i'm developing an app that will be just a wrapper for a certain book
the book is in HTML so, i want to make something like stanza,
i want to determine no. of pages given the Whole book HTML and to paginate that dynamically into views.
is there any built-in methods that can help me with that?
or
does anyone know any idea of how that can be done ?
If you only need to do this once: insert some javascript into the HTML to tell you the height of the document once it's done loading, e.g.:
alert(document.height);
and divide that by the height of your web view to get the number of pages.
You can use UIWebView to load the data, and leave the navigation/link code to paginate in the HTML.

How do you use an ajax script on an iPhone app?
I have a jquery script on my webpage that i would like to be on the view controller for my new app.
<jquery...code...>
Lets pretend the above is the jqueury code. How would i port this over to the iPhone view controller? Thanks sorry the question is so simple.
(all the code does is display a loading box that spins around and around and its quite pretty. Im probably going to put an image inside it )
Unless you're using a UIWebView in which case you simply embed a web page (including the JS code) into your app, jQuery (or rather Javascript and the DOM) is completely distinct from Objective-C and Cocoa Touch, so you can't use it, and the only option is to rewrite the same code in the new language and framework.
I want to show all the contents from .ePub file to UIWebview with pagination(horizontal scrolling). For that i need to find out total content size that,each chapter contains, page size..
I'm not at all clear about how/where should i start. I don't know how to use stringByEvaluatingJavaScriptFromString to call the methods. Where should i write the function definition which is called using stringByEvaluatingJavaScriptFromString. Please anyone give me a step by step procedure for UIWebview pagination. There may be same question but i didn't get any clear explanation.
Explain me Step by step JQuery procedure
Thanks in Advance.
You can find good example of parsing and displaying ePub here. It does not use JQuery, only javascript.
Im planning on adding a instructions view to my app. Whats the best way to do it? Load a PDF into a webview or..?
Please suggest anything I might find helpful.
I also want it to look good for the user, not to plain.
You might want to consider using a UIWebView to load content that resides on your web server. The downside is that the user needs network connectivity to see the instructions and you need to know your way around at least some web development. However, you'll be able to use HTML+CSS+Javascript to create interesting content and you'll be able to change/update/correct that content without going through the hassle of releasing the app again.
I've seen a few apps put screenshots into a scrollview with a paging control. I really like that design, and there are plenty of tutorials online that explain how to do this.
You can implement instruction view different ways:
1) Just put textview and make scroll. (very simple)
2) Design the HTML instruction, and load it to the webview. (medium in look vise)
3) Create attractive design for instruction pages and implement scroll view with pages. (very attractive)
Please review above point and let me know in case of query.
Thanks.
I would use a info button (the lowercase "i" button, can be accessed by inserting "Round Rect Button" and changing type to one of the "Info" buttons or in code you could init a button with type: "UIButtonTypeInfoDark" or "UIButtonTypeInfoLight") on your main or first view controller. Inside that view you could put an UITextView with editing OFF and that would contain all your instructions that the user could scroll through and get to quickly, easily, and intuitively
I have an rss feed with only one item in it.I am trying to go straight to showing its details without having to go through a table view to do it.
I have a different rss feed working in my app that has multiple items. I have this working with a table view.I was looking online and all I could find was how to display a feed through a table view.
Does anyone know how to display the singular item from the feed in an app?
or of any online tutorials?
Any and all help much appreciated.
Just parse the feed and insted of showing in tableview ,show it in a label or textview .
I don't understand what u trying to ask through your question. It sounds simple but can you elaborate or give url of Rss feed links for understaning ur query...
If you've parsed your data already, you have it stored in a set of variables, right?
So now you just want a particular data to display in detail view for this if you use (UIWebView for DetailView) used this or a particular you wish to publish in the details view:-
– loadHTMLString:baseURL:
Sets the main page content and base URL.
- (void)loadHTMLString:(NSString *)string baseURL:(NSURL *)baseURL
Parameters
string
The content for the main page.
baseURL
The base URL for the content.

I'm trying to use the printing stuff in iOS 4.2 to print from my iPhone app, but I'm having real trouble getting multi-page content to display nicely. As you can see in the attached screenshots of PDFs generated through the iOS printing API, UIMarkupTextPrintFormatter really likes to use a painfully small top-margin when rendering.
Additionally, it doesn't seem to try to split block-elements too nicely either ... it's tough to see in the screenshot but the page break actually occurs halfway through a table row, rather than on a border between rows.
I've tried using the CSS #page directives to specify page boundaries, however iOS Webkit doesn't seem to support these at all.
Does anyone know of any techniques, either in HTML or through the iOS SDK to make these top-margins bigger?
I really don't want to write a custom UIPrintPageRenderer class because I'm trying to give my users the ability to customize their printouts through HTML templates ... going with a custom renderer would almost certainly make this impossible (or really difficult).
Any help is much appreciated!
You're on the right track with UIPrintPageRenderer, but fortunately you don't need to write a custom subclass to do this. All you need to do is instantiate a vanilla UIPrintPageRenderer, set the headerHeight and footerHeight properties, and add your HTML formatter to the renderer using addPrintFormatter:startingAtPage:. It only takes a few extra lines of code, I have posted my method here: Print paper size and content inset
