SMS.
The only way is to send an URL, and the iPhone will convert it to a link...
Use a tiny url from tinyurl.
It doesn't allow you to do exactly what you are wanting but it at least can be used to cover up the long link.
This is the closest thing I figure out to do. I was wanting to use the "
No, you can not do this. However you could use tinyurl and format it like this

Web browsers usually ignore anything before an # therefore you could effectively hide the actual site being linked to, as long as your friend does not know that.
What actually happens is the data before the # is submitted to the web site in the form username:password. However it must be a site that requires authentication to access, or the site will normally just ignore it.
If this helps, I've noticed that a custom hyperlink is possible on the OS X Messages app, but they have to be copied and pasted. To replicate this right click on a hyperlink in your browser and hit copy link. Then paste into Messages.
Uhhh this is possible here is a screenshot of an example - I copied a link from email and pasted in a new SMS - though it appears you cannot type html to create a link....
I need to perform search in an html page displayed in a UIWebView control. The functionality I need is something that Safari has, when you hit command/ctrl F for searching the document for some word and the program highlights the hits for you. Is there any easy solution for this problem?
I know it's been a long time since you asked this question, but it's still a pretty common question people have so I put together a sample project in case anyone else is asking the same question. The project is a super simple app that loads an HTML file and can search and highlight any keyword. You can download the sample project here:

Edit: changed link above as the old one had broken.
You could do this with javascript. Check out the "Find in this page" bookmarklet:

Something like that, combined with:

might do the trick.
